The manifold assembly contains the following valves (refer to Fig. 18).
High-Pressure Relief Valve Cartridges
Charge Relief Valve
The O-ring should be placed in the port with the full counterbore. The O-rings and backup rings fit in the ports
with the machined grooves. The O-ring should be installed first and then the backup ring (refer to Fig. 19).
When installing the manifold on the end cap be certain the backup rings are properly installed and do not slip
out of the grooves (refer to Fig. 20).
