• Anti-Tie Down Device

• Three 4.5 KW electric, immersion typeheaters and insulated tank depending onmodel.

• Steam heat

!

CONSTRUCTION FEATURESThe general arrangements of the Models LKR andLKD Liftkleen assemblies, including optionalfeatures, are shown in Figures 1 and 2. Thefollowing paragraphs describe specificconstruction details.

• TANK ASSEMBLYThe Liftkleen was designed to withstand therugged demands of heavy-duty industrial andautomotive parts cleaning. The tank is leak-tested after welding. The bottom of the tankutilizes double wall construction and issupported by four channels. Openings areprovided to facilitate moving the Liftkleen witha fork-lift truck. A 1-1/2” NPT drain is locatedin the bottom of the tank to which permanentdrain connections can be attached. Anoverflow port is part of the tank assembly andis intended for use with heated models only.A water fill port is located in the rear of thetank (see Figure 8) and consists of 3/4” NPTpipe nipple. On optional heated models, thetank sides and cover are insulated with 1”thick polystyrene foam (equal to two-plusinches of fiberglass).

• PLATFORM AND LIFTER ASSEMBLYThe Platform and Lifter Assembly aredesigned to handle loads specified for theparticular model of Liftkleen (see Table 2).The platform consists of an angle iron framewhich supports an open steel grate. The lifterassembly is made up of a channel weldment,platform support weldment, four supportrollers with needle bearings and hardenedshafts, and a pneumatic cylinder. (Airconsumption data can be found in Table 3).

The rollers and bearings on all Model LKRand LKD units are located outside the tankand therefore never immersed in the cleaningsolution. This helps keep moving partslubricated. The standard open steel grate ofthe platform assembly can be replaced withthe optional roller conveyor platform.

• PUMP ASSEMBLYThe Superflo Pumping Unit Assembly, anavailable option on all Model LKR and LKDunits, is capable of providing 10,000 gallonsper hour of flow and provides exceptionalliquid agitation for quicker, more effectiveparts cleaning. It is especially effective onparts containing holes. The pump is acentrifugal unit and is driven by an electricmotor.

• COVER ASSEMBLYThe internal cover is made of stainless steelto eliminate corrosion caused by vaporcondensation. On heated models, openingand closing the lid is accomplished manuallyutilizing a counter balanced lid (Figure 6). Anoptional pneumatically powered lid isavailable on heated units (Figure 7). Lids, aswell as tanks, are insulated on heated units.

Unheated units must be ordered with apneumatically powered lid (Figure 7). The lidactuation system on these units contains atemperature sensitive automatic closingfeature. In the event of a fire in the tank, theplatform assembly lowers and the lid closesautomatically.

WARNINGAlways stand clear of lid. To prevent injury,keep head, hands and body clear of the lid, liftplatform and lift mechanism at all times. Theseunits have moving parts, pinch-points andclose tolerances. Always stand clear of the liftplatform and lid when operating as the lidcould unexpectedly open or the platformoperate. Keep hands and fingers away fromtank when operating platform.

CAUTIONWhen turning air on or off or when operatingthe lift platform, stay clear of the lid, liftplatform and operating mechanism as the lidcould unexpectedly open or the platformoperate.

• PNEUMATIC CONTROLSThe standard Liftkleen is furnished with apneumatic system that raises and lowers theplatform, a master on/off valve and afilter/regulator/ lubricator unit.

The agitating lift platform contains aircontrols that agitate the platform up anddown through a range of five inches with avariable frequency of 20 to 40 strokes perminute. Stroke frequency depends on loadand available air pressure. Adjustments tothe system should be made under operatingload conditions.

The platform agitation system consists of acontrol box with a 2-position oscillationswitch, a start and a restart switch, a masteron/off valve, a filter/regulator/lubricator unit, apilot operated directional control valve andtwo limit valves.

!

!

The optional pneumatically opened lid controlis incorporated with the platform agitationsystem.

Schematics and operation sequence sheetsare presented in Figures 4a through 4c.

All pneumatic tubing connections are madewith Instant Fittings. These make it possibleto connect and disconnect the tubing to thefittings without the use of a wrench. Todisconnect a tube, simply push in the brassor plastic collet with a screwdriver tip and pullthe tube from the socket. To engage the tube,push it into the fitting until it hits the stop.Sealing of the connection is achieved with anO-Ring in the fitting. This procedure is shownin detail in Figure 22.

