To identify potential gas leaks on the indoor unit, inspect the connection area of each refrigerant
pipe using a leak detector for R410A.
Before recreating the vacuum and recirculating the refrigerant gas, it is advisable to pressurize the
whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 40 bar in
order to immediately detect leaks on the refrigerant ttings.
Made vacuum for 15 minutes and pressurising system with nitrogen.

Leak test
Performing 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 Acrylonitrile Butadien Rubber separately
around each refrigerant pipe.
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 xed to the wall with suitable ducts.
5 Select the insulation of the refrigerant pipe.
X Insulate the gas side and liquid side pipe referring to the thickness
according to the pipe size.
