If the problem persists after performing these checks, or if you notice burning smells, or the OPERATION Indicator Lamp (Fig. 3 5) and the TIMER Indicator Lamp (Fig. 3 6) flashes, immediately stop operation, disconnect the Power Supply Plug (Fig. 1 F), and consult authorized service personnel.

OPERATING TIPS

Operation and Performance

Heating Performance

Microcomputer-controlled Automatic Defrosting

●This air conditioner operates on the heat-pump princi- ple, 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 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.

●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 unit is equipped with a Microcomputer-controlled Auto- matic Defrosting function. If frost forms, the air condi- tioner will temporarily stop, and the defrosting circuit will operate briefly (for about 7-15 minutes).

During Automatic Defrosting operation, the OPERATION Indicator Lamp (red) will flash.

AUTO Restart

In Event of Power Interruption

●The air conditioner power has been interrupted by a power failure. The air conditioner will then restart auto- matically in its previous mode when the power is restored.

●Operated by setting before the power failure.

●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 flash (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 disconnect the Power Supply Plug, reconnect it, and then use the Remote Control Unit to resume operation.
