INSTALLATION
Connection to the system
To make the connections:
– hydraulic lines positioning
– use the "wrench against wrench" method
– tighten the connections
– check for leaks
– coat the connections with insulating material
The hydraulic lines and fittings must be thermally insulat-
ed.
Avoid partial insulation of the pipes.
Avoid over-tightening the pipes to avoid damage to the
insulation.
Carefully check that the insulation is tight, in order to pre-
vent the making and dripping of condensate.
Hydraulic accessories

In other case, depending of the request, the unit can be sup-
plied with valves already assembled or supplied separately
to be mounted during installation.
The 2-way and 3-way motorized valves are mandatory for
the correct operation of the unit.
The motorized valve can be omitted, inside the unit, if
there is a motorized valve in the distribution manifold of
the system and connected to the regulation card of the
unit.
