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.

Dispose of component correctly.
Dispose of component at a suitable collec-

domestic waste.
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.

To prevent damage to the thermal insulation and the
Solar-Divicon, both can be removed prior to transpor-
tation to the installation site.
Note
Ensure that no fleece remnants enter the DHW cylin-
der through the cylinder connections.

!Please note
The thermal insulation must not be able to come
into contact with naked flames.
Exercise caution when welding and soldering.
!Please note
To prevent material losses, site the DHW cylin-
der in a room free from the risk of frost and
draughts.
When not in use, the DHW cylinder must be
drained if there is a risk of frost.
■Provide adequate clearance from the wall for operat-
ing the Vitosolic 100 (if installed).
Note
To facilitate access to the connections on the solar
side, the Vitosolic 100 can be moved to the right or
left.
■Use the adjustable feet to level the DHW cylinder.
Note
Never extend the adjustable feet beyond a total
length of 35 mm.

Immersion heater EHE installation instructions
Maintain the minimum clearance.
!Please note
The unheated length of any threaded immersion
heater installed on site must be at least 100 mm.
The threaded immersion heater must be suitable
for installation in enamelled DHW cylinders.
Installing the immersion heater EHE (if available)
Connect the power supply only after the solar control
unit has been connected (see page 15).
Immersion heater EHE installation instructions
!Please note
To prevent equipment damage, cables must not
come into contact with hot parts.
Ensure adequate thermal insulation between
cables and hot pipework.
