Hoshizaki recommends that the ice machine drain andbin drain be piped separately to the drain connection pointallowing 1/4" per foot fall.
CONDENSATE DRAIN -
The condensate drain is generally connected to the icemachine drain for simplicity. It can be piped separately tothe drain exit if desired.
A 6" vent tee is recommended as per drawing:
FLOW RATES -
The minimum flow rate requirements for Hoshizaki icemaker units are as follows:
KM-250/280/AII Flakers 1.05 GPMKM-500 1.58 GPMKM-630/800/AII DCM's 2.11 GPMKM-1200/1600 3.96 GPMKM-2000/2400 4.23 GPM
Use this information when sizing a filter system for the icemachine application.
NOTE: A good rule of thumb is to utilize a 3 GPM flowrate filter for KM-250 through 800 and a 5 GPM flow ratefilter for KM-1200 or larger.

Transformer ApplicationAll 3 phase models include a 115V transformer with a 208/230V selector switch. Be sure to select the position thatbest matches the in-coming voltage prior to supplying powerto unit. (Voltage from the center tap to case ground willread 67.5V due to transformer circuit.)
208-230V models include 115V controls. They require a115 / 208-230V circuit which has 4 wires including L1, L2,dedicated neutral, and gnd.
If a dedicated neutral is not available or the previous unitused a 3 wire circuit (L1,L2, & gnd.), a step-down trans-former can be used at the unit to provide power to the115V components. This will save on installation time andcost if a dedicated neutral is not present.
Transformer # 4A0817-01 or equivalent can be used forKM models. Transformer # 446240-01 or equivalent canbe used for F-1000 models. This transformer should bemounted inside the compressor compartment and wired

LINE SET INSTALLATIONA universal line set adapter kit, part number OS-QUICK, isavailable if you need to field engineer your line set. Bothlines should be insulated separately the entire length ofrun.
The refrigerant charge for a new unit is distributed be-tween the unit head and the URC condenser. The line sethas a minimal holding charge of 15 to 30 psig refrigerantvapor.
If you need to field engineer your line set or shorten/lengthen a precharged line set you can do so by followingthese steps:
1. Using the OS-QUICK kit, braze the line set connec-tions. (If you shorten or lengthen a precharged lineset, recover the holding charge, cut or lengthen andbraze the connections.)
2. Pressurize the lines and leak check all braze joints.
3. Evacuate the lines through the service ports on theAeroquip quick connect fittings.
4. Charge both lines with 15 to 30 psig R-22 vapor.
To make Aeroquip connection to the unit head and con-denser:
1. Lubricate the threads and O-ring with cleanrefrigerant oil.
2. Tighten the female connector until it bottoms out.
Note: Be sure to use a back up wrench when tighteningthese fittings.
3. Then turn an additional 1/4 turn to assure a goodbrass to brass seal. Leak check the joints with soapbubbles or an electronic leak detector.

SYSTEM CHARGE - R-22The ice machine head and URC condenser are shippedwith enough refrigerant charge for up to 66 feet of line setlength. The maximum line set length is 100 equivalent feetfrom the head to the condenser.
For applications longer than 66 ft. up to the maximum 100ft. Iength, additional refrigerant must be added. For unitsutilizing 1/4" L.L. and 3/8" D.L., the line size should beincreased to 3/8"L.L. and 1/2"D.L. for the entire length ofthe run. Add 21 ounces plus 1/2 oz. per foot over 66 feet.For units utilizing 3/8"L.L., add 1/2 oz. per foot over 66feet.
NOTE:(1) Recommended line sizes are same as listed in
the line set application chart. (Page 7)(2) Older models utilize R-502 refrigerant or R-12
refrigerant. Always check the unit nameplate forthe correct refrigerant type.
(3) If refrigerant is added due to extended line setlength, mark the correct total charge on the unitnameplate for future reference.
(4) When routing and installing remote lines, alwaysuse standard refrigerant piping practices.
(5) Hoshizaki recommends eliminating any excessloops in a pre-charged line set application beforemaking the unit connections. This will eliminate oiltraps and possible crimps in the excess tubing.
(6) A service loop should be included behind the unit as shown in the illustration on page 13 to allow the unit to be moved away from the wall if needed.
CRITICAL CHARGE AMOUNTThe total system charge is critical for proper operationaccording to Hoshizaki specification. Always weigh in theproper charge per the following charge chart. (Remoteunits show standard charge good for up to 66 feet.) Unitcharge information is also found on the unit Name Plate.

The original Alpine board, #2U0127-01 was installed on allKM models produced prior to Feb. 98. Models producedafter Feb 98 will have either #2U0127-01or the new “E”control board #2A0836-01. Universal Alpine board#2U0139-01 can replace a “C” or Alpine board. It has ablack jumper between relay X3 & X4. This jumper makesthis board a “C” board. Leave the jumper if there is a whitewire in the 10 pin connector. This jumper must be cut for anAlpine application (no white wire on 10 pin connector).
SWITCH CODE: 1 = ON 0 = OFF
21 11-01-02
NOTE:Service replacement boards after Feb. 98 are #2A0836-02 or sub #2A1410-02. This “E” board is designed to re-place “C”, Alpine, or original (01) “E” boards. An applicationswitch is located between relay X3 & X4. Follow the in-structions on the board label to set this switch. If the 10 pinconnector has a white wire, switch to “C” position. If not,switch to “ALP”.
BE SURE TO FOLLOW THE INSTRUCTIONS SUPPLIED WITH THE BOARD.
The “E” service replacement board is smaller than the “C”or Alpine board. It will mount in the same location on 4 ofthe 6 mounting studs. You must cut the wire ties and stretchthe wiring to install the connectors. Each connection ismarked and connects the same as the original board.
If the black jumper is cut/not cut improperly”C” board) orthe application switch (“E” board) is in the wrong position,the inlet water valve will not energize correctly or the com-pressor will operate continually when the power switch isturned OFF.
“E” Control Board Functions -
An instruction label explaining the “E” board features isincluded somewhere on the unit (usually under the toppanel or on the control box cover). A stick-on label is alsoincluded with the service replacement. If you are replacingan “E” board, place the new label over the original label asit contains instructions for the application switch. This willadvise anyone performing future service that the originalboard has been replaced and explain the application switchas outlined below.
See the information on the label or the following for theboard features. The new diagnostic features are addedwhen this board replaces a “C” or Alpine board.

