Notes
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.
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.
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.
