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.

G
The product shall be operated under the manufacturer specification and not
for any other intended use.
s
Do not attempt to operate the unit with wet hands, this could cause fatal accident.s
When operating the unit with burning equipments, regularly ventilate the
room to avoid oxygen insufficiency.
s
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.
s
Please ensure that outdoor mounting frame is always stable, firm and
without defect. If not, the outdoor unit may collapse and cause danger.
s
Do not splash or direct water to the body of the unit when cleaning it as this may
cause short circuit.
s
Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger fin and block the evaporation water flow to
drain pan. The water will drop on tangential fan and cause water splashing
out from indoor unit.
s
Please switch off the unit and turn off the circuit breaker during cleaning, the high-
speed fan inside the unit may cause danger.
s
Turn off the circuit breaker if the unit is not to be operated for a long period.s
Do not climb on the outdoor unit or put objects on it.s
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.
s
Do not place plants directly under the air flow as it is bad for the plants.s
When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air deflector facing down or moving automatically for a long period of time,water
will condense on the air deflector and drip 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
unit.
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 filter screen will block the air flow, 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 flush the dust from the dust filter
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 fine 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 (40e
C or above) to rinse the dust filter screen, otherwise the screen will warp and
get distorted. After rinsing, shake the dust filter screen to rid off all remaining water droplets and place it at a
cool shaded place to dry. Avoid placing the dust filter 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.

CLEANING THE FRONT PANEL
Front panel can easily get dirty. Use a soft cloth to wipe it.
If the front panel is excessively dirty, wipe the front panel with a soft
cloth either wet with warm water or containing a mild detergent after
which, wipe dry the front panel with a soft dry cloth.
Do not use hot water (50°C or above), volatile liquid, gasoline,acid,
diluting agents or brushes to clean the front panel as they could
damage the plastic finish and paintwork of the front panel.
