Danger
This symbol warns against the risk
of injury.
!Please note
This symbol warns against the risk
of material losses and environmen-
tal pollution.
Note
Details identified by the word "Note"
contain additional information.
Target group
These instructions are exclusively inten-
ded for qualified contractors.
■Work on electrical equipment may only
be carried out by a qualified electrician.
■The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
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 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.

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
Auxiliary components, spare parts
and wearing parts that have not
been tested together with the sys-
tem can compromise its function.
Installing non-authorised compo-
nents and making non-approved
modifications or conversions can
compromise safety and may invalid-
ate our warranty.
For installation and replacements,
use only Viessmann original parts
or parts approved by Viessmann.

The appliance is intended to be installed and operated
only in sealed unvented systems that comply with
EN 12828/DIN 1988 or in solar thermal systems that
comply with EN 12977, with due attention paid to the
associated installation, service and operating instruc-
tions. Heating water buffer cylinders are exclusively
designed to hold fill water of potable quality. Operate
solar collectors only with heat transfer medium
approved by the manufacturer.
Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial use for purposes other than
room heating shall be deemed inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each 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 function.
Product information
Vitocell 140-E, type SEIC and Vitocell 160-E,
type SESB are steel heating water buffer cylinders for
heating water storage in conjunction with solar thermal
systems in systems that comply with EN 12828 and
DIN 4753.
The heating water buffer cylinders can be connected to
the following heat sources:
■Heat pumps
■Solar systems
■Solid fuel boiler
■Heat recovery
If a solar system is connected via the installed indirect
coil, the Solar-Divicon can be fitted directly to the heat-
ing water buffer cylinder as a pumping station for the
collector circuit.
The Vitocell 160-E, type SESB is fitted with a stratifi-
cation system for solar heating.
For DHW heating, the Vitotrans 353 freshwater module
can be fitted directly to the heating water buffer cylin-
der. DHW is heated according to the instantaneous
water heating principle.

Danger
Intense heat from a naked flame will melt the
thermal insulation. The resulting vapours may
be harmful to health.
Prevent the thermal insulation from coming into
contact with naked flames, e.g. when welding
and brazing.
!Please note
To prevent material losses, install the heating
water buffer cylinder in a room free from the risk
of frost and draughts.
When not in use, the heating water buffer cylin-
der must be drained if there is a risk of frost.
■Provide adequate clearance from the wall to allow for
operation of the temperature controller (if installed).
■Placing the heating water buffer cylinder on a plinth
will make the room easier to clean.
■Use the adjustable feet to level the heating water
buffer cylinder.

Danger
Intense heat from a naked flame will melt the
thermal insulation. The resulting vapours may
be harmful to health.
Prevent the thermal insulation from coming into
contact with naked flames, e.g. when welding
and brazing.
!Please note
If fleece remnants from the thermal insulation
get into the heating water buffer cylinder, they
will contaminate the heating water and may
result in operating faults.
■During installation, ensure that no fleece rem-
nants enter the heating water buffer cylinder
through the cylinder connections.
■Seal connections that are not required with
caps.
