Care and aintenance

When the air conditioner is not going to be used for a long time

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

Operate the air conditioner on Air circulation mode for 2 to 3 hours.

•

This will dry out the internal parts.

Turn off the circuit breaker.

CAUTION: 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.

When the air conditioner is to be used again.

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

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.

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.

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

Ventilate the room occasionally.

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

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.
