damage
1.2 Intended use
There is a risk of injury or death to the user or
others, or of damage to the product and other
property in the event of improper use or use
for which it is not intended.
The domestic hot water cylinder is designed
to keep drinking water that is heated to a
maximum 85 °C ready for use in households
and businesses. The product is designed to
be integrated into a central heating installa-
tion. It is designed to be combined with heat
generators whose power lies within the limits
specified in the technical data. To control the
domestic hot water generation, weather com-
pensators and control systems from suitable
heat generators can be used. These are heat
generators that provide cylinder charging and
can be connected to a temperature sensor.
Intended use includes the following:
–observance of accompanying operating,
installation and servicing instructions for
the product and any other system compon-
ents
–installing and fitting the product in accord-
ance with the product and system approval
–compliance with all inspection and main-
tenance conditions listed in the instruc-
tions.
Intended use also covers installation in ac-
cordance with the IP class.
Any other use that is not specified in these
instructions, or use beyond that specified in
this document shall be considered improper
use. Any direct commercial or industrial use
is also deemed to be improper.

1 Casing top
2 Display element
3 Cleaning eye
The product is a domestic hot water cylinder. The domestic
hot water cylinder is equipped with external heat insulation.
The vessel for the domestic hot water cylinder is made of
enamelled steel. The pipe spirals that transfer the heat are
located inside the vessel. As additional corrosion protection,
the vessel has a protection anode.
A circulation pump can be used as an option to increase
the hot water comfort, particularly at more distant draw-off
points.

requirements of the applicable directives as stated on the
identification plate.
The declaration of conformity can be viewed at the manufac-
turer's site.
4 Setting the target cylinder
temperature
Danger!
Risk of death from Legionella.
Legionella multiply at temperatures below
60 °C.
▶Ensure that the operator is familiar with all
of the Anti-legionella measures in order
to comply with the applicable regulations
regarding legionella prevention.
1. Set the target cylinder temperature.
–Water temperature: ≥60 ℃
2. Check the water hardness.
Water temperature: > 3.57 mol/m³
▶Soften the water.
3. Check the conductivity.
Conductivity: > 1,250 µS/cm
▶Take measures to protect against corrosion.
4. Take protective measures against legionella.
5 Handing over to the operator
1. Teach the end user how to handle the installation. An-
swer any questions the operator may have. In particu-
lar, draw attention to the safety information which the
operator must follow.
2. Explain to the operator how the safety devices work and
where they are located.
3. Inform the end user that they must have the product
maintained in accordance with the specified intervals.
4. Provide the operator with all relevant instructions and
unit documentation for safe-keeping.
5. Inform the end user about the ways to limit the domestic
hot water outlet temperature so that scalding can be
prevented.
6. Inform the end user about the legionella protection
measures that have been taken.

6 Troubleshooting
6.1 Detecting and rectifying faults
▶If problems occur whilst operating the product, check
certain points with the aid of the table in the appendix.
Detecting and rectifying faults (→Page 7)
6.2 Procuring spare parts
The original components of the product were also certified
by the manufacturer as part of the declaration of conformity.
If you use other, non-certified or unauthorised parts during
maintenance or repair work, this may void the conformity of
the product and it will therefore no longer comply with the
applicable standards.
We strongly recommend that you use original spare parts
from the manufacturer as this guarantees fault-free and safe
operation of the product. To receive information about the
available original spare parts, contact the contact address
provided on the reverse of these instructions.
▶If you require spare parts for maintenance or repair
work, use only the spare parts that are permitted for the
product.
7 Decommissioning
1. Disconnect the power supply, if required.
2. Close all of the isolators fitted on-site.
3. Drain the cylinder (→installation instructions).
4. Disconnect the connection cables.
5. Remove the cylinder and correctly dispose of the indi-
vidual components (→installation instructions).
8 Recycling and disposal
Disposing of the packaging