“E” Control Board Functions continued:
The #2A1410-02 universal replacement board has an ap-plication switch between relays X3 & X4 that is not in-cluded on the original factory board supplied with the unit.This application switch allows this replacement board tobe used on older C and Alpine control board models. Theapplication switch has 2 positions (C & ALP). On R-404A models, this switch must be in the ALP position. If theswitch is left in the C position, the compressor contactorwill energize as soon as power is supplied to the unitwhether the power switch is ON or OFF.
There are 4 green LED’s which light in sequence through-out the unit operation. It is important to note that the greenLED’s are not numbered consecutively. LED1 is located atthe edge of the board beside the K-2 transformer connec-tion. The numbering sequence from the outside edge of theboard is 1, 4, 3, and 2.
The green LED’s are also used for a built-in output testwhich can be conducted to diagnose a bad board. Thelabel explains the output test procedure. The correct light-ing sequence for the output test is as follows. When thecontrol switch is switched ON with the output test switchS-3 ON, you will observe the following:the Red control power LED will light after 3 seconds. Thisindicates that the control transformer has correct outputvoltage. After a 5 second delay, LED2 lights. 5 secondslater LED2 goes out and LED3 lights. 5 seconds later LED3goes out and LED4 lights. 5 seconds later LED4 goes outand LED1 lights. 5 seconds later LED1 goes out and LED4lights to begin the normal sequence of operation. If theLED’s follow this sequence, the board is OK. If any otherlighting sequence occurs, the board is bad.
Once the correct sequence is determined, the output testswitch should be replaced in the OFF position.
A copy of the “E” board label is included on the next page.Review the board label thoroughly to understand the “E”board functions.

ATTENTION !THIS UNIT HAS A CONTROL PRODUCTS IMPROVED “E” CONTROLBOARD INSTALLED. HOSHIZAKI PART NUMBER 2A1410-01.The improved “E” board includes LED lights and audible alarm safeties. The red LED indicates proper control voltage and will remain on unless a controlvoltage problem occurs. At startup a 5 second delay occurs while the boardconducts an internal timer check. A short beep occurs when the powerswitch is turned “ON” or “OFF”.
The green LED’s 1~4 represent the corresponding relays and energize andsequence 5 seconds from initial startup as follows:
Sequence Step LED’s on: Length:Min. Max. Avg. 1 Minute Fill Cycle LED 4 60 sec. Harvest Cycle LED 1, 4, & 2 2 min. 20 min. 3-5 min. Freeze Cycle LED 1 5 min. 60 min. 30-35 min. Reverse Pump Out LED 1, 3, & 2 10 sec. 20 sec. Factory set. {With light on, LED 1 = Comp/RFM; LED 2 = HGV; LED 3 = PM; LED 4 = WV} Note: LED’s are not numbered consecutively. They are # 1,4,3,2 from board edge.
The built in safeties shut down the unit and have alarms as follows: 1 beep every 3 sec. = High Evaporator Temperature >127° F.
Check for defrost problem (stuck HGV or relay), hot water enteringunit, stuck headmaster, or shorted thermistor.
2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes.Orange LED marked “H Timer” energizes. Check for openthermistor, HGV not opening, TXV leaking by, low charge, orinefficient compressor.
3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > Specified SettingYellow LED marked “F Timer” energizes. Check for F/S stuckclosed (up), WV leaking by, HGV leaking by, PM not pumping, TXVnot feeding properly, low charge, or inefficient comp. Dip switches 9& 10 allow for factory adjustment of this back up timer feature.
Note: 2 & 3 beep alarms represent 2 consecutive occurrences.
Additional alarms for mechanical bin switch: 4 beeps every 3 sec. = Short Circuit between the K4 connection on the
control board and the bin control. Check connections and replace wire harness if necessary.
5 beeps every 3 sec. = Open Circuit between the K4 connection on thecontrol board and the bin control. Check connections and replacewire harness if necessary.
Note: Units with mechanical bin switch installed, dip switch No.7 must be in the “ON” position. If thermostatic control is used No. 7 must be “OFF”.
To manually reset the above safeties, depress white alarm reset button with the power supply “ON”.
6 beeps every 3 sec. = Low Voltage. Control voltage < 92 Vac ±5%. The red LED will de-energize if voltage protection operates. 7 beeps every 3 sec. = High Voltage. Control voltage > 147 Vac ±5%.
The red LED will de-energize if voltage protection operates. Note: The voltage safety automatically resets when voltage is corrected.
The Output Test switch “S3” provides a relay sequence test. With powerOFF, place S3 on and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, & 4, in 5 second intervals, then normal sequence.Components will cycle during test. S3 should remain in the “OFF” position for normal operation.
The dip switches should be adjusted per the adjustment chart published in the Tech Specs book. No. 8 must remain in the “OFF” position.
24 11-01-02
Manual Reset SafetiesThe Alpine control board has one manual reset safety. It isthe 127°F high evaporator temperature safety. There is noindication that the Alpine board is off on this safety. Youwill only notice that the unit will restart in the 1 minute fillcycle when the power switch is shut OFF and Back ON.This is the only way to reset this safety. If this occurscheck for a hot gas circuit or valve problem, a headmasterstuck in bypass, hot water entering the unit, or a shortedthermistor. In case of a shorted thermistor, the unit will notrestart. You will hear a relay click after approximately 2seconds and the unit will remain off.
The “E” control board has 3 manual reset safeties. Theyare outlined in the control board function label. Thesesafeties shut the unit down and assist the service techni-cian in diagnosing the problem.The safeties include audible and visual alarms as follows:1 Beep = 127ºF (52.8ºC) high evaporator temp. safety.2 Beeps & orange LED = 2 consecutive 20 minute harvestcycles.3 Beeps & yellow LED = 2 consecutive maximum freezecycles. ( Factory setting for R-22 models is 60 minutes.)4 Beeps = Short circuit on mechanical bin control circuit.5 Beeps = Open circuit on mechanical bin control circuit.
Note: 4/5 beeps only function with dip 7 ON. To reseteither safety, press the white reset button on thecontrol board with the power ON. Next, proceed tocheck the items outlined on the function label.
The items listed on the function label represent the mostcommon reasons that the safety would function. Theremay be other remote possibilities however, the items listedshould be checked first.
VOLTAGE PROTECTIONBuilt-in voltage protection for the “E” board will automati-cally shut the unit down and beep if either a high or lowvoltage problem occurs as follows:6 Beeps = Low voltage condition.7 Beeps = High voltage condition.The unit will automatically restart when the voltage returnsto normal. If constant voltage fluctuation occurs, additionalexternal voltage protection will be required. The high andlow voltage protections are the only board alarms that willautomatically restart.

