Overview of the ESS TRG-5
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 TRG-5 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 thousands 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 MaxCharge™ 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 result 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 interior 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 conventional spraying is dramatic.
Where Does the Spray Go?
The University of California completed a series of tests to investigate 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 benet!
Electrostatically charged droplets are
attracted to plant surfaces.
A picture worth a thousand words…
In this test, uorescent dye has been
sprayed on two round knobs. The left
knob was sprayed with the electrostatic
system ON; the right knob was sprayed
with the same sprayer, but with the electrostatic system OFF. Note how even the
coverage is on the electrostatic knob.

About the low-voltage system of the MaxCharge™ spray gun
For operator safety, the MaxCharge spray gun is powered by a lowvoltage power supply. The rechargeable 9-volt batteries are in the
handle of the TRG-5 spray gun. The electrostatic charge imparted to
the spray is not strong enough to harm people. Some people report
feeling a “tingle” or a slight stinging sensation when the spray from the
nozzle falls on their bare skin.

About your TRG-5 sprayer
The TRG-5 is a sprayer that
depends on an external source
of pressurized air. The air
passes from the air inlet hose
through a lter and follows
two dierent routes from a
brass tee. One route goes to
the hose reel and through the
red air hose of the twinline
hose. The other route goes to
the tank pressure regulator
and then to the tank. When
external air supply is running
and tank pressure regulator
is set at 12-15 psi, the tank is
pressurized and continuously
agitated to prevent separation
and settling of the chemical(s).
From the tank, the pressurized
liquid line goes to the hose reel
and through the grey hose of
the twinline hose. The twinline
hose carries both pressurized
liquid and air to connect to the
spray gun. The liquid combines
with the pressurized air and
atomizes the chemical mix
into 40 micron VMD (Volume
Median Diameter) drops. The
droplets are then electrostatically charged and sprayed from
the nozzle. Due to the electrostatic charge, the droplets are
attracted to all plant surfaces in
the direction that the handgun
points, including the back of
leaves and foliage deep within
the canopy.

Operating instructions
ALL OPERATORS must read this Owner’s Manual completely
and thoroughly before operating the TRG-5 sprayer. They
must be familiar with all operating instructions and safety
precautions.
Unpacking the sprayer
In the shipping box there should be:
one TRG-5 sprayer
one spray gun in a box,
one TRG-5 Parts Kit
Your new TRG-5 Sprayer is fully assembled. The sprayer is fastened to
the shipping crate with one 3-inch wood screw located on the tank
platform of the TRG-5 sprayer. Remove the screw with a Phillips head
screwdriver.
Carefully open the spray gun box, remove the spray gun, and unwrap
the bubble wrap from the spray gun. Store the box and bubble wrap
for future shipping. You will need this box to return the spray gun for
its Yearly Service.
The Parts Kit contains a collection of small parts commonly needed to
maintain and repair your TRG-5 sprayer as well as the battery charger
for the spray gun, a spray gun shoulder pad, and the TRG-5 Owner’s
Manual. Please store your Parts Kit in a safe place for future use.
Among the items in the Parts Kit you will nd one extra ow disk and
one extra strainer. We call your attention to these parts because they
are indeed very small and easy to overlook; however they are essential
for your sprayer to run correctly. (See the section about the air lter
for detailed instructions on cleaning and replacing the air lter. See
the section on the liquid lter to clean or replace the ow disk and the
strainer.)
A warranty registration card is bound into the manual after the
Warranty page. After unpacking the sprayer, please take time to ll this
card out and send it in to ESS. This will insure your warranty protection
in the event anything happens to your sprayer or handgun.
Before use
Connect the battery charger to the spray gun. Charge the battery for
6 to 8 hours before using the TRG-5 sprayer. After charging your spray
gun, store the battery charger in a secure location.

