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 follow-
ing 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 con-
nected 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.
This is not good for the health
and wastes electricity. Do not let direct sunshine
enter the room when the air
conditioner is in operation. Adjust the vertical and hori-
zontal airflow direction to en-
sure a uniform temperature in
the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly. Ventilate the room occasion-
ally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the
room. Blockages in the air filter re-
duce the airflow and lower
cooling and dehumidifying ef-
fects. 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.
