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 decalci-
fier 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 particu-
lar 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.
