Operation Procedure - Daikin FHQ71BUV1B Operation Manual

Regarding drainage of drain piping
• Is the drain piping executed to perform com-
plete drainage?
If proper drainage is not carried out from the out-
door drain pipes during air-conditioning operation,
chances are that dust and dirt are clogged in the
pipe. This may result in a water leakage from the
indoor unit. Under such circumstances, stop the
operation of the air conditioner, and then consult
your dealer or our service station.

5. OPERATION PROCEDURE

Read the operation manual that came with the
remote controller.
• Operating procedure varies with heat pump type
and cooling only type. Contact your Daikin dealer
to confirm your system type.
• To protect the unit, turn on the main power switch
6 hours before operation.
• If the main power supply is turned off during oper-
ation, operation will restart automatically after the
power turns back on again.
[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION
• As the frost on the coil of an outdoor unit increase,
heating effect decreases and the system goes
into DEFROST OPERATION.
• The indoor unit fan stops and the remote control-
ler display shows "
• After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
Regarding outside air temperature and heat-
ing capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in combina-
tion with other heating systems.
• A warm air circulating system is employed, and
therefore it takes some time until the entire room
is warmed up after the start of operation.
• An indoor fan runs to discharge a gentle wind
automatically until the temperature inside the air
conditioner reaches a certain level. At this time,
the remote controller displays "
as it stands and wait for a while.
• When the warm air stays under the ceiling and
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room). For details, consult your dealer.
