Installation

The buffer tank must be mounted and installed by an authorised
specialist company!
The buffer tank must be installed in a frost-free location. The pipe
runs to the heat generator must be kept as short as possible.
The operating overpressures indicated on the type plate must not
be exceeded. Electric heating elements (immersion heaters)
must only be connected by authorised electricians according to
the corresponding circuit diagram. All relevant requirements of
the utility company, the Association of German Engineers (VDE)
and DIN 4751-2 must be observed.
NOTE
The buffer tanks are not enamelled and, for this reason, must never be
used for heating water for domestic use.
NOTE
All connections lead out from the buffer tank and are flush to the
insulation. If a connecting stub is not in use, it should be sealed using a
cap or sealing plug.
NOTE
During the cold months, the thermal insulation of the buffer tank must be
stored at room temperature before installation in order to avoid damage
to the insulation and fastening mechanism.
NOTE
A means of draining the tank should be provided on the lower stub (base
of the buffer tank).
GB-2

1.1 Safety valve

If the buffer tank is fitted with one or more immersion heaters, it
must additionally be equipped with a type-tested diaphragm
safety valve which cannot be shut off.
The connection diameter must have a nominal width (NW) of at
least 20. The air outlet pipe must not allow any pressure increase
to take place.
The operational reliability of the safety valve must be checked at
regular intervals.

1.2 Start-up

Ensure that the water supply is turned on and the buffer tank is
filled before start-up.
The initial filling and start-up must be carried out by an authorised
specialist company.
The entire system, including all assembled components, must be
inspected to ensure that everything is working properly and that
there is no leakage.
The electric heating element (if present) should be de-scaled and
tested anually (or more frequently in hard water areas).
NOTE
The thermal insulation supplied with the buffer tank is only suitable for
heating purposes.
If the tank is to be used for cooling purposes, it must be fitted with steam-
resistant insulation (to be provided by the customer). This must include
all heating connections (also including the sleeves for the immersion
heaters) in order to prevent condensate from forming on the buffer tank
during cooling operation.
