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.

TEST RUNNING
1. Check that all tubing and wiring have been
properly connected.
2. Check that the gas and liquid side service
valves are fully open.
A Settlement of outdoor unit
Anchor the outdoor unit with a bolt and nut
(?10mm) tightly and horizontally on a concrete
or rigid mount.
When installing on the wall, roof or roof top, anchor
the mounting base securely with a nail or wire
assuming the influence of wind and earthquake.

conveyed to the hose, secure the unit with an
anti-vibration bushing.
Bolt
Tubing connection
B 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.
3. Ensure the difference between the intake
temperature and the discharge is more than
8?C(46?F) (Cooling) or (Heating).
NOTE: If the actual pressure is higher than
shown, the system is most likely over-charged,
and charge should be removed. If the actual
pressure are lower than shown, the system is
most likely undercharged, and charge should
be added.
The air conditioner is now ready for use.
PUMP DOWN
This is performed when the unit is to be
relocated or the refrigerant circuit is
serviced.
Pump Down means collecting all refrigerant in
the outdoor unit without loss in refrigerant gas.
CAUTION:
Be sure to perform Pump Down procedure
with the unit cooling mode.
Pump Down Procedure
1. Connect a low-pressure gauge manifold
hose to the charge port on the gas side
service valve.
2. Open the gas side service valve half way
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/cm2 G(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.

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.

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.
The air conditioner is now ready to test run.

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.
Air purging with vacuum
pump
Do a leak test of all joints of the tubing(both
indoor unit and outdoor unit) 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.
Indoor unit
Outdoor unit
A Preparation
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.
B Leak test
Manifold valve
Pressure
gauge
Connect the manifold valve(with pressure
gauges) and dry nitrogen gas cylinder to
this service port with charge hoses.
Charge hose
Be sure to use a manifold valve for air
purging. If it is not available, use a stop valve
for this purpose. The "Hi" knob of the manifold
valve must always be kept close.
Pressurize the system to no more than 150
P.S.I.G. with dry nitrogen gas and close the
cylinder valve when the gauge reading
reached 150 P.S.I.G. Next, test for leaks with
liquid soap.
Nitrogen gas
cylinder(in vertical
standing position)
To avoid nitrogen entering the refrigerant
system in a liquid state, the top of the cylinder
must be higher than its bottom when you
pressurize the system. Usually, the cylinder is
used in a vertical standing position.

If an awning is built over the unit to
prevent direct sunlight or rain exposure,
make sure that heat radiation from the
condenser is not restricted.
Ensure that the space around the back
and sides is more than 300mm. The front
of the unit should have more than 700mm
of space.
Do not place animals and plants in the
path of the warm air.
Take the air conditioner weight into
account and select a place where noise
and vibration are minimum.
Select a place so that the warm air
and noise from the air conditioner do
not disturb neighbors.
