[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION
•
As the frost on the coil of an outdoor unit increases,
heating effect decreases and the system goes into
DEFROST OPERATION.
•
The indoor unit fan stops and the remote control 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 declines as the
outside air temperature falls.
In such a case, use the air conditioner in combination with
other heating systems.
•
A warm air circulation 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
control 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.
For programming TEMPERATURE, FAN SPEED and AIR
FLOW DIRECTION, follow the procedure shown below.
