Contact Your Sales Agent Immediately If The Following Phenomena Should Occur - Hitachi RAK-18PPA Manual De Instrucciones

Perking noise
Changing operation noise
Mist emission
Steam emitted from the outdoor unit
Odors
The outdoor unit continues to operate
even if operation is stopped.
The OPERATION lamp is blinking.
Does not reach the temperature
setting
• If the unit still fails to operate
normally after performing the
above inspections, turn the
circuit breaker off, or pull the
power plug out, and contact
your sales agent immediately.
• 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.
Noise of the ventilation fan sucking in air present in the drain hose and blowing out
dehumidifying water that had accumulated in the condensed water collector. For
details, consult your sales agent.
Operation noise changes due to power variations according to room temperature
changes.
Mist is generated as the air within the room is suddenly cooled by conditioned air.
Water generated during defrosting operation evaporates and steam is emitted.
Caused as the smells and particles of smoke, food, cosmetics, etc. present in room
air become attached the unit and blown off into the room again.
Defrosting is underway (as the heating operation is stopped, the microcomputer
checks frost accumulated in the outdoor unit and instructs the unit to perform
automatic defrosting if necessary).
Shows preheating or defrosting operation is underway.
As the protective circuit or preheat sensor operates when unit operation is stopped
during preheating and then restarted, or when operation mode is switched from cooling
to heating, the lamp continues to blink.
Actual room temperature may deviate slightly from the remote controller's
temperature setting depending on the number of people in the room, indoor or
outdoor conditions.
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.
(1) Slight flowing noise of refrigerant in the refrigerating cycle.
(2) 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.
