[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 controller 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 this case, use the air condi-
tioner 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 cer-
tain 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 circu-
late the air inside the room). For details, consult your dealer.