REMOTE HEAD PRESSURE CONTROLAll remote condenser units utilize a condensing pres-sure regulator (CPR/Headmaster) to maintain headpressure in low ambient conditions. The KM-2400SRB3 has a Sporland LAC-5 140psi valve mountedin the unit head.
The URC-20E has a 156 psi valve.
All other KM and Flaker remotes have a SporlandLAC-4190psi valve mounted in the condenser.REMOTE HEAD PRESSURE CONTROL CONNECTIONS
Troubleshooting a Head Master (CPR) valveThe symptoms of a bad headmaster are similar toan undercharged unit. To diagnose a bad headmas-ter, add additional refrigerant in 2 lb. increments andwatch the pressures. If the pressures begin to looknormal, the unit was undercharged. In this case,leak check the system to find the leak and use nor-mal refrigeration practices to recover, repair, evacu-ate and recharge the unit. If not, a bad headmasteris a possibility. Check to see if the valve is stuckopen by conducting temperature checks at the out-let of the headmaster. Replace the headmaster asnecessary. Use safe refrigeration practices whenremoving the valve and protect the valve from over-heating.
28 11-01-02
Liquid Line Valve -Hoshizaki KM remote cubers and some air and wa-ter cooled units include a liquid line solenoid downstream of the receiver and before to the expansionvalve. The purpose of this normally closed solenoidvalve is to isolate the high side refrigerant from theexpansion valve. The valve eliminates any liquid mi-gration through the expansion valve during the offcycle and will not allow refrigerant flow through theexpansion valve during an extended harvest.
It is important to remember that the 115volt solenoidshould be energized during the freeze cycle and de-energized during harvest.
Bypass Cooling -
R-22 refrigerant is very efficient in an ice machineapplication. The discharge temperature runs hotterand allows for a more efficient ice harvest as well asincreased refrigerant capacity. The one concernwith using R-22 in this application is compressoroperating temperatures. Hoshizaki uses bypasscooling to maintain cooler operating temperatures.KM units beginning with the KM-630 and larger in-clude some type of bypass cooling.
Bypass cooling is accomplished by using a bypasscapillary to feed liquid refrigerant from the liquid lineto the suction line. The liquid refrigerant flashes inthe suction line and provides addition cool gas tomaintain lower compressor operating temperatures.Bypass cooling can be continous or cycle depend-ing on the model. The capillary will sometimes beconnected to a bypass solenoid valve, which opensand closes as required to provide on-demand by-pass cooling. Bypass may be controlled through arelay and a bypass thermo-disc mounted on thecompressor dis-charge line. Review the unit wiringdiagram and refrigerant circuit diagram to determine

BIN CONTROLAll KM - E and prior series units use a thermostaticbin control. The capillary bulb is mounted in the icedrop zone or on a drop down bracket which extendsinto the bin cavity. The drop down bracket should besecured to the unit base and plug connection mustbe made before the unit will operate.
how the bypass operates and trouble shooting pro-cedures.
You will also find that the KM-1200S/MAE modelopens the bypass valve during a long harvest to addmore refrigerant to the harvest loop. This improvesoperation during a long harvest.
30 11-01-02
If the bin control bulb is not contacting the ice pyramid, anextension bracket may be needed. A bin control extensionbracket is included with all “S” models. Be sure to installthe extension if it is supplied. When installing, make surethe bracket points downward so that the cubes will easilyfall away from the bin control bulbs.
The bin control bulb and ABS holder assembly must bemounted on the back side of the extension bracket. Thiswill eliminate premature shutoff due to ice hanging up onthe holder. In case of stacked “S” models, both ABS hold-ers will be attached together and mounted to the back ofthe extension bracket.
F/DCM Bin Control Flaker / DCM units use a mechanical bin control. A paddlepivots on a hinge pin to operate either a micro- switch ormagnetic proximity switch. For proper operation, make surethat the paddle swings freely. The F-450MAF-C cubeletunit uses an Infrared eye control as it is designed fordispenser applications.
CAPACITORSSee wiring diagram reference chart for capacitor ratings.Check capacitors with an ohm meter for a short or opencircuit. A capacitor checker can be used to check thecapacitance however, it is a good common practice tochange a run capacator any time a PSC motor is replaced.Always check the run capacitor if a PSC motor will notstart, is running slow, or overheating.
When replacing a thermostatic bin control, check the op-eration by holding ice against the thermostatic bulb with thecontrol switch in the wash position. The pump should stopwithin 6 to 10 seconds. Adjust the control “CCW” for afaster shut down.

HOSHIZAKI KM CUBERSEQUENCE OF OPERATION
THE STEPS IN THE SEQUENCE ARE AS FOLLOWS:
NOTE: When power is supplied to the “E” Control board,a 5 second delay occurs at startup.
1. 1 Minute Fill Cycle
The unit always starts in the 1 minute fill cycle. Whenpower is applied to the unit the water valve isenergized and the fill period begins. After 1 minute theboard checks for a closed float switch. If the floatswitch is closed the harvest cycle begins. If not, theunit will not start without adequate water in the sump.This serves as a low water safety shut off. The watervalve will remain energized through additional1 minute cycles until water enters the sump and thefloat switch closes.
2. 1st Harvest Cycle
The compressor starts, hot gas valve opens, watervalve remains open and harvest begins. As theevaporator warms, the thermistor located on thesuction line checks for a 48° F. temperature. When48° F. is reached, the harvest is turned over to theadjustable control board defrost timer which isfactory set for normal conditions. This adjustment canvary the defrost timer from 1 to 3 minutes.
3. Freeze Cycle
After the timer terminates the harvest cycle, thehot gas and water valves close, and the iceproduction cycle starts. For the first 5 minutes thecontroller board will not accept a signal from the floatswitch. This 5 minute minimum freeze acts as ashort cycle protection. At the end of 5 minutesthe float switch assumes control. As ice builds on theevaporator the water level in the sump lowers. Thefreeze continues until the float switch opens andterminates ice production.
32 11-01-02
4. Harvest Pump Out
When the float switch opens and signals thecompletion of the freeze cycle, the harvest cyclebegins. The hot gas valve opens and the compressorcontinues to run. The drain timer starts counting the10/20 second pump out.
The water pump stops for 2 seconds and reverses,taking water from the bottom of the sump and forcingpressure against the check valve seat allowing waterto go through the check valve and down the drain. Atthe same time water flows through the small tube topower flush the float switch. When the draintimer stops counting, the pump out is complete.
Pump out always occurs on the 2nd harvest afterstartup. The Alpine control board allows foradjustment for pump out to occur every cycle, orevery 2nd, 5th or 10th cycle from this point.
5. Normal Harvest Cycle
The water valve opens to allow water to assist theharvest. As the evaporator warms, the thermistorreaches 48° F. The control board receives thethermistor signal and starts the defrost timer. Thewater valve is open during harvest (defrost) for amaximum of 6 minutes or the length of harvest,whichever is shorter. When the defrost timercompletes its count down, the defrost cycle iscomplete and the next freeze cycle starts.
The unit continues to cycle through 3, 4 and 5sequence until the bin control senses ice and shutsthe unit down.

