• A pump;
• A 3-way manual valve. This valve
can be motorised if required;
• Connection pipes that can be
used to connect a second heating
circuit;
• Two isolating valves;
• Connectors for the right or left
hand mounting of the expansion
vessel, the safety valve with
pressure gauge and the filling
valve. The expansion vessel is
not included.
Typical single circuit configuration
Drain
The drain cock and safety valve must be connected to the building
drain.

imPOrTanT
As a safety measure, we strongly advise the
installation of a thermostatic mixer to prevent
any risk of burning to persons.
INSTALLATIoN
heating connection
ACV water kit
ACV can supply an optional pre-assembled water kit.
This kit comprises:
domestic hot Water connection
Pressure reducing valve
If the mains water pressure exceeds 6 bar, a pressure reducing
valve calibrated to 4.5 bar must be installed.
Safety group
The safety group of the water tank must be approved by ACV
and calibrated to 7 bar; the group's valve discharge must be
connected to the drain.
Hot water expansion vessel
Installing a hot water expansion vessel will prevent any risk of
excess pressure due to water hammer or pressure fluctuations.
Hot water circulation
If the water tank is a long way from the point of use, installing a
closed recirculation circuit can ensure a faster hot water drawoff
at any time.
