XS Compact 2nd stage:
calibration steps
• Once the correct depth of the valve nozzle has been adjusted, you can
proceed with final calibration, adjusting the height of the valve flow lever;
• This move is performed with the regulator under pressure, connecting the 2nd
stage to a properly calibrated first stage with an intermediate pressure hose;
• Insert a 5.5 mm socket screwdriver (HZ 709009) into the side opening and
rotate the valve nut clockwise (+) until the regulator starts flowing gently;
• Then rotate the calibration nut counter-clockwise (-) until flow stops, and then
continue a bit further to ensure short length of idle travel for the lever;
• Correct calibration of the XS Compact stage is achieved when, with the
regulator under pressure, the lever has a short length of idle travel, about 1.5
- 2 mm from the diaphragm plate.
