4. Operating conditions

Use fitted heater exclusively in the conditions specified on the rating plate (operating pressure,
heating time, supply voltage etc.). The electrical connection must be made according to
the wiring diagram on the inside of the protection cover.
Apart from the nationally acknowledged rules and regulations (ÖVE = Association of Austrian
Electrical Engineers, VDE = Association of German Electrical Engineers, ÖNORM = Austrian
standard and DIN = German standard, etc.), the connection conditions of the local power
station and waterworks as well as the Operator's Manual and Installation Instructions must
also be observed.
If the lime concentration of the water is very high, we recommend fitting a commercially
available decalcifier upstream of the water tank.
This fitted heater is particularly suitable for the installation in freestanding enamelled tanks
and units with twin envelope. However, due to its special design, the units can also be fitted
in third-party products with enamelled, plastic coated or hotdip galvanised boilers.
A combination with CrNi (NIRO) boilers is problematic and not recommended (necessary
measures: see item 5.4). For the installation in enamelled boilers, our fitted heaters, screw-in
heaters and fitted gilledpipe heat exchangers are designed with insulated heating elements
in connection with a protective current discharge resistor and therefore comply with the state
of the art – in particular concerning the protection against corrosion of enamelled boilers. All
built-in heating components are suitable for pressure- resisting operation and the heating of
drinking or heating water up to a max. operating pressure of 10 bar (150 psi).
Built-in heating systems are not suitable for use in aggressive media (alcohol, glycol,
oil, etc.)!
This device is not designed to be used by persons (including children) with physical, sensory
or mental disabilities or lacking experience and/or lacking knowledge, unless these are
supervised by a person who is responsible for their safety or have received instructions on
how to use this device from any such person. Children should be supervised in order to
ensure that they do not play with this device.

5. Assembly, installation and safety information

5.1 General installation and safety information

In operation, the heating element and the sensor protection tube must be surrounded on
all sides by sufficient water. The water flow resulting from thermal influences should not be
impeded. The fitted heater features a safety temperature limiter that switches off any further
heating of the unit when the water temperature reaches max. 110° C (EN 60335 -2-21;
ÖVE-EW41, Pt 2 (500) / 1971). Therefore, when selecting the connection components
(con-nection pipes, safety valve combinations, etc.), it is necessary to ensure that the
connection components will withstand temperatures of 110° C so that any consequential
damage in the event of a malfunction of the temperature controller is prevented.
The assembly and installation must be performed exclusively by authorised trade personnel.
