Common Problems and Solutions
Before calling for service
If you have problems with your air conditioner, read the following information and try to solve
the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.
Air conditioner does not operate
1. Ensure that the air conditioner is plugged into a proper outlet.
2. Check the fuse or circuit breaker.
3. Check whether the voltage is unusually high or low.
Air does not feel cold enough on the cooling setting
1. Ensure that the temperature settings are correct.
2. Check to see if the air filter is clogged with dust. If so, replace the filter.
3. Ensure that the air flow from the outside is not obstructed and that there is a clearance of
over 20" between the back of the air conditioner and the wall or fence behind it.
4. Close all doors and windows and check for any source of heat in the room.
Before calling for service, please review the following list of common problems and
solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the fan on rainy days
or in highly humid conditions. This feature is designed to help remove moisture in the air
and improve cooling efficiency.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in
highly humid conditions or on rainy days. This water overflows and drips from the rear of
the unit.
• You hear the fan running while the compressor is silent. This is a normal operational
feature.

Maintenance and Service
When the air conditioner is not going to be used for a long time.
When air conditioner is not going to be
used for a long time.
When the air conditioner is to be used again.
Operate the air conditioner on Air circulation
mode (Refer to page 23) for 2 to 3 hours.
Clean the air filter and install it in the indoor
unit.
(Refer to page 26 for cleaning filters.)
• This will dry out the internal mechanisms.
Turn off the circuit breaker, and disconnect
the plug.
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
CAUTION
Turn off the circuit breaker when the air conditioner
is not going to be used for a long time.
Dirt may collect and may cause a fire.
Remove the batteries from the remote
control.
Operation Tips
Do not overcool the room.
Keep blinds or curtains
closed.
Keep the room temperature
uniform.
This is not good for the health
and wastes electricity.
Do not let direct sunshine enter
the room when the air
conditioner is in operation.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly.
Ventilate the room
occasionally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the room.
Blockages in the air filter
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once in
every two weeks.
Since windows are kept closed,
it is a good idea to open them
and ventilate the room now and
then.

C Evaluation of the performance
Operate unit for 15~20 minutes, then check the
system refrigerant charge:
1. Measure the pressure of the gas side service
valve.
2. Measure the temperature of the intake and
discharge of air.
1. Connect a low-pressure gauge mainifold hose to the
charge port on the gas side service valve.
2. Open the gas side service valve halfway and purge
the air from the manifold hose using the refrigerant
gas.
3. Close the liquid side service valve(all the way in).
4. Turn on the unit's operating switch and start the
cooling operation.
5. When the low-pressure gauge reading becomes 1
to 0.5kg/cm2G(14.2 to 7.1 P.S.I.G.), fully close the
gas side valve stem and then quickly turn off the
unit. At that time, Pump Down has been completed
and all refrigerant gas will have been collected in
the outdoor unit.
16
Soap water method
(1) Remove the caps from the 2-way and 3-way
valves.
(2) Remove the service-port cap from the 3-way
valves.
(3) To open the 2-way valve turn the valve stem
counterclockwise approximately 90°, wait for
about 2~3 sec, and close it.
(4) Apply a soap water or a liquid neutral detergent
on the indoor unit connection or outdoor unit
connections by a soft brush to check for
leakage of the connecting points of the piping.
(5) If bubbles come out, the pipes have leakage.

C Evacuation
Connect the charge hose end described in the
preceding steps to the vacuum pump to
evacuate the tubing and indoor unit.
Confirm the "Lo" knob of the manifold valve is
open. Then, run the vacuum pump.
The operation time for evacuation varies with
tubing length and capacity of the pump. The
following table shows the time required for
evacuation.

If tubing length is less
than 10m (33 ft)
10 min. or more
If tubing length is longer
than 10m (33 ft)
Outdoor unit
15 min. or more
When the desired vacuum is reached, close the
"Lo" knob of the manifold valve and stop the
vacuum pump.
D Finishing the job
With a service valve wrench, turn the valve stem
of liquid side valve counter-clockwise to fully
open the valve.
Turn the valve stem of gas side valve
counter-clockwise to fully open the valve.
Loosen the charge hose connected to the gas side
service port slightly to release the pressure, then
remove the hose.
Replace the flare nut and its bonnet on the gas side
service port and fasten the flare nut securely with an
adjustable wrench. This process is very important to
prevent leakage from the system.
Replace the valve caps at both gas and liquid side
service valves and fasten them tight.
This completes air purging with a vacuum pump.

Air purging
AIR PURGING
Air and moisture remaining in the refrigerant
system have undesirable effects as indicated
below.
Pressure in the system rises.
Operating current rises.
Cooling(or heating) efficiency drops.
Moisture in the refrigerant circuit may
freeze and block capillary tubing.
Water may lead to corrosion of parts in the
refrigeration system.
Therefore, the indoor unit and tubing between
the indoor and outdoor unit must be leak tested
and evacuated to remove any noncondensables
and moisture from the system.
2
1
Do a leak test of all joints of the tubing(both
indoor and outdoor) and both gas and liquid side
service valves.
Bubbles indicate a leak. Be sure to wipe off the
soap with a clean cloth.
After the system is found to be free of leaks,
relieve the nitrogen pressure by loosening the
charge hose connector at the nitrogen cylinder.
When the system pressure is reduced to normal,
disconnect the hose from the cylinder.

A Preparation
Outdoor unit
Check that each tube(both liquid and gas
side tubes) between the indoor and
outdoor units have been properly
connected and all wiring for the test run
has been completed. Remove the service
valve caps from both the gas and the liquid
side on the outdoor unit. Note that both the
liquid and the gas side service valves on
the outdoor unit are kept closed at this
stage.
