2) H/P ModelOperation Indicator

ON while in appliance operation, OFF while in appliance pause. Flashing while in disconnection or short in Thermistor. (3 sec off / 0.5 sec on)

Sleep Timer Indicator ON while in sleep timer mode, OFF when sleep timer cancel or appliance operation pause.

Timer Indicator ON while in timer mode (on/off), OFF when timer mode is completed or canceled.

Defrost Indicator OFF except when hot start during heating mode operation or while in defrost control.

Cooling Mode Operation When the intake air temperature reaches 0.5C below the setting temp, the compressor and the outdoor fan

stop. When it reaches 0.5C above the setting temp, they start to operate again.

Compressor ON Temp Setting Temp+0.5CCompressor OFF Temp Setting Temp-0.5C

While in compressor running, operating with the airflow speed set by the remote control. While in compressornot running, operating with the low airflow speed regardless of the setting.

Healthy Dehumidification Mode When the dehumidification operation input by the remote control is received, the intake air temperature is

detected and the setting temp is automatically set according to the intake air temperature.26C Intake Air Temp 25C24C Intake Intake Air Temp

While in compressor off, the indoor fan repeats low airflow speed and pause. While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidifica-

tion operation and 4-min compressor off repeat.Compressor ON Temp. Setting Temp+0.5CCompressor OFF Temp. Setting Temp-0.5C

In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.

Heating Mode Operation When the intake air temp reaches +3above the setting temp, the compressor is turned off. When below

the setting temp, the compressor is turned on.Compressor ON Temp. Setting Temp.Compressor OFF Temp. Setting Temp.+3C

While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20C, when above 28C , itoperates with the low or setting airflow speed. When the indoor pipe temp is between 20C and 28C, it oper-ates with Super-Low(while in sleep mode, with the medium airflow speed).

While in compressor off, the indoor fan is off when the indoor pipe temp is below 33C, when above 35C , itoperates with the low airflow speed.

If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, theoutdoor fan is turned on/off according to the indoor pipe temp.

While in defrost control, both of the indoor and outdoor fans are turned off.

Defrost Control While in heating mode operation in order to protect the evaporator pipe of the outdoor unit from freezing,

reversed to cooling cycle to defrost the evaporator pipe of the outdoor unit. After 40 min heating mode operation, at 4 min interval, whether to carry out defrost control or not and the time

of defrost control are determined according to the following conditions.1) While in heating mode operation, the maximum of the indoor pipe temperature is measured and it is com-

pared with the present indoor pipe temperature to get the difference of the indoor pipe temperatures (=themaximum temperature of indoor pipe ? the present temperature of indoor pipe), according to which, whetherto carry out defrost control or not is determined.

2) According to the need of defrost control shown above and the elapsed time of heating mode operation at thatmoment, the defrost control time is determined.

3) When the determined time of defrost control is below 7 min, heating mode operation continues without carry-ing out defrost control. According to the procedure stated above, the determination is made again. When thedefrost control time is 7 min or longer, defrost control is then carried out.

While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the presenttemp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of theindoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5C or higher, defrost con-trol is completed and heating mode operation is carried out.

While in defrost control, if the defrost time determined before the start of defrost control is completed, defrostcontrol stops and heating mode operation is carried out regardless of the above condition.

When the indoor pipe temp is 42C or above, defrost control is not carried out even if the condition is one ofthe defrost conditions above.

While in defrost control, the compressor is on and the indoor fan, the outdoor fan, and the 4 way valve are off.

Fuzzy Operation (C/O Model) According to the temperature set by Fuzzy rule, when the intake air temp is 0.5C or more below the setting

temp, the compressor is turned off. When 0.5C or more above the setting temp, the compressor is turned on.Compressor ON Temp Setting Temp + 0.5CCompressor OFF Temp Setting Temp + 0.5C

At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to theintake air temp at that time.26C Intake Air Temp 25C24C Intake Air Temp < 26C Intake Air Temp + 1C22C Intake Air Temp < 24C Intake Air Temp + 0.5C18C Intake Air Temp < 22C Intake Air TempIntake Air Temp

Off-Timer Operation When the set time is reached after the time is input by the remote control, the appliance stops operating. The timer LED is on when the off-timer is input. It is off when the time set by the timer is reached. If the appliance is on pause at the time set by the timer, the pause continues.

Off-Timer On-Timer Operation When the set time is reached after the on/off time is input by the remote control, the on/off-timer operation is

carried out according to the set time.

