Bell Cleaning
Normally, the internal cleaning instructions will
suffice to clean the bell. If the internal cleaning
instructions does not sufficiently remove all
paint and residue from the bell, the bell may be
removed for hand cleaning.
> 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 electrostatic equipment is involved,
these solvents should also be nonpolar.
Examples 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 Aerobell M.
> When using a rag to hand wipe the
Aerobell M, the turbine air should be off
but leave the shaping air and bearing air
turned on. Ensure the rotation has come
to a complete stop. Be careful not to drip
solvent into the opening behind the bell.

NEVER wrap the applicator, associ-
ated valves and tubing, and supporting
hardware 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 appli-
cator will also be reduced and damage or
failure of the applicator components may
occur.

Clean the bell by soaking in an appropriate
solvent to soften paint residue. Do not soak for
more than a 24 hour period. Use a soft cloth to
remove the paint and a soft tool like a toothpick
to clean the paint holes. Be sure that all signs
of paint are removed. Rinse and dry the bell.
> It may be advantageous to develop a
maintenance schedule for hand cleaning
and inspection of the atomizer bell cup.

which would adversely affect transfer

> Do not use abrasive materials which
will scratch or damage the bell.
> Before reinstalling the bell onto the
shaft, check and clean the tapered mating
surfaces of the turbine shaft and bell for
any paint residue.
Using an atomizer bell with paint buildup
may cause a bell imbalance. An imbal-
anced bell may cause bearing damage
and turbine failure when operating at high
speeds. Excessive paint residue caught
between the internal tapered surface
which seats in the motor shaft can prevent
the bell from seating properly and result in
an unbalanced turbine condition.
