Installation
Turning the connections for the secondary side
If required, the connections (flow and return) for the
secondary side can also be guided out of the top of the
heat transfer station. See the following illustrations for
this. Seals must be attached to all screw joints.

Installing outlet pipes for the safety valve
A safety valve with 3 bar opening pressure has already
been installed for the secondary circuit at the factory.
The outlet is already guided to the bottom of the heat
transfer station in a pipe. Connect the safety valve
outlet to this pipe.

DANGER!
Safety valve outlet
The safety valve outlet must be directed to the ground
in a pipe so nobody is endangered when hot water or
steam is drained.
The safety valve outlet must be fed to the sewage
system (e.g. duct) via a clearly visible, open route
(siphon funnel). This will ensure that malfunctions,
especially a failure of the safety valve to close, can
be detected. If no connection is available to the
sewage system, the outlet must be directed to the
ground in a pipe.
