Owner manual
6. Paint or other contamination on the surfaces
of the equipment may cause high voltage
reduction and poor transfer eciency. A
schedule must be developed for equipment
maintenance (cleanliness). However, care
must be taken during cleaning. The electrode
needle must be straight and sharp. It is
recommended that the electrode tip be
cleaned using a mild solvent and a soft
bristle brush. Clean the exterior surfaces of
the Aerobell Copes as follows (see Warning
below).
a). All external surfaces may be cleaned
using a mild solvent and lint free rags to
hand wipe the Aero-bell Copes. 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. (See step #1.)
b). If conductive, polar solvents are used
to clean the Aerobell Copes unit all
residue must be removed using a non-
conductive non-polar solvent. (i.e., high
ash naphtha.) (See step #1.)
c). Do not spray the Aerobell Copes units
with a solvent gun used for cleaning.
The cleaning uid under pressure may
aid conductive materials to wick into
hard to clean areas or may allow uids
to be forced into the turbine assembly.
(See step #1.)
> To reduce the risk of re or explosion,
OSHA and NFPA-33 require that solvents used
for exterior cleaning be non-ammable (ash
points higher than 100°F / 37.8°C). Also, since
electrostatic equipment is involved, these
solvents should also be non-polar. Examples
of non-ammable, non-polar solvents for wipe
down are: amyl acetate, methyl amyl acetate,
high ash naphtha and mineral spirits.
VIBRATION NOISE
If the Aerobell Copes is vibrating or making an
unusually loud noise, it usually means there is an
imbalance situation. The atomizer bell may have
dried paint on it, or the bell may be physically
damaged, or there may be paint trapped between
the bell and shaft preventing the bell from properly
seating. If any of these conditions exist, they must
be corrected. Excessive imbalance caused by one
of these conditions may result in bearing damage
and turbine failure. Warranty does not cover failure
caused by imbalanced loading conditions.
To determine if the bell is dirty or damaged, remove
the bell and turn the turbine ON. If the noise is
eliminated, the bell is the problem. If the noise
continues, the turbine may be damaged and should
be inspected. Do not continue to operate a noisy
turbine.

7. Do not reuse an atomizer bell that shows signs
of damage such as nicks, heavy scratches,
dents, or excessive wear.
PREVENTIVE
MAINTENANCE
Daily Maintenance
• Due to the close proximity of high voltage to
ground potential, a schedule must be developed for
equipment maintenance (cleanliness).
• Paint within the applicator must be ushed from
the system prior to any down time or break in
production.
• Verify that high voltage is OFF and that shaping air,
bearing air and turbine drive air are ON.
• Open the solvent valve, ushing all paint from
the supply lines and through the atomizer bell
assembly.
