Items to check

Has there been a power failure?

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

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?

Are the remote control unit’s batteries dead?

Are the remote control unit’s batteries loaded properly?

Are you using an air conditioner signal code other than signal
code A?

*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.

*When Indoor and Outdoor Temperature are High

When both indoor and outdoor temperatures are high
during use of the heating mode, the outdoor unit’s fan
may stop at times.

*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-
formance.

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 to 15 minutes).

During Automatic Defrosting operation, the OPERATION
indicator lamp (red) will flash.

*Low Ambient Cooling

When the outdoor temperature drops, the outdoor unit’s
fans may switch to Low Speed.

If the problem persists after performing these checks, or if you notice burning smells, or the TIMER indicator lamp flashes, stop
operation immediately, disconnect the power supply plug, and consult with authorized service personnel.
