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 long operation at
over 80% humidity (indoor) will cause some dews form on the outlet grille of the unit.
NOISE
In a quiet environment or stopping and starting operation, phenomena like flowing noise 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 condense 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" noise 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, please clean the air filter and evaporator at the beginning of long no operation period to reduce
the odor.
