curs.

 

If the air conditioner had operated before the

 

 

power failure, as these models are equipped with

 

 

an auto restart function, the air conditioner

 

 

should start operating again. (Refer to Descrip-

 

 

tion of “AUTO RESTART FUNCTION” on page

 

 

6.)

 

 

 

Even if the above items are checked, when the air conditioner does not recover from the trouble, stop using the air conditioner and consult your dealer.

In the following cases, stop using the air conditioner and consult your dealer.

When water leaks or drops from the indoor unit.

When the left operation indicator lamp blinks.

When the breaker trips frequently.

The remote control signal may not be received in a room where an electronic ON/OFF type fluorescent lamp (inverter-type fluorescent lamp, etc.) is used.

Operation of the air conditioner may interfere with radio or TV reception in areas where the reception is weak. An amplifier may be required for the af- fected device.

When thunder is heard, stop operation and turn off the breaker. Otherwise, the electrical parts may be damaged.
