Step 2 Performing the gas leak test
To identify potential gas leaks on the indoor unit, inspect
the connection area of each refrigerant pipe using a leak
detector for R-410A.
Before recreating the vacuum and recirculating the
refrigerant gas, pressurize the whole system with
nitrogen (using a cylinder with a pressure reducer) at a
pressure above 4.1 MPa in order to immediately detect
leaks on the refrigerant fittings.

Step 3 Insulating the refrigerant pipes
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.
No gap
NBR (T13.0 or thicker)
NOTE
Always make the seam of pipes face upwards.
2 Wind insulating tape around the pipes and drain hose
avoiding compressing 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.
