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.
No gap
NBR[T13.0 (1/2") or thicker]
All refrigerant connection must be accessible, in order to permit
either unit maintenance or removing it completely.
Discharge all the nitrogen to create a vacuum and charge
the system.

Be sure to overlap
the insulation
Must fit tightly against body
without any gap.
