• The system need at least 5 minutes for
residual operation of drain pump device.
Turning off the power 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 operation.
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 heat exchanger 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 opera-
tion, 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 tem-
perature falls. If this happens, use another heat-
ing device together with the unit. (When using the
appliances which produce open fire together, ven-
tilate 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 cir-
culator (the indoor fan for circulating air). Contact
your dealer for details.
6-2 PROGRAM DRY OPERATION
• The function of this operation is to decrease
the humidity in your room with a minimum
temperature decrease.
• The micro computer automatically deter-
mines temperature and fan speed.
• The system does not go into operation if the
room temperature is low.
• The microcomputer automatically controls
the temperature and fan speed, so these
cannot be set using the remote controller.
• This function is not available if the room tem-
perature is 20°C or lower.
