safety component
The safety component for the heating circuit is in the ex-
tra box.
Proceed as follows:
Mount the safety component on the connection
provided on the top of the unit.…
The safety drain of the safety valve must lead into
the drain via a funnel siphon in accordance with the
applicable standards and regulations.
expansion vessels
The expansion vessel of the heat source is included in
delivery and must be installed with the connection as-
sembly.
The expansion vessel for the heating circuit, the corre-
sponding cap valve and the wall mount are included in
the scope of delivery. They must be integrated in the
heating circuit on-site in compliance with the applicable
standards and directives.
We recommend installing a suitable expansion vessel
(not included in delivery) in the hot water circuit. This
equalizes pressure uctuations or water shocks in the
cold water network and prevents unnecessary loss of
water.
