Procedure:
1. Secure the manifold by its center portion, in a bench vise, with the valve knobs pointing upward.
2. Using the .061" hex wrench, loosen and remove the knob inserts (4), as well as, the nylon washer (33)
from the pressure and vent valve stems.
3. Using the .050" hex wrench, loosen and remove the setscrew (34) and lock nut (2).
4. Loosen the 3/4" lock nuts (1) on the COARSE (inlet pressure) and VENT valve threaded needle housings
(10).
5. Using the needle housing socket (65580) and socket wrench, loosen and remove the needle/housing
assembly (10,11).
6. To disassemble the ISOLATION valve(s), first remove the valve needle (18) by turning the gear (6)
clockwise.
7. Loosen and remove the valve housing(s) (19) using the isolation valve housing removal socket (68509),
and socket wrench.
8. Remove the valve stem seat(s) (8) and valve needle seat(s) (9) by using the needle-nose pliers.
9. Remove the inner and outer O-ring(s) (28, 27) and back-up ring(s) (31, 30) from the valve stem seats and
wash all parts in solvent.
10. To remove valve seats (7) from either the COARSE (inlet pressure), VENT or ISOLATION valve(s), try
blowing compressed air through the inlet and outlet fittings. Otherwise, the center holes have to be
drilled and a tap used to extract the seat (steps 11-14).
