Operation Tips

Operation and Performance
*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 insufficient
heating perfomance 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 first starting the air conditioner until the
room is heated.
Instructions relating to heating (*) are applicable
only to "HEAT & COOL TYPE".

*Microcomputer-controlled Automatic Defrosting
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.
