Leave line loose in atomizer extension.
Remove the six (6) 6mm screws holding the
rear manifold to the atomizer extension using
a 5mm hex key. Slide the rear plate and cup
wash manifold assembly out. All the tubing
should come with the assembly except the fi-
ber optic and cup wash line.
Replacement:
To replace the cup wash manifold and rear
plate assembly, you must have all the tubing in
place on the cup wash manifold except the
fiber optic and the solvent wash line. Lightly
tape the tube ends together to ease installa-
tion. Slide the tubing into the atomizer exten-
sion, helping the tube make the bend at the
front end of the atomizer extension.
Align the locating pin and the rear plate with
the locating hole of the atomizer extension.
Install the six (6) 6mm socket head screws.
Tighten to 15 lbs.- in. (1.69 Nm) torque (see
Figure 35).
Reattach all tubing at the atomizer end; rein-
stall the fiber optic cable into the rear plate.
Tighten set screw to 10 lbs.- in. (1.13 Nm)
torque.
Install the mounting ring onto the atomizer ex-
tension, threads facing rearward. Install the
break-away ring. Align the four (4) locating
dowel pins with the corresponding four (4)
holes on the break-away ring. Install the six
(6) 1/4-20 stainless steel screws. Tighten to
15-20 lbs.- in. (17 - 2.3 Nm) torque. If you are
using the optional plastic break-away screws,
tighten evenly to 5 lbs.- in. (.56 Nm) torque.
The break-away ring must lie flat against the
face of the rear manifold.

break-away ring and the mounting ring will
now come off.
