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.
