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

7. Immediately set the gas side valve to the closed
position.
- Do this quickly so that the gauge ends up indicating 1kg/
g.
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.
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.

• 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.
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.
- 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.

Normal
Notice:
Temperature difference between intake and discharge air depends on room air humidity. When the room air
humidity is relatively 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.

2. The product is not operate with the remote controller.
Turn on Main Power
While the compressor has been stopped, the compressor does not
operate owing to the delaying function for 3 minutes after stopped.
When the compressor stopped Indoor Fan is driven by a low speed.
At this point the wind speed is not controlled by the remote controller.
(When operated in the Sleeping Mode, the wind speed is set to the
low speed by force.)

Check the contact of CN-DISP1 connector.
When the detect switch(double key) inside the remote
controller door is fault, it is impossible to operate

3. When cooling does not operate
Turn on Main Power
Operate "Cooling Mode( )" by setting the desired temperature of the
remote controller is less than one of the indoor temperature by 1°C at least.
When in Air Circulation Mode, Compressor/Outdoor Fan is stopped.
Check the sensor for indoor temperature is attached as close as to be
effected by the temperature of Heat Exchanger(EVA).
When the sensor circuit for indoor temperature and connector are in bad
connection or are not engaged, Compressor/Outdoor Fan is stopped.
• Check the indoor temperature sensor is disconnected or not(About 10kΩ / at 25°C).
Check Relay(RY - COMP) for driving compressor.
• When the power(About AC220V/240V) is applied to the connecting wire
terminal support transferred to compressor, PWB Ass'y is normal.
• Check the circuit related to the relay.
