PRECAUTIONS DURING OPERATION

● 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 insuf ciency.

● 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.

● Do not place plants directly under the air  ow as it is bad for the plants.

● Please ensure that outdoor mounting frame is always stable,  rm 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.

● When operating the unit with the door and windows opened, (the room humidity is always above

80%) and with the air de ector facing down or moving automatically for a long period of time,

water will condense on the air de ector 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.

●

This appliance is not intended for use by young children or in rm persons unless they have been

adequately supervised by a responsible person to ensure that they can use the appliance safely.

● Young children should be supervised to ensure that they do not play with the appliance.

● Do not climb on the outdoor unit or put objects on it.

● 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.

● The product shall be operated under the manufacturer speci cation and

not for any other intended use.

● 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 use any aerosol or hair sprays near the indoor unit. This chemical

can adhere on heat exchanger  n and blocked the evaporation water

 ow to drain pan. The water will drop on tangential fan and cause water

splashing out from indoor unit.

CIRCUIT BREAKER

When you do not use the room air conditioner, set the circuit breaker to “OFF”.

HOW TO USE THE AIR CONDITIONER EFFECTIVELY

1. An average room temperature setting is probably the best for you as well as

being economical.

 Excessive cooling or heating is not recommended for health reasons. High electricity

bills may also result.

 Close the curtains or blinds to prevent heat from  owing into or escaping the

room as well as to make more effective use of electricity.

2. At intervals, the doors and windows should be opened to let fresh air in.

Make sure the room is ventilated when operating the air

conditioner at the same time as other heating appliances.

3. Using the timer is recommended before going to sleep or going out.

4. The following must never be used for cleaning the indoor and outdoor units.

 Benzine, thinner and scrub can damage plastic surfaces or coating.

 Hot water above 40°C can shrink the  lter and deform plastic parts.

5. Do not block the air intake and air outlet.

 Do not block the air outlets and intakes of the indoor and outdoor units with

curtains or other obstacles which could degrade air conditioner performance and

cause unit failure.

CAUTION

!

REGULAR INSPECTION

PLEASE CHECK THE FOLLOWING POINTS BY QUALIFIED SERVICE PERSONAL EITHER

EVERY HALF YEARLY OR YEARLY. CONTACT YOUR SALES AGENT OR SERVICE SHOP.

Is the earth line disconnected or broken?

Is the mounting frame seriously affected by rust and is the

outdoor unit tilted or unstable?

Is the plug of power line  rmly plugged into the socket?

(Please ensure no loose contact between them).

AFTER SALE SERVICE AND WARRANTY

WHEN ASKING FOR SERVICE, 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”?

● Was the air  lter cleaned?

● Does sunlight fall directly on the outdoor unit?

● Is the air  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?

CONDITION CHECK THE FOLLOWING POINTS

Notes

● In quiet or stop operation, the following phenomena may occassionally occur,

but they are not abnormal for the operation.

(1) Slight  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

the air  lter and the evaporator regularly must be cleaned 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 speci ed capacity.
