Air-conditioner and Heater

Exhaust the refrigerant of the air-conditioner

Note:

Don't exhaust the refrigerant directly, otherwise it

will destroy the ozonosphere. Please take use of the
reclaim device of the refrigerant when exhausting.

Do remember wear the blinkers.

Avoid to touch the refrigerant directly.

Keep the refrigerant container under 40 ℃ and avoid

to drop from high.

Work in a drafty environment, because the vaporiz-

ing of the refrigerant will consume a lot oxygen and cause
dyspnea.

The refrigerant should avoid the fire, because its

combustion will produce toxic gas.

The temperature can't be higher than 40 ℃  too much

when fill the refrigerant.

Don't warm the refrigerant container with the fire, because it may cause the container exploded.

Note：
Don't wash the surface of the condensor and evaporator with vapor. Please use the cold water or compressed

air.

Don't wash the contaminative air-conditioning pipe with compressed air. If the pipe has too much water or

dirt, change it. Don't use your mouth to blow the pipe with refrigerant. 

Don't use the compound gauge with biggish error.
Don't screw down the filler bonnet too much.
Use the refrigerant reclaim device according to the instructions of the factory.

Remove and Install the Air-conditioner

Note：
Make sure that the pressure of the air-conditioning system is lower than the air pressure, then gradually

loosen the exhaust pipe and remove it.

Change and clean the component of the air-conditioner

1.Don't put the compressor sideward or convert it for more than 10 minutes, otherwise, the oil of the compressor

will flow into the low-pressure chamber.

2.Use a  torque spanner and an engineer's spanner at the same time when connect the pipe. 

3.Plug the hole after remove the pipe to avoid the dust and moisture come into.

4.Install the pipe according to the requestment. The sealing plug of the pipe and other component could be

removed when need.

5.Before installing the component in the cold place to the vehicle under the sunshine, please first put the compo-

nent under the sunshine to warm it up. It is necessory for avoiding the moisture emerge on the inner wall of the
component.

6.Get rid of the moisture before filling the refrigerant.

7.The O-sealing ring should be changed.

8.Lubricating as the figure showed when install the pipe, and don't put the lubricating oil on the screw thread.

9.The O-ring should be put about on the seat of the pipe.

10.Insert the guide pipe into the screw pipe fitting, then screw down follow the required torque.

11.After connecting the pipe, make sure there is not any leakage. If there is , dismantle the leaky part of the pipe,

and change the O-sealing ring, then screw down.

The Maintenance of the Compressor

Note:

1.Plug the inlet and outlet of the compressor to avoid the leakage and dirt.

2.Don't put the compesso sideward or revert it for more than 10 minutes.

3.Do remember to discharge the oil of the compressor and check its capacity when change or maintain the com-

pressor.

4.When change the compressor, first take out the oil of the old compressor, then fill the new compressor according

to the required capacity or the capacity of the old compressor.

5.After the maintenance of the compressor, take the shaft of the compressor with your hand to turn for 5 times to

make the oil in the comprssor well-distributed, then run the compressor under the condition that the engine is
idling for 1 hour.

6.When change the electomagnetic clutch, please check if it is working normally under the power supplied.

The Using of the Air-conditioner and Heater

Control panel

Fan switch：

It is used to control the on-off and rotate speed of the bloer.Airflow

Operating-mode chosen switch：

It is used to control the directions of the airflow.

Temperature slide switch：

It is used to adjust the tmperature of the outlet.

Ventilating slide switch：

It is used to introduce the external air.

It is used to circulate the  internal air.

Air-conditioner swich：

Start the engine, put the fan switch at your wanted place, then press the air-conditioner  switch. The indicator

light will go on when the air-conditioner is working. Press again the air-conditioner switch to stop it.

The air-conditioning system only works under the condition of the running of the engine.
