Helpful information
CAUTION
CAUTION
The air filters and your electiric bill.
If the air filters become clogged with dust, the
cooling capacity will drop, and 6% of the
electricity used to operate the air conditioner will
be wasted.
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.
Operation Tips
Do not overcool the room.
This is not good for the health
and wastes electricity.
Clean the air filter regularly.
Blockages in the air filter
reduce the airflow and lower
cooling and dehumidifying
effects. Clean at least once
every two weeks.
Keep blinds or curtains
closed.
Make sure that the doors
and windows are shut tight.
Do not let direct sunshine
enter the room when the air
conditioner is in operation.
Avoid opening doors and
windows as much as possible
to keep the cool air in the
room.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.

Troubleshooting
Tips
Before you call for service...
Troubleshooting Tips! Save time and money!
Check the following points before requesting repairs or service.... If the malfunction persist, please contact your
dealer.
Case
The air conditioner does not
operate.
The room has a peculiar odor.
It seems that condensate is
leaking from the air Conditioner.
Air conditioner does not operate
for about 3 minutes when restart.
Does not cool or heat effectively.
The air conditioner operation is
noisy.
Crack sound is heard.
Remote control display is faint, or
no display at all.
Explanation
Have you made a mistake in timer operation?
On first starting, the indoor unit operates in
fifteen seconds.
l Has the fuse blown or has the circuit breaker
been tripped?
l Check power supply for single/reverse phase,
voltage imbalance.
l Check that this is not a damp smell exuded by
the walls, carpet, furniture or cloth items in the
room.
l Condensation occurs when the airflow from the
air conditioner cools the warm room air.
l This is the protector of the mechanism.
l Wait about three minutes and operation will
begin.
l Is the air filter dirty? See air filter cleaning
instructions.
l The room may have been very hot when the
room air conditioner was first turned on. Allow
time for it to cool down.
l Has the setting temperature been set
incorrectly?
l Are the indoor unit's air inlet or outlet vents
obstructed?
l For a noise that sounds like water flowing.
-This is the sound of freon flowing inside the air
conditioner unit.
l For a noise that sounds like the compressed air
releasing into atmosphere.
-This is the sound of the dehumidifying water
being processed inside the air conditioning
unit.
l This sound is generated by the
expansion/contraction of the inlet grille, etc. due
to changes of temperature.
l Has the circuit breaker been tripped?

5. Checking the Drainage
1) Checking the Drainage
1. Remove the Air Filter.
2. Check the drainage.
• Spray one or two glasses of water upon
the evaporator.
• Ensure that water flows drain hose of
indoor unit without any leakage.

6) Pipe bending
ENGLISH
Annealed copper pipe with small diameter (ø6.35 or ø9.52) can be easily bent manually. In
this case, secure large R(radius) for the bend section and gradually bend pipe. If annealed
copper pipe is large in diameter (ø12.7, ø15.88 or ø19.05), bend pipe with bender. Use bender
appropriate for the pipe diameter.
7) Brazing
In refrigerant piping, bending (in particular, acute bending) must be minimized to reduce
piping resistance. Bending is, however, necessary in some places by virtue of the installation
position of devices or of the building structure, piping distance or finishing appearance.
Perform brazing using ready-made elbow. Aside from this function, brazing
perform brazing using ready-made elbow. Aside from this function, brazing
also serves to connect straight pipes, generally using ready-made sockets. While brazing,
protect piping against heat with wet cloth to avoid damaging valve packing or burning
thermal insulator with burner heat. While brazing, blow inert gas (nitrogen gas or carbonic
gas) to prevent formation of oxidation film in copper piping; otherwise, the refrigerant circuit
will clog. The blowing of nitrogen gas (or carbonic gas) through 3-way valves is described in
the following:
8) Refrigerant piping(Flare piping)
When connecting piping, be sure to keep piping dry(keep piping away from water), clean
(keep piping away from dust) and airtight (avoid refrigerant leakage).
When connecting piping on rainy days or making a through-hole in wall, take due care to
prevent water or plaster from entering piping.
Water enters
Plaster enters
CAUTION
a. This procedure is designed to prevent formation of oxidation film by filling piping with
inert gas. Note that excessive gas pressure will generate pinholes at brazed points.
(Nitrogen gas: Supply pressure
0.05~0.1kg/cm2G)
b. When supplying inert gas, be sure to open one end of piping.

3. Connecting Pipes to the Indoor Unit
3-1. Preparation of Piping
Main cause of gas leakage is defect in
