DISASSEMBLY PROCEDURES
(Cont.)
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 ca-
ble. 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 se-
curely by hand.
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 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 meg-
ohms. If not, recheck connection in the high
voltage ring.

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
counter-clockwise approximately 10-15”until
locking pins disengage. Pull ring forward to
remove.
To reassemble, ensure O-ring on inside diam-
eter and on face of atomizer extension are
seated properly in their grooves. Lightly lubri-
cate 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 required 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 between the input and
the outer diameter with dielectric grease (see
“Atomizer Removal” figure in the
“Maintenance” section).
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 se-
curely by hand. Proper high voltage cable in-
stallation can be verified by checking probe
resistance from the electrodes to the end of
the high voltage cable per 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
