Operation and Performance
Heating Performance
● 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.
AUTO Restart
In Event of Power Interruption
● The air conditioner power has been interrupted by a
power failure. The air conditioner will then restart auto-
matically in its previous mode when the power is restored.
● Operated by setting before the power failure.
Temperature and Humidity Range
Outdoor temperature
Indoor temperature
● If the air conditioner is used under higher temperature conditioner 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 purposes other than the Cooling, Dehumidifying, and air-circulation of rooms in ordinary
● If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)
Microcomputer-controlled Automatic Defrosting
● 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-
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 (green) will flash.
● If a power failure occurs during TIMER operation, the timer
will be reset and the unit will begin (or stop) operation at the
new time setting. In the event that this kind of timer fault
occurs the TIMER Indicator Lamp will flash (see Page. 4).
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the
air conditioner to malfunction. In this event, temporarily
disconnect the Power Supply Plug, reconnect it, and then
use the Remote Control Unit to resume operation.
