8.7. Noise Considerations
•
•
•
•
Select an installation location that can support the weight of
the air conditioner and one that will not cause increased
operating noise and vibration.
•
•
•
•
Ensure that airflow and noise from the rear side of the unit
(outdoor) when installed, do not disturb neighbouring
residents.
•
•
•
•
Obstacles placed in front of the air outlet on the rear side of
the unit (outdoor), or covers placed over it will cause
excessive noise and deterioration in performance.
8.8. Transferring
•
•
•
•
When the air conditioner is to be repositioned or transferred
due
to
renovations,
or
moving,
the
removal
and
reinstallation of the unit requires an additional service
charge. Please consult your dealer before moving.
9 Care and Maintenance
Caution:
Always turn off the air conditioner and the main power supply before unplugging the power cord to clean the unit.
Switch off the power supply if the unit is not going to be used for a long period of time.
•
•
•
•
Clean the cabinet, front grille with a mild soap or detergent and lukewarm water.
•
•
•
•
The front intake grille can be easily removed for cleaning purposes (refer Removal of Front Grille procedures). Gently wash
it with water and a sponge.
•
•
•
•
The filter can be easily cleaned using a vacuum cleaner. Vacuum the front of the filter and then wash the rear with water. If it
is badly soiled, wash with a mild household detergent.
•
•
•
•
Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals.
•
•
•
•
If the unit is extremely dirty, heat transfer is less efficient and the unit may not cool effectively. Contact Shun Hing Electric
Service Centre Ltd. for an annual check. (Annual check is not covered under warranty)
•
•
•
•
If the air filter becomes clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air
conditioner will be wasted.
NOTE
Do not dry the front panel or the air filter in direct sunlight. (Exposure to direct sunlight may discolour or deform the panel.)
