Waste water tank
Fresh water tank
Install the cables to the tanks and power supply.
Connect the sensors to the panel and the power supply. The
plug connectors can only be inserted to the correct connection
when they are in the right position.
Ensure that all the catches lock into place.

Establish the height of the
tank (external dimensions).
Establish and mark the posi-
tion of the boreholes for the
sensors.

Drill 2 holes with a diameter
of 9.5 – 10 mm into the
waste water tank.
Smooth down the edges of
the boreholes.
Coat the screws with seal-
ing compound or an elastic
adhesive.
Assemble the measuring
sensors (1 wire of the 2-wire
line per measuring sensor).
Tighten the screws by hand.
Place each measuring sen-
sor into a borehole and
tighten with a screwdriver.
The edge of the rubber
seal is pressed against
the tank wall. The rubber
bulges inside thereby sealing
the borehole.

Establish the height of the
tank (external dimensions).
Drill the borehole with a
diameter of 38 ± 0.5 mm
at the highest point close
to the middle of the tank
and the cleaning opening.
If necessary, shorten the
measuring rods (see short-
ening table).
Insert the sensor into the
cleaning opening and
screw tight – observe the
correct position of the
sealing ring.
Tighten the nuts by hand.

The table applies for symmetrically shaped tanks.
The volume of non-symmetrical tanks needs to be
determined.
