•  A place where the hot wind discharged from the air outlet of the outdoor unit and the running noises.
• Are you sure that there are no obstacles near the air outlet of the outdoor unit?
• uch obstacles may result in declined perfor-mance and increased running noises.
•  If abnormal noises occur in use, consult your dealer.

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.
•  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 “ ”. Leave it 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.
