Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on electrical equipment may only be carried
out by a qualified electrician.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for environmental protection
■Codes of practice of the relevant trade associations
■Relevant country-specific safety regulations
Working on the system
■Isolate the system from the power supply (e.g. by
removing the separate fuse or by means of a mains
isolator) and check that it is no longer live.
■Safeguard the system against reconnection.
■Wear protective clothing.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing any work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Danger
Hot surfaces can cause burns.
■Before maintenance and service work, switch
OFF the appliance and let it cool down.
■Never touch the hot surfaces of uninsulated
pipes and fittings.
Danger
Floors which are wet, damp or covered in fluids
containing glycol present a risk of injury through
slipping and falling.
■When carrying out installation and mainte-
nance work, ensure that the floor is kept clean
and dry.
■Wear non-slip shoes.
Danger
Breathing in or swallowing broken-off fragments
of insulating material may result in death by
asphyxiation.
■Do not allow children to play in the installation
room.
■Clean the installation room after installation
and maintenance work.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of the
system.
Replace faulty components only with genuine
Viessmann spare parts.

Intended use
The appliance is only intended to be installed and
operated in sealed unvented systems that comply with
EN 12828 / DIN 1988, or solar thermal systems that
comply with EN 12977, with due attention paid to the
associated installation, service and operating instruc-
tions. DHW cylinders are only designed to store and
heat water of potable water quality. Heating water buf-
fer cylinders are only designed to hold fill water of pot-
able water quality. Only operate solar collectors with
the heat transfer medium approved by the manufac-
turer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than heating the building or DHW shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer for the individual case.

Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and results in an exclusion of liability.
Incorrect usage also occurs if the components in the
system are modified from their intended use (e.g.
through direct DHW heating in the collector).
Adhere to statutory regulations, especially concerning
the hygiene of potable water.

5. Only for heating water flow temperatures in excess
of 110 °C:
Install a type-tested high limit safety cut-out, if one
has not yet been installed in the system (see
pages 16 and 19). For this, use a temperature
limiter and a high limit safety cut-out.
Connections on the DHW side
■For the DHW connection, observe DIN 1988 and
DIN 4753 (c: SVGW regulations)
■Connect all pipework with detachable fittings.
■Seal any connections that are not required with red
brass caps.
■Equip the DHW circulation pipe with a DHW circula-
tion pump and a check valve.
■Connection of the DHW circulation pump:
–Connection to the boiler control unit, provided this
is equipped with a DHW circulation pump connec-
tion.
–Connection with a time switch, if there is no DHW
circulation pump connection on the boiler control
unit.

Safety valve
The system must be equipped with a type-tested dia-
phragm safety valve as protection against overpres-
sure.
Permissible operating pressure: 10 bar (1 MPa).
The safety valve must have the following connection
diameter:
R ¾ (DN 20), max. heat input 150 kW.
If the heat input of the DHW cylinder exceeds 150 kW,
select an appropriately rated safety valve for the heat
input (see E-DIN 1988-200).
Install the safety valve in the cold water line. Ensure
the safety valve cannot be shut off from the DHW cyl-
inder. There must be no constrictions in the pipework
between the safety valve and the DHW cylinder.
Never seal off the safety valve discharge pipe. Ensure
that any expelled water is safely and visibly drained
into a drainage system. Position a sign close to the
safety valve discharge pipe, or ideally on the safety
valve itself, with the following inscription: "For safety
reasons, water may be discharged from the discharge
pipe during heating. Never seal."
Install the safety valve above the top edge of the DHW
cylinder.

Electrical connections
Earth the appliance with the earth conductor at the
"PE" terminal. This cable must have at least the same
cross-section as the power cable. Never loop earth
cables, i.e. never route them from one appliance to
another.
