Check that the flaring is correct, referring to the 
illustrations below for examples of incorrect flaring.

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.

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.

.

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.

Cut off any excess foam insulation.

Make sure that there are no cracks or waves on the 
bent area.

It would be necessary to double the insulation thickness 
(0.39 inch (10 mm) or more) to prevent condensation 
even on the insulator when if the installed area is warm 
and humid.

Do not use joints or extensions for the pipes 
connecting the indoor and outdoor units. 

  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),

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.
