By hand, attach the rear plate to the rear valve
manifold using the three (3) mounting screws. Do
not fully tighten. The rear plate is designed such
that it mounts to the rear valve manifold only one
way. Pull the assembly into the proper position
based on the position of the single air tube and
the single hole for the air tube in the rear valve
manifold. Pull the coiled tube fitting and ferrules
into the port for fluid and tighten clockwise into
place. Hand tighten until stop, then tighten 1/2-3/4
turn with a wrench. Attach the cup wash fitting
and ferrule in the cup wash port and tighten into
place. Hand tighten until stop, then tighten 1/8-
1/4 turn more with a wrench. Push the cascade
connector into the hole in the rear plate for it.
Align the timing mark on the plate with the timing
mark on the connector using a 3/32" wrench (see
Figure 45).
Tighten the set screw in place. Tighten to 10 lbs•in
(1.13 Nm) torque. Align the flat of the fiber optic
cable perpendicular to the set screw. Tighten
the set screw with a 3/32" wrench. Tighten to 10
lbs•in (1.13 Nm) torque. Install the five (5) air bolts
by hand. Tighten each bolt in a circular pattern.
Tighten the three (3) rear plate mounting screws
using a 3/16" wrench, 15 lbs•in torque (1.70 Nm).

Rear Manifold Removal
Remove the rear manifold from the applicator
(see "Cascade Removal/Replacement" in the
"Maint-enance" section). Inspect the valve weep
ports on the manifold body for leaks or contami-
nation. If any paint is visible in these areas, the
valves need to be replaced.
