Step 7 Connecting the assembly pipes to the refrigerant pipes

There are two refrigerant pipes of different diameters :

• A smaller one for the liquid refrigerant.

• A larger one for the gas refrigerant. The inside of copper

pipe must be clean and has no dust.

1 Remove the pinch pipe on the pipes and connect the

assembly pipes to each pipe, tightening the nuts, first manually and then with a torque wrench, a spanner applying the following torque.

Ø9.52 34 to 42

Ø12.70 49 to 61

Ø15.88 68 to 82

Ø19.05 100 to 120

NOTE

• If the pipes must be shortened, see Step 6 Cutting and flaring the pipes on page 10.

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.

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.
