C1. Conditioning circuit water delivery pipe (1")
C2. Domestic hot water tank water delivery pipe (3/4")
C3. Water return pipe (3/4")
C4. Domestic hot water tank water return pipe (1")
C5.-C6. Refrigerant pipes connections (3/8"G - 5/8"G)
The hydraulic connections must be complete by installing:
• air breather valves in the highest points of the pipes;
• flexible elastic couplings.
• stop valves.
• sieve water filter with 0.4 mm meshes.
• thermally insulate all the components and the hydraulic pipes.
The minimum nominal diameter of the hydraulic connection pipes must be
1".
To allow for maintenance or repair operations, it is essential that each hy-
draulic connection is equipped with the corresponding manual shut-off
valves.

The charts in fig.18-18a-18b show the prevalence of the circulator for each speed of the hydraulic circulator
and the load losses inside the machine from which the residual prevalence at the connections of the machine
must be obtained, expendable on the system.
The circulation of the minimum content of the conditioning system be ensured even if the valves
in the system are closed.
