Take off cover at switch compartment.
.
Pull off indicator disc.
.
Turn potentiometer (R) counter-clockwise until stop is felt. End position
CLOSED corresponds to 0 %, end position OPEN to 100 %.
.
Turn potentiometer (R) slightly back from the stop.
.
Perform fine-tuning of the zero point at external setting potentiometer (for
remote indication).
.
Press indicator disc on shaft and perform setting as described on page
.
Clean sealing faces at cover and housing; check whether O-ring is in good
