Never touch the internal parts of the remote
controller.
Do not remove the front panel. Touching certain
internal parts will cause electric shocks and
damage to the unit. Please consult your dealer
about checking and adjustment of internal parts.
Do not leave the remote controller wherever
there is a risk of wetting.
If water gets into the remote controller there is a
risk of electrical leakage and damage to elec-
tronic components.
• NOTE TO SURVICE PERSONNEL
CAUTION
Read the following for the safety.
Do not operate the unit while the suction grille is
open.
•
Fan may rotate and cause accident.
Make sure to screw the suction grille stopper.
•
If the screw is not completely tightened, the suc-

WARNING
May cause electric shock, ignition, fire
•
Before starting the inspection of the electrical
parts (control box, fan motor, drain pump, etc.),
be sure cut off the all air-conditioner power (adap-
tor for wiring power is included) or you may get an
electric shock.
•
When cleaning the heat exchanger, be sure to
remove the switch box, fan motor and drain
pump.
Water or detergent may deteriorate the insulation
of electric components and result in burn-out of
these components.

CAUTION! ELECTRIC SHOCK
•
Due to high voltage, do not open control box lid for
ten minutes after the safety breaker is switched
off.
•
After the box is opened, measure the voltages of
the points shown below printed circuit board with
a tester and confirm that the voltages are not
higher than DC50V.
Do not touch live parts when carrying out this work.
•
After power failure, operation will restart automat-
ically.
If the temperature or the humidity is beyond the fol-
lowing conditions, safety devices may work and the
air conditioner may not operate, or sometimes,
water may drop from the indoor unit.
