OPERATION.
• The fan may keep on running for about 1 minute after
the heating operation stops.
(To start the next operation smoothly.)
ATTENTION:
• Do not turn OFF power immediately after the unit stops.
Then, wait no less than 5 minutes. Water is leaking or
there is something else wrong with the unit.
• When the operation is started again immediately after being
stopped, when the operation mode is changed over, or when
the TEMPERATURE SETTING button is pressed then
returned soon, the air conditioner will start the operation
automatically about 5 minutes later (because the air condi-
tioner is controlled so that excessive load is not applied).
Characteristics of the heating operation
(1) 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 dis-
plays shows “
” (DEFROST/HOT START).
• After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to HEAT-
ING OPERATION.
(2) HOT START
• In order to prevent cold air from blowing out of an
indoor unit at the start of heating operation, the indoor
fan is automatically stopped. The display of the remote
controller shows “
” (DEFROST/HOT START).
(3) OPERATION START
• For ordinary heating, it will take longer for the room
temperature to reach the set temperature than with
cooling. We therefore recommend starting the unit
ahead of time using the timer operation.
