● 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?

WARNING!
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Please read and understand the following details regarding this air conditioner.
Malfunction
Nearby lightning or use of a mobile radio (short wave, etc.) may result in malfunction. In this case, disconnect the power plug
from its outlet and connect it again, then use the remote control unit to resume operation.
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 airflow-direction louvers will automatically change to their standard direction.
● 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 will flash.
