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.

Mixed installations
3.2
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.
Commissioning
3.4
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.
