OPERATING TIPS
If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp
(Fig. 3 a-5) and the TIMER Indicator Lamp (Fig. 3 a-6) flashes, immediately stop operation, disconnect the Power Supply
Plug, and consult authorized service personnel.
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 perform-
ance is reduced as outdoor air temperature drops. If you
feel that insufficient 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 first starting the air con-
ditioner 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
defrosting circuit will operate briefly (for about 7-15 min-
utes).
During Automatic Defrosting operation, the OPERATION
Indicator Lamp (green) will flash.
AUTO Restart
In Event of Power Interruption
●
The power supply to the air conditioner is stopped by a
power interruption. The air conditioner will then restart
automatically in its previous mode when the power is
restored.
●
If a power interruption occurs during TIMER operation, the
timer will be reset and the indoor 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 flash
(see Page. 4).
●
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
disconnect the Power Supply Plug, reconnect it, and then
use the Remote Control Unit to resume operation.
