Regumaq X-45
Mounting
•
The supply pipe "storage cylinder circuit
supply" for the fresh water station may only
be connected to one connection pipe of the
buffer storage cylinder (principle of hydronic
decoupling). A joint connection with other
components of the heating system (e.g. by
means of a T-piece) is not permitted.
•
Note the nominal widths for the spanners to
be used, which are embedded in the lower
shell.
•
We recommend the installation of a strainer
in the storage cylinder circuit supply.
•
If necessary, mount another potable water
fi lter (TF) (Oventrop accessory) as close as
possible to the cold water connection of the
station.
•
If a circulation pipe is used, install a strainer
suitable for potable water in the inlet of the
circulation set, if necessary, so that any
particles and foreign bodies do not get into
the measuring turbine.
•
Install a backfl ow preventer(position
3 on page 14) in the cold potable water
supply (position
separate the cold potable water from the
already heated potable water within the
station.
•
When operating the fresh water station with
Oventrop buffer storage cylinders of the
"Hydrocor HP" series, connect the "storage
cylinder circuit supply" to the connection pipe
marked with an arrow in Fig. 17 and FigFig. 18.
•
Install an air vent on the upper dished bottom
of the storage cylinder.
•
If you operate the station in circulation mode,
the water in the circulation circuit expands
when the temperature increases and the
station's safety valve is triggered. Install a
diaphragm expansion tank suitable for
potable water to prevent overpressure in the
circulation circuit.