Setting the air pressure for the
incoming air flow
1. Start with an initial pressure setting of 60 PSI.
2. Count the number of nozzles on your spray gun. Add 5 PSI
for each nozzle over 1. For example:
- for a single nozzle add 0 to the initial setting
- add 5 PSI for a two nozzle spray gun
- add 10 PSI for a three nozzle spray gun
3. Determine the length of air hose furnished with your
sprayer. Add 10 PSI to the initial pressure setting for each
100 feet of air hose length. This is the desired air pressure
setting for the external air source.
Example:
Your TRG has the optional two-nozzle gun with 100 feet of air hose on
the reel.
60 PSI + 5 PSI + 10 PSI = 75 PSI
Example:
Your TRG has a single-headed nozzle and has 250 feet of hose.
60 PSI + 0 PSI + 25 PSI = 85 PSI
Note: The spray gun air ow requirement is 6 to 10 CFM of air ow
per nozzle.
The air pressure required at the nozzle is 55 to 75 PSIG.
(It’s greater because the design of the MaxCharge nozzle
increases the air pressure and air velocity.)
To set the incoming air
pressure:
Turn on the air from the external air source. Locate the
air inlet regulator (liquid-lled
gauge with a range of 0 to 100
PSI). Pull the adjustment knob’s
black plastic cover to unlock it.
Turn left (counter-clockwise) to
decrease pressure; turn right
(clockwise) to increase pressure. Set the pressure according to the formulas described
at left. Push the black plastic
cover in to lock the new setting.
Air ow at the upper end of the range will require higher air
pressure from the source and will yield a longer spray plume
and ner liquid droplet size.
The charge level at the nozzle will increase or decrease as the
air ow changes due to the liquid/air ratio varying. By
regulating the air pressure and checking the charge level the
nozzle liquid charge level can be optimized.

Supply air line drier
ESS recommends that growers install dryers in their air lines to minimize the amount of water condensation that is sprayed through the air
line of the TRG-5. Air compressors produce warm, moist air which condensates in air delivery lines during pumping. If allowed to travel into
a sprayer, this moisture can corrode or freeze its air lines or regulators.
A simple air dryer installed in the hose air lines can prolong the life of
spraying equipment. Typically, an air dryer is a separator or drain with
a plug or valve that is oset from the line to trap water build-up before
it leaves the air line through connectors. Air lines should be drained
monthly if they are used frequently.
Steps for operation
1. Connect external air supply to the air inlet hose
2. Disconnect tank quick connects and open tank.
3. Prepare tank mix.
4. Close tank and reconnect all quick connects.

Hose reel and liquid inlet filter
The hose reel contains the twin line hose running from the main unit
to the handgun. Air (red hose) and liquid (gray hose) are plumbed into
the hose reel from the compressor and liquid tank. There is a lter
attached to the liquid inlet on the hose reel. The lter consists of a
strainer (pictured below), O-ring (installed on cap) , and bowl-shaped
cap. Periodically check and clean this lter to clear any debris that accumulates there. Replace the O-ring when it become worn.
The cap turns counter-clockwise (to the left) to open and clockwise (to
the right) to close.
How to tell the cap end of the strainer
It’s important to replace the strainer in the correct direction. Carefully
examine the ends of the strainer. If you can see the terminus of the interior plastic ribs, that’s the “open” end. If there is a smooth plastic ring, that
is the “closed” end. Place the closed end into the lter cap (Remember:
CLOSED to CAP).
Liquid inlet lter
The ball valve (airflow On/Off)
The ball valve is a manually operated valve located at the end of the
red hose on the twin line hose. The ball valve allows or restricts airow
to the spray gun. Airow is stopped when the lever is perpendicular to
the hose. Airow is open when lever is parallel to the hose

Stainless-steel tank
The TRG-5 has a 5-gallon (18.9 liter) stainless steel tank. When the compressor is operating and the tank pressure gauge is set between 12-15
PSI, the liquid in the tank is continuously agitated. This helps prevent
separation and settling of the chemical mixture.
There is a pressure release valve lever on the tank lid that allows the
operator to release pressure in the tank before opening. When the
lever is horizontal, the tank is pressurized; when the lever is vertical,
the tank is not pressurized and can be safely opened. When the TRG-5
is running, you will hear a small amount of air escaping from the tank
lid even when the lid is fastened and latched. This is due to agitation
and is normal.
Pressure release valve
Pressure release valve
Latched and pressurized Open (after being depressurized)
To open the tank:
1. Slowly open the Pressure release valve by turning it
counter-clockwise (left). This depressurizes the tank.
CAUTION:
TANK CONTENTS UNDER PRESSURE
Stand back when opening the
Pressure release valve.
Note: Do not operate
the sprayer when the
tank lid is not securely
closed. Chemicals may
splash out onto the
operator if the tank is
open during operation
2. Pull the tank lid’s latch up.
3. Holding on to the latch, rotate the tank lid 90° clockwise.
4. Pull out the tank lid. Notice the direction of the tank lid in
relationship to the tank opening.
To close the tank:
1. Slide the lid into the tank opening, using the same direction
as when it was removed.
2. Rotate the lid 90° counterclockwise.
3. While pulling the lid up to seal it against the tank opening,
push down on the lid latch until it is parallel with the
tank lid and seals tightly.
4. Close the Pressure release valve by turning it clockwise.
Note: Do not operate the sprayer when the tank lid is not securely
closed. Tank agitation is powerful and liquid may splash out if the lid is
not sealed.
The tank should be thoroughly cleaned immediately after each use
by triple-rinsing the tank; a commercially available tank cleaner like
Nutra-Sol may be used and is recommended when the TRG-5 is used to
spray wettable powders on a regular basis.
ESS recommends the use of
NUTRA-SOL cleaner which
can be purchased from ESS.

