Installation conditions
Installation instructionsrange of application and minimum length between mounting and float:
- PUR version: ≥ 100 mm (4 inch), preferred for fuels, heating oils, oily fluids
- CSM/CM version: ≥ 100 mm (4 inch), preferred for many acids and lyes
- TPK version: ≥ 100 mm (4 inch), preferred for many acids and lyes

mounting:
- The float switch is mounted either from sidewards through a cable gland ≥ G1A into the vessel or
- by means of a counter weight or rods (e. g. float switch combination) from the top.
The pivot of the cable should always be horizontal.
