† Fluid pressure must be shut off and pres-
sure relieved by actuating the valves prior to
removal.
!
† When reinstalling the resistor module,
care should be taken to avoid damage to the
high voltage tube. Also, make sure the rear
of the resistor module is properly seated in
the pocket before sliding the rear shroud for-
ward. If the resistor housing is not proper-
ly seated and the rear shroud is forced into
place, damage can occur to the rear shroud.

† The four screws holding in the regula-
tor are held captive. They do not back out
completely of the regulator.
NOTE
Rear Shroud Removal
The rear shroud (Figure 16a, item 33) can be
removed for cleaning or inspection of the com-
ponents on the inside of the assembly
Loosen the two captive screws (Figure 16a, item
28) by turning them inward (clockwise). Slide the
shroud backward over the hoses and high voltage
cable. Note that it is not necessary to remove
the shroud completely from the hoses. Slide it
backward (over the hoses) for easy accessibility
to the components such as valves.
If space parameters require that the spacing be-
tween the rear bulkhead and the mounting bar
be less than the recommended 10 to 12 inch,
the Aerobell 33 can be swiveled on the insulator
support so the rear shroud can be slid back fully.
If the outside or inside surfaces of the shroud are
dirty, wipe clean with a solvent damp rag.
Resistor Module Removal
To remove the high voltage cable from the resistor
module, first remove the retaining screw (Figure
16a, item 21) and slide the connector cover (Figure
16a, item 20) back over the cable. Then loosen
the strain relief nut and pull the cable straight out
of the module.
To remove the resistor module (Figure 16a, item
22), follow the procedures for removal of the rear
shroud. Then slightly lift the rear of the module
to clear the step in the rear bulkhead (Figure 17,
item 12), and slide it backward until completely
separated from the forward high voltage tube
(Figure 16a, item 6).
Fluid Regulator Removal
To remove the fluid regulator (Figure 16a, item
18) follow the procedures for removal of the rear
shroud. Then disconnect the air pilot lines at the
regulator, and the output fluid line at its connection
into the fluid manifold assembly (Figure 16a, item
7). Disconnect the fluid supply line at the regulator
inlet port, loosen the retaining screws, and pull the
regulator straight out of the bulkhead.
Fluid Manifold Valve Removal
To remove the fluid manifold assembly (Figure
16a, item 7) follow the procedures for removal of
the rear shroud. Then disconnect the air pilot lines
at the tube connection of each individual valve.
Disconnect all fluid connections including the
dump line, paint, and solvent supply lines from
the fluid manifold. Then using a medium flat
head screwdriver, remove the mounting screws
(Figure 16a, item 9) and pull the manifold straight
back to separate it from the fluid tube. To remove
each individual fluid valve from the manifold use
a 7/8 open-end wrench, and turn the valve CCW
to disengage the threads. Then pull the valve
straight out of the manifold.
