Installation
- The "storage cylinder circuit supply" for the
fresh water station may only be connected
to a connection pipe for the buffer storage
cylinder in isolation (as per the hydraulic de-
coupling principle). A shared connection with
other components in the heating system (via
T-piece, for example) is not permitted.
- Note the nominal widths in the lower shell for
the spanners to be used.
- We recommend using a strainer in the stor-
age cylinder circuit supply.
- If required, install an additional potable water
fi lter (TF) (Oventrop accessories) as closely
as possible to the cold water connection for
the station.
- When using a circulation pipe, install, if re-
quired, a strainer which is suitable for potable
water in the supply pipe for the circulation
set to ensure no particles or foreign bodies
enter the measuring turbine.
- Install a check valve (Position (4) in Illust. 3
on page 13) in the potable water (hot) sup-
ply (position (9) in Illust. 16 on page 25),
to separate the cold potable water from the
water that has already been heated in the
station.
- When operating the fresh water station with
Oventrop buffer storage cylinders in the
"Hydrocor HP" series, be sure to connect
the "storage cylinder circuit supply" to the
central connection pipe.
- Install a bleeder at the upper torispherical
head of the storage cylinder.
- While the station is running in circulation
operation, the water in the circulation circuit
expands in the event of temperature increas-
es and the station safety valve is activated.
Install an expansion tank that is suitable for
potable water to prevent overpressure in the
circulation circuit.
