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.

Clean the air filter and install it in the
indoor unit.

(Refer to page 25 for cleaning it.)

Check that the air inlet and outlet of
the indoor/outdoor unit are not
blocked.

connected correctly. It may be
connect to the indoor unit side.

Do not overcool the room. Keep blinds or curtains

closed.

Keep the room temperature

uniform.

Make sure that the doors

and windows are shut tight.

Clean the air filter

regularly.

Ventilate the room

occasionally.

This is not good for the health
and wastes electricity.

the room when the air
conditioner is in operation.

Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.

Avoid opening doors and
windows as much as possible to
keep the cool air in the room.

Blockages in the air filter reduce
the airflow and lower cooling and
dehumidifying effects. Clean at
least once every two weeks.

Since windows are kept closed,

it is a good idea to open them

and ventilate the room now and

then.

Turn off the breaker.

CAUTION:

Turn off the breaker
when the air conditioner is not going
to be used for a long time.

Case Explanation See page

• Have you made a mistake in timer operation?

• 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.

• Are the indoor unit's air inlet or outlet vents
obstructed?

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
