Notes on safety and use2.0
Enamelled domestic water storage tanks
GB
Documentation2.1 This installation and operation manual is absolutely necessary to read before
commissioning / use of the storage tank!
In addition, it is part of the scope of delivery, has to be handed over to the user
and should always be kept near the place where the storage tank is located.
IMPORTANT: We accept no liability for any damage caused by failure to observe
these instructions.
Regulations2.2 The relevant provisions of DIN, DIN EN, DVGW, VDI, TRF and VDE as well as all local
and country-specific regulations, directives and standards for heating and water heating
systems as well as for drinking water installations must absolutely be adhered to.
If any specifications in this manual are in contradiction to the country-specific provisions,
the latter are preferable.
Work on the storage tank2.3 Installation and commissioning as well as maintenance and repairs must be carried out
by authorised specialists (heating contractor / contract installation company).
The high-efficiency insulation of storage tanks of up to , litres is made of vacuum
panels embedded in a PU foam jacket.
By e.g. pricking, sawing or cutting into the PU foam jacket, the vacuum panels can be
damaged. This must be avoided!
Vacuum panels have a core that is wrapped in foil and made of grey silicate. The silicate
is harmless to health, not ecotoxic and can be disposed of in your household waste. If,
due to external force, silicate may leak, we recommend the use of gloves and a dust mask
despite the silicate being harmless.
Place of installation2.4 The storage tanks may only be installed in frost-protected areas. If there is the risk of
frost, the tank as well as all water-bearing fittings and connection pipes have to be
drained.
The location for installation must be accessible for maintenance and repairs, and it must
be ensured that the ground is level with a sufficient load capacity.
Refer to the manufacturers’ documents for distances to firing installation systems.
According to the Firing Installation Order, the minimum distance to e.g. solid fuel boilers
has to be m as sparks might occur.

Intended use 1.02.5
The enamelled domestic water storage tanks are used for indirect heating, storage and the
supply of drinking water to or respectively in the desired temperature in closed systems.
The heat is transferred by internal heat exchangers, which are flowed through by hot
water (in accordance with VDI ) and / or solar liquid (water / glycol mixtures in
a ratio of up to :.
Optionally, the storage tanks can be equipped with screw-in immersion heaters of
different makes and performances. They have to fulfill the following requirements:
• suitability for use in drinking water systems
• a length assigned to the respective storage tank diameter
• German TÜV- or respectively VDE-tested version
The installation and the electrical connection of the immersion heaters must only be
carried out by qualified personnel and in accordance with the manufacturer’s installation
instructions. The screw-in immersion heaters are subject to the warranty conditions of
the manufacturer.
The cold water connection of the storage tank is attached to the drinking water network,
the hot water connection is attached to the tapping points. If hot water is taken from
a tapping point, cold water flows into the storage tank and is heated to the set
temperature.

All storage tanks may only be used in closed systems. All connections are to be made
pressurised. Connections that are not required must be sealed. In order to minimise
heat losses, all lines should be insulated.
The storage tank is to be installed in such a way that it can be drained without
dismantling.
IMPORTANT: If a smooth-pipe heat exchanger is not required, it has to be sealed to
prevent the ingress of oxygen. Otherwise, due to the formation of condensing water
in conjunction with oxygen, this might lead to corrosion.
IMPORTANT: The smooth-pipe heat exchangers must not be locked on both ends if filled,
because an overpressure might otherwise occur.
IMPORTANT: Before commissioning / heating the storage tank via smooth-pipe heat
exchangers or screw-in immersion heaters, the tank must be completely filled with
drinking water. Otherwise, damages at the enamel are possible.
6
Connection3.1
Mixed installations3.2 According to technical rules, an appropriate electrical separation of the conductive
connection between the different materials has to be provided for mixed installations.
With the smooth-pipe heat exchangers flowed through by heating water, an electrical
separation in the flow and return line has to be made additionally in order to prevent
a short circuit via the mandatory grounding of the line.
Pressure shocks /
water hammers
3.3 When installing fast-closing shut-off and water-tapping valves (solenoid valves, ball
valves, single-lever mixers), it might come to short-term pressure shocks in drinking
water installations becoming noticable in the form of disturbing noises and eventually
leading to wear and break of pipes and storage tanks. When using such components,
appropriate water hammer dampers are to be provided. We assume no liability for
damages caused by pressure shocks and water hammers.
Commissioning3.4 Commissioning the storage tank is performed in the following steps:
• filling the storage tank
• opening the tapping points until the water streams out
• setting the safety valve
• heating up the storage tank after complete filling
IMPORTANT: All pre-assembled connections (e.g magnesium protective anodes and
service hatch) have to be checked for tightness before commissioning. After the first
heating up, all connections must be checked for correct seat or have to be retightened
if necessary. We assume no liability for damages caused by water.
IMPORTANT: For an optimal insulating effect, there must not be any condensing humidity
within the insulation. A damp insulation can be dried by lifting the top storage tank cover
temporarily during active operation.

Control, maintenance
and cleaning
4
When commissioning – as well as at least once a year – the correct function of the safety
valve has to be tested. If the safety valve is constantly dripping, this is probably caused by
contamination, the pressure in the water pipe exceeds the permitted value or the safety
valve is defect. If the pressure in the water pipe exceeds the permitted value, a pressure
reducer has to be installed.
IMPORTANT: During the heating, expansion water visibly leaks from the safety valve.
Do not close!
Safety valve 4.1
The storage tanks are enamelled on the drinking water side in accordance with DIN Part
and are supplied, depending on their size, including one or two pre-assembled magnesium
protective anodes. According to DIN , Part , magnesium protective anodes must be te-
sted yearly and replaced every two years.
Optionally, maintenance-free impressed-current anodes of different makes can be
retrofitted. It is of utmost importance that all magnesium protective anodes integrated
in the storage tank are removed to prevent a disruption or malfunction of the impressed-
current anode. The impressed-current anodes may only be connected by qualified personnel
and according to the installation instructions of the manufacturer. The impressed-current
anodes are subject to the warranty conditions of the manufacturer.
Corrosion protection 4.2
Flanged aperture 4.3
Enamelled domestic water storage tanks GB
Art.
Storage tank flange seal EPDM
for service hatch
If storage tanks are fitted with service hatches, the flange seal has to be checked in
regular intervals. A yearly interval is recommended.
After opening the flange, a new seal must be installed.
The nuts have to be tightened by hand first and then fastened diagonally with
a torque between and Nm.
8
The domestic water is drained after closing the shut-off valve in the cold water supply line
via the drain valve of the safety valve combination while simultaneously opening all hot
water valves of the connected functional fittings.
Draining4.4
Required cleaning intervals are different depending on the water quality and the
temperature of the storage tank. A yearly interval is recommended.
IMPORTANT: With a drinking water hardness of over ° dH, a yearly cleaning interval
is a prerequisite for preserving any warranty claims.
The cleaning is done through the flange aperture. The enamelled internal surface prevents
limestone formation as far as possible and allows for a quick cleaning of lime deposits by
means of a sharp water jet. Incrustations may only be crushed with a wooden stick before
the flushing. Sharp and/or metal objects may not be used for cleaning as there is the risk
of damaging the tank or the enamel.
IMPORTANT: After the cleaning, the connections have to be checked for tightness again
before and after the reheating and they have to be retightened if necessary. We assume
no liability for damages caused by water.
