Assembling the Manifold Valve
1. Check the condition of the outlet fitting O-rings
(section valve manifold only), endcap O-rings, back
seating O-rings, ball seat for damage or wear
and
Figure
94).
Note: Replace any damaged or worn O-rings or seats.
2. Apply grease to the valve stem and insert it into the
valve stem seat
(Figure 93
3. Install the valve stem and seat into the manifold and
