1 SAFETY PRECAUTIONS
Please observe these following safety precautions when using your air conditioner. Failure or negligence in observing these safety precautions could cause fire, electrical shock or personal injury.
This sign warns of risk of death or serious injury.
This symbol (with a white background) denotes an action that is PROHIBITED.
This sign warns of risk of injury or damage to property.
These symbols (with a green background) denote actions that are COMPULSORY.
INSTALLATION PRECAUTION
Do not install, remove and reinstall the unit yourself. Improper installation may cause Leakage, electric shock or fire. Please engage an authorized dealer or specialist for the installation work. Do not add or replace refrigerant other than the specified type. It may cause product damage, burst and injury. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similar qualified persons in order to avoid hazard.
The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an operating electric heater)
In cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction.
Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.
Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source, it can cause the generation of toxic gas.
The room air conditioner must be earthed. Improper grounding could cause
electric shock.
Do not install the unit in a place where there are explosive gas leaks. Gas
leaks near the unit could cause fire.
Ensure that the drainage piping is connected properly. Otherwise water will
leak out.

4 AIR CONDITIONER INSTALLATION
CHOOSING THE INSTALLATION LOCATION
When installing, use the nearest power outlet. Make sure the power outlet is
easy to reach so you can quickly disconnect your air conditioner in case of
emergency. Ensure that the air conditioner is well supported, securely
fastened, easily reachable and not obstructed. Aviod location with: salty or
sulphurous air, draughts, dampness and flammable gas. If you install the
drainage system, be sure to channel the concensed water to a suitable
location. Covers, obstructions and unsteady support may cause excessive
operating noise and vibration. The rear end of the air conditioner is splash
proof. You don’t need to shield or cover it. R32 refrigerant air conditioner
installation and maintenance should be done by competent person.
PREPARATIONS BEFORE INSTALLATION
Dimension
There should not be any obstacles surrounding the unit.
Prepare and installation hole slightly bigger than the cabinet size.
Left and right side of the unit should be at least 15 cm
away from the wall.
The minimum installation height is 75cm.
(Based on IEC 60335-2-40, there is no restriction for the minimum installation
indoor
floor area since the refrigerant charges is less than 1.224kg.
CAUTION POINT DURING INSTALLATION
When installing air conditioner at glass window or thin partition, fix the vertical and side supporting bar to the concrete wall in order to support the weight of the air-conditioner and reduce the vibration that is being transferred to the glass window or thin partition.
Over100cm
80cm outdoor
This can minimize the noise problem caused by improper installation.
Proposed to use 1/8″ x 1-1/4″ “angle-aluminium for installation frame and side
supporting bar.

ELECTRIC WORK
Always use at the rated voltage and with a specific air conditioning circuit.
This equipment must be earthed and strongly recommended to be installed with
Earth Leakage Circuit Breaker (ELCB) or Residual Current Device (RCD).
Otherwise, it may cause electric shock or fire in case of malfunction. Time
delay fuse or circuit breaker rating is 16 Ampere for CW-XN1821EAi20 Ampere
for CW-XN2421EA Nominal cross sectional area of power supply wire must be 3
core x 2.5 mm2 or above. The power supply must be from an independent circuit.
All electrical installations must be made in accordance with local wiring and
safety regulation wherever applicable. There must be a double pole switch with
a minimum of 3.5 mm contact gap in the fixed installation circuit. Please
engage and authorized dealer or specialist for the installation work.
CONDENSED WATER DRAINAGE
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.

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.

6 HELPFUL INFORMATION & ENERGY SAVING HINTS
HELPFUL INFORMATION Auto Restart Control
Operation will automatically resume under the previous operation mode. If the
unit was set to TIMER mode or SLEEP mode, operation will not resume
automatically. Timer Setting When power failure occurs, the timer setting is
cancelled. Once power returns, reset timer.
ENERGY SAVING HINTS
Clean the air filter every 2 weeks. Regular cleaning of the air filter
preserves efficiency. Keeping ventilation set to CLOSE closed keeps cool air
in and hor air out. Avoid direct sunlight and heat For health reason do not
overcool your room. Your air conditioner’ s cooling capacity should match your
room size.
7 CARE AND MAINTENANCE
Clean the cabinet, front grille with mild soap or detergent and lukewarm
water. 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. 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. 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 Center Ltd. for an annual
check. (Annual check is not covered by the 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 deform the panel.)
PRE-SEASON INSPECTION Is the discharged air cold? 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. Are the air intake and outlet
vanes of the indoor and outdoor side obstructed? Are the remote control
batteries weak?
RECOMMENDED INSPECTION 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.,
