4. Turn the trim-pot until the yellow control lamp just switches off.

NOTE: Turning the trim-pot to the left decreases the switching sensitivity; turning it to the right increases the switching sensitivity.

5.Fill the dosing station until the level probe is two-thirds covered. The yellow control lamp should now switch on again. If not, repeat Step 4.

6.Reinstall the plastic screw (M3).

NOTE: The sliding switch under the cover must be set on “0”.
