TANK WITH TUBE REGISTER (PZR/PZRR 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
temperature 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.
A shutoff device should be installed in the flow in the case that a buffer tank with a tube register is instal-
led, so that backheating into the heating circuit is prevented in the case of switched off central heating
and heat pumping or electric operation.
However, under no circumstances must the flow and the return be shut off, as otherwise the water con-
tained 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 capa-
city) 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
regulations.
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 suffi-
cient 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 pos-
sible 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 person-
nel.
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 liability.
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
efficiency.
