Operation Tips Operation and Performance *Heating Performance 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 insufficient heating perfomance 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 conditioner until the room is heated. Instructions relating to heating (*) are applicable only to "HEAT & COOL TYPE". Accessories for installation The following parts mentioned in this manual are the installation parts . Mark A B Optional parts Parts name Adhesive tape Saddle (L.S) with screws C Drain hose D Heat insulation material E Piping hole cover F Putty G Plastic clamp *Microcomputer-controlled Automatic Defrosting When using the Heating mode under conditions of low outdoor 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). 10
