The “Caution” section contains matters which may result in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.

●

The sign indicate the following meanings.

!

Make sure to connect earth line.

Indicates the instructions that must be followed.

●

Please keep this manual after reading.

PRECAUTIONS DURING INSTALLATION

●

Do not reconstruct the unit. Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by yourself.

●

!

WARNING

!

CAUTION

Please ask your sales agent or qualified technician for the installation of your unit. Water leakage, short circuit or fire 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.

●

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.

and turn off the circuit breaker. Contact your agent. Fault, short circuit or fire 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 fire.

●

Please contact your agent if you need to remove and reinstall the unit. Electric shock or fire may occur if you remove and reinstall the unit yourself improperly.

PRECAUTIONS DURING OPERATION

●

Avoid an extended period of direct air flow for your health.

●

Do not insert a finger, 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.

●

During thunder storm, disconnect and turn off the circuit breaker.

●

This unit has UV LED which emits ultra violet light. AVOID DIRECT EYE EXPOSURE.

!

PRECAUTIONS DURING OPERATION

●

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.

ENGLISH

●

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.

C A U

●

Please switch off the unit and turn off the circuit breaker during cleaning, the high-speed fan inside the unit may cause danger.

T

I

O

●

Turn off the circuit breaker if the unit is not to be operated for a long period.

N

●

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 flow 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 deflector 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.

●

This appliance is not intended for use by young children or infirm 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.

Warning

Freezing temperature is bad for health and a waste of electric power.

It is possible to reduce heat entering the room through windows.

Ventilation Effective Usage Of Timer

!

Caution

Do not close the room for a long period of time. Occasionally open the door and windows to allow the entrance of fresh air.

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.

ENGLISH

Do Not Forget To Clean The Air Filter

Dusty air filter will reduce the air volume and the cooling efficiency. To prevent from wasting electric energy, please clean the filter every 2 weeks.

Please Adjust Suitable Temperature

For Baby And Children

Please pay attention to the room temperature

and air flow direction when operating the unit

for baby, children and old folks who have

difficulty in movement.

FOR USER’S INFORMATION

Inverter-type fluorescent lamp.

To prevent interference, place at least 1m away.

TV

The Air Conditioner And The Heat Source In The Room

!

Caution

If the amount of heat in the room is above the cooling capability of the air conditioner (for example: more people entering the room, using heating equipments and etc.), the preset room temperature cannot be achieved.

Not Operating For A Long Time

When the indoor unit is not to be used for a long period of time, please switch off the power from the mains. If the power from mains remains “ON”, the indoor unit still consumes about 8W in the operation control circuit even if it is in “OFF” mode.

OFF

When Lightning Occurs

!

Warning

To protect the whole unit during lightning, please stop operating the unit and remove the plug from the socket.

UV-LED

UV-LED will be “ON” when the START/STOP button is pressed except for FAN only operation. During selected operation, this UV-LED will be “ON” and “OFF”. Light UV glare is visible when the UV-LED is “ON” and this is normal (not malfunction).

Interference From Electrical Products

MAINTENANCE

!

CAUTION

Cleaning and maintenance must be carried out only by qualified service personal. Before cleaning,

stop operation and switch off the power supply.

1. AIR FILTER

Clean the air filter, as it removes dust inside the room. In case the air filter is full of dust, the air flow will decrease and the cooling capacity will be reduced. Further, noise may occur. Be sure to clean the filter following the procedure below.

PROCEDURE

Open the front panel and remove the filter

● Gently lift and remove the air cleansing filter

from the air filter frame.

Vacuum dust from the air filter and air cleansing filter using vacuum cleaner. If there is too much dust, air filter only rinse under running tap water and gently brush it with soft bristle brush. Allow filters to dry in shade.

● Re-insert the air cleansing filter to the filter

frame. Set the filter with “FRONT” mark facing front, and slot them into the original state.

● After attaching the filters, push the front panel

at three arrow portions as shown in figure and close it.

NOTE:

● Air cleansing filter should be cleaned every month or sooner if noticeable loading occurs. When

used overtime, it may loose its deodorizing function. For maximum performance, it is recommended to replace it every 3-6 months depending on application requirements.

!

CAUTION

● Do not wash with hot water at more than 40°C. The filter may shrink.

● When washing it, shake off moisture completely and dry it in the shade; do not expose it directly to

the sun. The filter may shrink.

● Do not use detergent on the air cleansing filter as some detergent may deteriorate the filter

electrostatic performance.

2. Washable Front Panel

● Remove the front panel and wash with clean

water. Wash it with a soft sponge. After using neutral detergent, wash thoroughly with clean water.

● When front panel is not removed, wipe it with

a soft dry cloth. Wipe the remote controller thoroughly with a soft dry cloth.

● Wipe the water thoroughly.

If water remains at indicators or signal receiver of indoor unit, it causes trouble.
