If the problem persists after performing these checks, or if you notice burning smells, or the TIMER Indicator Lamp (Fig. 3 6) and OPERATION Indicator Lamp (Fig. 3 5) flashes, immediately stop operation, disconnect the Power Supply Plug, and con- sult 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.
