Mounting
When working on tanks for storage of flammable liquids, all local safety and accident
prevention regulations must be observed as a matter of principle.
When filling static tanks with water-polluting liquids, the tanks may only be filled up
to their permitted level (see the German Water Resources Act resp. corresponding
national rules and regulations).
Installation in protective tubes or dipstick pipes is not permitted.
(1)
The Overfill Prevention Sensor must always be installed in a vertical position in the
tank. Installation is via a screw-in unit. Provide the thread of the screw-in unit with a
suitable sealant and screw into the tank coupling. Release the locking screw and the
stuffing box (see Figure below). To obtain the correct position, the Overfill Prevention
Sensor can be moved upwards and fixed in position.

(2)
Determine the adjustment dimension "x" for the Overfill Prevention Sensor (see Sec-
tion 4.4). The adjustment dimension "x" is the distance between the hexagon nut seat
of the screw-in unit and the groove marking on the sensor's protective sleeve at the
lower end of the probe.
(3)
Set the height of the Overfill Prevention Sensor to the control dimension "y" (see Sec-
tion 4.2). The control dimension "y" is the distance between the hexagon nut seat of
the screw-in unit and the upper groove marking on the probe tube.
(4)
Then re-tighten the stuffing box and locking screw.
