SAFETY INSTRUCTIONS
General
• This storage tank can be used by children eight years old and older as well as by persons with re-
duced physical, sensory or mental capabilities or who lack experience and knowledge if they are
supervised or if they have been trained with regard to the safe use of the storage tank and under-
stand the resulting risks. Children may not play with the storage tank or its packaging. Cleaning and
user maintenance may not be performed by children without supervision.
• The storage tank may only be installed and operated as described in this manual or the associated
technical information. Any other use is not in accordance with instructions and is therefore imper-
missible.
• A defective storage tank may not continue to be operated.
• There is a risk of scalding from hot water or hot components (e.g. ttings, hot water outlet pipe,
etc.).
• When using an electric immersion heater, proper corrosion protection is to be ensured.
Installation and commissioning
• Installation and commissioning may only be performed by qualied specialised personnel who
therefore assume the responsibility for proper assembly in accordance with the applicable laws,
standards and guidelines.
• The storage tank is mounted to a sufcient load-bearing wall using a wall mount (note the total
weight of the lled storage tank) or is placed on a at horizontal surface (install supporting feet
depending on the type). Ensure that the subsurface at the installation location has a sufcient
load-bearing capacity.
• The storage tank may only be set up in dry, frost-protected spaces. The storage tank is to be com-
pletely emptied if there is a risk of freezing.
• The rated pressure specied on the nameplate may not be exceeded.
• When installing the storage tank, a possible water leak is to be considered and a corresponding
collection container (including drain) is to be installed in a drainage object.
• Following commissioning, the storage tank and all connections are to be checked for leak tight-
ness.
Electrical Connection
• Only qualied specialised personnel may connect the storage tank to xed lines while observing
the relevant professional standards and laws.
• A ground fault circuit interrupter with a trip current of I∆n ≤ 30mA must be installed upstream from
the electrical circuit.
• Before working on the storage tank, the latter is to be de-energised, checked for the absence of
voltage and secured against being switched on again.
• If a connection cable is damaged, immediately disconnect the power supply (circuit breaker) and
call a professional!
• Connection cables may not be extended or cut through in any way.
Maintenance
• Maintenance, cleaning and any necessary repair or service work may only be performed by special-
ised personnel who are qualied for this purpose.
• Never try to x errors and faults yourself.
• Necessary service and maintenance intervals are to be observed in accordance with these operat-
ing and assembly instructions.

FUNCTION
The domestic water stored in the enamelled internal boiler is heated up by the electrical heating element.
The user can preselect the desired temperature on the operating panel. The heating is independently
switched on during heating-up process by the control and switched off again after reaching the desired
stored water temperature.
If the water temperature drops, for instance due to water abstraction or natural cooling (the high-quality
CFC-free polyurethane foam insulation keeps it as low as possible), the device switches itself back on
again until the stored water temperature is reached.
HOT WATER REQUIREMENT
Hot water consumption in the household is dependent upon the number of people, the sanitary ttings in
the at or house, the insulation, the plumbing and the individual habits of the user.
The following table provides a few standard values for consumption.
The temperature of the cold water required for mixing for the stated hot water temperature was assumed
to be approx. 12 °C.
SAVING ENERGY
Our electrical storage system is a real energy saver due to its high quality, CFC-free polyurethane foam
insulation and its built-in control system.
Low storage water temperatures turn out to be particularly economical.
That is why the level of the temperature adjustment should only be set in accordance with the actual hot
water requirements. This helps save energy and reduces limescale build-up within the container.

STANDBY ENERGY CONSUMPTION
If a water heater is heated up and no water is released for a long time after the heating process, a cooling
of the stored water via the surface of the device, albeit gradual but continuous, will be the result.
The intensity and speed of his cooling off will vary according to the construction type of the device, the
size of the device, thickness and quality of the container insulation.
This behaviour is measured at a stored water temperature of 65°C over a period of 24 hours and the
amount of energy required to keep the water at a constant temperature throughout this period is meas-
ured in kWh.

