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

Heating in winter (Only for heat unit)
In cold winter, Air conditioner can heat up room air.

Dehumidifying in rainy or humid season
Without reducing the room temp., 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.

COOL mode operation
Outdoor temperature should be in range of 18 to 43 , otherwise it is possible for air conditioner to breakdown. Room humidity should be lower than 90%. Otherwise, it is possible for air conditioner to dew at air conditioner surface and even drop water af-ter running for so much time. But this is normal.
DRY mode operation
Outdoor temperature should be in range of 18 to 43 , otherwise it is possible for air conditioner to breakdown.

Power requirement

Rated voltage and voltage range: 220V 10%

The electric components will be damaged when the voltage is too high. If the voltage is too low, the compressor will vibrate violently to dam-age 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 electricity leakage protection switch of enough power capacity and air switch with enough space.

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

Water pipe

Installation procedure:

Remove the sticker from the front panel.
Put the unit into the installation hole.
- When installing the unit, it should be slanted down to the back to avoid the enlargement of noise or vibration. (Slant between 6-10mm.)(Shown at right figure.)
- The installation place should be strong enough to avoid the enlargement of noise or vibration.

Main switch operation procedure (Applicable to Mechanical Models ONLY)

Main Control Knob
Set to Low Cool, Med Cool or High Cool as desired (FAN setting operates the fan only.)
CAUTION:
If the main control knob is turned off changed to a fan setting from a cooling operation setting, WAIT at teast 3 minutes before resetting to cooling operation.
Thermostat control Knob

Operation Tips

Operation for comfort and economy
Do not overcool the room temperature. This is not good for health and wastes electricity.
Keep blind or curtains closed. Do not let sunshine enter the room directly when the air condition is in operation.

Keep the room temp. 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 re-duce 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 pre-vent the heat/cool leakage.
Caution
Operations for safety and health
1) The plug must be accessible after the appliance is positioned.
2) Do not use this appliance in the laundry.
3) If the power cord is damaged, it must be replaced by the manufacture 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 tempera-ture 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 air flow for long periods. This is not recommended for health reason.
Always wait at least 3 minutes before switching the air conditioner on again after you have switched it off during cooling or heating.

Care and maintenance

Always turn off the air conditioner and main power supply before cleaning to ensure safety.
Cleaning unit

Cut power off before cleaning.
Use soft cloth when cleaning cabinet. If the cabinet is very dirty, dip cloth into warm water below 40 dry the cloth and then rub off the dirt.
Don’t use gas, benzene, solvent, wash, chemical solvent, etc. for cleaning.
Do not splash water directly into indoor unit, in which there are micro-computer and circuit plate, they must not be drenched with water.

Check earth wire

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:
1. To remove the air intake grille, grasp the tab on the filter and pull to take out.

2. Vacuum the filter on the dusty side to remove light dust.
3. Wash the filter, cleaner side up under gently flowing water to wash out accumulated dust and lint.

4. If the filter is very dirty, use a mild household detergent in the wash water.
Let the filter dry thoroughly before reinstalling it. If. necessary, please ask the professional personnel to clean it.

Check if air inlet and outlet of outdoor unit are blocked or not.

Trouble shooting guide

Please check the following items before asking for repair, it saves your time and money.
Fault phenomenon

Air conditioner dose not operate at all.
Cool or heat efficiency is not good.
Foggy air flows out.
The air conditioner opera-ion is noisy.
It seems that condensation is leaking from air conditioner.
Air conditioner dose not operate for about 3 minutes when restart.

Trouble-shooting

Is there a power failure?
Is the plug out?
Is power fuse or switch off ?
Whether the voltage is too high or too low?
Is air inlet or outlet locking?
Is there any other heat/cool source in room?
Are air filters dirty very much?
Is indoor fan speed set at LOW?
Maybe the room is too hot/cool when the unit is started.
At COOL mode operation, sometimes there is foggy air flowing out of indoor unit, this is because the room humid air has been cooling rapidly.
The unit is normal while the indoor outlet is sending out some odor, because the inlet air may be mixed with the smell of furniture and smoke.
For a noise that sounds like water flowing:
This is the sound of freon flowing inside the air conditioner unit.
For a noise that sounds like a shower:
This is the sound of the dehumidifying water being processed inside the air conditioner unit.
Condensation occurs when the airflow from the air conditioner cools the warm room air.
This is to protect the mechanism.
Wait about three minutes and operation will begin.
Immediately stop all operations and plug out, please contact your dealer in the following situations.
Operation starts or stops abnormally;
Power fuse or switch often breaks;
Carelessly splash water or something into air conditioner;
Electrical lines are much hot or lines cover breaks;
Other strange situations.