Sleep Timer Operation When the sleep time is reached after is input by the remote control while in appli-

ance operation, the operation of the appliance stops. While the appliance is on pause, the sleep timer mode cannot be input. While in cooling mode operation, 30 min later since the start of the sleep timer, the setting temperature

increases by 1C. After another 30 min elapse, it increases by 1C again. When the sleep timer mode is input while in cooling cycle mode, the airflow speed of the indoor fan is set to the

low. When the sleep timer mode is input while in heating cycle mode, the airflow speed of the indoor fan is set to

the medium.

Chaos Swing Mode By the Chaos Swing key input, the upper/lower vane automatically operates with the Chaos Swing or they are

fixed to the desired direction. While in Chaos Swing mode, the angles of cooling and heating cycle operations are different.

Chaos Natural Wind Mode When the Chaos Natural Wind mode is selected and then operated, the high, medium, or low speed of the air-

flow mode is operated for 2~15 sec. randomly by the Chaos Simulation.

3) How to fix installation plateThe wall you select should be strong and solid enoughto prevent vibration

1. Mount the installation plate on the wall with fourtype A screws. If mounting the unit on a concretewall, use anchor bolts. Mount the installation plate horizontally by aligning

the centerline using a level.

2. Measure the wall and mark the centerline. It isalso important to use caution concerning thelocation of the installation plate-routing of thewiring to power outlets is through the walls typi-cally. Drilling the hole through the wall for pipingconnections must be done safely.

4) Drill a hole in the wall Drill the piping hole with a 70mm hole core drill. Drill

the piping hole at either the right or the left with thehole slightly slanted to the outdoor side.

2. Flaring Work and Connection of Piping

1) Flaring workMain cause for refrigerant leakage is due to defect inthe flaring work. Carry out correct flaring work using thefollowing procedure.

1. Cut the pipes and the cable. Use the piping kit accessory or pipes purchased locally. Measure the distance between the indoor and the

outdoor unit. Cut the pipes a little longer than the measured

distance. Cut the cable 1.5m longer than the pipe length.

2. Burr removal Completely remove all burrs from the cut cross sec-

tion of pipe/tube. Put the end of the copper tube/pipe in a downward

direction as you remove burrs in order to avoid drop-ping burrs into the tubing.

3. Putting nut on Remove flare nuts attached to indoor and outdoor

unit, then put them on pipe/tube having completedburr removal.(not possible to put them on after flaring work)

4. Flaring work Firmly hold copper pipe in a die in the dimension

shown in the table above.

Carry out flaring work using flaring tool as shownbelow.

5. Check Compare the flared work with figure below. If flare is noted to be defective, cut off the flared sec-

tion and re-flare it.

1. Air purging Required tools : hexagonal wrench, adjustable

wrench, torque wrenches, wrench tohold the joints, and gas leak detec-tor.

The additional gas for air purging has been chargedin the outdoor unit.However, if the flare connections have not be donecorrectly and there gas leaks, a gas cylinder and thecharge set will be needed.

The air in the indoor unit and in the piping must bepurged. If air remains in the refrigeration pipes, it willaffect the compressor, reduce to cooling capacity, andcould lead to a malfunction.

Procedure (1) Recheck the piping connections.(2) Open the valve stem of the 2-way valve coun-

terclockwise approximately 90, wait 10 sec-onds, and then set it to closed position. Be sure to use a hexagonal wrench to operate

the valve stem.

(3) Check for gas leakage. Check the flare connections for gas leakage.

(4) Purge the air from the system. Set the 2-way valve to the open position and

remove the cap from the 3-way valves serviceport.

Using the hexagonal wrench to press the valvecore pin, discharge for three seconds and thenwait for one minute. Repeat this three times.

(5) Use torque wrench to tighten the service portnut to a torque of 1.8kg.cm.

(6) Set the 3-way valve to the back seat. (7) Mount the valve stem nuts to the 2-way and 3-

way valves. (8) Check for gas leakage.

At this time, especially check for gas leakagefrom the 2-way and 3-way valves stem nuts,and from the service port nut.

CautionIf gas leakage are discovered in step (3) above,take the following mesures : If the gas leaks stop when the piping connectionsare tightened further, continue working from step (4). If the gas leaks do not stop when the connectionsare retightened, repair the location of the leak, dis-charge all of the gas through the service port, andthen recharge with the specified amount of gasfrom a gas cylinder.

Service port nut:Be sure, using a torque wrench to tighten the service port nut (after using the service port), so that it prevents thegas leakage from the refrigeration cycle.* CAUTION : Do not leak the gas in the air during Air purging.

2. Pumping down

Procedure (1) Confirm that both the 2-way and 3-way valves

are set to the open position. Remove the valve stem caps and confirm that

the valve stems are in the raised position. Be sure to use a hexagonal wrench to operate

the valve stems.

