Installation conditions | ||
Installation instructions |
range of application and minimum length between mounting and float: - PVC version: ≥ 50 mm (2 inch), preferred for water - 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 Float switches are fastened onto the lower end of the guide pipe in the factory. The position of the switch points required for the application must be adjusted by the user by moving the set collars (in some cases, it may be necessary to shorten the float switch wire). |
