Refrigeration System Repair. The refrigerant system must be discharged before any maintenance is
performed on any system component. The following paragraphs (5-3 through 5-9) contain procedures detailing
various aspects of the steps commonly taken to repair the refrigeration system. Do not try to re-use or repair seals
and gaskets. New parts should always be used at assembly. When heating refrigeration piping to debraze or
unsolder connections as well as to solder or braze them, the piping should be protected with a continuous flow of
dry nitrogen to prevent scaling or oxidation of the inside surface. Leak testing and dehydrator replacement are
required after any system component has been removed or replaced. The system must be evacuated before it is
charged, and it must be properly charged to function as designed.
