If there is already sample water in the in-line probe
housing
Slowly lower the sensor into the in-line probe housing.
Otherwise the diaphragm of the sensor is over‐
stretched and the sensor delivers incorrect values.
1.
Remove the securing bolt (1) using a 35 mm ring spanner
2.
Fit the sensor with electrolyte as described in the sensor
operating instructions
3.
Push the O-ring (4), then the assembly washer (5) onto the
sensor (3) from below
ð
The components must lie against the clamp disc (2)
4.
Then push the securing bolt (1) from above onto the sensor

5.
Carefully push the sensor (3) into the module (6) of the in-line
probe housing
6.
Tighten the securing bolt (1) using a 35 mm ring spanner

Electrical installation
If power sockets are provided on the metering system,
then the socket on the side of the metering pump
should always be used. The power socket is controlled
so that it switches the pump which is installed on the
same side as it.

Screw the orange-coloured SN6 plugs onto the sensors
2.
With level switch: Plug the plug of the level sensor cable into
the
[level] socket of the metering pump
