■Statutory regulations for the prevention
of accidents
■Statutory regulations for environmental
protection
■Codes of practice of the relevant trade
associations
■Relevant country-specific safety regu-
lations
Working on the system
■Isolate the system from the power sup-
ply (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 recon-
nection.
!Please note
Electronic assemblies can be dam-
aged by electrostatic discharge.
Prior to commencing any work,
touch earthed objects such as heat-
ing or water pipes to discharge
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 that are wet or damp with
water or glycol based liquids can
cause injury due to slipping and fall-
ing.
■Keep the floor clean and dry dur-
ing installation and maintenance
work.
■Wear non-slip shoes.
Danger
Broken-off fragments of insulation
material can cause death by suffo-
cation if inhaled or swallowed.
■Do not let children play in the
installation room.
■Keep the installation room clean
after installation and maintenance
work.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise the
safe operation of the system.
Replace faulty components only
with genuine Viessmann spare
parts.
Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have
not been tested together with the
system can compromise its func-
tion. Installing non-authorised com-
ponents and making non-approved

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.

!Please note
To prevent material losses, install the heating
water buffer cylinder in a room free from the risk
of frost and draughts.
Otherwise the heating water buffer cylinder will
need to be drained when not in use and there is
a risk of frost.
Note
Placing the heating water buffer cylinder on a plinth will
make the room easier to clean.

sors to the cylinder through the small apertures in
the thermal insulation mat.
2. Guide the upper thermometer sensor through the
lifting eye, insert it into the clamping bracket as far
as it will go and tighten the wing nut.
Secure the lower thermometer sensor (if available)
in the clamping bracket at the base of the cylinder.
3. Release the nuts.
4. Push the clamping system onto the threaded studs
and align.
5. Tighten the nuts.
6. Depending on where the sensor is being fitted:
Insert the thermometer sensors and cylinder
temperature sensors into clamping systems A
as far as they will go.
Note
Never wrap insulating tape around the sensors.
