Connection
The hydraulic connections may be made towards the wall
(concealing them from sight) or upwards. Connect a drain
pipe to water safety valve so as to prevent that some water
leakage can get inside electrical parts.
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
Thehydraulicconnectionsmustbecompletedbyin-
stalling:
• air release valves at the highest points of the piping
•
•
• a suitably sized storage tank for plant water
• the secondary separator kit is available as accessory
•
the appliance on the system front
The separator kit is mandatory unless it is already pres-
ent in the system.
Be careful not to invert delivery and return lines.

inlet of the appliance in an area accessible for
maintenance, in order to protect the appliance
from impurities in the water.
3�12�7 Safety valve
The outlet of the installed safety valve must be connected
to a suitable collection and evacuation system to prevent
any water spillage from coming into contact with the elec-
trical parts of the appliance.
The manufacturer of the appliance is not responsible
valves.
Provide a pressure reducer if the mains pressure ex-
ceeds 3 bar.
3�12�8 Coil vent
To avoid air pockets inside the circuit, place automatic
or manual venting devices at all points (higher piping, si-
phons, etc.) where air can accumulate.
