To reassemble, insure o-ring on inside diame-
ter of the high voltage ring and on face of at-
omizer extension are seated properly in their
grooves. Lightly lubricate both O-rings with
A11545-00 petrolatum jell. Slide high voltage
ring onto atomizer body making sure high
voltage input is located at the top of the unit.
Push firmly until it stops against the atomizer
extension and is engaged on the locking pins.
Rotate high voltage ring clockwise 10-15° to
lock ring into place. Some force may be re-
quired with a new ring, but a solid lock will be
felt when properly installed.
> Before installing high voltage ring, fill the
cavity in the high voltage ring with dielectric
grease between the input and the outer diam-
eter).
Before installing the curved tube, ensure the
outer ring of the high voltage input is filled
with new dielectric grease. Reinstall high
voltage cable and curved tube and tighten
locknut securely by hand. Proper high volt-
age cable installation can be verified by
checking probe resistance from the elec-
trodes to the end of the high voltage cable per
use of a Yakogawa megohm meter or equiva-
lent. Attach one lead to the end of the high
voltage cable and touch the other end to the
wire at the top of each electrode, one at a
time. The reading should be per "Chart A". If
not, recheck connection in the high voltage
ring.

Atomizer Reassembly
Rear shroud halves must be removed for at-
omizer reassembly. Insert the high voltage
cable through the center hole of the atomizer
and feed the banana jack end through the
hole in the atomizer extension. Once the ca-
ble is through, slide the applicator towards the
robot plate and align the two guide pins with
the holes in the robot plate. Push the atomiz-
er to the robot plate until both plates are flush.
Engage the mounting ring and tighten secure-
ly. Remove the curved high voltage tube from
the high voltage ring. Slide the high voltage
nut and ferrules onto the high voltage cable,
and then slide the curved tube over the high
voltage cable. Leave assembly loose. Insert
the banana jack end of the cable into the rear
opening in the high voltage ring until it seats
firmly. Slide the curved tube towards the high
voltage ring and secure in place by tightening
the large locknut (A11318-00) by hand. Insure
high voltage cable is in place before tightening
high voltage nut and ferrule (78441-00) by
pushing high voltage cable towards the high
voltage ring. Tighten nut and ferrule securely
by hand. Reinstall rear shroud halves. Tight-
en screws 3-5 lbs.- in. (.34-56 Nm) torque.
Proper high voltage cable installation may be
verified by checking probe resistance from
electrodes to the end of the high voltage cable
per the use of a Yakogawa megohm meter or
equivalent. Attach one lead to the end of the
high voltage cable and touch the other end to
the wire at the tip of each electrode, one at a
time. The reading should be per "Chart A". If
not, recheck connection in the high voltage
ring.
High Voltage Ring Removal/Replacement
Loosen the high voltage locknut (A11318-00)
and pull curved tube from back of high voltage
ring. Grasp the high voltage ring and turn
counter-clockwise approximately 10-15° until
locking pins disengage. Pull ring forward to
remove.
