÷ Dust can be cleaned from the Air Filter either with a
vacuum cleaner, or by washing the filter in a solution of
mild detergent and warm water. If you wash the filter,
be sure to allow it to dry thoroughly in a shady place
before reinstalling.
÷ If dirt is allowed to accumulate on the Air Filter, air flow
will be reduced, lowering operating efficiency and
increasing noise.
÷ During periods of normal use, the Air Filters should be
cleaned every two weeks.

Doesn’t operate immediately:
÷ If the unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to
prevent fuse blowouts.
÷ Whenever the Power is disconnected and then reconnected to
a power outlet, the protection circuit will operate for about 3
minutes, preventing unit operation during that period.
––––
÷ During operation and immediately after stopping the unit, the
sound of water flowing in the air conditioner’s piping may be
heard. Also, noise may be particularly noticeable for about 2
to 3 minutes after starting operation (sound of coolant flowing).
÷ During operation, a slight squeaking sound may be heard. This
is the result of minute expansion and contraction of the front
cover due to temperature changes.
––––
÷ Some smell may be emitted from the indoor unit. This smell is
the result of room smells (furniture, tobacco, etc.) which have
been taken into the air conditioner.

Noise is heard:
Smells:
Mist or steam are emitted:
Airflow is weak or stops:
÷ During Cooling or Dry operation, a thin mist may be seen
emitted from the indoor unit. This results from the sudden
Cooling of room air by the air emitted from the air conditioner,
resulting in condensation and misting.
––––
÷ The fan may operate at very low speed during Dry operation
or when the unit is monitoring the room’s temperature.

OPERATING TIPS
Operation and Performance
In Event of Power Interruption
Auto Restart
÷ The air conditioner power has been interrupted by a
power failure. The air conditioner will then restart
automatically in its previous mode when the power is
restored.
÷ Operated by settings before the power failure. Then, the
Air Flow Direction Louvers will automatically change to
their standard direction.
En-17
÷ If a power failure occurs during TIMER operation, the
timer will be reset and the unit will begin (or stop)
operation at the new time setting. In the event that this
kind of timer fault occurs, the TIMER Indicator Lamp
(green) will flash (see page 5).
÷ Use of other electrical appliances (electric shaver, etc.)
or nearby use of a wireless radio transmitter may cause
the air conditioner to malfunction. In this event,
temporarily disconnect the Power, reconnect it, and then
use the Remote Control Unit to resume operation.
