Atomizer Reassembly (Indirect Charge)
Make certain the quick disconnect retaining ring
is on the mounting manifold prior to installing any
tubes. Install all tubing to the appropriate port in
the mounting manifold. Ensure the ground cable
is properly secured into the plug before tightening
the compression nut.
Once the tubes are attached, secure the mounting
manifold to the robot with the four (4) screws.
Align the turbine manifold assembly with the
mounting manifold assembly and press firmly. A
slight press-fit is typical as O-rings engage.
White standing in front of the applicator, tighten the
quick disconnect retaining ring counter-clockwise.
Use of the spanner wrench to aid in tightening
may be necessary.
Check ground connection with an ohm meter.
Connect one lead of the meter to the shaft of
the air bearing spindle and the other lead to the
other end of the ground cable or the earth ground
source that it is connected to. Reading should be
10 ohms or less.
Remove the curved high voltage tube from the
high voltage ring. Slide the high voltage nut and
ferrules onto the high voltage cable, 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 high voltage locknut
(A11318-00) by hand. Ensure 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.
Proper high voltage cable installation may be veri-
fied by checking probe resistance from electrodes
to the end of the high voltage cable per the use of
an 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
152-168 megohms. If not, recheck connection in
the high voltage ring.

NOTE
† Before installing high voltage ring, fill
the cavity in the high voltage ring with di-
electric grease between the input and the
outer diameter (see “Atomizer Removal”
figure in the “Maintenance” section).
High Voltage Ring Removal / Replacement
(Indirect Charge)
Loosen the high voltage locknut (A11318-00)
and pull curved tube from back of high voltage
ring. Grasp the high voltage ring and turn count-
er-clockwise approximately 10-15”until locking
pins disengage. Pull ring forward to remove.
To reassemble, ensure O-ring on inside diameter
and on face of atomizer extension are seated
properly in their grooves. Lightly lubricate both
