CAUTIONS

AIR EXHAUST LEVER

WASABI AIR PURIFYING FILTER

Set the air exhaust lever to the down ( OPEN) position for air ventilation in

the room. The air exhaust lever should normally be kept in up ( CLOSE)

position during cooling operation and in the case of typhoon.

NOTES ON OPERATION

TEMPERATURE AND HUMIDITY

Avoid to use the room air conditioner for cooling operation when the outside temperature is below 21°C (70°F). Recommended

operation humidity should be below 80%. Continuous operation at over 80% humidity (indoor) will cause some dews form

on the outlet grille and defl ectors of the unit.

NOISE

In a quiet environment during the starting or stopping the operation, phenomena like fl owing sound of refrigerant in the

refrigerating cycle and rubbing noise from the fan casing may occasionally occur, but this is normal for the operation.

Water will be condensed on the evaporator coil and collected in the bottom tray, it is picked up by the condenser fan and

blown onto the condenser coil, this creates a “splashing” sound which is normal.

ODOR

The odor will possibly be emitted from the room air conditioner especially at the starting of operation and in a high

humidity condition. This is not abnormal phenomena because of the various kind of odors emitted by smoke, food stuffs,

cosmetics and others which may stick to the room air conditioner. So, the pre-fi lter and the evaporator regularly must be

cleaned to reduce the odor.
