ASSEMBLY PROCEDURES
(Refer to Figure 1)
1. Place Item 10 (o-ring) in the slot on Item 6
(lower diaphragm retainer).
2. Place Item 8 (lower diaphragm) on the lower
diaphragm retainer with the side of the diaphragm
contacting the retainer (o-ring side).
3. Stack the following parts on the lower dia-
phragm, in the following order:
• Item 7 (Center Diaphragm Retainer)
• Item 17 (Bleed Spacer)
• Item 14 (Center Diaphragm)
• Item 5 (Upper Diaphragm Retainer)
• Item 16 (Screw)
4. Ensure that clearance holes in Items 8 and
14 (diaphragms) and Item 17 (bleed spacer) are
aligned properly and tighten Item 16 (screw). Use
adhesive 222 on screw threads. Set this assembly
aside.
5. Place lower housing on table with bottom
threaded opening facing "UP".
6. Insert Item 10 (o-ring) and Item 11 (regulating
seat) into the lower housing. The beveled side
of the regulating seat must be "UP".
8. Place Item 10 (o-ring) on Item 13 (retaining
plug).
9. Place Item 12 (spring) into lower housing over
Item 11 (regulating needle) and thread Item 13
(retaining plug) into lower housing. Tighten Item
13 (retaining plug) ensuring that needle/spring
remains in the center of the lower housing.
10. Place lower housing on table with bowl facing
"UP" and place diaphragm assembly (from step 4),
with pin facing "DOWN". Rotate the diaphragm
assembly so that the slot on Item 6 (lower retainer)
is 180 o to the outlet port on the lower housing for
cleaner flushing of paint.
11. Place Item 2 (spacer ring) on the top of the
diaphragm assembly with largest opening facing
"DOWN". Rotate the spacer ring, without rotating
the diaphragm assembly, so that the inlet port of
the spacer ring is 90 o to the outlet port on the lower
housing and all the clearance holes are aligned
(see Figure 1).
12. Place Item 9 (diaphragm) on Item 2 (spacer
ring) and align holes.
13. Place Item 1 (cap) on diaphragm. Rotate
the cap, without rotating the diaphragm assembly,
so that the inlet port of the cap is 90 o from Item
2 (spacer ring) and 180 o from the outlet port on
the lower housing. Align holes and insert Item 4
(8-screws).
14. Tighten opposing screws alternately to 8
lbs•in, ensuring uniform sealing of the diaphragms.
Then follow by tightening each screw in a circle
pattern to 14-16 lbs•in.
7. Place Item 11 (regulating needle) into lower
housing with the ball end against Item 11 (regu-
lating seat).
