Qty:1 Air Conditioner Compressor Unmatched models corresponding to the picture, you can send a picture to confirm with us before purchase. Please inquire for the full range of models. Please make sure to clean the pipeline and change the filter before installation in order to protect the service life of the compressor.
I. Inspection
1, check whether the original compressor oil is too dirty, if the oil is too dirty, the system must be cleaned with nitrogen system, must replace the filter drier
2, check whether the compressor operation control AC contactor jammed or poor contact, resulting in the compressor phase operation, if the compressor is damaged coil winding, must be replaced with the same type of AC contactor
3, check and protect the circuit, the normal snow pressure state high and low pressure switch is closed, high pressure limit ≤ 2.2Mpa low pressure ≥ 0.28Mpa, is closed, if the damage to be replaced
4、Check whether the radiator is too dirty, must be cleaned
5、Check the original equipment oil refrigerant pressure, if the leakage of snow seed must be repaired.
Second, construction:
1、Disconnect the power supply
2、Disassemble the compressor and check the old compressor.
3、Nitrogen cleaning system, step by step, remove the filter with nitrogen from the
Radiator inlet blowing into the radiator outlet discharge, and then from the filter inlet blowing into the compressor from the return air pipe discharge, repeated cleaning many times
4、Installation of new compression, new filter welding
5、Pressurize with nitrogen, 20Mpa pressure leakage check for 30 minutes.
(Do not use compressor pressure)
6、Circuit inspection and replacement of damaged parts, check the power supply and control lines
7、Clean the radiator
8、Discharge nitrogen, pumping for 30 minutes.
9, add the same type of refrigerant
10、Electrification debugging, testing the compressor current and voltage.If you need other types of compressor, please contact us. Packing:1pc
Warranty period: 120 days
