ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Overview of the ESS Model 350VA 32
Air-Assisted Electrostatic Sprayer
Air-assisted electrostatic sprayers produce electrically charged spray
drops that are carried to the plant canopy in a low pressure, gentle, air
stream. The heart of the 350VA32 Sprayer is the patented MaxCharge™
nozzle.
Air and liquid enter separately at the rear of the nozzle. Just before
leaving the nozzle, the air hits the liquid stream to make many thou-
sands of tiny spray droplets that pass through the charging ring. An
electrical charge is applied to the spray droplets by the charging ring.
Then the charged spray droplets are blown out of the nozzle and
move into the plant canopy where they are attracted to plant material
by electrostatic forces. The electrostatic charge induced by the Max-
Charge™ nozzle is strong enough to allow the droplets to move in any
direction to cover all plant surfaces, even defying gravity to coat the
underside of leaves and the back side of fruits and vegetables. The re-
sult is uniform spray coverage on hidden areas deep inside of the plant
canopy where other sprayers miss.
The MaxCharge™ nozzle is easy to clean and corrosion-proof. The inte-
rior ceramic outlet resists wear three times better than stainless steel
outlets. These features combine to give the best spray coverage on the
market. This quality product is virtually maintenance-free, and assures
you of savings in the application of chemical.
The comparison of air-assisted electrostatic spraying versus conven-
tional spraying is dramatic.
Electrostatically charged droplets are
attracted to plant surfaces.
Where Does the Spray Go?
The University of California completed a series of tests to investi-
gate what happens to spray liquid after it leaves the nozzle.
Conclusion: ESS technology places over 4 times the amount of
spray onto the plant surface using ½ the amount of chemicals.
Furthermore, they also reported that ESS sprayers send ⁄ less
chemicals to the ground and into the air. Less chemical used
overall, less waste and less drift than conventional equipment.
Imagine the environmental benet!

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Installing the Sprayer for the First Time
The 350VA32 sprayer is fully assembled and tested at Electrostatic
Spraying Systems before it is shipped. After testing, the unit is partially
disassembled for shipment. When you have unloaded the sprayer,
several parts must be reassembled before operation.
Air Cleaner Assembly
Cut away all tape, strapping material and transportation coverings on
all hoses, cylinders and wire assemblies. Dismantle all wood packing
material from the spray bars.
Reinstall the Air Cleaner assembly on the front of the 350VA32 sprayer.
Air Cleaner mounted on front of sprayer
using 3 bolts.Replace the Air Filter yearly.
It consists of a 5” aluminum nipple in a rubber elbow, black plastic air
lter body with element, and pre-cleaner. Three ⁄” bolts with wash-
ers and nuts are included as well as two hose clamps. Mount the air
cleaner assembly on the mounting ange weldment using the three
bolts. Slide the hose clamps over the 5” ID hose. Place them in oppo-
site directions. Insert the 5” aluminum nipple into the 5” ID hose and
tighten the hose clamps.
Spray Bars Assembly
In some instances, the 350VA32 sprayer will be shipped with the spray
bars detached. They will be marked “L” or “R” indicating a left or right
wing assembly. In this manual, all references to left and right are with
the viewer standing at the rear of the sprayer looking forward over the
sprayer, as it would be mounted on the tractor. Left and right wings are
virtually identical, but an inspection of the wiring harness connections
that are dierent on the left and right wings can identify them.
Mount the spray bar assembly on the rear frame of the sprayer. Refer to
Drawing 17021 at the back of this manual.

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Installing the Driveline
Mount the sprayer on the tractor and cut the driveline to t. Follow the
directions from the Bondioli and Pavesi Manual, paying particular at-
tention to the length guideline on page 6.
Your Bondioli and Pavesi manual is
fastened to the sprayer’s drive- line.
One end of the driveline shield tube is marked with a tractor symbol to
indicate the end that attaches to the tractor PTO.
Installing the Control Box
The control box mounts in the tractor cab at any location within easy
reach of the operator. Some common positions are overhead or to the
right.
Attach the red wire directly to the tractor battery 12-volt terminal
post and the green wire directly to the tractor ground post. Failure to
ground the system properly can cause premature failure of the power
supplies. Make sure that you are not operating on a 24-volt tractor
system. Contact the ESS service representative for instructions in this
case. Attach the electrical cable to the front of the 350VA32 sprayer as
shown in the photograph at right.
