Before operating, maintaining or servicing any
Ransburg electrostatic coating system, read and
understand all of the technical and safety literature
for your Ransburg products. This manual contains
information that is important for you to know and
understand. This information relates to USER SAFETY
and PREVENTING EQUIPMENT PROBLEMS. To help
you recognize this information, we use the following
symbols. Please pay particular attention to these
sections.
A WARNING! states information to alert you to a
situation that might cause serious injury if instructions
are not followed.
A CAUTION! states information that tells how to
prevent damage to equipment or how to avoid a
situation that might cause minor injury.
A NOTE is information relevant to the procedure in
progress.
While this manual lists standard specications and
service procedures, some minor deviations may be
found between this literature and your equipment.
Dierences in local codes and plant requirements,
material delivery requirements, etc., make such
variations inevitable. Compare this manual with
your system installation drawings and appropriate
Ransburg equipment manuals to reconcile such
dierences.
!
W A R N I N G

AREA
Tells where hazards
may occur.
Spray Area
HAZARD
Tells what the hazard is.
Fire Hazard
Improper or inadequate
operationing and maintenance
procedures will cause a re hazard.
Protection against inadvertent
arcing that is capable of causing
re or explosion is lost if any safety
interlocks are disabled during
operation. Frequent power supply
shutdown indicates a problem in
the system requiring correction.
SAFEGUARDS
Tells how to avoid the hazard.
Fire extinguishing equipment must be present in the
spray area and tested periodically.
Spray areas must be kept clean to prevent the
accumulation of combustible residues.
Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must be
turned o prior to cleaning, ushing or maintenance.
When using solvents for cleaning:
Those used for equipment ushing should have ash
points equal to or higher than those of the coating
material.
Those used for general cleaning must have ash
points above 100°F (37.8°C).
Spray booth ventilation must be kept at the rates
required by NFPA 33, 1995 Edition, OSHA and local
codes. In addition, ventilation must be maintained
during cleaning operations using ammable or
combustible solvents.
General Use and
Maintenance
Improper operation or
maintenance may create a hazard.
Personnel must be properly
trained in the use of this
equipment.
Electrostatic arcing must be prevented.
Test only in areas free of combustible material.
Testing may require high voltage to be on, but only as
instructed.
Non-factory replacement parts or unauthorized
equipment modications may cause re or injury.
If used, the key switch by-pass is intended for use
only during set-up operations. Production should
never be done with safety interlocks disabled.
Never use equipment intended for use in waterborne
installations to spray solvent based materials.
Personnel must be given training in accordance
with the requirements of NFPA-33, Chapter 16, 1995
edition.
Instructions and safety precautions must be read and
understood prior to using this equipment.
Comply with appropriate local, state, and national
codes governing ventilation, re protection,
operation maintenance, and housekeeping. OSHA
references are Sections 1910.94 and 1910.107. Also
refer to NFPA-33, 1995 edition and your insurance
company requirements.

HAZARD
Tells what the hazard is.
High voltage equipment is
utilized. Arcing in areas of
ammable or combustible
materials may occur. Personnel
are exposed to high voltage
during operation and
maintenance.
Protection against inadvertent
arcing that may cause a re or
explosion is lost if safety circuits
are disabled during operation.
Frequent power supply shut-down
indicates a problem in the system
which requires correction.
An electrical arc can ignite coating
materials and cause a re or
explosion.
SAFEGUARDS
Tells how to avoid the hazard.
The power supply, optional remote control cabinet,
and all other electrical equipment must be located
outside Class I or II, Division 1 and 2 hazardous areas.
Refer to NFPA No. 33, 1995 Edition.
Turn the power supply OFF before working on the
equipment.
Test only in areas free of ammable or combustible
material.
Testing may require high voltage to be on, but only as
instructed.
Production should never be done with the safety
circuits disabled.
Before turning the high voltage on, make sure no
objects are within the sparking distance.
Explosion Hazard /
Incompatible
Materials
Toxic Substances
Halogenated hydrocarbon solvents
for example: methylene chloride
and 1,1,1,-Trichloroethane are not
chemically compatible with the
aluminum that might be used in
many system components. The
chemical reaction caused by these
solvents reacting with aluminum
can become violent and lead to an
equipment explosion.
Certain material may be harmful if
inhaled, or if there is contact with
the skin.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum
equipment during spraying, ushing, or cleaning.
Read the label or data sheet for the material you
intend to spray. If in doubt as to whether or not a
coating or cleaning material is compatible, contact
your material supplier. Any other type of solvent may
be used with aluminum equipment.
Follow the requirements of the Material Safety Data
Sheet supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the air
free of accumulations of toxic materials.
Use a mask or respirator whenever there is a chance
of inhaling sprayed materials. The mask must be
compatible with the material being sprayed and its
concentration. Equipment must be as prescribed by
an industrial hygienist or safety expert, and be NIOSH
approved.

HAZARD
Tells what the hazard is.
This is a high voltage ungrounded
device that can produce electrical

SAFEGUARDS
Tells how to avoid the hazard.
Parts being sprayed must be supported on conveyors or
hangers and be grounded. The resistance between the
part and ground must not exceed 1 megohm. (Reference
NFPA Bulletin No. 33, 1995 Edition.)
A safe distance must be maintained between the parts
being coated and the atomizer bell. A distance of at least
1 inch for each 10 KV of power supply output voltage
is required at all times.
Parts must be supported so that they will not swing and
reduce the clearance specied above.
All electrically conductive objects in the spray area, with
the exception of those objects required by the process
to be at high voltage, must be grounded.
Unless specically approved for use in hazardous
locations, the power supply and other electrical
equipment must not be used in Class I, Division 1 or
2 locations.

Using coating materials and/or
cleaning and ushing solvents
which have ash points below
100°F (37.8°C) may cause a re

Aerobell Copes - Introduction
INTRODUCTION
GENERAL DESCRIPTION
Aerobell Copes is a indirect (external) charging
electrostatic applicator for use with grounded
waterborne fluid systems. Indirect charging,
known as ion bombardment, is a proven method
of electrostatically charging waterborne material
without the need of isolating the uid system.
High voltage is applied to the six probes (electrode)
assemblies located on the exterior of the bell assembly.
Paint is atomized by the ground-ed bell cup and the
electrostatic charge is applied to the atomized paint
particles during the transfer to a grounded work
piece via the electrostatic eld generated from the
six probes.
FEATURES
• Aerobell quick change turbine motor.
• Retaining nut for fast replacement of the rotary
atomizer assembly.
• Center mounting of rotary atomizer.
• Indirect (external) charge for use with grounded,
waterborne systems.
• Optional direct charge for use with isolated,
waterborne systems (electrodes removed).
• Optional direct charge for use with grounded,
solventborne systems (electrodes removed).

AIR FILTRATION
REQUIRMENTS
It is the user's responsibility to insure clean, dry air at
all times. Turbine failure resulting from contaminated
air will not be covered under warranty. The following
pre-lter and bearing air lter(s) (see Figure 5) are
recommended for use in Aerobell Copes systems. See
Figure 5 if other lters are incorporated in the system
- the lters to be used must have ltering capacities
equal to or greater than those shown in Figure 5.

> Air must be properly ltered to assure ex-
tended turbine life and to prevent contamination of the paint job. Air which is not adequately
ltered will foul the turbine air bearings and cause
turbine failure. The correct type of lters must
be used in an Aerobell Copes system. The lter
elements must be replaced on a regular schedule
to assure clean air.
