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.

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Operating Instructions
ESS recommends that the sprayer be operated with only water
the rst time after initial installation. This will allow the operator
to get comfortable with all controls and operation of the sprayer.
Fill the main liquid tank with water.
Operating the sprayer without water in the tank will cause
damage to the centrifugal pump seals! This type of damage
is not covered by your warranty.
Setting the Air Pressure
With the tractor just above idle speed, engage the PTO and increase
the tractor speed until the air pressure reading is around 15 PSI. The
blower is equipped with a pop o valve that protects the blower from
overpressure. The noise created by the pop o valve will alert the
operator to slow the tractor PTO speed until the pop o shuts. At this
point, the blower will be operating at its maximum potential for cor-
rect spraying.
It is normal for a small amount of air to leak from the pop-o valve
during routine operation.
Setting the Liquid Pressure
Turn on the main power switch (1) and verify that the hour meter is
working. Now, turn on the Left and Right Spray switches (2). Both spray
bars will begin to spray.
On the front panel of the sprayer is a gate valve next to the liquid pres-
sure gauge. Opening this valve will decrease pressure and closing the
valve will increase pressure. This valve restricts the return ow of liquid
to the tank. There is a hole in the valve so that when it is fully closed,
some liquid always returns to the tank to maintain tank agitation. Also,
this keeps the gauge from failing in an overpressure situation. Liquid
pressure will be set at the factory between 20 & 30 PSI in order to
achieve a nominal 180-ml/minute ow ±10% out of each nozzle.

8
ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Turning On Charging
After checking that all nozzles are spraying properly, turn on the
Electrostatic Charging System (toggle switch 3, labeled CHARGE).
One of the four LED lamps in the center of the Control Box will glow for
each power supply operating on the sprayer.
Using the meter supplied by ESS, check the charge level of all nozzles.
Follow the procedure in the maintenance section to correctly set the
meter for measuring current. Readings will vary from 9 to 18 depend-
ing upon various conditions. Any reading of 0.00 indicates a nozzle
that is not receiving voltage. Any low readings from 2 to 6 indicate
that the nozzle has some ash present and needs to be cleaned. If all
the nozzles read low, the sprayer is not grounded properly. Please see
the maintenance section for troubleshooting guidelines.
Shutting Down the Sprayer
It is important to shut the sprayer down correctly so that the liquid
lines will be purged of chemical.
Use the graduated cylinder found in the parts kit to check all nozzle
ows before spraying. Any ash or small piece of material that has bro-
ken loose after ESS’ own testing or in transportation can be cleaned at
this time following the procedure outlined in the maintenance section.
Average the readings over the entire sprayer to determine the nozzle
ow rate to use when applying chemicals.
Turn o the Electrostatic Charging System rst (1). Then turn o the
liquid ow to the nozzles, left and right (2). Wait a few seconds until
the nozzles quit spraying.The nozzles will“spit” intermittently as the air
ow purges the liquid supply lines in the spray bars. After the nozzles
have stopped spitting, turn o the main power switch (3).

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Calibration and Field Operation
The model 350VA32 is a low volume sprayer. Tank mixes must be ad-
justed accordingly. The average nozzle ow rate can be adjusted and
operated from 100 to 200 ml/min. Outside this range, nozzle charging
is poor and spray deposition is low. Optimum performance is achieved
by setting the liquid ow in the nozzles around 180 ml/min. Adjust the
liquid pressure using the Liquid Pressure valve. Adjust the spray bars
so that the nozzles are about 18 inches from the crop. At this distance,
the nozzle air will push the charged spray into the plant canopy and
provide adequate overlap of the spray cloud from each nozzle. If the
boom is too close to the crop, then the spray will be moving too fast
to have enough time to be attracted to the top leaf surfaces. This is
known as striping. If the spray bars are too far away, then spray may
not reach into the canopies or spray drift will occur. In windy condi-
tions, the nozzles can be angled forward and the spray bars moved
closer to the crop. Take care to observe that there is no overlapping of
the spray before it enters the plant canopy and adjust accordingly.
When mixing chemicals for a low volume sprayer, it is good practice to
conduct a jar test to determine if the chemicals to be mixed are com-
patible. If they are not, then investigate alternative chemicals or use a
compatibility agent to maintain the chemicals in suspension. It is also a
good idea to treat the water with a pH agent.
ESS does not recommend the use of wetting agents or
spreader-stickers.
How to conduct a jar test
Needed:
Solutions of chemicals in
approximate dilutions
Jar with lid
Gloves and Safety
Glasses
After mixing solutions of
the desired chemicals, place
them in a large jar, cap it se-
curely, and shake vigorously.
Carefully observe the interac-
tion between the chemical
compounds. If the water
becomes milky or cloudy, the
combined solution may plug
the nozzles. Let the jar sit for
one to two hours. If there is
precipitate on the bottom
of the jar, then seek another
combination of chemicals.

