Tanks with registers
The registers (heat exchangers) built
into the tank are suitable for connecting
to a water heater at any pressure and
temperature shown on the specification
label of the hot water tank.
Forced circulation through a pump is
required.
When installing a tank with a register,
a shut-off member must be installed in
the flow line to prevent back-heating
into the heating circuit when the central
heating and heat pumps are turned off
or in the case of electrical operation.
Central heating connection
Before being placed into service,
the register must be flushed in order
to remove any soiling (e.g. scale) from
the heating circuit.
! ATTENTION
However, under no circumstances
may the supply and return lines
be blocked, as otherwise the water
in the register will not have room
to expand and there is a risk of
damage to the heat exchanger!
Installation may only be performed
by authorised specialists.
NOTE
Temperature display, temperature
regulation for charging pump
With the installation of third-party control
units it must be ensured that the boiler
temperature cannot exceed 95°C during
operation.
Corrosion protection
The enamelled boiler is protected with
a standard magnesium rod-type anode.
This anode is self-consuming and
therefore must be inspected every 2
years and replaced as necessary (for this
purpose, see DIN 4753). A maintenance-
free external current anode (accessory)
can be installed on some models using a
reducing threaded connector IG 5/4"-IG
3/4" (accessory).
