NOT MALFUNCTION OF THE AIR CONDITIONER
The following symptoms do not
indicate air conditioner malfunction.
1. THE AIR CONDITIONER DOES NOT
OPERATE
•
The air conditioner does not restart
immediately after the ON/OFF button
is pressed.
• If the INDICATION lamp lights, the air
conditioner is in normal condition.
• It does not restart immediately because
a safety device operates to prevent
overload of the air conditioner.
After approx. 3 minutes, the air
conditioner will turn on again
automatically.
2. WHITE MIST COMES OUT OF THE
AIR CONDITIONER
•
When humidity is high during the
COOLING OPERATION (In oily or
dusty places)

is extremely contaminated, the
temperature distribution inside a room
becomes uneven. It is necessary to
clean the inside of the indoor unit. Ask
your local dealer for details on cleaning
the indoor unit.

service person.

fl owing through both indoor and outdoor
units.
