Essential instructions for the safety of persons and the environment
•
Refer to the safety instructions for the installation. Failure to comply with these
instructions can result in damages to the system, severe injuries or death.
•
Hot water can burn! ACV recommends using a pre-set thermostatic mixing
valve in order to provide hot water at a maximum of 60°C.
Essential instructions for the correct operation of the system
•
The filling circuit of the DHW tank must be equipped with a safety group,
comprised at least of a stop valve, a check valve, a safety valve set at 7 bar, and
possibly, an expansion vessel of the appropriate size. Make sure that the circuit
between the tank and the safety valve is always open.
•
The third DHW tank connection, if any, can be used for the auxiliary DHW loop. If the
connection is not used, replace the protective plug by a brass plug of the appropriate
size.
General remarks
•
In certain countries the domestic kits must be approved.
•
The circuit illustrations are basic principle diagrams only.

Installation
If there is a risk of low pressure in
the hot water circuit (installation of
the tank on the roof of a building),
it is essential to install a vacuum
breaker device onto the cold water
supply.
