WARNING

PRECAUTIONS DURING INSTALLATION

●

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 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.

CAUTION

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.

●

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

●

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

●

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

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 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.

●

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 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.

●

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.

●

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.

C A U T

I O N

●

The product shall be operated under the manufacturer specification 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 flow as it is bad for the plants.

●

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.

DEHUMIDIFYING OPERATION

Use the device for dehumidifying when the room temperature is over 16°C. When it is under 15°C, the dehumidifying function will not work.

■ Dehumidifying Function

When the room temperature is higher than the temperature setting: The device will dehumidify the room, reducing the room temperature to the preset level. When the room temperature is lower than the temperature setting: Dehumidifying will be performed at the temperature setting slightly lower than the current room temperature, regardless of the temperature setting. The function will stop (the indoor unit will stop emitting air) as soon as the room temperature becomes lower than the setting temperature.

Set the desired room temperature with the TEMPERATURE button (the display indicates the setting).

The range of 20-26°C is recommended as the room temperature for dehumidifying.

Do Not Forget To Clean The Air Filter

Please Adjust Suitable Temperature

For Baby And Children

Warning

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

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

At night, please use the “sleep 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.

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 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.

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.

CAUTION

Do not bend the air cleansing filter as it may cause damage to the structure.

NOTE

● In case of removing the air cleansing filters, please follow the above procedures.

● The cooling capacity is slightly weakened and the cooling speed becomes slower when the air cleansing

filters are used. So, set the fan speed to "HIGH" when using it in this condition.

● Air cleansing filters are washable and reusable up to 20 times by using vacuum cleaner or water rinse

under running tap water. Type number for this air cleansing filter is <SPX-CFH19>. Please use this number for ordering when you want to renew it.

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.

CAUTION

1

Open the front panel and remove the filter

● Gently lift and remove the air cleansing filter

from the air filter frame.

2

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

3

● 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

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 filter cleaned?

● Does sunlight fall directly on the outdoor unit?

● Is the air flow 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 operation or stopping the operation, the following phenomena

may occassionally occur, but they are not abnormal for the operation. (1) Slight flowing 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 filter 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 specified capacity.
