Air-conditioner and Heater
BF-16
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
