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 R-410A, it’s responsable of installer
to pressurize the whole system with nitrogen (using a cylinder
with pressure reducer) at a pressure above 40 bar (gauge).
LEAK TEST WITH R-410A (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.
Insulation
Once you have checked that there are no leaks in the system, you
can insulate the piping and hose.
1
To avoid condensation problems, place Acrylonitrile Butadien Rubber
separately around each refrigerant pipe.
Always make the seam of pipes face upwards.
