Air filter cleaning

Before cleaning, turn off the power.

When dirt accumulates on air filter, air circulation will be blocked, which causes poor cooling. It is advisable to clean air filter every two weeks for longer operation.

Take out the air filter

1.Loose the air inlet by pushing “PUSH” at both edges as shown.

2.Open the air inlet.

3.Remove the air filter.

Clean the filter

1.Gently flap the dirt off the air filter.

2.Carefully wash air filter in warm water(below 40°C).To obtain better cleaning effect,soap water or neutral detergent may be used.

CARE AND MAINTENANCE

Always turn off the air conditioner and the main power supply before clean the unit. Switch off the power supply if the unit is not going to be used for a long period of time.

Air filter cleaning

It is advisable to clean air filter every two weeks for longer operation. (You will find how to clean the filter on page 2 .)

Notes

Avoid opening doors and windows unless necessary.

Use curtain or blind Direct sunlight may reduce cooling effect, always use window curtain.

Don't be exposed to cold air for a long time.

Keep heat source away from air conditioner.

Cleaning of the

air filter

Set temp . a little bit higher before going to bed.

Proper temperature

After unit stops, don't restart it until 3 min. have elapsed.

OK! Enjoy a 3-min nap

PREPARATIONS BEFORE INSTALLATION

Make the wall hole or window hole (see Fig.1)

MODEL A B

HW-09CU03 HW-12CU03 HW-09CUA03 HW-12CUA03

HW-18CU03 HW-18CUA03

Prepare unit for installation:

1.Take out the conditioner and accessories from the package .

2.Disposal of the condensed water.

Block the bottom plate hole of the conditioner with rubber lid, install drain elbow on the back hole and let the condensing water flow from the back hole of the conditioner. (See Fig.1 ) In this method, the accumulated condensed water in the bottom plate is hit by the fan onto the heat exchanger, and evaporated and blown out from the machine. It can cool the heat exchanger adiator more quickly, and improve the energy efficiency of the conditioner. But the hitting noise by the fan at the outdoor side is relatively large.

NOTE: For some models your Drain elbow may be the same as Fig.2.

Don't hang clothes in the vicinity of air inlet. This will decrease cooling effect and cause abnormal operation.

AIR CONDITIONER INSTALLATION

Temperature should be set properly when there are infant,child, the aged or disabled in the room.

Baby has gone sleep, better to adjust suitable temp.

Before operating mode selection switch, check that if the air inlet or outlet have been blocked.

(ONLY FOR REFERANCE)

SELECTION OF THE INSTALLATION POSITION

1,The air-conditioner is better installed in shadow or in a place with short period of sunshine. In case the air-conditioner is installed at the point exposed directly to the sunshine, it should be protected from the direct sunlight as possible in order to avoid the long time of direct sunlight otherwise its performance will be lowered. (As illustrated in Fig. 1).

2. For the convenience of operation, it is recommended that air-conditioner be installed at least at the height of 760-1300 mm above the floor and no obstacles before it for a free airflow.

3.The shutters at both sides and the top of air-conditioner should be protruded outdoors free from being blocked by wall, window,ect.

4.The back of air-conditioner should be kept over 500mm from the obstacles (for example, wall, etc.) (As illustrated in Fig. 2).

5.To have an efficient drainage, the back part of the air-conditioner should be inclined downward

>500mm

fig.2

by 5-10mm (As illustrated in Fig. 3).

NOTES:

For longer and trouble-free operation of the unit, pay special attention to the following:

Install air-con at a place strong enough to support the unit. Leave enough space around air inlet and outlet for better circulation. Avoid places where flammable gas leaks. Problems may occur if unit is installed in the following places: Place where oil exists in the air including engine oil or seaside with salt breeze blows and hot spring area with sulphurous gas in the air.

NOTE: When install drain elbow, adjust the direction of the drain elbow to make it be in line with the hole in the rear of unit; Insert the drain elbow into hole and twist 90°.

INSTALLATION PROCEDURES

1. Fix the prefabricated iron frame to stable position by expansible screws.

2. Put the whole machine with all the accessories installed on the iron frame.

If there's water outlet flexible pipe, lead it to needed position(see Fig.1).

3. Fill any distance between the wall hole and the machine body with flexible sponge rubber strip to prevent the entering of outer

noise and the leaking of the coolness.

4. Open the Air inlet geille ,fix the front panel to the chassis

firmly with the accessorial screw.(see Fig.2 or Fig.3) (NOTE:Your model will be the same as one of the right two illustrations,not both.)

5. After installation of the conditioner, insert the power plug into the outlet and perform test-run.

Cautions

Power cord: Be sure to use the exclusive power cord. Change installation place: If air-con need to be changed to another place please contact the dealer, who sold you the unit.
