Defrosting is underway (as the heating operation is stopped, the microcomputer
checks frost accumulated in the indoor unit and instructs the unit to perform
automatic defrosting if necessary).
This is the noise of the pump thoroughly discharging condensed water
accumulated during cooling or dehumidifying even after operation is stopped.
Actual room temperature may deviate slightly from the remote controller’s temperature
setting depending on the number of people in the room, indoor or outdoor conditions
and influence of other rooms’ conditions when the air conditioner is used for more
than one room at the same time.
The outdoor unit continues to operate
even if operation is stopped.
Does not reach the temperature
setting.
Even if the air conditioner operation is
stopped, noise will be generated from
the indoor unit.
• If the unit still fails to operate
normally after performing the
above inspections, turn the
circuit breaker off and contact
your sales agent immediately.
Contact your sales agent immediately if the
following phenomena should occur:
• The circuit breaker switches off or the fuse blows
frequently.
• The switch operation is not stable.
• Foreign matter or water accidentally enters the unit interior.
• The power cord gets excessively hot or its insulation is torn or
stripped.
• TIMER lamp on the indoor unit display blinks.
As the nature of the failure can be identified by the blinking cycle,
check the blinking cycle before turning off the circuit breaker.

Notes
• In quiet operation or stopping the running, the following phenomena may
occasionally occur, but they are not abnormal for the operation.
(1) Slight flowing noise of refrigerant in the refrigerating cycle.
(2) Slight rubbing noise from the fan casing which is cooled and then gradually
warmed as operation stops.
• The odor will possibly be emitted from the room air conditioner because the
various odor, emitted by smoke, foodstuffs, cosmetics and so on, sticks to it. So
please clean the air filter and the evaporator regularly to reduce the odor.
Note
• Avoid to use the room air conditioner for cooling operation when the outside temperature is below 21°C (70°F).
The recommended maximum and minimum operating temperatures of the hot and cold sides should be as
below:

• Please contact your sales agent immediately if the air conditioner still fails to operate normally after the above
inspections. Inform your agent of the model of your unit, production number, date of installation. Please also
inform him regarding the fault.
Please note:
On switching on the equipment, particularly when the room light is dimmed, a slight brightness fluctuation
may occur. This is of no consequence.
The conditions of the local Power Supply Companies are to be observed.
