OPERATING TIPS
Instructions relating to heating (*) are applicable only to Heating and Cooling model (Reverse Cycle).
Heating performance
This air conditioner operates on the heat-pump principle,
●
absorbing heat from air outdoors and transferring that heat
to the indoor unit. As a result, the operating performance is
reduced as outdoor air temperature drops. If you feel that the
heating performance is insuffi cient, we recommend you to use
this air conditioner in conjunction with other kinds of heating
appliance.
Heat-pump air conditioners heat your entire room by
●
recirculating air throughout the room, with the result that some
time may be required after fi rst starting the air conditioner until
the room is heated.
When indoor and outdoor temperatures are high
When both indoor and outdoor temperatures are high during use
of the Heating mode, the outdoor unit's fan may stop at times.

Problem
Automatic Defrosting operation*
When using the Heating mode under conditions of low outdoor
●
temperature and high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this
unit is equipped with a microcomputer-controlled Automatic
Defrosting operation. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate briefl y
(for about 4 to 15 minutes).
During the Automatic Defrosting operation, the Operation
indicator lamp (green) will blink.
After the Heating mode operation stops, if frost forms on
●
the outdoor unit, the unit will start the Automatic Defrosting
*
operation. At this time, the outdoor unit will automatically stop
after operating for a few minutes.
Low ambient cooling
When the outdoor temperature drops, the outdoor unit's fans
may switch to low speed.
Hot start (for Heating mode)
The indoor unit prevents cold drafts when the Heating mode
operation begins.
The indoor unit fan will not operate or it will operate at a very low
speed until the heat exchanger reaches the set temperature.
