Ø19.05 100 to 120
(1 N•m=10kgf•cm)
NOTE
• If the pipes must be shortened, see Step 6 Cutting and flaring the pipes on page 11.
2 Be sure to use an insulator thick enough to cover the
refrigerant tube to protect the condensate water on the outside of the pipe falling onto the floor and to improve the efficiency of the unit.
3 Cut off any excess foam insulation. 4 Make sure that there are no cracks or waves on the
bent area.
5 It would be necessary to double the insulation
thickness (10 mm or more) to prevent condensation even on the insulator when if the installed area is warm and humid.
6 Do not use joints or extensions for the pipes
connecting the indoor and outdoor units. The only permitted connections are those for which the units are designed.
CAUTION
• Connect the indoor and outdoor units using pipes with flared connections (not supplied). For the lines, use insulated, unwelded, degreased and deoxidized copper pipe (Cu DHP type to ISO 1337 or UNI EN 12735-
1), suitable for operating pressures of at least 4.2 MPa and for a burst pressure of at least 20.7 MPa. Copper pipe for hydro-sanitary applications is completely unsuitable.
• For sizing and limits (height difference, line length, max. bends, refrigerant charge, etc.) see the outdoor unit installation manual.
• All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it completely.
• If the pipes require brazing, make sure that oxygen free nitrogen (OFN) is flowing through the system.
• Nitrogen blowing pressure range is 0.02 to 0.05 MPa.

Installation Procedure
Step 8 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.
Made vacuum for 15 minutes and pressurizing system with nitrogen.

Step 9 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.
