OPERATING TIPS

Operation and Performance

Heating Performance Microcomputer-controlled Automatic Defrosting

●This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat to indoor unit. 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 recir- culating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

AUTO Restart

In Event of Power Interruption

●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 air conditioner is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air con- ditioner will temporarily stop, and the defrosting circuit will operate briefly (Max. 15 minutes).

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

●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.

●The power supply to the air conditioner is stopped by a power interruption. The air conditioner will then restart auto- matically in its previous mode when the power is restored.

●If a power interruption occurs during TIMER operation, the tim- er 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 turn off the circuit breaker, turn it on and then use the Remote Con- troller to resume operation.
