[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION
As the frost on the coil of an outdoor unit in-
•
crease, 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
heating capacity
The heating capacity of the air conditioner de-
•
clines as the outside air temperature falls. In this
case, use the air conditioner in combination 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.

SPEED, follow the procedure shown below.
TEMPERATURE SETTING
Press TEMPERATURE SETTING button and

OPTIMUM OPERATION
7.
Observe the following precautions to ensure the
system operates.
Adjust the room temperature properly for a com-
•
fortable environment. Avoid excessive heating or
cooling.
Prevent direct sunlight from entering a room
•
during cooling operation by using curtains or
blinds.
Ventilate the room regularly.
•
Using the unit for long periods of time requires
attentive ventilation of the room.
Keep doors and windows closed. If the doors
•
and windows remain open, room air will fl ow out
and cause to decrease the effect of cooling and
heating.
Never place objects near the air inlet and 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 when it is
•
not used for long periods of time. When the main
power switch is turned on, some watts of elec-
tricity is being used even if the system is not
operating. Turn off the main power supply switch
for saving energy. When reoperating, turn on the
main power supply switch 6 hours before opera-
tion for smooth running (Refer to MAINTE-
NANCE).
When the display shows “
•
”, ask a qualifi ed
service person to clean the fi lters (Refer to
MAINTENANCE).
