MAINTENANCE MAINTENANCE MAINTENANCE MAINTENANCE MAINTENANCE
In addition to the above "Warning", which re-
lates to potential safety hazards, the following
information must be observed to prevent dam-
age to the equipment.
> Electrical shock and fire hazards can
exist during maintenance. High voltage
supply must be turned off before entering
the spray area and performing any main-
tenance procedures on the atomizer.
Spray booth fans should remain on while
cleaning with solvents.
> Never touch the atomizer bell while it
is spinning. The front edge of the bell can
easily cut into human skin or cut through
gloves and other materials. Be sure the
atomizer bell has stopped spinning before
attempting to touch it. Approximate time
for the bell to stop spinning after turning
off turbine drive air is three minutes.
> Do not not not not not immerse the Aerobell M turbine
in solvent or other liquids. Turbine compo-
nents will be damaged.
> Bearing air must be on during all
cleaning procedures to protect the air
bearing components.

Cleaning the incoming paint line (from paint
supply source such as color manifold through
the fluid valve block and bell assembly):
Turn off high voltage and turn on the trigger
valve. With the bell spinning, flush cleaning sol-
vent through the incoming paint line and through
the manifold passages, through the fluid tube
and onto the bell. The spinning bell will atomize
the solvent and clean out the bell passages. If
desired, open the dump valve to flush through
the dump line for a faster and contained system
flush.

Turn off the high voltage and trigger valve. With
the bell spinning, turn on the solvent valve to al-
low cleaning solvent to flow through the mani-
fold passages, through the fluid tube, and onto
the bell. The spinning bell will atomize the sol-
vent and clean out the bell passages.
With the solvent valve open, open the dump
valve to clean the remaining manifold fluid pas-
sage and to flush the dump line if desired.

• Verify that the high voltage is turned off.
• All external surfaces may be cleaned using a
mild solvent and lint free rags to hand wipe the
Aerobell M. Turbine drive air must be off, but
leave shaping air and bearing air on. Be careful
not to drip solvent into the opening behind the
bell.
• If conductive, polar solvents are used to
clean the Aerobell M unit, all residue must be
removed using a nonconductive nonpolar sol-
vent (ex., high flash naphtha).
• Do not spray the Aerobell M unit with a sol-
vent gun used for cleaning. The cleaning fluid
under pressure may aid conductive materials to
wick into hard to clean areas or may allow fluids
to be forced into the turbine assembly.
• Do not reuse an atomizer bell that shows
signs of damage such as nicks, heavy
scratches, dents, or excessive wear.
