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.
