Operation Procedure - Daikin FAQ71BUV1B Operation Manual

• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
• If abnormal noises occur in use, stop the opera-
tion of the air conditioner, consult your dealer.
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.

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.
