6.2.4 ELECTRICAL FAULT
Electrical faults can be judged by a noticeable pungent odor. In the event of a severe burn, the oil will
turn black and acidic. In the event of electrical failure and the refrigeration compressor motor is
completely burned out, measures must be taken to clean the system to eliminate acid in the system and
to prevent such failures in the system.
NOTE:
Damage of compressor replacement parts which caused by improper cleaning, according to
the applicable warranty is not binding.
When the compressor is completely burned, replace the compressor and replace the filter,
and check the throttling components. If there is a fault, it should be replaced. Before the
replacement, the cleaning system is necessary. If the cleaning method is not clear, please
consult our professional and technical personnel.
6.2.5 PROCEDURE FOR REPLACING THE COMPRESSOR
Cut off the power;
Connect the interface of the pressure gauge to the needle valve on the suction pipe for refrigerant recovery;
NOTE:
The refrigerant must be recycled or disposed of in accordance with relevant regulations. The
release of refrigerant into the atmosphere is harmful to the environment and is illegal.
1. Remove the electrical connection to the compressor;
2. Loosen the nozzle on the suction and exhaust ports of the compressor;
3. Remove the faulty compressor;
4. If the compressor is completely burned, the refrigeration system piping should be cleaned and
the filter should be replaced;
NOTE:
The new compressor should not unplug the rubber plug of the suction and exhaust ports too
early. The compressor without plug in the air should no more than 15 minutes to prevent the
compressor from absorbing water and bringing it to the system.
5. Install the new compressor in place and connect the pipe nozzle. Connecting electrical lines;
6. Vacuum the system and add refrigerant; the vacuuming time is more than 60 minutes, and the vacuum should be
kept more than 10 minutes. After ensuring normal of the vacuum, the refrigerant can be added according to the
rating plate parameters.
7. Power on the system according to the normal start up debugging process, and check whether the system running
parameters are normal.
