Fire Hazard
Improper or inadequate oper-
ation and maintenance proce-
dures 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 pow-
er supply shutdown indicates a
problem in the system requiring
correction.
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 off prior to cleaning, ushing or main-
tenance.
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 solvents used for cleaning must have
a ash point at minimum of 5oC (9oF) greater
than the ambient temperature. It is the end
users responsibility to insure this condition is
met.
Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, country, and local
codes. In addition, ventilation must be main-
tained during cleaning operations using am-
mable or combustible solvents.
Electrostatic arcing must be prevented. Safe
sparking distance must be maintained between
the parts being coated and the applicator. A dis-
tance of 1 inch for every 10KV of output voltage
is required at all times.
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 unautho-
rized equipment modications may cause re or
injury.
If used, the key switch bypass is intended for
use only during setup operations. Production
should never be done with safety interlocks dis-
abled.
Never use equipment intended for use in water-
borne installations to spray solvent based ma-
terials.
The paint process and equipment should be
set up and operated in accordance with NFPA-
33, NEC, OSHA, local, country, and European
Health and Safety Norms.

Electrical
Equipment
High voltage equipment is uti-
lized. Arcing in areas of am-
mable or combustible mat-erials
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.
An electrical arc can ignite coat-
ing materials and cause a re or
explosion.
Turn the power module OFF before working on
the equipment.
Test only in areas free of ammable or combus-
tible 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 Ma-
terials
Halogenated hydrocarbon sol-
vents, for example: methylene
chloride and 1,1,1, - Trichlo-
roethane, are not chemically
compatible with the aluminum
that might be used in many sys-
tem components. The chemical
reaction caused by these sol-
vents reacting with aluminum
can become violent and lead to
an equipment explosion.
Spray applicators require that aluminum inlet ttings
be replaced with stainless steel. (See "Accesso-
ries" list) Aluminum is widely used in other spray
application equipment - such as material pumps,
regulators, valves, etc. Check all other equipment
items before use and make sure they can also be
used safely with these solvents. Read the label
or data sheet for the material you intend to spray.
If in doubt as to whether or not a coating or clean-
ing material is compatible, contact your material
supplier. Any other type of solvent may be used
with aluminum equipment.
Certain material may be harmful
if inhaled, or if there is contact
with the skin.
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 pre-
scribed by an industrial hygienist or safety expert,
and be approved.

Vector Solo AA90 Applicators - Introduction
Ransburg

AH-08-04.2
GENERAL DESCRIPTION
The Vector SoloTM AA90 Applicators are a com-
bined air/airless powered only by a pressurized
air source. Pressurized air creates rotation of a
turbine generator that powers a cascade. The
cascade generates a high voltage DC charge
to the electrode creating an electrostatic eld
between the atomizer and the target. The target
is electrically grounded through its support which
may be either stationary or moving.
A regulated pressure uid system delivers coating
material to the atomizer. At the time of triggering
the applicator, fan and atomization air is introduced,
which atomizes the coating material into a spray
mist. The atomized spray particles under the inu-
ence of the electrostatic eld become electrically
charged. The charged particles are attracted to,
and deposited on, the target object. The forces
between the charged particles and the grounded
target are sufcient to turn most normal overspray
around and deposit it on the back surface of the
target. Therefore, a high percentage of the coating
is deposited on the target.
One of the many features of the VectorSolo AA90
applicator system is that the electrical energy,
which is available from the resistive charging
electrode, is limited to the optimum level of safety
and efciency. The system is incapable of releas-
ing sufcient electrical or thermal energy during
normal operating conditions to cause ignition of
specic hazardous materials in their most easily
ignited concentrations in air.
As the applicator electrode approaches ground,
applicator circuitry causes the high voltage to
approach zero while the current approaches its
maximum value.

Air Hose
For the Vector Solo AA90 to properly function
safely, the 79727-XX Air Hose assembly with
ground wire is required to be used.
Fluid Hose Recommendation
Ransburg recommends using a 7994-XX Fluid
Hose Assembly. This assembly is made to spe-
cically t the uid tting size engineered into the
applicator. This hose is available as a standard
conguration or as a replacement from your au-
thorized Ransburg distributor.
Any user installed uid hose used must
be rated for 207 bar (3000 psig) working
pressure minimum.
C A U T I O N
!
Filters
1. Install an air lter assembly on the outlet of the
main air regulator. The lter should be 5 micron
with a maximum working pressure of at least
100 psig (6.9 bar). Screw the tting into the lter
inlet. The lter MUST be installed with the arrow
pointing in the direction of ow. (Refer to the ap-
propriate Filter Assembly manual for Installation
Instruc-tions.)
2. Ransburg recommends that a uid lter be
installed at the output of the uid supply (pump,
circulating system, etc.). It is the end user's re-
sponsibility to install the proper lter that meets
their system's requirements.

Interlocks Required
Interlock the solvent supply with the main supply
air to the applicator. When solvent is On, main
supply air to the applicator is Off. Interlocks are
user supplied.
The solvent supply must be interlocked
with applicator supply air. Supply air must be
off to the applicator when solvent supply is on.

SAFE OPERATION
• Ground all operators by requiring that they hold
the applicator handle with a bare hand.
• Ground operators and all other persons in spray
areas by requiring that they wear conductive
soled shoes or grounding straps.
• Have exhaust fans operating while spraying.
• Exhaust fans must be interlocked with the at-
omization air.
• See that no more than one gallon of solvent per
safety container per operator is inside of the
hazard location.
• If ANY symptom of improper operation occurs,
suspend use of the unit until the problem has
been diagnosed and corrected. See "Trouble-
shooting Guide" in the "Maintenance" section
or contact your authorized Ransburg repre-
sentative.
• Ground MUST be maintained during the addi-
tion of uid to any supply container! Whenever
transferring ammable uid from one container
to another, both containers MUST be properly
connected to a proven ground rst and then to
each other. Personnel executing such a transfer
MUST also be grounded.
• A chemical reaction resulting in the possibility
of a pressure EXPLOSION, may occur if 1,
1, 1-Trichloroethane, Methylene Chloride, or
other Halogenated Hydrocarbon solvents are
used in PRESSURIZABLE FLUID SYSTEMS
having ALUMINUM or GALVANIZED WETTED
PARTS. Such an explosion could cause DEATH,
serious BODILY INJURY and/or substantial
property damage. Consult your uid supplier to
determine the chemical content of your solvents.
(See "HHC Explosion Hazard Danger Sign" and
"Halogenated Hydrocarbon Safety Bulletin".)
• Never ush the applicator with solvent while
electrostatics are on. Failure to turn off electro-
statics while ushing may cause an IGNITION
HAZARD. Applicator supply air must be inter-
locked with solvent supply.

ing upon amount of air required to eliminate the
tails. Minimum pressure is 2.75 bar (40 psig) at the
handle. Use either gauge from Maintenance and
Test Kit or use Table I to use a gauge reading at
the wall regulator adjusted for the pressure drop
in the air hose.
