TEMPORARY SWITCH

Use the temporary switch for start or stop operation when operation cannot be done with the remote controller.

By pressing the temporary switch, [use non-conductor stick (for example: toothpick),] the operation will follow previous operation mode.

When the operation is done using the temporary switch, after the power source is turned off and is turned on again, the operation is done in automatic mode.

AIR DEFLECTORS

Vertical de ectors at both sides of outlets can be set to either auto-swing or static position to direct discharge air rightward, leftward or forward direction.

Horizontal de ectors at both sides of the outlets can be set to direct discharge air upward, downward or forward direction.

VERTICAL DEFLECTORS HORIZONTAL DEFLECTORS

To avoid dew forming on the de ectors which eventually may drip to the  oor, please do not adjust horizontal de ectors extremely downward position or vertical de ectors extremely leftward or rightward position during cool operation for a long time. Also, do not adjust the vertical de ectors position by hand or any other object.

CAUTIONS

AIR EXHAUST LEVER

AIR PURIFYING FILTER

Set the air exhaust lever to the down ( OPEN) position for air ventilation in the room. The air exhaust lever should normally be kept in up (

CLOSE)

position during cooling operation and in the case of typhoon.

NOTES ON OPERATION

TEMPERATURE AND HUMIDITY

Avoid to use the room air conditioner for cooling operation when the outside temperature is below 21°C (70°F). Recommended operation humidity should be below 80%. Continuous operation at over 80% humidity (indoor) will cause some dews form on the outlet grille and de ectors of the unit.

NOISE

In a quiet environment during the starting or stopping the operation, phenomena like  owing sound of refrigerant in the refrigerating cycle and rubbing noise from the fan casing may occasionally occur, but this is normal for the operation. Water will be condensed on the evaporator coil and collected in the bottom tray, it is picked up by the condenser fan and blown onto the condenser coil, this creates a “splashing” sound which is normal.

ODOR

The odor will possibly be emitted from the room air conditioner especially at the starting of operation and in a high humidity condition. This is not abnormal phenomena because of the various kind of odors emitted by smoke, food stuffs, cosmetics and others which may stick to the room air conditioner. So, the pre- lter and the evaporator regularly must be cleaned to reduce the odor.

THE IDEAL WAYS OF OPERATION

Suitable Room Temperature

Warning

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

Install curtain or blinds

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

Ventilation

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.

Do Not Forget To Clean The Pre-Filter

Dusty pre- lter will reduce the air volume and the cooling ef ciency. To prevent from wasting electric energy, please clean the pre- lter every 20 days.

Please Adjust Suitable Temperature

For Baby And Children

Please pay attention to the room temperature and air  ow direction when operating the unit for baby, children and old people who have dif culty in movement.

FOR USER’S INFORMATION

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.

When Lightning Occurs

Warning

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