!● Do not insert a Þ nger, a rod or other objects into the air outlet or inlet. As the fan is rotating

at a high speed, it will cause injury. Before cleaning, be sure to stop the operation and turn

the breaker OFF.

● Do not use any conductor as fuse wire, this could cause fatal accident.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

● Should abnormal situation arises (like burning smell), please stop operating the unit and turn

off the circuit breaker. Contact your agent. Fault, short circuit or Þ re may occur if you continue

to operate the unit under abnormal situation.

●Please contact your agent for maintenance. Improper self maintenance may cause electric

shock and Þ re.

●Please contact your agent if you need to remove and reinstall the unit. Electric shock or Þ re

may occur if you remove and reinstall the unit yourself improperly.

WARNING

PRECAUTIONS DURING INSTALLATION

● Do not reconstruct the unit.

Water leakage, fault, short circuit or Þ re may occur if you reconstruct the unit by yourself.

● Please ask your sales agent or qualiÞ ed technician for the installation of your unit. Water

leakage, short circuit or Þ 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.

● Be sure to use the speciÞ ed piping set for R410A. Otherwise, this may result in broken

copper pipes or faults.

● 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 ß ammable gas. The outdoor unit may catch

Þ re if ß ammable gas leaks around it.

● Please ensure smooth ß ow of water when installing the drain hose.

● Do not install the indoor unit in a machine shop or kitchen where vapor from oil or its

mist ß ows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing

the indoor unit performance and may deform and in the worst case, break the plastic

parts of the indoor unit.

CAUTION

!

● Spray cans and other combustibles should not be located within a meter of the air outlets

of both indoor and outdoor units.

As a spray can’s internal pressure can be increased by hot air, a rupture may result.

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

can adhere on heat exchanger Þ n and blocked the evaporation water ß ow

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

out from indoor unit.

● Please ensure that outdoor mounting frame is always stable, Þ 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 deß ector facing down or moving automatically for a long period of time,

water will condense on the air deß 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 inÞ 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 speciÞ 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 place plants directly under the air ß ow as it is bad for the plants.

waste of electric power.

It is possible

to reduce

heat entering

the room

through

windows.

At night, please use the “OFF or ON timer

operation mode”, together with your wake

up time in the morning. This will enable you

to enjoy a comfortable room temperature.

Please use the timer effectively.

Please pay attention to the room temperature

and air ß ow direction when operating the unit

Do not close the room for a long period

of time. Occasionally open the door and

windows

to allow the

entrance of

fresh air.

THE IDEAL WAYS OF OPERATION

Do Not Forget To Clean The Pre-Filter

Dusty pre-Þ lter will reduce the air volume

and the cooling efÞ ciency. To prevent from

wasting electric energy, please clean the

pre-Þ lter every 2 weeks.

CONDITION CHECK THE FOLLOWING POINTS

Notes

● In quiet operation or stopping the operation, the following phenomena may

occassionally occur, but they are not abnormal for the operation.

(1) Slight ß 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 pre-Þ 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

speciÞ ed capacity.

When it does not cool well

When it does not hot well

If the remote controller is

not transmitting a signal. ● Do the batteries need replacement?

● Is the polarity of the inserted batteries correct?

Remote controller

display is dim or blank.)

NOTE:

● If the supply cord is damaged, it must be replaced by the special cord obtainable at authorized service

parts centers.

● On switching on the equipment, particularly when the room light is dimmed, a slight brightness ß uctuation

may occur. This is of no consequence.

The conditions of the local Power Supply Companies are to be observed.
