Performing Leak Test & Insulation
g The designs and shape are subject to
change according to the model.
Leak check
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 responsible of installer to pressurize the whole
system with nitrogen (using a pressure regulator) at a pressure above
4.1MPa(594.7 psig) (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 R-410A.
Leak test
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 T13.0 (1/2") or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
Note Always make the seam of pipes face upwards.
2
Wind insulating tape around the pipes and drain hose avoiding to compress
the insulation too much.
3
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.
4
The pipes and electrical cables connecting the indoor unit with the outdoor
unit must be fixed to the wall with suitable ducts.
