Function

Introduction

Window type room air conditioners can regulate the room temperature and dry the room. It is convenient for your work, study, and life. It can be widely used in residence, shop, hotel, office, library, and laboratory, and so on.

Cooling in summer

In hot summer, the air conditioner can cool down the room air by transferring heat out.

Dehumidifying in rainy or humid season

Without reducing the room temp., the air conditioner can dehumidify and make the room air dry and comfortable.

Exchange fresh air

Open storm door to keep the fresh air in the room.

Operating Condition

Please operate air conditioner in the correct conditions as following.

Power requirement

The electric components will be damaged when the voltage is too high. If the voltage is too low, the compressor will vibrate violently to damage the refrigerant system and easily cause the compressor and electric components not work.

The ground must be connected. A special socket must be used. Furthermore, the socket and wiring must conform to the wiring regulations. And the earthing method must be reliable.

In a fixed circuit, there must be an electricity leakage protection switch of enough power capacity and an air switch with enough space.

Earth wire

To ensure the reliable earthing, please do not connect earth wire to the following places:

Operation Tips

Operation for comfort and economy

• Do not overcool the room temperature. This is not good for health and wastes electricity.
• Keep blinds or curtains closed. Do not let sunshine enter the room directly when the air conditioner is in operation.
• Keep the room temp. uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room. Air cannot be discharged to the direction of air-in.
• Make sure that the doors and windows are tightly closed. Avoid opening doors and windows frequently to keep air conditioning in the room.
• Clean the air filter regularly. Blockages in the air filter reduce dehumidifying effects. Clean the air filter at least once every two weeks.
• Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them and ventilate the room now and then. When starting the unit, curtains or windows should be closed to prevent heat/cool leakage.
