The valve has to be mounted into the cold water pipe DIRECTLY in front of the storage tank, observing
the flow direction marked by an arrow. Before installing the valve, the cold water pipes have to be flushed
thoroughly in order to avoid damage caused by any possible contamination.
The outflow joint has to be placed vertically downwards and the vent button has to be accessible. In the
order of water flow there is the one-way valve, the security valve and the outflow pipe that has to be left
open toward the air.
4.2 If the network pressure exceeds 0.6 MPa even intermittently, a pressure reducing valve must be
installed before the water heater. This pressure reducing valve has to be purchased and mounted by the
customer.
The pressure reducing valve has to be mounted in front of the combined valve.
4.3 Any number of offshoots and mixing faucets can be connected to the storage tank. The backflow of
hot water via the faucet towards the water supply is blocked by a one-way valve. (Not a part of the water
heater).
4.4 The storage tank can be disconnected from the water supply using the closing valve.
5. ELECTRIC CONNECTION
5.1 The storage tank may only be connected to the electricity supply with a permanent connector. It is
forbidden to use a wall plug.
5.2 The mains electricity has to be connected to the storage tank through an all-pole disconnection
device, with a minimum 3 mm separation distance between the open contacts.
5.3 Required cross-section of mains network connection cabling: 1.5 mm
