Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
Heat-pump air conditioners heat our entire room
b recirculating air throughout the room, with the
result that some time ma 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 ou feel that insufficient
heating perfomance is being produced, we
recommend ou 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 humidit , frost
ma 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
temporaril stop, and the defrosting circuit will
operate briefl (for about 7 to 12 minutes).
During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.
*Trouble alarming performance
During operation, when there is an trouble,
the operation indicator lamp will flash with different
times.
Operation Tips
Temperature and Humidity Range
If the air conditioner is used under higher temperature condition than those listed, the built-in protection
circuit ma operate to prevent internal circuit damage. Also, during Cooling and Dr modes, if the unit is
used under conditions of lower temperature than those listed above, the heat-exchanger ma freeze, leading
to water leakage and other damage.
Do not use this unit for an other purposes except for the Cooling, Heating, Dehumidif ing, and air-
circulation of rooms in ordinar dwellings.
The wiring method should be in line with the local wiring standand.
The waste batter should be disposed properl .
If the fuse on PC board is broken, please change it with the t pe T 3.15A/250VAC.
The indoor unit installation height is at least 2.5m.
