Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
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 conditioner until the
room is heated.
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 insufficient
heating perfomance is being produced, we
recommend you use this air conditioner in
conjunction with another kind of heating
appliance.
Instructions relating to heating (*) are applicable
only to "HEAT & COOL TYPE".
When using the Heating mode under
conditions of low outdoor 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 7 to 15 minutes).
During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.
