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 author-
ised contractors.
■Work on electrical equipment must only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for the protection of the envi-
ronment
■Codes of Practice of the relevant trade associations
■All relevant safety regulations as defined by DIN, EN,
DVGW, VDE and locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI, SWKI and SVGW
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.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of your
system.
Replace faulty components with genuine
Viessmann spare parts.
Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacements, use only original spare parts
supplied or approved by Viessmann.

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.

1. Fill the DHW cylinder from the DHW side.
Note
Once the DHW cylinder is pressurised, retighten
the flange cover with a torque of 40 Nm.
The cylinder cap does not need to be retightened.
2. Check the fittings on the heating water and DHW
sides for leaks and retighten if required.
3. Check sensor wells for leaks and retighten if
required.
4. Check the function of the safety valves according to
the manufacturer's instructions.
Inspection and maintenance
DIN 1988 requires a visual inspection and (if neces-
sary) cleaning no later than 2 years after the cylinder
has been commissioned, and thereafter according to
requirements.

1. Drain the DHW cylinder from the DHW side.
2. Remove top panel A, hood B, thermal insulation
mats C and thermometer sensor D.
3. Remove flange cover E and cylinder cap F with
stainless steel circular blank G and gaskets H.
4. To prevent cleaning agents and contaminants
entering the pipework, separate the DHW cylinder
from the pipework.
5. Remove loose deposits with a high pressure
cleaner.
!Please note
Pointed or sharp cleaning tools will damage
the cylinder interior.
Only use plastic tools to clean the inside.
6. Use a chemical cleaning agent to remove hard
deposits that cannot be removed with a high pres-
sure cleaner.
!Please note
Cleaning agents containing hydrochloric acid
attack the DHW cylinder material.
Never use such cleaning agents.
Danger
Cleaning agent residues can result in poi-
soning.
Always observe the information provided by
the cleaning agent manufacturer.
7. Fully drain all cleaning agent.
8. Flush the DHW cylinder thoroughly after cleaning.
