Any residual solvents would be contained in
the “J bend “ of the robot wrist.
All O-rings described in the “Maintenance”
section of this manual should be lubricated
with a food grade petroleum jelly or with
A11545 lubricant.

Direct Charge and Indirect Charge Atomizer
removal instructions are the same with the ex-
ception of removing the high voltage ring.
Disassembly the turbine manifold assembly
from the mounting manifold assembly by un-
screwing the retaining ring counter-clockwise.
Use of the spanner wrench to aid in removal
may be necessary.
Once the high voltage ring and turbine mani-
fold assembly have been disassembled, re-
move all tube connections to the mounting
manifold and remove the four (4) mounting
screws.
Atomizer Reassembly (Indirect Charge)
Make certain the quick disconnect retaining
ring is on the mounting manifold prior to in-
stalling any tubes. Install all tubing to the ap-
propriate port in the mounting manifold. En-
sure 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, tight-
en 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.
NOTE - Before installing high voltage ring, fill
the cavity in the high voltage ring with dielec-
tric grease between the input and the outer
diameter (see “Atomizer Removal” figure in
the “Maintenance” section).
