> The maximum flow rate of 700 cc/min. must
not be exceeded during a flush routine. Use
of an in-line fluid restrictor is recommended.
External Atomizer Surface Clean-
ing
•
Verify that the high voltage is turned off.
•
All external surfaces may be cleaned us-
ing a mild solvent and lint free rags to
hand wipe the RMA-303 Turbine drive air
must be off, but leave bearing air on. The
inner and outer shaping air should have
approximately 70 slpm air flow through
each to prevent the solvent from entering
these passages.
•
Always final wipe all parts with a non-polar
solvent and wipe dry (high flash Naphtha,
etc.).
•
Do not spray the RMA-303 unit with a sol-
vent applicator used for cleaning. The
cleaning fluid under pressure may aid con-
ductive
•
Materials to work into hard to clean areas
or may allow fluids to be forced into the
turbine assembly.
•
Do not reuse an atomizer bell cup that
shows any sign of damage such as nicks,
heavy scratches, dents, or excessive
wear.
•
For best operating conditions, the atomizer
surfaces must be dry.
> NEVER wrap the applicator in plastic to
keep it clean. A surface charge may build up
on the plastic surface and discharge to the
nearest grounded object. Efficiency of the
applicator will also be reduced and damage or
failure of the applicator components may oc-
cur. WRAPPING THE APPLICATOR IN
PLASTIC WILL VOID WARRANTY.
> To reduce the risk of fire or explosion,
OSHA and NFPA-33 require that solvents
used for exterior cleaning, including bell
cleaning and soaking, be nonflammable (flash
points higher than 100
o
F/37.8
o
C). Since elec-
trostatic equipment is involved, these solvents
should also be non-polar. Examples of non-
flammable, non-polar 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
RMA-303 without a second cleaning with a
non-polar solvent.
> When using a rag to hand wipe the RMA-
303, the turbine air should be off, but leave
both the shaping air and bearing air turned
on. Insure that rotation has come to a com-
plete stop.
