Operation and Performance
Heating Performance
●
This air conditioner operates on the heat-pump princi-
ple, absorbing heat from outdoor air and transferring
that heat to indoor unit. As a result, the operating per-
formance is reduced as outdoor air temperature drops.
If you feel that insuffi cient heating performance is being
produced, we recommend you use this air conditioner
in conjunction with another kind 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.
Microcomputer-controlled Automatic Defrosting
●
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 per-
formance.
In order to prevent this kind of reduced performance,
this air conditioner is equipped with a Microcomputer-
controlled Automatic Defrosting function. If frost forms,
the air conditioner will temporarily stop, and the de-
frosting circuit will operate briefl y (for about 7-15 min-
utes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will fl ash.
●
After heating operation stops, if frost forms on the out-
door unit, the unit will start Automatic Defrosting op-
eration. At this time, the outdoor unit will automatically
stop after operating for a few minutes.