Spray gun connections
The air connection
The quick connect for the air connection is at the end of the red line
of the twinline hose. The other end of the air line hose connects to the
air leader of the spray gun. The air leader of the spray gun is below the
liquid leader and is easily recognizable because its connector is larger
than the liquid connector – it is not possible to connect the air hose to
the liquid leader. The air line hose is red.
The liquid connection
The quick connect for the air connection is at the end of the gray line
of the twinline hose and connects to the liquid leader of the spray gun.
The liquid line has a smaller diameter than the air line. Its ttings are
a dierent size than the air lines’ and it’s not possible to cross-connect
them.
How to store the hose quick-connects
when not in use
The quick-connect sockets and plugs used on your TRG-5 sprayer are
precision components and should be kept clean. When not attached
to the spray gun leaders, the socket ends of the twin-line hose should
be attached to the plugs provided on the TRG-5 frame. This will ensure
that the quick-connect plugs are not damaged while the TRG-5 is being moved.
Don’t worry about connecting the air
or liquid to the wrong hose – the liquid
plug/socket is smaller than the air plug/
socket. It’s not possible to cross-connect
them.

Nozzle assembly
It is very important to follow all the maintenance
and cleaning procedures 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 nozzle assembly is located at the end of the
spray gun wand. It is composed of a nozzle body,
internal o-ring, Teon ring, cover, external o-ring,
and a hood (see labeled drawing at right). To access
the nozzle components, just unscrew the nozzle
cover by hand.
Cleaning the spray gun
Always rinse the spray gun out with clean soapy
water after every day’s spraying. That is the most
important thing you can do to ensure trouble free
operation of your TRG-5 sprayer. By cleaning after
each and every working day you will avoid the longterm chemical buildup that eventually causes clogs,
poor spray patterns and shortens nozzle life.
Establish maintenance intervals to disassemble and
clean the nozzle. Your nozzle maintenance schedule
will vary depending on the types of chemicals used
and adherence to pre- and post-spray checks. In
general it is sucient to thoroughly clean nozzles
every 50 hours. If heavy loads of wettable powers
are used, the cleaning schedule should be sooner.
To clean the nozzle assembly
1. Slide the hood over the nozzle cover.
2. Unscrew the cover from the nozzle base and remove the Teon ring. Clean any debris from
around the nozzle tip.
Note: There is a small o-ring in the nozzle around the base of the tip, take care that it doesn’t fall
o. If it does, clean it and press back into place. Also, take care not to damage the nozzle tip when
the cover is removed.
3. Soak the ring, cover, and hood in a mild detergent solution. Use a small brush (soft or mild
bristle) to clean the inside of the cover and the hole through it. Also, be sure to clean the hood.
It is important to clean inside the hood and the two cavities. Rinse thoroughly.
4. Scrub the nozzle base with the detergent solution using a soft bristle brush. Clean the ceramic
outlet. Be sure to thoroughly clean the base cavity and take care not to damage the nozzle tip.
Rinse and make sure the small o-ring is in place.
5. Reassemble nozzle by placing the Teon ring on the base and screwing the cover on hand
tight. Next, slide the hood over the nozzle and seat it securely against the external o-ring.
Wipe clean the exterior of all hoses and ttings connected to the nozzle.
The electrode cover should be hand tight. Never use pliers or other tools to tighten it. The insulating
ring should be loose.
ESS TRG OWNER’S MANUAL

