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 indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insuffi- cient heating performance is being produced, we recom- mend 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 out- door air temperature 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 briefly (for about 7 to 15 minutes).

During Automatic Defrosting operation, the OPERATION indicator lamp (red) will flash.

*When Indoor and Outdoor Temperatures are High

When both indoor and outdoor temperatures are high dur- ing use of the heating mode, the outdoor unit’s fan may stop at times.

*Low Ambient Cooling

When the outdoor temperature drops, the outdoor unit’s fans may switch to Low Speed.
