Note
• The air conditioner may be in automatic fan speed control for
mechanical protection purposes.
• The air conditioner may be in automatic fan speed control
according to the room temperature.
• The fan may stop operating, which is not a failure.

out.
• In Auto mode, the fan speed is adjusted automatically
according to the setpoint and indoor temperature
• In case of Fan Only mode the fan speed is high.

• When the ON/OFF button is pressed again, the air
conditioner will stop operating and the Operation
lamp will turn OFF.
Note
• When the system is stopped while in heating operation, the fan
will continue to operate for approximately 1 minute in order to
eliminate the residual heat in the indoor unit.
• To prevent water leakage or system failure, do not turn OFF the
power soon after the air conditioner stops operating. Be sure to
wait at least 5 minutes so that the drain pump nishes
discharging the residual water from the indoor unit.
Characteristics of Cooling Operation
• If the cooling operation is used when the room temperature is too low,
frost forms on the heat exchanger of the indoor unit which can
decrease the cooling capacity. In this case, the air conditioner
automatically switches to defrost operation for a while.
During defrost operation, a low airow rate or a gentle wind is used to
prevent the discharge of melt water. (The remote controller displays the
fan speed that is set).
• When the outdoor air temperature is high, it takes some time until the
room temperature reaches the set temperature.
