External Atomizer Surface Cleaning
Internal Fluid Path Cleaning
With the high voltage turned off and the disk spinning,
flush cleaning solvent through the incom-ing paint
line or through the solvent inlet line. If it is desired to
clean just the face of the disk off, flush solvent through
the solvent inlet. If a color change is required, flush
the entire system. The spinning disk will atomize the
solvent and clean out the disk passages. If equipped,
trigger the dump valve to catch the wasted paint from
the incoming line, then flush the disk with solvent
after closing the dump valve.
Disk Cleaning
Normally, the internal cleaning instructions will suf-
fice to clean the disk. If flushing the disk does not
remove all the residue, the disk may be removed for
hand cleaning. Unscrew mounting nut and remove
the disk by using the supplied disk puller.
> Solvent flushing of the system (except
during color change) should be done with
the disk dismounted and with waste solvent
collected in a grounded container.
NOTE
>
Do not hold disk edge during removal.
This could result in injury.

The turbine shaft must be held with a
7/16” open end wrench while using the disk
puller.
NOTE
> To reduce the risk of fire or explosion,
OSHA and NFPA-33 require that solvents
used for exterior cleaning, including disk
cleaning and soaking, be nonflammable
(flash points higher than 100
o
F/37.8
o
C).
Since electrostatic equipment is involved,
these solvents should also be nonpolar. Ex-
amples of nonflammable, nonpolar solvents
for cleaning are: Amyl acetate, methyl amyl
acetate, high flash naphtha and mineral
spirits.
> Do not use conductive solvents such as
MEK to clean the external surfaces of the
Turbodisk.
> Never lower the Turbodisk assembly into
a drum for flushing or color changing.

Never submerge a disk into a solvent
bath while still mounted on the shaft. Sol-
vent may intrude into bearing cavity and
destroy the grease. Remove disk to hand
clean or run disk and flush through trigger
and dump valves.
