OPERATION DETAILS
*Heating Performance
● This air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insuffi-
cient heating performance is being produced, we recom-
mend 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 first starting the air con-
ditioner until the room is heated.
Operation and Performance
*Microcomputer-controlled Automatic Defrosting
When using the Heating mode under conditions of low out-
door air temperature 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 function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate
briefly (for about 6 to 12 minutes).
During Automatic Defrosting operation, the OPERATION in-
dicator lamp (red) will flash.
*When Indoor and Outdoor Temperatures are High
When both indoor and outdoor temperatures are high dur-
ing use of the heating mode, the outdoor unit’s fan may stop
at times.
*Low Ambient Cooling
When the outdoor temperature drops, the outdoor unit’s fans
may switch to Low Speed.
