CONDITION CHECK THE FOLLOWING POINTS
Notes
● In quiet operation or stopping the operation, the following phenomena
may occassionally occur, but they are not abnormal for the operation.
(1) Slight owing 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 the air lter and the evaporator regularly must be cleaned
to reduce the odor.
● 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.
● Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could not reach
the speci ed capacity.

On switching on the equipment, particularly when the room light is dimmed, a slight brightness uctuation
may occur. This is of no consequence.
The conditions of the local Power Supply Companies are to be observed.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