KM CHECK OUT PROCEDURE
The following is a detailed explanation of the KM 10Minute Check Out procedure.
The 10 minute check out procedure is basically asequence check which can be used at unit startup or forsystem diagnosis. Using this check out procedure willallow you to diagnose electrical system and componentfailures in approximately 10 minutes under normaloperating conditions of 70°F or warmer air and 50°F orwarmer water temperatures. Before conducting a 10minute checkout, check for correct installation, propervoltage per unit nameplate and adequate water supply.As you go through the procedure, check to assure thecomponents energize and de-energize correctly. If not,those components and controls are suspect.
10 MINUTE CHECK OUT PROCEDURE1. Turn power OFF - gain access to unit control box.2. Turn power ON – place control switch in ice position.Note: A 5 second delay occurs for units with “E” controlboard.
A) 1 Minute Fill Cycle begins – WV energized.After 1 minute, control board checks FS. If FS isclosed…unit cycles to Harvest. Continue to (B).If FS is open, unit repeats 1 minute fill cycle untilwater enters and FS closes (low water safetyprotection during initial start up and at the end ofeach harvest)
Diagnosis: If WV does not open, check for no supplyvoltage at WV terminals, bad coil, or plugged screenor external filter (no water flow). If unit fails to startharvest, check for open FS or bad 1 minute timer inboard.B) Initial Harvest Cycle – WV remains energized,
CC energizes to start C, HGV, & (FM on RSmodel) energize. Evaporator warms…thermistorsenses 48°F…turns operation of harvest tocontrol board defrost completion timer. Timercompletes counting (1 ~3 minutes)…Unit cyclesto freeze.
Diagnosis: Check if C is running, HGV is open, WVstill open. Avg. harvest cycle at factory setting is 2~ 3 minutes. How long does initial harvest last? 1.5minutes after initial harvest begins, touch Cdischarge line. Is it hot? If not check refrigerantpressures and C operation. If it is hot, touch inletline to the evaporator. Is it hot? If it is hot and unit isnot starting freeze cycle, check defrost

completion timer adjustment, thermistor for opencircuit, discharge line temperature, C efficiency,and if HGV is fully open.
C) Freeze cycle – C remains energized, PM, (LVon RS model), and FM energize…WV & HGVde-energize. Unit is held in freeze by 5 minuteshort cycle protection timer. After 5 minutesfreeze cycle operation to transferred to FS forfreeze termination. During first 5 minutes offreeze, confirm that evaporator temperaturedrops. After 7 minutes in freeze, remove blackFS lead from K5 connector…Unit shouldimmediately switch to pump out cycle.
Diagnosis: If evaporator is not cold, check for HGVstill open, TXV not opening properly, WVcontinuing to fill reservoir, improper unit pressures, and inoperative C. If unit remains in freezewith FS removed replace board. * Normal freezecycle will last 20 ~ 40 minutes depending onmodel and conditions. Cycle times andpressures should follow performance dataprovided in Tech –Specs.
D) Pump Out Cycle – (10/20 second pump out)C remains energized, HGV energizes, FM de-energizes, PM stops for 2 seconds and starts inreverse rotation for 10/20 seconds.( Thisremoves contaminants from the water reservoirthrough check valve and down the drain andallows for power flush of FS.) Check cleartubing at check valve housing or unit drain forwater flow.
Diagnosis: If PM does not reverse, check PM circuitand capacitor. If water does not pump out,remove housing and check/clean valveassembly.
E) Normal Harvest Cycle –same as Initial HarvestCycle – Return to B)…* Unit continues to cyclethrough B)…C)…& D) (Setting can be adjustedto skip D until every 2, 5, of 10 cycles)…until bincontrol is satisfied or power is switched OFF.• Unit always restarts at A).

