Aerobell Copes - Maintenance
MAINTENANCE
In addition to the above Warning, which relates to
potential safety hazards, the following information
must be observed to prevent damage to the
equipment.
> Electrical shock/arcing and potential fire
hazards can exist during maintenance. The
high voltage must be turned OFF before enter-
ing the spray area and performing any mainte-
nance procedures. Spray booth exhaust fans(s)
should remain ON while cleaning the equip-
ment with solvents.
> Never touch the atomizer bell while it is
spinning. The front edge can easily cut into
human skin. Make sure the atomizer bell has
stopped spinning before attempting to touch
it. Wait at least three minutes after turbine
drive air is OFF before touching the bell.
The precise sequence of flushing paint from the
system will vary according to the type of color valve
arrangement used and other automatic features
built into the system. Follow these basic procedures
when cleaning:

CLEANING PROCEDURES 1. Verify high voltage is OFF. The high voltage
must be turned OFF before performing any
maintenance.
2. With the bearing air and turbine air ON, flush
paint out with solvent. Flushing should be
done before any break in production. If
the Aerobell Copes is mounted facing up,
rotate to a horizontal plane before flushing
or cleaning.
3. Flushing should be done with the atomizer
bell installed. The bell includes a self cleaning
feature, and the bell will normally be fully
cleaned with flushing. However, if there is any
remaining paint build up on any areas of the
bell after flushing, the bell should be removed
and cleaned by hand (see 4 below).
4. Clean the bell by soaking in an appropriate
solvent as long as necessary to loosen paint.
Use a soft bristle brush dipped in solvent to
remove paint. Make sure all signs of paint are
removed. See Caution below. Rinse and dry
bell.
5. Before re-installing the bell onto the shaft,
check the tapered mating surfaces of the
turbine shaft and bell for any paint residue.
Clean any residue. See Caution below.

W A R N I N G !
> Do not immerse the Aerobell Copes
turbine in solvent or other liquids. Turbine
components will be damaged.
> Bearing air must be ON during all cleaning
procedures.
> Do not spray the Aerobell Copes unit with
a solvent gun for cleaning. Dousing or spray-
ing the applicator and Aerobell Copes compo-
nents with solvent before wiping will not help
to loosen paint.
C A U T I O N !
> Using an atomizer bell with paint build up
will cause a bell imbalance. An imbalanced
bell may cause bearing damage and turbine
failure. Also, any paint residue caught between
the tapered surfaces can prevent the bell from
seating properly and result in an imbalanced
condition.
> Never install an atomizer bell onto the
shaft without cleaning the fluid tube tip. Paint
build-up on the tip may get caught in the
thread relief of the bell during installation.
