This unit is not suitable for use in turbulent liquids (e.g. in stirrer tanks). Mounting instruction: This float switch must be mounted horizontally. - 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.
