Items to check
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
● Is the 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?
● Is a window allowing bright sunlight to enter? (Close the curtains.)
● Are there heating apparatus and computers inside the room, or
are there too many people in the room?
● Is the unit set for SUPER QUIET operation?
● Are the Remote Control Unit’s batteries dead?
● Are the Remote Control Unit’s batteries loaded properly?
OPERATING TIPS
Operation and Performance
In Event of Power Interruption
AUTO Restart
● 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 (green) will flash
(see page. 5).
● 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, reconnect it, and then use the re-
mote control unit to resume operation.
● The air conditioner power has been interrupted by a power
failure. The air conditioner will then restart automatically in its
previous mode when the power is restored.
● Operated by setting before the power failure. Then, the Air
Flow Direction Louvers will automatically be restored to the
direction before the power failure.
If the problem persists after performing these checks, or if you notice burning smells, or the
TIMER indicator Lamp (Fig. 3 6) flashes, immediately stop operation, disconnect the Power and
consult authorized service personnel.
