Drinking water feed
Connect the drinking water line with the mechanical float valve (3/4“) of the
break tank system
and seal.
Connect the connection line in de-energised state. There should not be any forces applied to the connection
sockets and system. Install a pressure reducer in front of the system if necessary to ensure that no more than 5
bar of primary pressure is fed from the drinking water network. We recommend installing a shut-off valve, a
detachable screw and an external fine water filter.
The feed volumes of the mains water feed must be within the range of the stated flow pressure (see 3.2) to
ensure the long-term reliability of supply of the immersion pressure pump with sufficient water guarantees.
