OPERATING 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 insuf 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 recir-
culating air throughout the room, with the result that some
time may be required after rst starting the air conditioner
until the room is heated.
AUTO Restart
In Event of Power Interruption
● The air conditioner power has been interrupted by a power
failure. The air conditioner will then restart automatically in
its previous mode when the power is restored.

Microcomputer-controlled Automatic Defrosting
● When using the Heating mode under conditions of low out-
door 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 function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate brief-
ly (for max. 15 minutes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will ash.
● After heating operation stops, if frost forms on the outdoor
unit, the unit will start Automatic Defrosting operation. At
this time, the outdoor unit will automatically stop after oper-
ating for a few minutes.
(However, some type of multi-type air conditioner doesn't
provide this function.)
● If a power failure occurs during TIMER operation, the timer will
be reset and the unit will begin (or stop) operation at the new
time setting. In the event that this kind of timer fault occurs the
TIMER Indicator Lamp will ash (see Page. 3).
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily discon-
nect the Power Supply Plug, reconnect it, and then use the
Remote Controller to resume operation.
