Delivery, Transport and Storage

Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones you
ordered.
Keep the original packaging. Always store and transport the device in the original
packaging.
Always store the device in a clean and dry environment. The permitted storage
temperature (see data sheet) must be considered.

Installation and Commissioning

Installation of the Sensor
The sensor and warning device must be free of voltage during installation and
maintenance. The warning device must only be connected to the supply voltage
after complete mounting and connection of the sensors.
The sensor has IP68 protection and is weather- and oil/fat-resistant. It can
therefore be installed in grease interceptors.
When installing the device in oil/petrol separators, observe the permissible
ambient temperature in the range from -20 °C ... 60 °C (253 K ... 333 K).
Sensor Cable
Sensor cables must not be installed in cable or conductor bundles together with
other current circuits. Avoid installing sensor cables parallel to other cables that
may transmit interfering signals, which impair the sensor signal and thus the alarm
function. The sensor itself must not be grounded.
If you extend the sensor cable, observe the applicable specifications with regard
to color, quality and durability. Use unshielded cables.

Maintenance

For operation of grease interceptors, there may be standards, directives or laws
that define regular system or sensor tests. Check the operation of the sensor at
least twice a year and more frequently in the event of unfavorable environmental
conditions.
When the grease interceptor is being emptied (disposal), the sensor must always
be washed and dried. The sensor must not be cleaned with caustic fluids. A badly
contaminated sensor can trip a wrong alarm or, in certain circumstances, fail to
trip an alarm.