RESERVOIR FLUSH SYSTEMA displacement device ( cap or assembly ) is positionedover the top of the overflow stand pipe. This deviceallows sediment to be pulled from the bottom of thereservoir and flush down the drain when overflowoccurs. Water should always overflow the stand pipefor a short period towards the end of harvest to allow thisflushing action. To extend this flushing action adjust dipswitches 1 & 2 for longer harvest. If overflow does notoccur, you have restricted water flow into the unit.Check the inlet water valve screen, incoming water linesize, or the external filter system.
The displacement device must be in position for properoperation. If not, water goes down the drain during freezeand short cycling occurs.
PUMP-OUT CHECK VALVEA mechanical spring & seat check valve is located inthe pump-out housing. If this check valve sticks open,water flows down the drain during freeze and a 5 minutefreeze cycle occurs. In this case, check for a displacedseat, trash or a weak spring. Replace the spring if it isweak. When reinstalling the check valve, the seat alwaysfaces the pump supply.
KML PUMP OUTThe Standard KM series has a dual winding pump motorthat reverses direction during the pump-out cycle. Thereverse rotation pumps sediment down the drain. The KMLmodels have a single winding pump motor that does notreverse. Instead of a pump-out check valve and reversingpump, a drain solenoid and the pump motor are energizedby a relay so that sediment is pumped out.
KM CONTROL SWITCHThe standard KM models have a three position controlswitch. The switch positions are “ICE-OFF-WASH”. Also,a manual cleaning valve includes a micro-switch whichopens the control transformer circuit to the control boardduring the cleaning process. This cleaning valve must be inthe horizontal position to make ice.
The KML models have 2 switches. The control switch po-sitions are “ICE- OFF-SERVICE”. With the control switch inthe SERVICE position, the SERVICE switch is energized.
37 11-01-02
The service switch also has three positions, “DRAIN-CIRCULATE-WASH”. With the control switch in SERVICEand the service switch in DRAIN, the pump strarts anddrain valve solenoid opens to automatically drain thereservoir. In circulate, the pump motor circulates cleaner tothe outside of the evaporator. In WASH, the cleaningsolenoid energizes and the pump circulates cleaner to theinside and outside of the evaporator.
COMPONENT CHECKS:1. Float Switch: Check out the float switch with an ohmmeter. When the float is up, the switch is closed.
The symptoms of a sticking float are:Up/Closed: 60 minute freeze cycle, larger cubes,and pump cavities prior to harvest.Down/Open: Unit shuts down on low water
safety and water runs continuously.
Note: Units using “E” board will shut down on 3 beepsafety after 2 consecutive 60 minute freeze cycles.
2. Thermistor: Check out the thermistor mounting andcheck resistance versus temperature per this chart: THERMISTOR TEMPERATURE / RESISTANCE
SENSOR TEMP (F°) RESISTANCE (K OHMS)0 14.4
10 10.632 6.050 3.970 2.590 1.6
The symptoms of a bad thermistor are:Open: 20 minute harvest cycle
Note: Units using “E” board will shut down on 2 beepsafety after 2 consecutive 20 minute harvest cycles.
Shorted: Unit locks out on manual reset hightemperature safety.
Note: If evaporator reaches 127°F the thermistor signal(500 ohms) shuts down the unit on this manual reset. For“E” control boards, a 1 beep alarm will occur. To reset thisalarm, press the white reset button on the board with powerON. Then check the items listed on the control board labelfor a 1 beep alarm.
38 11-01-02
Note: The Thermistor must be mounted using a heatsink compound to assure good heat transfer and ac-curate sensing. Use Hoshizaki: Part Number 4AO683-01 or equivalent. (Radio Shack #276-1372 or GE Elec-tronics #10-8108, ect.)
3. The control board operates on 12VAC which is supplied by the control voltage transformer located in the control box. The secondary of this trans- former is connected to the K2 connector on the control board. An interlock switch is in series with the secondary winding and is operated by the cleaning valve handle mounted on the side of the evaporator compartment. If this switch is not closed, no control voltage is supplied to K-2 and the control board will not operate. This switch eliminates the possibility of the compressor operating during the cleaning process.
4. The bin control used on all KM units is an adjust-able, thermostatic control. The thermostatic bulb is
mounted in the ice drop area. To adjust the bin con trol, hold ice against the bulb while the unit is oper ating. The unit should shut off within 6 to 10 sec onds. If this does not occur, adjust the thermostatic control by turning the screwdriver slot. Adjusting towards warmer will allow the unit to shut down quicker. This djustment should be checked at instal- lation, when diagnosing a bin control problem, or if a replacement bin control is installed.
KM 150 / 250 / 280 / 500 / 630 /900 units have a bincontrol mounted in the ice drop zone. KM-1300M / Sand larger units have a drop down bracket thatmust be dropped down, secured, and plugged in atinstallation. The ice must contact the bulb tooperate the bin control. Some bin applicationsrequire an extension bracket or relocation of thebulb mounting to allow for proper shut down. Checkthis positioning if the control is adjusted properlyand ice continues to back up into the evaporatorsection. Assure that the extension bracket is in-stalled if included in the accessory bag. (See draw-ing for proper installation of extention bracker un-der BIN CONTROL section.)
39 11-01-02
The symptoms of a bad thermostatic control are:Stuck closed: The unit continues to operate when the binis full. This allows ice to back up in the evaporator com-partment and generally causes a freeze-up condition. Thiswill also occur if the bin control is adjusted too cold or fully“CW” which is the continious position. Check the adjust-ment and bulb location before you diagnose a stuck bincontrol.Stuck open : The unit will not start in the ice position. Aneasy method to check for an open bin control is to place thecontrol switch to WASH. If the pump starts, the bin controlis closed.
F/DCM bin controls may be a mechanical flapper with amagnetic proximity switch or a micro-switch assembly.Since these controls have moving parts, make sure that allparts move freely. Sticking can occur if scale builds up atthe pivot points. All flakers “E” and prior model flakers usethe mechanical proximity switch control. If the bin controlfails, the spout will fill with ice causing higher gear motorcurrent and the gear motor protect will trip or fuse willblow.5. To check the KM control board, check for 12VAC atconnector K-2. If control voltage is present, check for115VAC from pin 10 on the K-1 connector to a white neu-tral wire. Checking from pin to case can give a false read-ing in 3-phase models which have a transformer to provide115VAC for the 115V componants. If voltage is present,conduct the output test as outlined on the board functionlabel. The output test will show that the board issequenceing properly. If the output test results in an im-proper lighting sequence, replace the board. Conduct athorough 10 minute check out procedure to pinpoint theproblem area. See (10 MINUTE CHECK OUT).
Even though the output test result is correct, the outputvoltage could be bad. An additional check should be madeto check for proper output to each individual componant.Follow the wiring color code on the wiring diagram to checkthe output voltage at the K-1 connector to each componantas the unit cycles through the 10 minute check. If voltage isnot supplied to a componant when it should be or incorrectvoltage is present, the board relay contacts are likely badand the board should be replaced.
6. Check other components using a good quality multi-meterand normal electrical diagnostic procedures.