You may wish to purchase Nutra-Sol Tank Cleaner from ESS (S/N#
1566), which cuts hard water scale and chemical deposits from the
electrode and internal component of the spray gun. The regular use of
Nutra-Sol will keep your equipment operating at peak performance.
The recommended mixing ratio is 4 ounces in 12.5 gallons of water
(113 grams in 47 liters of water).
Pre-spray check
I. Inspect Nozzles
Check nozzle cover to make sure it is on hand tight (do not
over tighten or use a wrench). Make sure the hood is seated
rmly to the nozzle base and against the external o-ring.
II. Preparing the Tank Mix
If you will be spraying wettable powders it is a good idea to
use a compatibility agent with the water and tank mix.
Compatibility agents are chemicals mixed with the water
that make mixing easier and keep heavy concentrations
uniformly in suspension. Some brand name additives are
COMPLIMENT™, UNITE®, and BALANCE™. Check with your
local chemical supplier for others that are available.
Post-spray check
ESS recommends the use of
NUTRA-SOL cleaner which
can be purchased from ESS.
Order S/N#1566.
After each spray it is essential that hoses and spray gun be
ushed with clean soapy water. This will help prevent
chemical build-up that can clog lines and nozzles. Also, it is
recommended that the nozzle exterior (black portion of
nozzle) and nozzle hoods be cleaned with soapy water at this
time.
ESS TRG OWNER’S MANUAL

Batteries
The nozzle charging operates on two 9-volt rechargeable batteries
which are located in the base of the spray gun. In average conditions,
the batteries will last 10 to15 hours of operation on a charge. They
should be recharged when the charging indicator on top of the spray
gun shell doesn’t glow when air is going through the spray gun.
After approximately 800 to 1000 hours of service the battery pack will
no longer be able to hold an adequate charge and will need to be replaced. Replace with nickel-hydride rechargeable batteries. Order the
TRG’s replacement battery pack from ESS.
9v
Remember to charge the
spray gun batteries after
every work session!
To change the batteries:
1. Unscrew the two 6-32 x ½” Phillips head machine screws
which hold the battery cover in place.
2. While holding the leads in one hand, gently disconnect the
batteries from the leads. Be careful not to tear the leads o
the wires or to tear the lead wires out of the power supply.
3. Connect the fresh battery pack to the leads.
4. Replace the battery cover. Screw the two 6-32 x ½” Phillips
head machine screws back in to secure the battery cover.
5. Charge the spray gun before attempting to use it.

Spraying with your ESS sprayer
Note: When using unfamiliar equipment or chemicals, always test on a
small area before treating the entire crop or surface. Do not use a chemical
with the ESS sprayer if the label prohibits use in low-volume sprayers.
Spray Technique
As in spray painting, the goal is to achieve even coverage over the
surface. The ESS MaxCharge spray gun is designed to help you do just
that by propelling the chemical spray with a gentle air ow, you can
stay well away from the target surface and let the electrostatic attraction do the rest of the work.
Please note: the spray droplets are very, very ne --- about 40 microns
each. If you are used to working with a conventional sprayer, you may
make the mistake of thinking the target is not wet enough because
you do not see large beads of liquid. In fact, after a pass with the
TRG’s MaxCharge spray gun, the surface of the target should just barely glisten with moisture. The ne droplets will evaporate quickly.
Here are some tips to achieve the best possible coverage with the ESS
TRG-5 sprayer.
1. Before each job, ensure that your sprayer is in good
working order (see the pre-spray checklist on page 8 of
this manual).
Let the MaxCharge™ Spray
gun do the work!
There’s no need to stick the tip
of the spray gun into the plant
canopy. The electrostatically
charged spray will blow into
the plant canopy and the droplets will even change direction
to nd a dry surface to cling to.
2. The optimal spraying distance is at least 18 inches away
from the target surface, however 36 to 48 inches may
provide a more even coating. This gives the ne mist
produced by the MaxCharge nozzle room to develop into a
chaotic cloud that will be attracted to the target surface.
3. Hold the spray gun at right angles to the target surface.
Starting at the highest point and using zig-zag horizontal
strokes about 1 meter (3 ft.) wide, spray down to the
lowest point. Try to have each stroke overlap the previous
stroke by about 50%.
4. You can use vertical strokes if it suits the area better. Just
make sure to work in a methodical pattern and let your
strokes overlap.
5. When moving to the next section, allow it to overlap the
previous section by a few inches. Do not leave a gap.
6. The target surface should just barely glisten with the spray.
Do not over-saturate the surface; if you see runs or puddles
it means you are wasting chemicals. Do check to make sure
the newly-sprayed surface is very slightly damp.
7. Be careful to keep the spray gun barrel as level as possible.
If you allow the nozzle to point down too much, it may drip
occasionally.
8. Unlike spray painting, you don’t have to stop the spray on
every return stroke. Just engage the trigger lock and
concentrate on the regular pattern of spraying.
9. Periodically check to make sure the red light is illuminated
on the spray gun.
ESS TRG OWNER’S MANUAL

