1 Use
The domestic hot water tank serves for heating
and storing process water. Above all, solar systems and supplementary heating systems, like
gas, oil heaters or solid boilers, are the heat generators that come into consideration.
Any other use, or use over and above that described, will be considered not in conformity with
intended purpose. The manufacturer rejects all
liability for damage from usage not in conformity
with intended purpose and the owner/operator
alone bears the risk.
2 Safety Instructions and Explanation of Symbols
2.1 Safety instructions

7 Comissioning
Damage to property
Start up the machine only after it has
been completely fi lled
► Check the union nuts for fi rmness.
► Rinsing the machine.
► Filling and venting the machine till the system
is completely de-aerated.
► Before commissioning, check whether the
water supply has been opened and the tank
fi lled.
► The compact hot water storage tank may not
be operated above 95°C. The ideal operating
temperature is 50 - 60°C. With these operating temperatures, you can save energy and
avoid the heat-dependent calcifi cation.
► Electrical heating elements may only be in-
stalled by approved electrical technicians.
Care must be taken that the electrical heating element is connected in keeping with the
circuit diagram and in accordance with the
country-specifi c regulations. The specifi cations
of the EVU and VDE must also be mandatorily
observed.
► The electrical heating element should be
maintained annually and de-calcifi ed if re-
quired.
Flow noises
indicate air trapped in the machine.
After commissioning, the function and the air tightness of the entire machine should be checked.
6.1 Installation of the tank
► Electrical heating elements may only be in-
stalled by approved electrical technicians.
► A dry, frost-free room that provides suffi cient
space for maintenance work is requried as the
installation site.
► The compact hot water storage tank must be
installed so that it is protected from splashing
water and may only be run at room temperatures below 40 ° C.
► When positioning the tank, it is necessary to
ensure that the underlying ground is of suffi ci-
ent strength. .
► The tank should be positioned min. 10 cm
away from the wall
► The connections should be made according
to EN 806-1 and DIN 4753/1. To equalise
pressure variations or water hammers in the
cold water network and to avoid unnecessary
wastage of water, we recommend the installation of a suitable expansion vessel with fl ow
fi ttings.

9Warranty
We reserve the right to make changes owing to technical improvements..
• The cleaning of the tank and the inspection of
the plant should be carried out annually.
• The functional safety of the safety valve should
be checked at regular intervals, with an annual maintenance by technical personnel being
recommended. .
• The magnesium anode should fi rst be che-
cked the fi rst time after 2 years, according to
DIN 4753, and then every year, and replaced if
required.
7.1 Maintenance
The manufacturer has a warranty on the supplied
product and its components of 5 years from the
date of delivery.
Unauthorised modifi cations or changes are not
permitted for safety reasons and will inevitably
lead to the voiding of the warranty for the machine.
