Items to check

Has there been a power failure?

Has a fuse blown out, or a circuit breaker been tripped?

Is the main power switch set to the OFF position?

Is the timer operating?

Is the air filter dirty?

Are the air conditioner’s intake grille or outlet port blocked?

Did you adjust the room temperature settings (thermostat) cor-
rectly?

Is there a window or door open?

In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)

In the case of Cooling operation, are there heating apparatus and
computers inside the room, or are there too many people in the
room?

If the problem persists after performing these checks, or if you notice burning smells, stop operation immediately, turn off the
electrical breaker, and consult with authorized service personnel.

OPERATING TIPS

*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 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.

Cooling/Heating Priority (HEAT PUMP MODEL only)

If another indoor unit in the same refrigerant system is
already operating in the cooling mode or dry mode, heat-
ing mode settings cannot be performed. (Operation in
the cooling or dry mode will continue.)

If another indoor unit in the same refrigerant system is
already operating in the heating mode, cooling mode or
dry mode settings cannot be performed. (Operation in
the heating mode will continue.)

Operation and Performance

*Microcomputer-controlled Automatic Defrosting

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 2 to 16 minutes).

During Automatic Defrosting operation, the OPERATION in-
dicator lamp (red) will flash.

Oil Recovery Operation

Periodically, the oil recovery operation is performed in or-
der to return compressor oil to the outdoor unit.  Operation
is stopped during this oil recovery operation.  During oil re-
covery operation, the OPERATION indicator lamp will flash.

Low Ambient Cooling

When the outdoor temperature drops, the outdoor unit’s fans
may switch to Low Speed, or one of the fans may stop inter-
mittently.