Diagnosing water problems.
Many common water related problems will causecubesto look unnatural. Looking at the ice in the bin will pointyou towards the problem area. Study these shapes andcauses to help you diagnose water related problems.
1.Normal cube No problem.Average cube size 1/2” thick x1 1/8” wide x 1 1/2” high.
2.Larger than normal cube with heavysaddled edges.Note: Normal cube may have slight saddled edge. If the float switch sticks in the up position, (closed ) the unit will have a consistent 60 minute freeze cycle. This will result in heavy saddled edges and may cause pump cavitation and ice to stick on the evaporator or icepossible bridging.
A FREEZE UP MAY OCCUR IF ICE STICKS DUE TOTHE LARGER EDGES.
41 11-01-02
3.Bridging or ice stripsa) Bridging that occurs on all ribs of all evaporator plates
is the result of excessive water in the reservoir. This iscaused by the inlet water valve leaking by. Check fora plugged bleed port in the water valve diaphragm or adefective water valve.
b) May be the result of # 2.c) Bridging can occur on a few ribs if some of the holes in
the water distribution tubes are plugged. An inspectionof the ice build up on the evaporator will show someribs with no ice and others with strips. Clean the water
distribution system.d) Bridging on 1 or 2 plates of a multiple evaporator unit
can result from water distribution problems or a refrigeration system problem. Eliminate water
problems first then check TXV, hot gas valve, charge,etc....
BRIDGING WILL GENERALLY CAUSE A FREEZE UP.
42 11-01-02
4.
Melt away of back of cubea) This can occur if the evaporator plate is scaled
up. De-scaling is required. b) Insufficient water flow during harvest can also
cause the flat side of the cube to melt away. Checkfor a plugged inlet water valve screen, pluggedexternal filter, low water pressure, or a small waterline size.
EITHER OR BOTH OF THESE ITEMS CAN CAUSETHIS SYMPTOM.
5.
Small cube
a) Can be caused by a low volume of water at thebeginning of freeze. Check for adequate water flowduring harvest. See item 4 b)
b) If the pump out check valve is stuck open or has aweak spring, the water left in the reservoir will bepumped out during the first five minutes of freeze.This results in a short cycle and slivers of ice orsmall cubes.
c) Any loss of water, whether by leak, water trail, orloose stand pipe can cause this problem.
6. Freeze ups can be caused by 2, 3, or 4 above inany combination. The major cause however is adirty (scaled up ) water system or evaporator. Athorough cleaning will eliminate most freeze ups.The second most common reason for freeze up islow water flow. Always check the evaporator, andwater flow first, then go to other checks whendiagnosing freeze ups.
(Size will depend on how much water isin the reservoir.)

CLEANING/SANITIZING PROCEDURE
A label which details the step by step cleaning/sanitizingprocedure is located on the inside front panel of the icemachine. These instructions are also provided in theInstruction Manual shipped with each unit. Follow theseinstructions to conduct a thorough cleaning andsanitizing of the water system.
Annual cleanings are recommended. More frequentcleanings may be required in bad water areas.
INLET WATER VALVE
The inlet water valve includes an 80 mesh screen toprotect the water system from debris. Always check andclear this screen during the cleaning procedure.
CLEANERS-
Hoshizaki recommends "Hoshizaki Scale Away' or"Lime-A-Way" (by Economics Laboratory, Inc.) howeverany FDA approved ice machine cleaner is acceptable. Ifyou carry a nickel safe cleaner, the acidic solution isweaker than normal cleaners to protect plated surfaces.You may need to use a heavier mixture of nickel safe tocut heavier scale deposits.

KM PRODUCTION CHECK
The steps for a cuber production check are as follows:
1. Time a complete cycle from the beginning of onefreeze cycle to the beginning of the next freezecycle.
2. Catch all of the ice from this freeze cycle andweigh the total batch.
3. Divide the total minutes in a 24 hour day (1440minutes) by the complete cycle time in minutes toobtain the number of cycles per day.
4. Multiply the number of cycles per day by the cyclebatch weight for the cuber production per 24hours.
(1440 • Total Cycle Time) x Ice Batch Weight=24 Hour Production
Once you calculate the production, check the incomingwater temperature, and ambient condensing temperatureat the cuber and cross reference to performance dataincluded in this manual to see if the calculation falls within10% of the specification.
For the most accurate production check, a normalfreeze cycle should be checked. If the evaporatorcompartment has been opened for service or if the unithas been cut off for a long period of time, the first freezecycle will be longer than normal. Timing this cycle canresult in an inaccurate production check. To avoid this,start the unit and allow it to operate for 10 minutes in thefreeze cycle, unplug the float switch lead and cause theunit to cycle into harvest mode. Replug the float switchand start timing as soon as the next freeze begins. Alsoremember that the evaporator compartment must beclosed during the production check. Removing the frontcover to check the ice buildup during a production checkwill allow heat into the evaporator and will affect the totalcycle time and actual production.

FLAKER/DCM
INSTALLATION - GENERAL
Three things are critical for a proper F/DCM installation:
1. The water temperature should fall within the 45° Fto 90° F range.
Colder water can cause excess stress on theauger gear motor which may activate the gearmotor overload.
2. A filter system is very important in poor waterquality areas as high mineral content can causepremature bearing wear.
3. The unit should be level, front to back, side toside to assure proper evaporator water level andmaximum production.
CUBELET MODELS
The DCM product produces Cubelet ice. Certain flakermodels can also be converted to produce cubelet ice.This requires changing the extruding head and cutter atthe top of the evaporator assembly. The F-650M, F-1000M, and F-2000M models are produced as cubeletmodels and are designated by a - C at the end of themodel number.
Converting a flaker to a cubelet maker reduces theoverall production by around 8 %. The flaker gear motoris sized to handle the extra load of producing cubelet icewith only a slight increase in the running amperage. Theevaporator outlet temperature and operating pressureswill be similar to the standard flaker model. Use thetemperature and pressure information provided on thestandard flaker performance data provided as a benchmark when diagnosing a converted cubelet (- C) unit.

