If the unit still fails to operate normally after
performing the above inspections, turn the
circuit breaker off and contact your sales agent
immediately.
Contact your sales agent immediately if the
following phenomena should occur.
• The circuit breaker switches off or
the fuse blows frequently.
• The switch operation is not stable.
• Foreign matter or water accidentally enters the
unit interior.
• The power cord gets excessively hot or its
insulation is torn or stripped.
• TIMER lamp on the indoor unit display blinks.
(As the nature of the failure can be identified
by the blinking cycle, check the blinking cycle
before turning off the circuit breaker.)
Notes:
• In quiet operation or stopping the
running, the following phenomena
may occasionally occur, but they are
not abnormal for the operation.
a. Slight flowing noise of refrigerant in the
refrigerating cycle.
b. Slight rubbing noise from the fan casing which
is cooled and then gradually warmed as
operation stops.
• The odor will possibly be emitted from the
room air conditioner because the various odor,
emitted by smoke, foodstuffs, cosmetics and so
on, sticks to it. So please clean the air filter and
the evaporator regularly to reduce the odor.
Please contact your sales agent immediately if the
air conditioner still fails to operate normally after
the above inspections. Inform your agent of the model
of your unit, production number, date of installation.
Please also inform him regarding the fault.
Please note:
On switching on the equipment, particularly when
the room light is dimmed, a slight brightness
fluctuation may occur. This is of no consequence.
The conditions of the local Power Supply
Companies are to be observed.
