Safety instructions
Read these safety instructions before reading the following chapters.
3.1
Installation only by qualified personnel
Installation and repair of the impressed-current anode system CORREX
2.3-900 may only be performed by qualified personnel. Before installing
CORREX
MP 2.3-900 make sure:
®
1. the impressed-current anode system is operated in a closed and dry room,
2. the mains voltage corresponds to the voltage indicated on the rating plate,
3. the mains voltage is permanently available.
3.2
Safety instructions concerning the operation
To ensure proper functioning of the CORREX
following safety instructions must be observed:
1. The hot-water storage tank is not suitable for remaining in operation over
more than 2 months without tapping water from it. There is otherwise the
risk of gas formation which often manifests itself by a gurgling noise in the
tank and in the pipe system.
2. The plug-in potentiostat must not be disconnected from the mains supply
while the hot-water storage tank is full, or else the corrosion protection is
no longer ensured.
3. The connecting cable between plug-in potentiostat and tank must not be
detached when the tank is full, or else the corrosion protection is no longer
ensured.
4. The CORREX
prolonged downtimes (e.g. holidays), or else the corrosion protection is no
longer ensured.
3.3
Safety warnings concerning electrical tubular heating elements
Safety warnings for the operation of impressed-current anode systems in
enamelled hot-water storage tanks with electrical tubular heating element:
In hot-water storage tanks equipped with an electrical tubular heating element
mounted in an insulated hole, there is a risk of voltage transfer via the water
to metal parts of the tank not protected against accidental contact when the
electrical tubular heating element is defective. If these parts are touched, there
may be the risk of a fatal electric shock. For this reason it must be ensured
by regular maintenance of the electrical tubular heating element by a qualified
expert, for instance, a plumber or an electrical fitter, that the electrical tubular
heating element is in a safe operational state and that it is functioning properly.
