The Refrigerant

To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The used refrigerant is the fluoride R32, wich is specially cleansed.
The refrigerant is flammable and inodorous. Furthermore, it can lead to an explosion under certain conditions. But the flammability of the refrigerant is very low. It can be ignited only by fire.

Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The influence of the greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a really high energy efficiency. The units therefore need less filling.

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 residences, shops, hotels, offices, libraries and laboratories, and so on.

Cooling in summer

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

Dehumidifying in rainy or humid season

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

Heating in winter
(Only for heat unit)

In cold winter, Air conditioners can heat up room air.

Power requirement

Rated voltage: 220-240V~ 50Hz

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.

Special socket must be used. Furthermore, the socket and wiring must conform to the wiring regulations. And the earthing method must be reliable.
In fixed circuit, there must be an electricity leakage protection switch of enough power capacity and air switch with enough space.

Earth wire

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

Operation Tips

Operation for comfort and economy

Do not overcook 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 temperature uniform. Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room. Air can’t be discharged to the direction of air-in.

Make sure that the doors and windows are tightly closed. Avoid opening doors and windows as much as possible to keep air conditioning in the room.
Clean the air filter regularly.
Blockages in the air filter reduce dehumidifying effects.
Clear 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 the heat/cool leakage.

Caution
Operations for safety and health

The plug must be accessible after the appliance is positioned.
Do not use this appliance in the laundry.
If the power cord is damaged, it must be replaced by the manufacturer or its service agent in void of hazard.

Do not pull out the power cord.

Damage to the cord may result in serious electric shocks
Do not use the air conditioner for other purposes except for cooling the room.
Do not use the air conditioner for other purposes such as drying clothes, preserving foods, or cultivating vegetables
Do not block the air intake and outlet vents.
This causes lowered performance and irregular operation.
Do not insert sticks or other objects into these vents as it is dangerous to touch the electric components and the fan.

Select the most appropriate temperature. Pay attention to adjust the temperature to suit the conditions. Rooms occupied by infants,the elderly, or the sick should be kept at an appropriate temperature.
Do not use heating apparatuses in the vicinity. The air conditioner’s plastic parts will melt if exposed to excessive heat.
Avoid exposing the body directly to a continuous unidirectional airflow for long periods.
This is not recommended for health reasons.

Always wait at least 3 minutes before switching the air conditioner on again after you have switched it off during cooling or heating.

Please notice that the unit is filled with flammable gas R32.
Inappropriate treatment of the unit involves the risk of severe damages of people and materials. Details to this refrigerant are found inthe chapter “Refrigerant”.
The appliance shall be installed, operated and stored in a room with a floor area larger than 4m2.

Care and maintenance

Don’t use gas, benzene, solvent, wash, chemical solvent, etc. for cleaning.
Do not splash water directly into the unit, in which there are micro-computer and circuit plate, they must not be bedrenched with water.

Air filter
The air filter behind the intake grille should be washed at least once every two weeks or as often as it needs cleaning.
How to clean the air filter

To remove the air intake grille, grasp the tab on the filter and pull it out.
