TANK WITH TUBE REGISTER (PSR/PSRR TYPES)
Before bringing into use, the pipe registers must be flushed to remove any impurities from the heating circuit.
The heating water must be treated in accordance with the national regulations and standards (e.g. ÖNORM
H5195-1) during commissioning and comply with the regulations.
If the water heater is heated by its heat exchanger, then it must be ensured that in no case the hot water tempe-
rature exceeds 85 °C, as otherwise the safety temperature limiter of the electric heater can trigger and render it
inoperable.
The tube registers (heat exchangers) installed in the tank are suitable for the connection to a hot-water heating
at the pressure and temperature that is indicated on the rating plate of the buffer tank. Forced circulation by
means of a pump is required. If the heat exchanger is not connected, the connections must be sealed tightly to
prevent condensation water.
A shutoff device should be installed in the flow in the case that a buffer tank with a tube register is installed, so
that backheating into the heating circuit is prevented in the case of switched off central heating and heat pum-
ping or electric operation.
However, under no circumstances must the flow and the return be shut off, as otherwise the water contained in
the register cannot expand and a risk of damage to the heat exchanger exists.
The tube register must be rinsed through before being put into operation for the first time.
IMPORTANT MOUNTING INFORMATION
The dimensioned sketches and any possible labels included in the packaging must be observed for mounting
of the device.
CAUTION: the weight of the water heater including the weight of the water content (the nominal capacity) must
be taken into account for the technical load-bearing and strength-related arrangement of the mounting surface
of the device resp. for selection of the mounting location.
The distance to the boiler systems can be found in the manufacturer's documentation and in the relevant regu-
lations.
If a buffer tank with additions (cladding) is designed to be installed in small, tight spaces, it is important to ensure
that the connection block of the device (water connections, electrical connection space or heating installation
space) is freely accessible and that there is no build-up of heat. There must be sufficient free space to allow a
heating flange to be removed. To avoid corrosion, only prepared heating water should be used for filling (e.g.
ÖNORM H5195).
Failure to observe these rules constitutes improper use in the event of any damage and thereby excludes the
terms of the warranty.
Devices with electrically powered built-in heaters are equipped with a safety temperature limiter, which switches
off further heating of the device at a temperature of max. 110°C (EN 60335-2-21; ÖVE-EW41, part 2 (500)/1971).
Therefore, the selection of the connector components (connecting pipes, circulation, safety valve combination,
etc.) must be planned in such a way that the connector components resist temperatures of 110°C in the case of a
possible malfunction of the temperature controller, and that possible consequential damages are avoided.
Mounting and installation must be performed exclusively by authorised professionals.
The system operator must ensure that there is no risk caused by use of the system by untrained personnel.
In order to allow for a trouble-free repair, a removal or exchange of the device, it is necessary to establish the
connection of the tank by means of a detachable connection (Dutch). Tank leaks as a result of an improper
connection and resulting damage and consequential damage are excluded from the warranty and product lia-
bility.
Warning: The safety valve of the heating circuit must be provided with a suitable drain to remove any
heating water which may be produced.
We recommend that the connections and connection lines are properly insulated to improve the energy effi-
ciency.