The air cylinder for raising, lowering andoscillating (agitating) the work platform haspneumatic lines connected to both its “up”and “down” ports. This provides for smooth,positive, controlled motion in both traveldirections with minimal dependence on theweight of the work load.

• ELECTRIC CONTROLSElectrical controls are required on all unitswhich have pumps, electric heat or steamheat. Models equipped with optional Superflopump assemblies come equipped with amanual motor starter and thermal overloadprotection. Electrically heated models areequipped with from one to four stainless steel4.5 KW electric, immersion-type heaters, athermostat and contactor. Refer to Table 4 forthe amperage requirements of LiftkleenElectric Heaters and Pump Motors.

Insulation is added to the tank sides and topon all heated models. This insulation consistsof one inch thick polyurethane foam.

INSTALLATION

• SERVICE HOOK-UPAIRUnits are supplied with a Lockable Air Switchconnection. Connect an air supply line to theinlet of the master on/off valve located on theside of the machine (see Figure 14). Therecommended air piping arrangement shouldbe followed to assure trouble-free operation(see Figure 15). Once your line is connected,make sure the air switch sleeve is fullyengaged to ensure proper air supply.

Note: The minimum operating air pressure is85 PSI, however, operating at this pressuregreatly reduces the lift capacity of the unit.We recommend operating the unit at 90-100PSI for optimal performance. Maximum inletpressure is 110 PSI. A pressure gauge isprovided on the filter/regulator/lubricatorwhich is located on the side of the Liftkleenwasher next to the Air Switch Connection.

ELECTRIC

• On Liftkleen models with Superflo PumpAssembly only, a junction box is providedon the side of the unit for hook-up with theappropriate electrical service.

• On Liftkleen models with electric heatonly, an electrical enclosure is provided.The attachment points on the contactor areappropriately marked.

• On Liftkleen models with both SuperfloPump Assembly and electric heat, anelectrical enclosure containing a contactoris provided. Connections on the contactorare appropriately marked.

WARNINGThe Liftkleen must be properly grounded.

CAUTIONCheck the electrical specifications on thenameplate to assure the proper connections.On 3 phase models equipped with a Superflopump, make sure that the motor rotation iscorrect; that is, counter clockwise whenviewed from the top. To reverse rotation,switch any two of the 3 phase leads.

DRAIN – A 1-1/2˝ NPT female drain islocated on the bottom of the tank assembly. Aplug is installed at the factory. To makeconnections to the drain, remove the plug

and install appropriate plumbing. It issuggested that a shut-off valve be installed.

WATER SUPPLY – A 3/4˝ NPT pipe nipple isfurnished at the rear of the Liftkleen asshown on Figure 8. This is intended as a con-nection to a water source for filling tank ormake up supply for heated Liftkleen models.

• FLOOR MOUNTING OF LIFTKLEENFour (4) mounting holes for anchoring theModels LKR and LKD Liftkleen to the floorare located in the bottom of the channelweldment assembly at the rear of themachine (see Figures 9a,b). These holesaccommodate 1/2˝ diameter bolts. Themachine must be anchored to the floor atthese points. Failure to adequately anchorthe unit will affect its lifting capacity and/orcause structural damage to the machine.

OPERATIONWARNING

Always stand clear of lid. To prevent injury,keep head, hands and body clear of the lid, liftplatform and lift mechanism at all times. Theseunits have moving parts, pinch-points andclose tolerances. Always stand clear of the liftplatform and lid when operating as the lidcould unexpectedly open or the platformoperate. Keep hands and fingers away fromtank when operating platform.

• AGITATING LIFT PLATFORMTo operate the unit, first open the lid. On unitsequipped with the pneumatically operatedlid, this is done automatically during the nextstep. Press the "RESET" button. Theplatform will rise to the top of the unit and isnow ready for loading. Please note, theplatform will not rise until the lid is fully open.

Once loaded, rotate the Oscillate SelectorSwitch to the "ON" position. Press the"START" button. Platform will descend todown position and remain there until lid isclosed. Upon lid closure, the platform willbegin to oscillate and will continue to do sountil the operator depresses the "RESET"button or rotates the Oscillate SelectorSwitch to the "OFF" position. Be sure to openlid when resetting platform. The platform willnot oscillate unless lid is closed. Those unitsequipped with a pneumatically operated lidwill close automatically. If soaking is desired,

rotate the Oscillate Selector Switch to the"OFF" position. Once the "START" button ispressed, the unit will lower and stop in thefully down position and will remain idle untilthe operator depresses the "RESET" buttonor rotates the Oscillate Selector Switch to the"ON" position.

