9.12.1 COMPRESSOR PRESSURIZATION
Compressors are delivered pressurized to a pressure of about 0.3-0.35 bar with dry nitrogen and must be
evacuated before implemented in the system.
We suggest removing the rubber plugs from the connectors of the compressor (keep it in upright position) in
the following sequence: discharge, suction. The rubber plugs should be removed with care to avoid oil loss.
The compressor tubes are sealed with caps to avoid contamination by external air and humidity entering
inside the compressor.
9.12 CONNECTORS
9.12.2 CONNECTORS BRAZING PROCESS
Welders must be trained and qualified technicians and all applicable safety regulations and procedures
must be adopted.
Do not allow the flame from the torch to reach the housing during the brazing
of the compressor connectors in order to avoid overheating, damages and oil
carbonization on the compressor's internal shell wall.
Do not allow the flame from the torch to approach the "hermetic terminal (fusite)”
in order to avoid the cracking of the glass insulating material of the pins and
subsequent refrigerant, oil leaks and short circuits.
To minimize any entry of contaminants and humidity, the compressor should
remain open no more than 3 minutes between the extraction of the tube rubber
plugs and the system tubes brazing.
System components should remain sealed as long as possible before their assembly. The brazing of
the components to the system should be carried out no later than 15 minutes aer their assembling.
We suggest removing the rubber plugs from the connectors of the compressor (keep it in upright position)
in the following sequence: discharge, suction.
