Performing leak test & insulation
Leak test
LEAK TEST WITH NITROGEN (before opening valves)
In order to detect basic refrigerant leaks, before recreating the vacuum and
recirculating the R410A, it’s responsible of installer to pressurize the whole
system with nitrogen (using a cylinder with pressure reducer) at a pressure above
30 bar (gauge).
LEAK TEST WITH R410A (after opening valves)
Before opening valves, discharge all the nitrogen into the system and
create vacuum. After opening valves check leaks using a leak detector for
refrigerant R410A.
CAUTION
Discharge all the nitrogen to create a vacuum and charge
the system.
Insulation
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
