Setting the response pressure
1) Unscrew protective cap A
2) Adjustment (+) - Setting spindle B "turn clockwise" = increasing response pressure (setpoint) OR
3) Adjustment (-) - Setting spindle B "turn counter-clockwise" = reducing response pressure (setpoint)
4) Check setpoint
5) Screw on protective cap A
6) Attach lead seal