Preparing a tank mix
The tank mix depends on two factors: water requirement and dosage.
Water requirement is the amount of water needed to cover the given
treatment area. Dosage is the amount of chemical which should be
applied in a given treatment area.
First determine the water requirement for your sprayer over a known
area. An easy way to determine water requirement is to spray a trial
application with water. Put a gallon of clean water in the ESS SC-1 tank
and thoroughly spray a known area. After spraying the known area,
determine how much water was used from the amount left in the tank.
This is the water requirement for the given area. Next measure the
known area to determine how many square feet were sprayed. Write
down both values for future reference.
___________ (gallons) Water Requirement
for __________________ (size of known area in ft)
Next determine the dosage. This is the amount of chemical you wish to
dispense in a given area. Appropriate dosage depends upon chemical
label recommendations, disinfection or sanitization goals, level of pest
or disease infestation, past experience with particular chemicals, and
other variables.
Because electrostatic spraying is a much more eective spraying method, ESS recommends that you experiment to nd the optimum chemical concentration. Start spraying using the same chemical rate used in
the past with either hydraulic or air assisted sprayers. For example, if in
the past you have used 2 ounces of chemical in a hydraulic sprayer to
spray a known area; then mix 2 ounces of chemical to the water required by the TRG-5 to spray the same known area. In other words, the
same amount of chemical is sprayed out in the area but with much less
water.
DO NOT
OVERFILL
THE TANK
ESS recommends that the tank not be
lled past the full level mark, since the
force of agitation may cause liquid to
escape through the air bleed hole in the
tank lid.
Example:
You have two greenhouses covering 10,000 square feet that are sprayed using a conventional hydraulic sprayer. In the past you mixed 6 ounces of chemical to 25-50 gallons of water in order to spray both
house at full rate.
10,000
square
feet
With your new ESS sprayer you need to nd out how much water is needed to spray the known area.
The amount of water required to spray both houses is the amount of water in which you mix the
6 ounces of chemical in. Depending on the crop sprayed, you will use approximately 1to 2 gallons of
water with the ESS sprayer to cover 10,000 square feet. This applies to all chemicals, even wettable
powders.
10,000
square
feet
ESS TRG OWNER’S MANUAL
25
After becoming familiar with the sprayer spraying at full rate, you can
start reducing the amount of chemical used for each spray. Keeping
the amount of water in the tank constant, cut the amount of chemical
mixed in by 15 to 25% for each spray until a desirable kill is no longer
achieved. If you are planning to cut rates then it is very important to
scout your crop to determine spray eciency.
Chemical compatibility
It’s sometimes desirable to spray a mixture of two dierent chemicals
at the same time. It is good practice to conduct a jar test to determine
if the chemicals to be mixed are compatible. 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 securely, and shake vigorously.
Carefully observe the interaction 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.
A note about operating temperatures
The MaxCharge nozzle should always be operated at temperatures
above 10° Celsius (50° Fahrenheit). When the ambient temperature is
colder than this, the evaporative cooling caused as the spray is atomized will freeze the nozzle opening.
Nozzle freeze-up can also occur when the liquid to be sprayed is colder
than 10° C (50° F).
IMPORTANT
Water temperature must be at least
10° C (50° F). When the liquid and air
meet in the nozzle, the temperature of
the liquid deceases. As a result, water at
temperatures below 10° C (50° F) may
freeze and clog the nozzle.
