4.2 Filling electrolyte
1.
Open the electrolyte bottle and screw on
the nozzle.
2.
Pour in the electrolyte, preferably free of
bubbles.
Place the electrolyte bottle on the dia‐
phragm cap and slowly press the elec‐
trolyte in a single stream from the elec‐
trolyte bottle, at the same time evenly
pulling back the electrolyte bottle.
ð
The diaphragm cap is completely
full if the diaphragm cap is filled to
the brim with electrolyte.

3.
Place the sensor vertically onto the filled
diaphragm cap.
4.
Do not use your fingers, or similar, to
close the vent hole, otherwise pressure
can build up when it is screwed shut and
the diaphragm can be damaged.
When screwing it shut, allow excess
electrolyte to escape through the vent
hole under the hose seal. The vent hole
must form the highest point to ensure
the reliable escape of air.
ð
If no electrolyte escapes when
screwing is shut, then the dia‐
phragm cap has not been suffi‐
ciently filled. Repeat this process
and fully fill the diaphragm cap.
5.
Turn the diaphragm cap manually as far
as the stop so that no gap can be seen
between the diaphragm cap and the
sensor.
6.
Rinse off any escaped electrolyte with
clean water.
7.
Close the electrolyte bottle.
8.
Rinse the electrolyte from the nozzle of
the electrolyte bottle under running
water.
ð
The sensor is now ready to be
installed in the bypass fitting.
