CONNECTION OF THERMODYNAMIC GROUP AND PANEL
Some of the steps are the repetition of the steps carried out for the connection to the panel.
Cut the required measure of the pipe with the edge turned upside down. Sand any remaining rough edges.
Shape a conic edge in the pipe and do not forget to place the female coupling on the side of the pipe.
Tighten the female coupling with your hand, giving it a few turns, and secure with wrench applying the
torque as before.
NOTE: Every coupling must be insulated

NITROGEN LOAD
a)
After finishing the couplings, make sure there are no leaks. For this purpose, inject a load of nitrogen
with a pressure of 10 bar through the pressure inlet (3-way valve).
b)
Brush every coupling in soap foam and make sure that the pressure in the pressure gauge is
constant.
