Operation Tips

Helpful information

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.

When it is not going to be used for 
a long time.

When the air conditioner is to be used again.

Operate the air conditioner at the
following settings for 2 to 3 hours.

• Type of operation: Fan operation mode.
• This will dry out the internal mechanisms.

Turn off the breaker. 

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

Dirt may collect and may cause a fire.

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

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

Check that the ground wire is
connected correctly. It may be connect
to the indoor unit side.

Do not overcool the room.

This is not good for the health
and wastes electricity.

Keep blinds or curtains

closed.

Do not let direct sunshine
enter the room when the air
conditioner is in operation.

Keep the room temperature

uniform.

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.

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

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.

Ventilate the room

occasionally.

Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.
