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.
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.
Check that the ground wire is
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. Do not let direct sunshine enter
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.
Dirt may collect and may cause a fire.
