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 0.5°C below the setting temp, the compressor and the outdoor fan
stop.

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

Compressor ON Temp ➲ Setting Temp+0.5°C
Compressor OFF Temp ➲ Setting Temp-0.5°C

• While in compressor running, operating with the airflow speed set by the remote control. While in compressor
not 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.

26°C ≤ Intake Air Temp ➲ 25°C
24°C ≤ Intake Intake Air Temp<26°C ➲ Intake Air Temp-1°C
18°C ≤ Intake Intake Air Temp<24°C ➲ Intake Air Temp-0.5°C
Intake Air Temp<18°C ➲ 18°C

-28-

• 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 dehumidifica­tion operation and 4-min compressor off repeat.

Compressor ON Temp. ➲ Setting Temp+0.5°C
Compressor OFF Temp. ➲ Setting Temp-0.5°C

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

■ Heating Mode Operation(H/P model)

• When the intake air temp reaches +3°…above 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.+3°C

• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C, when above 28°C , it
operates with the low or setting airflow speed. When the indoor pipe temp is between 20°C and 28°C, it oper­ates 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 33°C, when above 35°C , it
operates with the low airflow speed.

• If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, the
outdoor 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(H/P model)

• Defrost operation is controlled by timer and sensing temperature of outdoor pipe.

• The first defrost starts only when the outdoor pipe temperature falls below -6°C after 60 minutes passed from
starting of heating operation and more than 10 minutes operation of compressor.

• Defrost ends after 12 minutes passed from starting of defrost operation or after the outdoor fan operates with­in max. 2 minutes 30 seconds when the outdoor pipe temperature rises over 12°C even it before 12 minutes.

• The second defrost starts only when the outdoor pipe temperature falls below -6°C after 60 minutes passed
from ending of the first defrost and more than 10 minutes operation of compressor.

■ Cooling overload(except : LM-1963C2L/M, LM-1723C2L/M, LM-2163C2L/M, LM-1460C2L/M)

• Control indoor fan by sensing outdoor pipe temperature.

• One step down from setting fan speed if pipe temperature is oven 50°C and if below 45°C, operate on setting
temperature.

■ Heating overload(H/P models)

• Outdoor fan ON/OFF by sensing outdoor pipe temperature.

• Outdoor fan is OFF if pipe temperature is over 6.5°C and outdoor fan is ON if pipe temperature is below 0°C.

• Outdoor fan is off if any one part is heating overload condition.

-29-

-30-

■ Fuzzy Operation (C/O Model)

• According to the temperature set by Fuzzy rule, when the intake air temp is 0.5°C or more below the setting
temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.

Compressor ON Temp ➲ Setting Temp + 0.5°C
Compressor OFF Temp ➲ Setting Temp + 0.5°C

• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the
intake air temp at that time.

26°C ≤ Intake Air Temp ➲ 25°C
24°C ≤ Intake Air Temp < 26°C ➲ Intake Air Temp + 1°C
22°C ≤ Intake Air Temp < 24°C ➲ Intake Air Temp + 0.5°C
18°C ≤ Intake Air Temp < 22°C ➲ Intake Air Temp
Intake Air Temp<18°C ➲ 18°C

• When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the
Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature
automatically according to the Fuzzy rule.

• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the
temperature.

■ Fuzzy Operation (H/P Model)

• When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since
the operation off, the operation mode is selected.

• When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only
the indoor fan is operated for 15 seconds. Then an operation mode is selected according to the intake air
temp at that moment as follows.

24°C ≤ Inatake Air Temp ➲ Fuzzy Operation for Cooling
21°C ≤ Inatake Air Temp<24°C ➲ Fuzzy Operation for Dehumidification
Inatake Air Temp<21°C ➲ Fuzzy Operation for Heating

• If any of the operation modes among cooling / dehumidification / heating mode operations is carried out for 10
sec or longer before Fuzzy operation, the mode before Fuzzy operation is operated.

1) Fuzzy Operation for Cooling

• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below
the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor
is turned on.

Compressor ON Temp ➲ Setting Temp +0.5°C
Compressor OFF Temp ➲ Setting Temp + 0.5°C

• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the
intake air temp at that time.

1) Preparation of pipings

1. Cut the pipes and the cable.

• Use the accessory piping kit or the pipes pur-

chased 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 length of the

pipe.

