CAUTION!
Have the magnesium anode checked and if
necessary renewed by the customer service
for the rst time after 2 years and then at
appropriate intervals.
Renew anode if protective current lower than
0.3 mA. After replacing the anode, re-install
earthing cable between anode and storage tank
jacket.
NOTE
Descale electric heating elements (if installed)
annually, or at shorter intervals depending on
the hardness of the water. Carry out a functional
check at the same time.
Disposal
When withdrawing the old unit from service, comply
with the relevant local laws, guidelines, directives
andstandards concerning recovery, recycling and disposal.

Installation
Observe the following when performing all work:
NOTE
Always comply with the applicable local accident
prevention regulations, statutory regulations,
ordinances, guidelines and directives.
CAUTION!
The tank must be installed in a frostproof room,
to prevent frost damage to the storage tank,
pipe system and connections.
NOTE
Install the storage tank as close as possible to
the heat generator, to keep the heat losses as
low as possible. Ensure the shortest possible
pipe lengths to the load.
CAUTION!
The oor or ground at the place of installation
must be dry, rm and able to safely support the
weight of the tank.
For the weight of the tank, please refer to the
dimensioned drawing for the respective model.
ACCESSORIES
CAUTION.
Use only original accessories from the
manufacturer of the unit.

TRANSPORT TO INSTALLATION LOCATION
To avoid damage during transport, transport the
storage tank (secured on the wooden pallet) to its nal
installation location using a lifting truck.
WARNING!
The unit can tip over when being removed
from the wooden pallet and during
transport with a hand truck or lift truck.
This can result in personal injuries and
damage.
– Take suitable precautions to prevent
the tipping hazard.
NOTE
The storage tank is delivered fully insulated.
Dispose of the transport and packaging materials
properly and under ecological aspects.
INSTALLATION
When installing the tank, ensure sufcient clearance
from walls and other objects to enable the connection
pipes to be tted.
Installation
NOTE.
Always comply with the applicable local accident
prevention regulations, statutory regulations,
ordinances, guidelines and directives.
CAUTION
With our domestic-hot-water tanks, the follow-
ing plastic protective components can be deplo-
yed on and in the connections:
• Plastic plugs for internal threads (Protect the
threads and must be removed during installation.
For connections which are not required, they
must be replaced with pressure-resistant plugs):
Plastic plug
connecting piece
• Plastic caps for external threads (Protect the
threads and must be removed during installation.
For connections which are not required, they
must be replaced with pressure-resistant caps):

hammer in the cold water network and to
avoid unnecessary water loss, we recommend
installation of a suitable expansion vessel with
ow ttings.

83018600gUK – translation of the operating manual
CAUTION!
Do not exceed the operating pressures
specied on the rating plate. If necessary,
install a pressure reducer.
NOTE
Close off any connections not required with
appropriate plugs.
For position of the connections, please refer to
the dimensioned drawing for the respective model.
CAUTION!
Always integrate the tank in the system
according to the connection instructions.
Connection instructions from page 20.
Use the safety valve according to the respective current
standards, guidelines and directives and according to the
maximum allowae operating pressures of the storage
tank and components.
The safety discharge of the safety valve must be dischar-
ged into the drain via a funnel-shaped odour trap accor-
ding to the respective current standards, guidelines and
directives!
The discharge pipe connected to the safety valve must
be installed with continuous downward gradient in a
frost-free environment.
Water can drip from the safety valve
NOTE
The function of the pressure relief device must
be checked at regular intervals.
INSTALLATION OF THE SENSOR FOR THE HEATING AND
HEAT PUMP REGULATOR
Depending on the unit model, you must install the sensor
included in the scope of supply for the heating and
heat pump controller on site in of the sensor pockets
provided for this purpose. (In some models this sensor is
installed in the factory).
For item, see dimensioned drawing for
respective model.
Sensor connection:
see heat pump operating manual.
Domestic hot water temperature setting: s e e
controller operating manual
NOTE
In case of installation of the solar circuit with si-
multaneously installed electric heating element the
maximum storage tank temperature must be set
so that the safety temperature limiter (overheat
cut-off device) does not trip. To this end, follow
the separate operating instructions of the heating
element and solar controller.
Commissioning
Check whether the water supply is open and the
tank is full…
Check the safety valve is working properly (and if
applicable the pressure reducer)
Test the safety valve (and if applicable the pressure
reducer) for full functionality.
Storage tanks enamelled to DIN 4753 are suitable for
normal drinking water
Insulation of the connections
and the storage tank
NOTE
Insulate in accordance with applicable local
standards and guidelines/directives.
Check all hydraulic connections for leaks. Perform
leak test…
Insulate all connections and pipes.
NOTE
The function of the pressure relief device must
be checked at regular intervals.
Draining
The storage tank is drained via the drain valve (see page
18 - 19). Shut-off valves must remain closed during drain-
ing. The connection at the hot water outlet should be
open to the atmosphere.

NOTE.
The positions of the individual connections
illustrated here may differ from the positions
of the connections on your tank.
Therefore, for the actual positions of the
connections, please refer to the dimensioned
diagram for the respective tank type or
always note and follow the allocation of the
connections indicated by the stickers on the
tank.
