Stopping the system
Press the on/off button once again.
The operation lamp goes off and the system
stops operation.
NOTE
• Do not turn off power immediately after the
unit stops.
• The system needs at least 5 minutes for the
residual operation of drain pump.
Turning the power off immediately will cause
water leak or trouble.
EXPLANATION OF HEATING OPERATION
• For general heating operation, it may take longer
to reach the set temperature than in cooling oper-
ation.
We recommend starting the operation which was
used before using timer operation.
• The following operation is performed in order to
prevent the heating capacity from dropping or
cold air from blowing.
Defrost operation
• In heating operation, freezing of the outdoor
unit coil increases. Heating capability
decreases and the system goes into defrost
operation.
• The indoor unit fan stops and the remote
controller displays
“
”.
• After maximum 10 minutes of defrost operation,
the system returns to heating operation again.
Hot start
• In order to prevent cold air from blowing out
of an indoor unit at the start of heating oper-
ation, the indoor fan is automatically
stopped. The display of the remote controller
shows “
”.
NOTE
• The heating capacity drops as the outside
temperature falls. If this happens, use
another heating device together with the
unit. (When using the appliances which pro-
duce open fire together, ventilate a room
constantly.)
Do not place appliances which produce
open fire in places exposed to the air flow
from the unit or under the unit.
• It takes some time for the room to warm up
from the time the unit is started since the unit
uses a hot-air circulatory system to warm
the entire room.
• If the hot air rises to the ceiling, leaving the
area above the floor cold, we recommend
using the circulator (the indoor fan for circu-
lating air). Contact your dealer for details.

the humidity in your room with a minimum

mines temperature and fan speed.

perature is 68°F or lower.