• CYCLE TIMER (OPTIONAL)This option allows the operator to set thelength of time of the cleaning cycle. Toactuate the timer, turn the Timer SelectorSwitch to the "On" position. Set the timer tothe desired cycle time, depress the "Start"button to begin the sequence. The platformwill agitate for the preset time after which itwill rise along with the lid to an Up/Openposition for the start of the next cycle. TurnTimer Selector Switch to the "Off" positionwhen manual operation is desired.

Note: The Cycle Timer is only available onunits with automatically operated lids.(LKR & LKD units)

• EMERGENCY STOPThe unit includes an E-Stop feature which willshut down all pneumatic operation whendepressed and should be used in emergencysituations only. Once the obstruction/problemis corrected the switch can be reset by simplylifting the button back into its original position.

• ANTI-TIE DOWN DEVICE (OPTIONAL)This device protects the operator frompotential situations where contact with apinch point on the machine can occur. Thefunction of this device replaces the "START"button in the preceding sequence instructionsand will require the operator to depress twobuttons simultaneously and hold them untilthe lid is resting in the closed position. Theunit will then function normally as describedin the previous operational instructions.

• SUPERFLO PUMP (OPTIONAL)A manual starter is provided to enable theoperator to turn the pump on when pump agi-tation is desired. If the optional filtrationsystem is selected, the pump must beoperated to create the filtration process. Thegeneral arrangement of a pump assembly isshown in Figure 16. For wiring schematic,see Figure 3.

• ELECTRIC HEAT (OPTIONAL, AQUEOUSUNITS ONLY)Heaters are automatically turned on and offby the thermostat (Figure 11) to maintain thedesired tank temperature. The thermostat isadjusted by rotating the dial over its indicatedrange of 60°F to 180°F. The heaters can beshut off by setting the thermostat to the “Off”position. Figure 12 contains data regardingheat-up time for the various Liftkleen models.For wiring schematic, see Figure 3.

Operating temperature should not exceed180°F.

Note: Never operate heaters unless they arecompletely covered by liquid.

• STEAM HEAT (OPTIONAL)Liftkleens are available with optional steamheat. This option comes complete with a ther-mostat and all necessary plumbing andrequires the hook-up of the steam supply andcondensate lines along with the connection ofa 115V electrical supply to the thermostat.

• HEATER TIMER (OPTIONAL)The LKT-1 Heater Timer is available on allheated Liftkleen units. This option allows theoperator to preset both the heater startuptime and the length of time the heater is inoperation each day. The timer also features a“day skipper” feature which allows the unit toremain off on weekends, lowering heatingcosts.

• LIFTKLEEN FILTRATION SYSTEMS(OPTIONAL)Filtration systems are available on allLiftkleen models featuring pump agitation.The system consists of standard, single ordual filters and a selection of filter elements.

Model LKF-100 (Figure 20) is a singlecartridge filter. Model LKF-22 (Figure 21) is adual cartridge unit. Model LKF-100 isequipped with a 100 mesh (150 micron)Cylinder Strainer Cartridge.

MAINTENANCEWARNING

Follow all Lock Out procedures beforeperforming any service or maintenance.

LOCK OUT PROCEDURES• When performing any maintenance tasks on the

Liftkleen be sure that the master on/off air linevalve is in the “OFF” position (see Figure 14).

• Disconnect the main air supply to the rackand/or lid cylinders to remove residual airpressure.

• Also, turn electric power to machine “OFF” atmain disconnect.

LUBRICATION• Lubricate the lift channels or roller track (Figure

18) with machinery grade grease. It isrecommended that this lubrication be done atleast every month.

• Lubricate the lid hinges (Figure 18) by oilingwith light machinery oil (SAE 30W orequivalent). This should be done every month.This includes the lid hinges and the lid openingmechanism. Entire lid mechanism should beinspected for wear, especially hinges and boltattaching lift to cover.

PNEUMATIC SYSTEM• The filter/regulator/lubricator unit on the side of

unit (shown on Figure 14) must be checked atleast weekly. The moisture in the filter bowl isdrained by opening the drain valve at thebottom of the unit. This is especially importantduring hot weather and may require morefrequent attention.

The lubricator must be filled as required withSAE 10W oil or its equivalent and setapproximately at 3 drops per minute. Thepressure regulator is adjustable between 60-110 PSI. Remember, the unit’s lifting capacitychanges as the air pressure goes up and down.Recommended pressure is 90 - 100 PSI.
