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
■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.
■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.
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.

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.
Product information
Enamelled DHW cylinder with internal indirect coil for
DHW heating in conjunction with floorstanding boilers,
wall mounted boilers and/or immersion heaters (300 to
950 l capacity).
■For cylinder capacity and weight, see page 21.
■Suitable for systems conforming to DIN 1988,
EN 12828 and DIN 4753.

Siting information
!Please note
The thermal insulation must not come into con-
tact with naked flames.
Exercise caution when welding and brazing.
!Please note
To prevent material losses, site the DHW cylin-
der in a room free from the risk of frost and
draughts.
Alternatively, drain the DHW cylinder when not
in use and there is a risk of frost.
■Allow an adequate distance from the wall to enable
the temperature controller (if supplied) to be oper-
ated.
■750 and 950 l capacity:
For replacing the magnesium anodes, ensure a
clearance of at least 850 mm in front of the DHW
cylinder.
■Use the adjustable feet to level the DHW cylinder.
Note
Never extend the adjustable feet beyond a total
length of 35 mm.

Maintain the minimum clearance.
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

■300 l: Sensor retainer is supplied with the fascia.
■Secure the sensor on the outside of the sensor
retainer contact spring (not in the groove) so that it is
flush with the front of the spring.
■Never wrap insulating tape around the sensor.
■Insert the sensor retainer together with the sensor as
far as they will go into the sensor well.
■Insert the thermometer sensor as far as it will go into
the clamping bracket on the flange cover.