OPERATING REQUIREMENTS
The storage tanks must be used exclusively in accordance with the conditions set out on the rating panel.
The maximum input pressure should correspond to the nominal pressure stated on the rating panel. In
addition to the legally recognised national guidelines and standards, the connection conditions of the local
electricity and water works as well as those set out in the operating and assembly instructions must be
complied with.
The room where the device is used must be frost-free. The installation of the device must be carried out
in a place where one might reasonably expect it to be, i.e. the device must be easily accessible in case of
servicing, repairs or in case it needs to be replaced. The hot water storage tank must only be connected
to rigid/xed plumbing. In the case of extremely hard water, we recommend the upstream installation of
a commercially available de-calcication device and a maximum operating temperature of about 60°C.
Appropriate drinking water quality is required for proper operation.
In order to prevent the ingress of foreign bodies, we recommend the upstream installation of a water lter.
Should a device, at the point of delivery, clearly display a malfunction, damage or other defect, this must
not tted, used in the system or commissioned. Subsequent complaints regarding devices with an ob-
vious defect which have been connected and installed are expressly excluded under the warranty and
guarantee.
INSTALLATION AND SAFETY INFORMATION
a) Important installation information! Do not bend the safety component sus-
pension hooks as they may break. Failure to take notice of this warning could
result in personal injury due to a falling device!
b) Every device is delivered with a wall rail for the insertion of the upper securing
hook, which is attached to the wall with two screws and which supports the weight
of the device. Two additional screw ttings (as per the dimensions sketch with the
device dimensions) must be provided for afxing the lower tab of the device to the
wall; this only serves to secure the device against the wall and to prevent lateral
movement. The lower wall bracket has no supporting function and may therefore
not be subject to any excessive stress. Lifting and/or supporting the electrical storage heater on the
lower wall bracket is prohibited, as this strain can lead to the wall bracket tearing off! Water heaters of
a suspended construction type must not be installed horizontally.
c) The securing hooks and therefore the suspension dimension A can be repositioned by moving the stor-
age tank rear wall screws into other holes of the hook in 50 mm spacings. The xing hook must always
be attached to the rear wall of the storage tank with at least two screws!
Warning: Only xing hooks provided by the manufacturer may be used! If the assembly height is
changed, this is to be tightened to the mounting screws with a torque of 40 - 50 Nm.
d) During installation, due attention must be paid to device dimension sketches and any information signs
that may have been supplied together with the device.
e) Warning: The weight of the water heater including the weight of the water content (the nominal capac-
ity) must be taken into consideration for the selection of an installation point and/or the preparation a
device mounting surface sufcient to meet the technical loading and installation strength requirements.
Special suspension, see narrow wall and/or ceiling mounting.

14
Id. no.: 242440-7
f) If a water heater is tted with covers (cladding) in narrow small spaces or in suspended ceilings and the
like, it is crucial to ensure that the connection side of the device (water connections, electrical connec-
tion room and/or boiler room) remains freely accessible and that there is no heat accumulation. There
must be a free space of 500mm for the dismantling of the heating ange. A space of at least 50mm
must be left above the device so that it can be hooked into the wall rails.
g) In terms of the choice and/or sequence of installation material used on the system side (be careful in
the case of mixed installation) due consideration must be given to potential electro-chemical processes
(e.g., copper-steel contact corrosion) in accordance with good engineering practice. We recommend
the installation of insulating screw xings.
h) If there is particularly aggressive water, which demands a special solution on the installation side, the
potential need for special constructed versions of the storage tank should be investigated (please di-
rect any related questions to our agents or directly to our company).
i) The device is equipped with a safety temperature limiting device, which prevents any further heating of
the devices beyond a water temperature of 110°C. (EN 60335 -2-21; ÖVE-EW41 , Part 2 (500) /1971).
The connection components (connection pipes, circulation, safety valve combinations etc.) should there-
fore be chosen in such a way that the connection components could withstand temperatures of 110 °C in
case of any potential malfunction of the temperature regulator and that possible consequential damages
are avoided.
j) The assembly and installation may only be carried out by authorised tradesmen.

Comments
The values stated are guide values, measured in accordance with the specications of the ErP (energy-re-
lated products) Directive.
The actual values depend on the individual circumstances (number of people in the household, sanitary
ttings in the at or house, plumbing insulation, etc.) and can therefore deviate from the values stated.
DOMESTIC HOT WATER SIDE CONNECTION (PRESSURE RESISTANT)
In cases in which unsuitable or non-functional storage tank connection ttings are used as well as in cas-
es in which the stated operating pressure is exceeded, we shall refuse to guarantee the water heater in
any way whatsoever. All tanks and boilers which have the description “max. operating pressure 6 bar” or
“max. operating pressure 10 bar” on the rating place are pressure resistant tanks. The connection and/or
connection components (e.g. safety valve, pressure reducer) must be designed and dimensioned accord-
ing to national standards and regulations (e.g. DIN 1988-20; ÖNORM EN 806-2).
Warning: The pipe water pressure must be suitable for the safety valve. If necessary, install a pres-
sure reducer. The water connection must only take place via a certied membrane safety valve or a
membrane safety valve combination - connection tting for pressure resistant storage tanks.
A safety valve combination consists of shut-off, back-ow, drainage and safety valves with expandable
water outlet and is installed between the storage tank's cold water inlet pipe (blue) and cold water inlet in
an appropriate sequence.