COMPONENT TECHNICAL DATA
GEAR MOTOR SAFETIES
The auger gear motor circuit includes two overloadsafeties. The primary safety is a manual reset, currenttype protector located in the control box. This is a timedelay protector which operates at .9 amp over thenormal gear motor amp draw. The secondary safety is athermal protector which is incorporated into the gearmotor windings.
AUGER BEARINGS -Bearing Type: Sleeve/AlignmentBearing Material: Poly/Carbon
The bearings are pressed into the top extruding headand lower brass housing. A repress program is availablethrough the local Hoshizaki Distributor.
BEARING INSPECTIONSAnnual bearing inspections are recommended. Morefrequent inspections may be necessary in poor waterquality areas.The steps for bearing inspections are as follows:(1 ) Gain access to the ice chute head by removing thetop panel and spout connectors as necessary.(2) Remove the thumbnuts which hold the ice chute headin place and lift it up and off of the evaporator (take careto place the O-ring in a safe location until you replace thehead.)(3) Remove the stainless steel bolt holding the cutter orbreaker in place and lift off to access the extruding headand auger shaft.(4) Replace the bolt into the auger shaft and use it topush the auger back and forth from left to right to checkfor excessive movement.(5) Pull the auger towards you and try to insert a .02”round stock or pin gauge in between the back side of theauger shaft and bearing surface. Check severallocations around the auger shaft. If the gauge will go inbetween the shaft and bearing, it is time to install newbearings. Both top and bottom bearings should bereplaced if the top bearing is worn. If there is noexcessive movement in the auger shaft and the gaugedoes not fit, the bearings are okay. Replace the cutter, O-ring, ice chute head and connectors.
98 11-01-02
AUGER INSPECTION / BEARINGREPLACEMENT
A visual inspection of the auger bearing shaft surface isalso recommended annually in poor water areas. The stepsfor this inspection is as follows:
Note: Clean the evaporator prior to removing the auger.This will loosen scale around the extruding headand allow for easier removal.
(1) Follow steps 1 through 5 of the bearing inspectionprocedure above.
(2) Remove the (metric) Allen head cap screws that se-cure the extruding head in place.
(3) Thoroughly drain the water supply system.
4) Turn the cutter up-side down, replace the bolt and usethe cutter to lift the auger out of the evaporator. If heavyscale is present the auger may be difficult to remove. In thiscase, you will find it helpful to clean the evaporator systemfollowing the instructions located on the Inside front panel,before you attempt to remove the auger.
Older DCM units have a key welded on the inside of theevaporator cylinder. The auger has a key slot cut into thespiral flite. This keyway slot must align with the evaporatorkey before you can lift out the auger. Before attempting toremove the auger, remove the extruding head and lookinside the cylinder to align the slot and key while turning theauger.
(5) With the auger removed, remove the cutter and slidethe extruding head from the top of the auger. Visually in-spect the bearing surface at the top and bottom of theauger. Also inspect the auger flight and mechanical sealfor any damage. The extruding head contains the topbearing, the bottom bearing is pressed into the brass hous-ing at the bottom of the evaporator. To remove the housing:
(6) Remove the Allen screws that secure the evaporatorto the housing.
(7) Loosen the belly band screw and lift the evaporator up
99 11-01-02
and off of the housing. Holding the evaporator up, re-tightenthe belly band. This will hold the evaporator up so that youcan remove the housing.
(8) Remove the bolts that secure the housing to the gearmotor assembly and remove the brass housing. The me-chanical seal ceramic disk and boot are pressed into thetop of the housing. Remove these parts before you ex-change the bearings. The extruding head and brass hous-ing will be exchanged for a repressed set at your localdistributor. When you replace the new parts, reverse theorder above. Use a light coat of food grade lubricant aroundthe bottom of the evaporator and on the o-ring portion ofthe housing to the seal o-ring and help keep it in place asyou lower the evaporator. Inspect the mechanical seal thor-oughly and reuse it, if it is in good shape.
Flaker Safety’s Mechanical failures in an auger style ice machine can betime consuming and expensive repairs. Hoshizaki has in-corporated several safety’s in our Flaker and DCM unitswhich add protection against this type of failure.
The following safety’s are included in all Hoshizaki F andDCM units:1. Low water safety: Designed to protect against dryoperation or possible freeze up in the evaporator due tolow water flow. This safety utilizes the dual float switchand a 90 second timer to shut down the unit when waterflow is interrupted. The unit will automatically restart whenwater flow is resumed.
2. Protect relay safety: This safety incorporates a relay inthe gear motor circuit and will not allow the refrigerationsystem to operate unless the gear motor is running. If thegear motor fails during normal operation, the protect relayshuts down the compressor to protect against evaporatorfreeze-up.
3. Gear motor circuit safety’s: The gear motor has 2additional safety’s which will operate if the gear motor issubjected to excessive load or improper voltage. A cur-rent type manual reset safety or slow blow fuse is locatedin the control box and will trip when the gear motor amper-ageexceeds normal amp draw. This acts as a primary safetyfor the gear motor. A secondary internal thermal overload
100 11-01-02
is included in the motor windings. Both will work in con-junction with the protect relay to shut the unit down.
4. Voltage protect relay: This relay will shut the unit off incase of a voltage surge and automatically restart the unitwhen the voltage is correct.
5. High pressure switch: All Hoshizaki ice machines in-clude an automatic reset high pressure safety switch toshut down the unit in case of high head pressures.
6. Fuse protection: A lamp buss-type fuse is utilized in thecontrol circuit. Smaller units like the DCM-240 and F-300have a fuse in the incoming power circuit.
7. Short cycle protection timer: A 1 minute time delay isincluded in the start-up sequence to protect against shortcycling the gear motor or compressor.
8. Compressor protection is provided either internally or bymeans of an external motor circuit protector. This is anautomatic reset thermal type circuit breaker.
9. The F-2000 has a spout safety control to shut down theunit if the bin control fails for any reason. This is a manualreset safety and will notify the technician by means of aindicator light on the control box. To reset this safety, turnthe control switch OFF and back ON. This re-sets the hold-ing relay circuit and turns off the light.
The gear motor current protector serves as a back-up forthe bin control on other models. These safety’s protect theFlaker or DCM models from internal failures.
DUAL FLOAT SWITCH
Hoshizaki float switch, part number 435490-01 can be usedas a universal replacement on any Hoshizaki Flaker or DCMmodel in the field. It now subs for all previous float switchnumbers in our parts system.
Since the float switch is mounted into the water reservoir,it is susceptible to scale build-up. The amount of scalebuild-up will depend on the local water quality. Scale on the
101 11-01-02
switch shaft can cause the floats to stick. This will effectthe unit operation. In this case, the float switch should becleaned and checked.
The float switch is held in place on the top cover by a twistlock bracket. To remove it, twist the switch flange and lift.Soak the switch assembly in ice machine cleaner. While itis not necessary to do so, some technicians remove thefloats from the shaft during cleaning. If you remove them,note that the blue float is on top. Also it is important toclearly mark the top of the floats so that they can be re-placed correctly. (See drawing below). Installing the floatsupside down will effect the timing of the float switch op-eration. Once clean, rinse and wipe the cleaner off andcheck the switch with a good quality ohm meter.
This float switch has three wires (the black wire is com-mon) and two separate switches. Check the top switchby ohming out the black and red wires. When the float is upthe switch should be closed. Check the bottom switch byohming out the black and blue wires in the same manner. Ifeither switch fails, the assembly should be replaced.

