OPERATING TIPS

Operation and Performance
In Event of Power Interruption
Auto Restart
÷ 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 settings before the power failure. Then, the
Air Flow Direction Louvers will automatically change to
their standard direction.
En-17
Symptom
÷ 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)
correctly?
÷ 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?
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.
Items to Check
÷ 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 Remote Control Unit to resume operation.