The following must be observed:
In order to ensure the faultless functioning of the connection ttings these may only be installed in frost-pro-
tected spaces. The outlet of the safety valve must be open and observable and/or the outlet pipe from
the drip tray (water overow funnel) must not terminate outside so that neither frost nor blockages due to
dirt and the like can result in a malfunction. Care must be taken to ensure that the drip container does not
become blocked.
Furthermore, care must be taken to ensure that the outlet pipe of the safety valve is installed at a steady
incline.
The outlets of the safety valves (domestic water as well as heating circuits) must lead to a corresponding
drainage object in order to prevent any damage from the outlet of operating liquid.
No shut-off valve or any other restriction may be installed between the safety valve and the storage tank
cold water inlet.
The safety valve must be congured for a trigger pressure that is lower than the nominal pressure (6 bar)
of the storage tank. Before the nal connection of the storage tank the cold water inow pipe must be
ushed through.
Once the water has been connected and the storage tank has been lled without air bubbles, the function
of the connection ttings must be checked.
a) In order to avoid a blockage of the safety valve's venting mechanism as a result of lime-scale deposit-
ing, the safety valve's venting mechanism should be operated from time to time during the operation of
the system. It should be observed whether or not the valve re-closes after releasing the venting mech-
anism and whether or not the queued water is drained off completely via the funnel or outlet pipe.
b) In the event safety valves are installed before water heaters, a check should be made as to whether the
safety valve reacts when the water heater is heated up. This can be veried by way of water egress out
of the outlet pipe.
Implementation: operator, installation company
Interval: every 6 months
Maintenance and repair:
If no water escapes when the water heater is heated up or if the safety valve is permanently leaky, then an
attempt should be made to unblock the valve or remove any foreign bodies (e.g., limescale particles) on
the seal component by operating the venting mechanism several times.
If this fails then an overhaul by an installation company should be arranged. In case of damage to the valve
seat or seal then the safety valve will have to be completely replaced.
Implementation: Installation company
Interval: annually
To check the back-ow valve the shut-off valve is closed and no water should escape via the open test
valve.
The operation of the storage tank takes place via the hot water valve of the control device (mixing unit).
Therefore the storage tank is permanently under pressure. In order to protect the inner boiler from over-
pressure during heating-up, the excess water that arises is drained off via the safety valve. To avoid over-
pressure damage to the water heater it is crucial to replace calcied safety valves. In the event of a drop
in pipeline pressure, the back-ow valve prevents the back-ow of the hot water into the cold water pipe
system thereby protecting the boiler from being heated up in the absence of water. The storage tank can
be separated from the cold water supply grid through the shut-off valve on the water side and therefore
also in terms of pressure and can be drained off via the drainage valve if necessary.

Id. no.: 242440-7
In order to allow repairs to be carried out easily and to allow the device to be removed or replaced, it is
necessary to establish the connection to the tank by means of a detachable connection (union). Storage
tank leaks as a result of an improper connection and resulting damage and consequential damage are
excluded from the warranty and product liability.
ELECTRICAL CONNECTION
General information
a) The electrical connection must always be implemented in accordance with the circuit diagram pasted
in to the connection space of the storage tank!
b) Ensure the correct connection voltage!
c) An all-pole isolation switch with a contact opening width of 3mm is to be provided in the electrical
supply line. Automatic circuit breakers are also permissible as isolators.
d) The connection cable must be inserted into the connection space of the storage tank and be prevented
from being pulled out and twisted by a strain relief mechanism.
e) For installation and intrusive interventions into the device, the hot water storage tank must rst be
isolated completely (all poles) and on every side from the power supply in compliance with EN 50110
(ÖVE, TAEV). Before carrying out any further work, the system must be secured against the accidental
reconnection of the power supply (remove the fuses, trigger the mains circuit breaker).

