Stop the nitrogen supply when the piping has cooled down.
6
Remove the high pressure switch.
INFORMATION
It is ALSO possible to cut the component pipe(s) using a pipe cutter. Make sure to
remove the remaining component pipe end(s) from the refrigerant pipes by heating
the brazing point(s) of the component pipe(s) using an oxygen acetylene torch.
7
Install a plug or cap on the refrigerant piping to avoid dirt or impurities from
entering the piping.
