6 Mounting and commissioning

Do not install the control unit and the probe in hazardous areas
(EX areas).

ÖWWG 3 may only be installed, commissioned and maintained
by specialised companies according to §19 I of the German
Water Protection Act (Wasserhaushaltsgesetz WHG) or
according to the pertinent legislation in the country of installation
unless such activities are exempted from this obligation
according to the respective legislation or directives.
6.1 Mounting the probe

Select the mounting position in such a way that the PTC
thermistor is submerged even in the case of small amounts of
liquid so that it triggers the alarm as early as possible.

Mount the PTC thermistor probe at the lowest point of the area
to be monitored (lying or suspended).

The probe can be fastened by means of the clamp included with
the device. If the probe is mounted in a lying position, this clamp
also protects it from being stepped upon.

If the probe is suspended without support, push the enclosed
brass weight over the cable all the way to the probe head so
that the probe head with the PTC thermistor always hangs down
vertically.

Mount the control unit to an even, rigid and dry wall at eye level.


The control unit must be mounted in such a way that it cannot