2. Remove burrs.

• Remove burrs from cut edges of pipes.

• Turn the pipe end toward down to avoid the

metal powder entering the pipe.

Caution:

If burrs are not removed, they may cause a gas
leakage.

3. Flaring the pipes.

• Insert the flare nuts, mounted on the connection

ports of both indoor and outdoor unit, onto the
copper pipes. Some refrgerant gas may leak,
when the flare nuts are removed from the indoor
unit, as some gas is charged to prevent the
inside of the pipe from rusting.

• Fit the copper pipe end into the Bar of flare tool

about 0~0.5mm higher. (See illustration)

• Flare the pipe ends.

4. Tape the flaring portion to protect it from the
dust or damages.

• Procedure

1. Confirm that both the gas side and liquid side
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, then con­nect the manifold gauge to the service port of
the gas side valve.

- Connect the hose of the gauge with the push
pin to the service port.

4. Air purging of the charge hose.

- Open the Low-handle valve on the gauge
slightly to air purge from the hose.

5. Set the liquid side valve to the closed position.

6. Operate the air conditioner at the cooling cycle
and stop it when the gauge indicates 1kg/cm2g.

7. Immediately set the gas side valve to the closed
position.

- Do this quickly so that the gauge ends up indi­cating 1kg/cm2g.

8. Disconnect the charge set, and mount the liquid
side and gas side valve caps and the service
port nut.

- Use torque wrench to tighten the service port
nut to a torque of 1.8kg.m.(4.2kg.m/5.5kg.m)

- Be sure to check for gas leakage.

9. Apply steps from 1 to 8 to each unit (A-unit, B­unit) by the same method.

- Confirm that the gauge needle has moved
toward-76 cmHg (vacuum of 4 mmHg or less).

5. Close the Low handle of the gauge turn off the
vacuum pump, and confirm that the gauge nee­dle does not move(approximately 5 minutes
after turning off the vacuum pump).

6. Disconnect the charge hose from the vacuum
pump.

- Vacuum pump oil.
If the vacuum pump oil becomes dirty or deplet­ed,replenish as needed.

(3) Gas Charging

(After Evacuation)

• Procedure

1. Connect the gauge to the charging cylinder.

- Connect the charge hose which you disconnect­ed from the vacuum pump to the valve at the
bottom of the cylinder.

- If you are using a gas cylinder, also use a scale
and reverse the cylinder so that the system can
be 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 to
purge the air. (Be careful of the liquid refriger­ant). The procedure is the same if using a gas
cylinder.

3. Open the low handle on the gauge and charge
the system with liquid refrigerant.

- If the system can not be charged with the speci­fied amount of refrigerant, it can be charged
with a little at a time (approximately 150g each
time) while operating the air conditioner in the
cooling cycle; however, one time is not suffi­cient, wait approximately 1 minute and then
repeat the procedure(pumping down-pin).

4. Immediately disconnect the charge hose from
the gas side valve's service port.

- Stopping partway will allow the gas to be dis­charged.

- If the system has been charged with liquid
refrigerant while operating the air conditioner
turn off the air conditioner before disconnecting
the hose.

5. Mount the valve stem nuts and the service port
nut.

- Use torque wrench to tighten the service port
nut to a torque of 1.8 kg.m.(4.2kg.m/5.5kg.m.)

- Be sure to check for gas leakage.

6. Apply steps from 1 to 5 to each unit (A-unit, B­unit) by the same method.

Check valve

This is different from previous procedures.
Because you are charging with liquid refrigerant
from the gas side, absolutely do not attempt to
charge with larger amounts of liquid refrigerant
while operating the air conditioner.

Trouble analysis

1. Check temperature difference between intake and discharge air and operating current.

All amount of refrigerant leaked out.
Check refrigeration cycle.

Refrigerant leakage
Clog of refrigeration cycle
Defective compressor

Excessive amount of refrigerant

Normal

Notice:

Temperature difference between intake and discharge air depends on room air humidity. When the room air
humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower
temperature difference is larger.

2. Check temperature and pressure of refrigeration cycle.

Notice:

1. The suction pressure is usually 4.5~6.0 kg/cm2G at normal condition.

2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with
putty.