FLAKER WATER FILL SYSTEMThe reservoir in a Hoshizaki auger type ice maker feedswater by gravity flow to the evaporator cylinder. The levelof water in the reservoir is maintained by the operation ofthe dual float switch.
The dual float switch assembly is made up of two reedswitches inside of a sealed shaft. The reed switch con-tacts are operated by individual magnets attached inside ofthe two separate floats.
As ice is made and extruded from the evaporator cylinder,the water level in the reservoir drops. When the level drops,the top float opens the top switch contacts (considered alatching circuit). Opening these contacts allows the bot-tom float switch control of the water control relay in thecontrol circuit. As the water level continues to drop, thebottom float contacts open to de-energize the water con-trol relay.De-energizing the water control relay closes a circuit tosupply 24 volts to the inlet water valve solenoid. This al-lows water to fill the reservoir. It also opens a circuit to thetimer board which starts a 90 second low water safetyshutdown timer.
When the water supply is available, the reservoir refills.As the reservoir level rises, these two switches swapjobs. The bottom float is now the latching circuit and thetop float re-energizes the water control relay. This willstop the safety timer and shut off the water flow.
If no water is available, i.e. the filter is stopped up or thewater supply is turned off, the unit cycles down and thewater valve remains energized. When the water supply isrestored, the reservoir fills and the top float switch re-energizes the water control relay to automatically restartthe unit. This system provides a consistent water level inthe reservoir and an automatic reset low water safetyprotection.
Since the float switch is mounted into the water reservoir,it is susceptible to scale build-up. The amount of scalebuild-up will depend on the local water quality. Scale onthe switch shaft can cause the floats to stick. This willeffect the unit operation. In this case, the float switchshould be cleaned and checked.

FLAKER TIMER BOARDThe solid state timer board used in Hoshizaki Flakers is asimple electronic sequence timer. In order for the board tosequence, certain circuits must be closed. In order to diag-nose a bad timer board, it is necessary to check thesecircuits to assure they are operating properly. If you aretrouble-shooting a timer, the first thing you should check isthe in coming control voltage. All Hoshizaki flakers have a24 volt control transformer. The output of this transformeris protected by a 1 amp buss type fuse. Control voltagecomes in the timer on pins 1 & 2. If you do not have 24 voltsat pins 1 & 2, check the transformer and fuse.
Now check for voltage across pins 7 & 8. This could beline voltage or control voltage, depending on the model.Review the unit wiring diagram prior to checking 7 & 8 todetermine the correct voltage. If voltage is present, thetimer board has cycled up which indicates there is not aproblem in the timer board. The problem is in the gear motorrelay circuit. remember that there is a time delay from thetime you turn the unit on to the time it cycles up completely.this time will be from 1 ~ 2.5 minutes, depending on themodel of flaker.
In order for the flaker to start up, the reservoir must be fulland both float switches must be closed. This closes thecontrol circuit to pins 3 & 4. Do not confuse these pins withthe line voltage terminals marked 3 & 4 on the compressorrelay located on the board. You can check this circuit witha volt meter across the pins or by placing a jumper acrossthem. If the unit cycles up with the jumper in place, theboard is good and your problem is in the water relay con-trol circuit.
Next, you should check the bin control circuit at pins 5 & 6.Check for a closed circuit with a volt meter or place ajumper across them. If the unit cycles up with the jumperin place, the board is good and the bin control circuit is theproblem.
The last circuit check is across pins 10 & 11. These pinsconnect to the gear motor protect relay and will shut downthe unit if the gear motor fails. Check for a closed circuitwith a volt meter or place a jumper across them. If the unitcycles up with the jumper in place, the board is good andthe gear motor protect circuit is suspect.

Flaker Sequence of Operation
The Hoshizaki Flaker utilizes a solid state sequence timerboard to switch the components on and off as needed.The sequence is as follows:
With proper voltage and water supplied to the Flaker andthe flush and ice switch is in the ice position, power issupplied to the inlet water valve. The unit will not startunless the reservoir is full and both floats on the dual floatswitch are closed (in the up position). The operation isthen turned over to the bin control. If the bin control isclosed and calling for ice, the gear motor and condenserfan motor are energized. One minute later, the compressorstarts. As the refrigeration systems cools the water in theevaporator, ice will start to form within 2 to 5 minutes. Thisdepends on the inlet water temperature and ambient condi-tions. Ice production will continue until the bin control issatisfied (opens). The shut down process is very simple.On the F-450, F-800, F-1000, and F-2000 units, the entireunit shuts down within 6 seconds after the bin controlswitch opens. On the F-300 and F-500, approximately 90seconds after the bin control switch opens, the compres-sor stops, on minute later the gear motor and condenserfan motor stop. This sequence of operation is accom-plished through a series of timers within the solid statetimer board.

DCM SEQUENCE OF OPERATION
DCM sequence for the ice making unit is similar to theF450, with a delay of the compressor at start up and adelay of the gear motor at shut down.
A periodic flush is not incorporated in the DCM units.DCM-450 and 700 models have periodic agitation in thebin to eliminate ice bridging. The solid state timer boardwill start the agitation motor for .6 seconds every 2 hours.It will also start the agitation motor for .6 seconds every10 seconds of accumulated dispensing time.
FLAKER/DCM PRODUCTION CHECK
Checking the production on a F/DCM is a simple process.To check the production you will need a bucket or pan tocatch the ice and a set of scales to weigh the ice. Afterthe unit has operated for 10 to 20 minutes, catch the iceproduction for 10 full minutes. Weigh the ice to establishthe batch weight. Multiply the batch weight by 144 for thetotal production in 24 hours. Some prefer to catch the icefor 20 minutes and multiply the weight by 72 for a morerealistic production check. It is true that a longer catch ismore accurate, however, it doubles your test time andmay only show a 1 to 2% difference in production.Performing a production check is an excellent way toprove proper F/DCM operation.
FLAKER PERIODIC FLUSH
Beginning with the F-650 and larger flakers, a periodicflush cycle is included. A 12 hour timer will cycle the unitdown and open the flush valve which allows the completewater system to drain. The unit will remain off for 15minutes which allows any ice remaining in the evaporatorto melt and flush the evaporator walls and mechanicalseal out. The inlet water valve is not energized during thisflush period. The unit will automatically restart after 15minutes on the flush timer.The F-450 will flush when the bin control is open.
