Note
Ensure sufficient sizing of
the expansion vessel in the heating
circuit. The buffer volume and the
temperature difference that occurs
in the solar energy system must
included in the calculation!
6. Retension both hook closure strips hook by hook, start-
ing from the top or bottom, until they engage on the last
hook. The mounting aids (short cover strips) can be used
to fix them in place.
7. Put on the tank cover plate.
8. Clamp the cover strips over the hook closures.
9. If necessary, attach collars/caps.
10. Finally, glue the two accompanying base strips to the
lower end of the insulation.
Note: Do not mount the insulation at a room temperature
below 10 °C or press it with hard objects, since white cracks
could arise on the polystyrene surface.
Commissioning
Initial filling and placing into operation must be performed
by an authorised qualified technician. The function and
seal of the entire system, including the parts mounted in
the factory, must be checked. The operational reliability of
the safety valve and tank vent must be checked at regular
intervals. Yearly maintenance by a qualified technician is
recommended. Do not operate the tank above 95 °C. The
operating overpressures stated on the type plate must not
be exceeded.
VDI 2035
VDI Directive 2035 provides clear guidelines for the qual-
ity of the make-up water in the heatingsystem in terms of
maximum water hardness and pH-value.
Suitable measures must be employed to ensure that the
water is treated appropriate to its quality.
Electrical heating element
Electrical heating elements may only be connected
by certified electrical installers in accordance with
the corresponding switching diagram. The regulations
of the power company in effect must be observed.
The electrical heater (if available) must be descaled annu-
ally and at shorter intervals depending on the hardness of
the water. A function control must be
connected.
The electric threaded heating elements are only permitted
to be used as backup heating.
Warranty conditions
The manufacturer guarantees the storage tank
rust-proofness for 5 years from the invoice date.
All accessories are guaranteed for 2 years from the invoice
date.
