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

Mounting instruction:

This float switch must be mounted horizontally.
- unscrew the float,
- screw the float switch with its seal into the G1 tank socket or flange borehole,
- seal in place,
- 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,
- screw back in place the float.
