Explanation of heating operation
Master-slave unit system (mode batting)
■
System operation mode cool or heat is determined by the mode
the master unit is in. When the master unit is in cool mode,
respectively heat mode, the system can only operate in cooling,
respectively heating, regardless of the thermostat setting.
■
When the master unit is OFF, the system mode is determined by
the unit which is switched on first.
NOTE
The master-slave setting is decided upon and set
during installation.
O
PTIMUM OPERATION
Observe the following precautions to ensure the system operates
properly.
■
Adjust the air outlet properly and avoid direct air flow to room
inhabitants.
■
Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.
■
Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.
■
Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room causing a decrease in
the cooling or heating effect.
■
Never place objects near the air inlet or the air outlet of the unit.
It may cause deterioration in the effect or stop in the operation.
■
Turn off the main power supply switch to the unit when the unit is
not used for longer periods of time. If the switch is on, it uses
electricity. Before restarting the unit, turn on the main power
supply switch 6 hours before operation for smooth running.

The system does not start immediately after the power supply is
turned on.
Wait one minute until the micro computer is prepared for
operation.
White mist comes out of a unit
■
When humidity is high during cooling operation (in oily or dusty
places)
If the inside of an indoor unit is extremely contaminated, the
temperature distribution inside a room becomes uneven. It is
necessary to clean the inside of the indoor unit. Ask your Daikin
dealer for details on cleaning the unit. This operation requires a
qualified service person.
■
When the system is changed over to HEATING OPERATION
after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and exits.
Noise of air conditioners
■
A continuous low "hissing" sound is heard when the system is in
COOLING or DEFROST OPERATION.
This is the sound of refrigerant gas flowing through both indoor
and outdoor units.
■
A "hissing" sound which is heard at the start or immediately after
the stop of operation or which is heard at the start or
immediately after the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow stop and flow
change.
