■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.

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.

Siting information
!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, install the DHW cyl-
inder in a room free from draughts and risk of
frost.
When not in use, the DHW cylinder must be
drained if there is a risk of frost.
■Provide adequate clearance from the wall so that the
Vitosolic 100 can be operated (if installed).
■Use the adjustable feet to level the DHW cylinder.
Note
Never extend the adjustable feet beyond a total
length of 35 mm.

Note
■2 people are required for the following work.
■Ensure that no fleece remnants enter the DHW cylin-
der through the cylinder connections.
1. At the back of the cylinder: Attach 6 clip fasteners
to the edges of the right and left sections of the
thermal insulation jacket. Place the thermal insula-
tion jacket around the cylinder body.
Note
Leave the clip fasteners in the first notch.
2. At the front of the cylinder: Attach 5 clip fasteners
to the edges of the right and left sections of the
thermal insulation jacket. 3 clip fasteners at the
top, 2 at the bottom. Leave space for the Solar-Div-
icon.
3. Fit the thermal insulation jacket evenly around the
cylinder body by patting it.
4. Push the clip fasteners at the front of the cylinder
as close together as possible.
5. Push the clip fasteners at the back of the cylinder
as close together as possible.
