5 Installation instructions
for qualified personnel
General instructions prior to installation
n Ensure that the area in which the unit is to be
operated is free of frost and easily accessible
for required maintenance, repairs and even for
the possible replacement of the unit (e.g. avoid
narrow passageways and doorways).
n When installing the storage tank in non-
standard locations, such as in lofts, residential
units with floors that are sensitive to water,
storerooms, etc., take account of the possibility
of leaking water, and ensure that a facility is in
place to collect the water, including appropriate
drainage methods.
n The unit may only be installed and operated on
level surfaces.
n When planning the unit’s installation surface
and selecting the installation location, note the
total weight of the buffer tanks, including the
weight of the water (the nominal capacity), in
order to ensure that the load-bearing capacity
of the support surface is not exceeded.
n Ensure proper clearance from furnace sys-
tems.
n Make sure that the connection block (water
and electric connections and heater installa-
tion) of units with enclosures, which are
installed in small, confined spaces or in sus-
pended ceilings are still freely accessible and
that there us no build-up of heat.
n Leave at least 500mm of space free for the
removal of the cleaning/heating flange.
Assembly
n Check the contents of the packaging for com-
pleteness and check the unit for visible trans-
port damage. Immediately notify your contract
partner of any deficiencies.
n The storage tank may not be transported with
the fine-tube heat exchanger installed.
n The unit must be assembled on site.
n For all connection ports, ensure that the
threading is fully engaged.
n In the selection and/or sequence of the installa-
tion materials used for the plant, any possible
electrochemical processes must be taken into
consideration in accordance with the recog-
nised good practices (mixed-metal installa-
tions!).
n The potential equalisation of the piping must
take place in accordance with DIN 50927. This
type of corrosion results in the formation of cor-
rosion cells. Voltage is present in corrosion
cells between the anode and cathode area.
The processes are dependent on one another,
however, their separation from one another can
vary greatly. Corrosion cells can appear as a
result of different potentials, as the case is with
contact corrosion. Different metals are in con-
ductive contact with one another through an
ion-conducting medium (water). All metal plug-
in (built-in) components with large metal sur-
faces (e.g. flange heating cartridge, fine-tube
heat exchangers, electric heaters) must be
electrically insulated from the storage tank. For
the protection of the above-mentioned plug-in
(built-in) components against the current-
induced corrosion, we recommend installing a
defined contact resistance of approx. 600 Ohm
(insofar as it has not already been installed in
the components at the factory).