INITIAL COMMISSIONING
Before switching on the electrical power the storage tank must be lled with water.
During the heating up process the expansion water generated in the inner boiler must drip out of the safety
valve in the case of a pressure resistant connection and out of the mixer unit in the case of a non-pressure
connection.
Warning: the initial heating up process must be carried out and monitored by a licensed profession-
al. The hot water drainage pipe as well as parts of the safety ttings can get hot.
After heating up the congured temperature and the actual temperature of the extracted water should be

If a water heater is put out of action or remains unused for a lengthy period then it must be drained and
completely isolated (at all poles) from the power supply. Switch off the supply line switches or automatic
circuit breakers.
In rooms permanently subject to frost damage, the water heater must be drained before the start of the
cold weather season if the device will be out of action for several days and is not being operated in frost
protection mode.
The draining of the domestic water is carried out once the shut-off valve has been closed in the cold water
feed via the drainage valve of the safety valve combination whilst all hot water valves of the connected op-
erating mechanisms are simultaneously open. It is also possible to drain the system via the safety valve in
the excess water funnel (drip tray). In order to do so the safety valve knob is turned to the "Test" position.
Careful: hot water can escape when draining.
In addition, where there is a risk of frost, it is important to note that not only the water in the water heater
and warm water pipes can freeze, but that the water in all the cold water pipework leading to the operat-
ing mechanisms and to the device itself can freeze too. It is therefore useful to drain off all water-carrying
ttings and plumbing right back to the frost protected part of the household water system (household
water connection).
If the storage system is brought back into service then it is crucial to ensure that it is lled with water and
that bubble-free water emerges at the hot water valves.

INSPECTION, MAINTENANCE, SERVICING
a) During heating-up excess water must be seen to drip out of the safety valve outlet (in the case of
non-pressure connections the excess water will drip out of the mixer unit valve). When fully heated up
(approx. 75 °C), the excess water volume is approx. 3.5% of the storage tank volume.
The function of the safety valve should be checked regularly. When lifting or turning the safety valve
testing knob to the "Test" position the water must ow unhindered out of the body of the safety valve
and into the drainage funnel.
Warning: the cold water inlet plumbing and parts of the storage tank connection ttings can be-
come hot as a result.
If the water heater is not heated up or if no hot water is extracted, then no water should drip out of the
safety valve. If this is the case then either the water feed pressure is too high (install via 5.5 bar pressure
reduction valve) or the safety valve is defective. Please called the installation expert immediately!
b) In the case of extremely hard water, the boiler scale accumulating in the storage tank's inner boiler as
well as the freely deposited lime-scale must be removed by a professional after one or two years of
operation.
Cleaning is carried out by removing the ange opening of the heating ange and cleaning the storage
tank. When re-installing the heating ange it is crucial to use a new seal. The specially enamelled inner
container of the water heater must not come into contact with boiler scale solvent - do not use the
de-calcifying pump. Remove limescale with a wooden instrument and then take out with a vacuum
cleaner, or wipe it out with a cloth.
The device must then be thoroughly rinsed (in accordance with ÖNORM H5195) and the heating up
process is to be observed as per initial commissioning.
c) In order to make substantiated claims under the guarantee provided, the in-built protective anode re-
quires an inspection by an expert at maximum intervals of 2 years of operation. The protective current
resistor below the heating element xing screw must not be damaged or removed during servicing.
d) Do not use any scouring agents to clean the device and do not use any paint thinners (such as Nitro,
trichloride, etc.)
It is best to clean it using a damp cloth with a few drops of a liquid household cleaning agent. In hospi-
tals and other public buildings, it is essential to comply with the prevailing regulations for cleaning and
disinfection.
For service work, it is also appropriate to open the cleaning and service ange, in order to check the tank
for the possible ingress of foreign bodies and impurities and to remove them if necessary.
MALFUNCTIONS
If the storage tank water does not heat up please check whether the circuit breaker (automatic circuit
breaker) in the distribution cabinet or the safety fuse have been tripped and check the setting of the tem-
perature regulator.
In any other instances do not attempt to rectify the fault yourself. Either contact a licensed installer or our
Customer Service department for assistance (Austria-wide). Professionals often only need to make a few
quick adjustments to return the storage tank to full working order. Please provide the type designation
and serial number of your storage tank when reporting the issue, which you will nd on the rating plate.