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Cleaning and Maintenance
It is very important to follow all the maintenance and cleaning proce-
dures to ensure that the electrostatic sprayer will function properly.
Although the MaxCharge™ nozzle will outperform all electrostatic
spray technology on the market, regular cleaning will ensure peak
operating performance. The sprayer can be washed down with a pres-
sure washer prior to any individual component being cleaned. As a
precaution, apply Sil-Glyde electrical grease to all connections that will
be exposed to pressure washing. This will prevent water damage to the
electrical connections.
Apply enough Sil-Glyde to coat the
metal pin and socket connections of the
nozzles.
Also use Sil-Glyde to protect the low-
voltage connectors.
Cleaning Nozzles
Disassemble the nozzle by unthreading the elec-
trode cover. Pull the hood o. The nozzle consists
of four main components:
1. Nozzle Body
2. Electrode Cover
3. Hood
4. Insulating Ring
The nozzles are mounted under the air tube using
two brass nipples and two swivel connectors. This
allows the operator to aim the nozzles in directions
that are appropriate for travel speeds and wind
conditions. The wiring harnesses and liquid lines
are mounted inside PVC protective covering that
protects parts from chemical and physical damage.
The diagram (right) identies the nozzle compo-
nents and the air, liquid, and electrical connections.
Simple cleaning of the nozzle interior and exterior
with soap and water after each day of use is the
most important thing you can do to ensure trouble
free operation. Cleaning each day avoids long-term
chemical buildup that eventually causes clogs,
poor spray patterns and shortens nozzle life. After
each day’s use, remove the electrode cover and
clean any debris from around the nozzle tip. Clean
the ceramic outlet and all interior and exterior
surfaces. It is important to clean inside the hood
and the two cavities. Wipe clean the exterior of
the wires and all hoses and ttings connected to
the nozzle. Put Sil-Glyde silicon grease inside the
nozzle electrical connections whenever you have
disconnected the nozzle.
After cleaning, make sure the internal and external o-rings are still in
place. Put the insulating ring back on the nozzle and screw the elec-
trode cover back. Replace the hood, pushing it up against the external
o-ring.
The electrode cover should be hand tight. Never use pliers or
other tools to tighten it. The insulating ring should be loose.

12
ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Flushing the Sprayer
After spraying and after properly disposing of any remaining spray
solution, ush the 350/450RC sprayer with a mixture of water and a
cleaning agent. ESS recommends the use of NUTRA-SOL cleaner
which can be purchased from ESS.
Nutra-Sol cleaner is an excellent neutralizer of chemical deposits in
your tank and liquid lines. The use of this product will keep your equip-
ment operating at peak performance. The recommended mixing ratio
is 4 ounces in 12.5 gallons of water (113 grams in 47 liters of water).
Mix the cleaner with water in the 10-gallon (37.9 liter) stainless steel
rinse tank.
To ush the sprayer, rst make sure the main tank has at least 5 gallons
of water and that the rinse tank has been lled with either clean water
or a Nutra-Sol solution. The brass rinse valve that controls the ow from
the rinse tank is on the left side of the sprayer. Rotate the rinse handle
down and open all ball valves. Operate the sprayer and run the entire
contents of the rinse tank through the liquid system to thoroughly
ush all lines.
Do not perform this procedure without at least 5 gallons of water
in the main tank. The centrifugal pump is operating during this
procedure and damage to the seal will occur if the pump is oper-
ated dry for even a short time.
Disassemble the main bowl lter and clean the screen. If heavy wetta-
ble powders have been sprayed, disassemble the ow disk assemblies
and clean the enclosed screens.
Please note: the 350RC does not have a
separate rinse tank.Instead, fill the main
tank with either clean water or a Nutra-
Sol solution.
Location of Dump valve lever.?
Cleaning the Main Tank
The main sprayer tank can be cleaned by rinsing it
with clean water. Empty the rinse water through the
dump valve on the right side of the sprayer.

The above drawing shows an exploded view of the disassembled ow
disk assembly. Please take note of the correct order. The assembly is on
the outlet side of the ball valve that controls the ow of liquid to the
nozzles. You’ll nd them in between the spray bars and protected by
the spray bar mounting frome.
Be careful not to lose the ow disks or mix them up from one assembly

Repairing Power Supply Wires
Option 1: Using Blazing Wire Connectors
The red or black power supply wiring will occasionally break during
normal field operation.The wiring can be repaired easily in the field.
ESS recommends using Blazing Wire Connectors™; several are pro-
vided in your Spare Parts Kit. These connectors are waterproof and
vibration-proof. Although you will need a pocketknife or wire stripper,
no other tools are necessary to repair a broken wire.
Here are the instructions from www.blazingproducts.com/products/con-
nectors/LV9/instructions.html.

ESS 350VA32 ORCHARD SPRAYER OWNER’S MANUAL
Use a heat gun or small butane torch to shrink the shrink tubing. Apply
heat evenly, starting at the middle of the tube and working outward.
Just before you finish shrinking the tubing, apply glue inside it to seal
your repaired connection from moisture.
Caution! Always be careful with heated tools like heat guns.
Remembering to use the thick-walled heat shrink tubing, slip the tub-
ing over the open end of the wire and position it so that the bare wire
is in the middle of the heat shrink tubing.
Now, work with the left wire end.Twist it toward you. By reversing the
twisting direction, you will make a stronger connection and the wire
ends will be less likely to pull apart. Again, twist as tightly as you can.
If you have soldering equipment available, solder the wires together.
Caution! Always be careful with heated tools like soldering irons.
Option 2: Soldering
If you do not have one of the yellow Blazing Connectors, you will need
to repair the broken wiring harness with more traditional methods.
Please note: It is important to use the heavy-walled heat shrink tubing
(Part # 6601) for repairs. Do not use the thin-walled heat-shrink tubing
or electrical tape.These thinner insulating materials will break down
under the harsh duty conditions your sprayer operates in. An imperfect
repair will cause electrical current to“leak” and lower the performance
of the nozzle-charging system.
First, strip back the ends of the broken wires by cutting the red outer
casing, then carefully cut the inner casing to expose the wire itself.
Cross the wire ends in an“X” shape. Now, twist the right end away from
you. Make sure you have good contact between the bare wires.Twist as
tightly as you can.
