Troubleshooting & Repair Procedures
RP16 - Vent Valve RR
1) Remove the covers (RP4).
2) Use a 9/16 inch open-end wrench to disconnect the 1/4inch
tube nut that connects the vent extension tube to the vent
valve (Figure 19).
Figure 19: Vent Extension Tube Removal
3) Use a 9/16inch open-end wrench to disconnect the 1/4 inch
tube nut that connects the long vent tube to the vent valve
(Figure 20).
Figure 20: Vent Tube Removal
4) Use a 5/8inch open-wrench on the vent valve body hex
flats to hold the body stationary. Use a 11/16 inch open end
wrench to loosen the jam nut that holds the vent valve to the
mounting bracket (Figure 21).

5) Slide the vent valve out of the mounting bracket.
6) Position the new vent valve in the mounting bracket slot. Do
not tighten the jam nut at this time.
NOTE: The mounting bracket should be between the jam nut and
the valve body hex flats. The valve flow direction arrow should
point downward.
7) Align the short vent tube and long vent tube with the proper
vent valve ports. Thread the tube nuts onto the valve and
tighten.
NOTE: Do not over tighten the vent tube nuts. Over tightening
may result in a cracked fitting. Only a slight increase in torque
is required to seal up a compression fitting that has already been
made up. For 1/2 inch tubing, 1/4 turn from finger-tight is re-
quired when making up a new fitting.
8) Push the vent valve fully into the slot in the mounting
bracket. Hold the valve in this position with a 5/8 inch open-
end wrench placed on the valve body hex flats. Use a 11/16
inch open-end wrench to tighten the jam nut.
NOTE: Check for proper vent valve lever operation after install-
ing the side cover. Adjust the vent valve horizontally by shifting
the valve in the mounting bracket. Adjust vertically by loosening
the two socket head cap screws mounted in the tabs on the bottom
of the bottle and shifting the entire bottle assembly up or down.
Make sure that the vent extension tube outlet is centered in the
corresponding side cover clearance hole.
9) Install the side covers (RP4).
