PRECAUTIONS DURING INSTALLATION
WARNING
Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit
by yourself.
•
Please ask your sales agent or qualified technician for the installation of
your unit. Water leakage, short circuit or fi re may occur if you install the unit
by yourself.
•
Please use earth line.
Do not place the earth line near water or gas pipes, lightning-conductor, or
the earth line of telephone. Improper installation of earth line may cause
electric shock.
•
CAUTION
A circuit breaker should be installed depending on the mounting site of the
unit. Without a circuit breaker, the danger of electric shock exists.
•
Do not install near location where there is flammable gas. The outdoor unit
may catch fire if flammable gas leaks around it.
•
Please ensure smooth flow of water when installing the drain hose.•

PRECAUTIONS DURING OPERATION
W
A
R
N
I
N
G
The product shall be operated under the manufacturer specification and not
for any other intended use.
•
Do not attempt to operate the unit with wet hands, this could cause fatal accident.•
When operating the unit with burning equipments, regularly ventilate the
room to avoid oxygen insufficiency.
•
Do not direct the cool air coming out from the air-conditioner panel to face
household heating apparatus as this may affect the working of apparatus such as
the electric kettle, oven etc.
•
Please ensure that outdoor mounting frame is always stable, firm and
without defect. If not, the outdoor unit may collapse and cause danger.
•
Do not splash or direct water to the body of the unit when cleaning it as this may
cause short circuit.
•
Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger fin and blocked the evaporation water flow to
drain pan. The water will drop on tangential fan and cause water splashing
out from indoor unit.
•
Please switch off the unit and turn off the circuit breaker during cleaning, the high-
speed fan inside the unit may cause danger.
•
Turn off the circuit breaker if the unit is not to be operated for a long period.•
Do not climb on the outdoor unit or put objects on it.•
Do not put water container (like vase) on the indoor unit to avoid water
dripping into the unit. Dripping water will damage the insulator inside the unit
and causes short-circuit.
•
Do not place plants directly under the air fl ow as it is bad for the plants.•
When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air defl ector facing down or moving automatically for a long period of time,water
will condense on the air deflector and drips down occasionally. This will wet your furniture.Therefore,
do not operate under such condition for a long time.
If the amount of heat in the room is above the cooling or heating capability of the unit (for example:
more people entering the room, using heating equipments and etc.), the preset room temperature
cannot be achieved.

MAINTENANCE OF THE UNITS
CAUTION
Ensure that the unit is not in operation and all power supply has been disconnected before cleaning the
units.
Dust Filter Screen
Dust filter screens are installed to remove the indoor dust particles hence they should be kept clean at all times.
They should be cleaned at each machine operation cycle of approximately 100 hours. Excessive dust collected at
the dust fi lter screen will block the air fl ow, reduce the cooling capability and could produce noise. Therefore the
dust filter screen should be cleaned as per instructions given below:
Cleaning Instructions
(1) Removing the dust filter screen
•While holding both edges of the front panel, open up and lift the front panel and push in to park at the secured
position
Front panel
Front cabinet
•Slightly lift up the dust filter screen, release the latch clips [2 places] located at the bottom of the front cabinet
and move the dust filter screen downwards to remove it from the unit
(2) Use a vacuum cleaner to vacuum clean the dust accumulated at the dust filter screen. If the accumulated dust
is too much to be removed by vacuum cleaning, apply mild detergent and fl ush the dust from the dust fi lter
screen with water. After thorough rinsing, leave the dust filter screen at a cool shaded place to dry.
(3) Re-install the dust filter screen to its original position (With “FRONT”marker facing front). Slightly lift up the
opened front panel and close it by returning it to its original position
(4) Each year before using the air conditioner unit, clean the heat exchanger (evaporator) with a fi ne soft brush or
a vacuum cleaner and take care to avoid damaging the evaporator fins
Front panel
Dust filter screen
Latch clip
CAUTION
•Do not use hot water (40°C and above) to rinse the dust filter screen, otherwise the screen will warp and
get distorted. After rinsing, shake the dust fi lter screen to rid off all remaining water droplets and place it at a
cool shaded place to dry. Avoid placing the dust fi lter screen under direct sunlight, otherwise the screen will
warp and get distorted.
Do not operate the air conditioner unit without the dust filter screen installed, otherwise the ingress of dust
into the air conditioner unit will cause breakdowns.

AFTER SALE SETVICE AND WARRANTY
WHEN ASKING FOR SERVICE, CHECKTHE FOLLOWING POINTS.
CONDITION CHECK THE FOLLOWING POINTS
When it does not operate
•Is the fuse all right?
•Is the voltage extremely high or low?
•Is the circuit breaker “ON”?
When it does not cool well
•Is the air fi lter blocked with dust?
•Does sunlight fall directly on the outdoor unit?
•Is the air fl ow of the outdoor unit obstructed?
•
Are the doors or windows opened, or is there any source of heat
in the room?
•Is the set temperature suitable?
Notes
•In quiet or stop operation, the following phenomena may occassionally occur,
but they are not abnormal for the operation.
(1) Slight fl owing 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 fi lter 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.
•Power supply shall be connected at the rated voltage, otherwise the unit will be broken or could not reach the
specified capacity.