(2) Operate the unit for 10 to 15 minutes.

(3) Stop operation and wait for 3 minutes, thenconnect the charge set to the service port ofthe 3-way valve. Connect the charge hose with the push pin to

the service port.

(4) Air purging of the charge hose. Open the low-pressure valve on the charge set

slightly to air purge from the charge hose.

(5) Set the 2-way valve to the closed position.

(6) Operate the air conditioner at the coolingcycle and stop it when the gauge indicates1kg/cm2g.

(7) Immediately set the 3-way valve to the closedposition. Do this quickly so that the gauge ends up indi-

cating 3 to 5kg/cm2g.

(8) Disconnect the charge set, and mount the 2-way and 3-way valves stem nuts and the ser-vice port nut. Use torque wrench to tighten the service port

nut to a torque of 1.8 kg.m. Be sure to check for gas leakage.

1) Re-air purging (Re-installation)

Procedure (1) Confirm that both the 2-way valve and the 3-

way valve are set to the closed position.

(2) Connect the charge set and a gas cylinder tothe service port of the 3-way valve. Leave the valve on the gas cylinder closed.

(3) Air purging. Open the valves on the gas cylinder and the

charge set. Purge the air by loosening the flarenut on the 2-way valve approximately 45 for 3seconds then closing it for 1 minute; repeat 3times.

After purging the air, use a torque wrench totighten the flare nut on the 2-way valve.

(4) Check for gas leakage. Check the flare connections for gas leakage.

(5) Discharge the refrigerant. Close the valve on the gas cylinder and dis-

charge the refrigerant until the gauge indicates3 to 5 kg/cm2g.

(6) Disconnect the charge set and the gas cylin-der, and set the 2-way and 3-way valves to theopen position. Be sure to use a hexagonal wrench to operate

the valve stems.

(7) Mount the valve stem nuts and the serviceport nut. Use torque wrench to tighten the service port

2) Balance refrigerant of the 2-way, 3-way valves (Gas leakage)

Procedure (1) Confirm that both the 2-way and 3-way valves

are set to the back seat.

(2) Connect the charge set to the 3-way valvesport. Leave the valve on the charge set closed. Connect the charge hose with the push pin to

the service port.

(3) Open the valve (Lo side) on the charge setand discharge the refrigerant until the gaugeindicates 0 kg/cm2G. If there is no air in the refrigerant cycle (the

pressure when the air conditioner is not run-ning is higher than 1 kg/cm2G), discharge therefrigerant until the gauge indicates 0.5 to 1kg/cm2G. if this is the case, it will not be neces-sary to apply a evacuatin.

Discharge the refrigerant gradually; if it is dis-charged too suddenly, the refrigeration oil willalso be discharged.

3. Evacuation (All amount of refrigerant leaked)

Procedure (1) Connect the vacuum pump to the charge sets

center hose

(2) Evacuation for approximately one hour. Confirm that the gauge needle has moved

toward -76 cmHg (vacuum of 4 mmHg or less).

(3) Close the valve (Lo side) on the charge set,turn off the vacuum pump, and confirm thatthe gauge needle does not move (approxima-tely 5 minutes after turning off the vacuumpump).

(4) Disconnect the charge hose from the vacuumpump. Vacuum pump oil.

4. Gas Charging (After Evacuation)

Procedure (1) Connect the charge hose to the charging

cylinder. Connect the charge hose which you dis-con-

nected from the vacuum pump to the valve atthe bottom of the cylinder.

If you are using a gas cylinder, also use a scaleand revers the cylinder so that the system canbe charged with liquid.

(2) Purge the air from the charge hose. Open the valve at the bottom of the cylinder

and press the check valve on the charge set topurge the air. (Be careful of the liquid refriger-ant). The procedure is the same if using a gascylinder.

(3) Open the valve (Lo side on the charge set andcharge the system with liquid refrigerant. If the system can not be charged with the spec-

ified amount of refrigerant, it can be chargedwith a little at a time (approximately 150g eachtime) while operating the air conditioner in thecooling cycle; however, one time is not suffi-cient, wait approximately 1 minute and thenrepeat the procedure (pumping down-pin).

(4) Immediately disconnect the charge hose fromthe 3-way valves service port. Stopping partway will allow the gas to be dis-

charged. If the system has been charged with liquid

refrigerant while operating the air conditionerturn off the air conditioner before disconnectingthe hose.

(5) Mount the valve stem nuts and the serviceport nut. Use torque wrench to tighten the service port


\

This is different from previous procedures.Because you are charging with liquid refrigerantfrom the gas side, absolutely do not attempt tocharge with larger amounts of liquid refrigerantwhile operating the air conditioner.
