CAUTION – Before performing the next step retract the Poppet from the Adjustable Orifice by fully
depressing the Demand Lever. Rotation of the Adjustable Orifice without retracting the Poppet may
result in damage to the Poppet Seat necessitating replacement of the seat.
33. Install the Inlet Connector into the housing taking care to depress the demand lever fully to retract the poppet
to prevent contact with the adjustable orifice as the inlet fitting is rotated during insertion. Use a 3/4" (19mm)
wrench to tighten. (Apply approximately 40 in-lbs (4.5 N-m) torque).
34. Install a cleaned and lubricated O-ring (11) onto the Access Plug and insert the Access Plug into the
housing. Secure with the C-clip.
35. Remove the port plug from the Access Plug.
NOTE – The following information describes the recommended process for adjusting the Demand Lever
height. This process requires the use of the In-line Adjustment Tool (20-500-200).
36. Temporarily attach the partially assembled second stage to a fully assembled and adjusted first stage with an
intermediate pressure set at 140 +/- 10 psi (9.6 +/- 0.7 bar). Place the In-line Adjustment Tool 20-500-200
between the hose and the inlet connector.
