Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
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.
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.
Instructions relating to heating (*) are applicable
only to "HEAT & COOL TYPE".
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).
During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.
*Trouble alarming performance
During operation, when there is any trouble,
the power indicator lamp will flash.
Operation Tips
Temperature and Humidity Range
If the air conditioner is used under higher temperature condition than those listed, the built-in protection
circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is
used under conditions of lower temperature than those listed above, the heat-exchanger may freeze, leading
to water leakage and other damage.
Do not use this unit for any other purposes except for the Cooling, (*) Heating, Dehumidifying, and air-
circulation of rooms in ordinary dwellings.
The wiring method should be in line with the local wiring standand.
The waste battery should be disposed properly.
If the fuse on PC board is broken, please change it with the type T 3.15A/250VAC.
