This unit is not suitable for use in turbulent liquids (e.g. in stirrer tanks).

Mounting instruction:

This float switch must be mounted horizontally.
- seal and mount the float switch in the corresponding counter-flange,
- loose the two cheese head screws on the side – but do not remove –,
- set the connection head in such a way that the label “TOP” is at the top and the cable entry
  at the bottom,
- retighten the two cheese head screws.
