Outdoor Unit
The heat exchanger coils and panel vents of the
outdoor unit should be checked regularly. If clogged
with dirt or soot, the heat exchanger and panel vents
may be professionally steam cleaned.
Note:
Dirty or clogged coils will reduce the operating
efficiency of the system and cause higher
operating costs.
12
When the air conditioner is to
be used again.
When it is not going to be used for
a long time.
1
Operate the air conditioner on Air circulation
mode for 2 to 3 hours.

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.

Explanation
¥ Have you made a mistake in timer operation?
¥ On first starting, the indoor unit operates in
fifteen seconds.
¥ Has the fuse blown or has the circuit breaker
been tripped?
¥ Check that this is not a damp smell exuded by
the walls, carpet, furniture or cloth items in the
room.
¥ Condensation occurs when the airflow from the
air conditioner cools the warm room air.
¥ This is the protector of the mechanism.
¥ Wait about three minutes and operation will
begin.
¥ Is the air filter dirty? See air filter cleaning
instructions.
¥ The room may have been very hot when the
room air conditioner was first turned on. Allow
time for it to cool down.
¥ Has the setting temperature been set
incorrectly?
¥ Are the indoor unit's air inlet or outlet vents
obstructed?
¥ For a noise that sounds like water flowing.
-This is the sound of freon flowing inside the air
conditioner unit.
¥ 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.
¥ This sound is generated by the
expansion/contraction of the inlet grille, etc. due
to changes of temperature.
¥ Has the circuit breaker been tripped?
