Basic Operation Method
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.
• It may take time until fan speed changes are actually carried
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.
• Depending on the type of indoor unit, there are two fan speeds
(low and high), three fan speeds (low, medium and high) or ve
fan speeds available (low, medium-low, medium, medium-high,
high). Some indoor units also support automatic fan speed.
• 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.

operation, the indoor unit fan will stop in order to prevent a cold draft.
(In that case, "" (Defrost/Hot start) will be displayed on the
remote controller).
• The heating capacity of the air conditioner will drop when the outdoor
temperature decreases.
If the heating effect is insufcient, it is recommended to use another
heating appliance in combination with the air conditioner. (When a
combustion appliance is used, ventilate the room regularly).
Do not use the heating appliance in places where the heating
appliance is exposed to the airow of the air conditioner.
• The air conditioner is a hot air circulation type. Therefore, it takes
some time to warm up the room after the air conditioner starts
operating.
The indoor fan will automatically operate until the indoor temperature
of the system rises to a certain level.
• If hot air stays around the ceiling and your feet feel cold, a circulator is
recommended.
For details, consult your Daikin dealer.
