ELECTRIC WORK
This air conditioner employs a “Slinger-Up System” which is designed to splash the condensed water on the condenser coil
for maximum cooling efficiency, thus producing a splashing sound. If the splashing sound annoys you, you can provide an
outside drainage by using the following the procedure which may, cause a small loss of performance.
NOTE: If the unit is installed at a coastal area, drainage of condensed water is recommended to prevent easy condenser corrosion.
NOTE:
Remove the rubber plug and chassis locking
bracket from the cabinet. Then slides the chassis
out from the cabinet.

NOISE CONSIDERATION
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 when installed, airflow and noise from the rear side of the
unit (outdoor) do not disturb neighbouring elements.
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.
TRANSFERRING
Repositioning or transfer of the air conditioner due to renovation or moving requires an additional
service charge. Please consult your dealer before moving.
ENERGY SAVING HINTS
Do not overcool the room. This may affect your well-being as well as increase power consumption.
The cooling capacity of the room air conditioner must match the room size for efficient and
satisfactory operation.
Keep all doors and windows closed. Prevent hot air from entering and cool air from escaping.
Ensure that curtains and drapes are always closed to keep out direct sunlight during cooling operation.
Avoid heat.
Clean the air filter every 2 weeks. Dirty filters may reduce cooling efficiency.
CARE AND MAINTENANCE
Clean the cabinet, front grille with mild soap or detergent and lukewarm water.
NOTE: Do not dry the front panel or the air filter in direct sunlight.
(Exposure to direct sunlight may discolour or deform the panel.)
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.
If the unit is extremely dirty, heat transfer is less effecient and the unit may not cool effectively. Contact
Shun Hing Electric Service Center Ltd. for an annual check. (Annual check is not covered by the warranty.)
Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals.
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 spoiled, wash with a mild household detergent.
The front intake grille can be easily removed for cleaning purposes (refer to Remove the front intake
grille procedures). Gently wash it with water and a sponge.
PRE-SEASON INSPECTION
Is the discharged air cold?
Are the air intake and outlet vanes of the indoor and outdoor side obstructed?
Are the remote control batteries weak?
After 15 minutes of operation, it is normal for the temperature difference between intake and outlet air
to be more than 8
°
C for cooling.
RECOMMENDED INSPECTION
BEFORE CALLING FOR SERVICE
Usage over several seasons will reduce performance as the unit becomes dirty. A dirty unit may produce foul
odours and dust may clog the dehumidifying drainage. Seasonal inspection is recommended in addition to
regular cleaning. Consult Shun Hing Electric Service Centre Ltd.,
Check the following points before calling for repairs or service.
If the malfunction persists, please contact Shun Hing Electric Service Centre Ltd.,
