ESS TRG OWNER’S MANUAL
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 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!
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 elec-
trostatic 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 low-
voltage 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.

Features of the TRG-5 Sprayer
MaxCharge™ Spray gun

construction and powder-coated nish
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 dierent 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 electrostati-
cally charged and sprayed from
the nozzle. Due to the electro-
static 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.

ESS TRG OWNER’S MANUAL
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.

ESS TRG OWNER’S MANUAL
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.)
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.
To set the incoming air
pressure:
Turn on the air from the ex-
ternal 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 pres-
sure. Set the pressure accord-
ing to the formulas described
at left. Push the black plastic
cover in to lock the new setting.

To set the tank pressure:
Turn on the air from the
pressurized air source. Set the
incoming air pressure accord-
ing to the instructions on the
previous page.
Locate the tank pressure gauge
(liquid-lled gauge marked
1 –30 PSI). Pull the adjustment
knob’s black plastic cover to
unlock it. Turn left (counter-
clockwise) to decrease pres-
sure; turn right (clockwise)
to increase pressure. Set the
pressure between 12 to 15 PSI.
Push the black plastic cover in
to lock the new setting.
Supply air line drier
ESS recommends that growers install dryers in their air lines to mini-
mize the amount of water condensation that is sprayed through the air
line of the TRG-5. Air compressors produce warm, moist air which con-
densates 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 oset 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.
5. Disconnect spray gun quick connect sockets from the
frame quick connect plugs; connect spray gun quick
connect sockets to handgun plugs.
6. Turn on air at external supply.
7. Set unit air pressure as described on the previous page.
8. Set tank pressure regulator to 12-15 PSI.
9. Aim spray gun at spray target and engage trigger;
lock trigger if desired. Note: It takes about 2 minutes for
liquid to spray regularly without air bubbles.
10. Apply spray.
After spraying:
1. Disengage trigger when spray application is complete.
2. Turn ball valve o.

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 ac-
cumulates 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.
Hose reel and liquid inlet filter
Liquid inlet lter
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 inte-
rior 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).
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 airow
to the spray gun. Airow is stopped when the lever is perpendicular to
the hose. Airow is open when lever is parallel to the hose

ESS TRG OWNER’S MANUAL
Stainless-steel tank
The TRG-5 has a 5-gallon (18.9 liter) stainless steel tank. When the com-
pressor 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.
ESS recommends the use of
NUTRA-SOL cleaner which
can be purchased from ESS.
Order S/N#1566.
To open the tank:
1. Slowly open the Pressure release valve by turning it
counter-clockwise (left). This depressurizes the tank.
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 TRG OWNER’S MANUAL
Incoming air pressure regulator
The air pressure regulator controls the amount of pressure sent to the
spray gun. Refer to page 6 instructions to determine the correct air
pressure settings.
Turn the external air source. on 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.
Push the black plastic cover in to lock the new setting.
Note: For best results, set the pressure from a lower pressure to a high-
er pressure. If the pressure is set too high, adjust the regulator below
the desired pressure then adjust it up to the desired pressure.
To verify that the air pressure regulator functions properly:
1. Connect the air inlet hose to the air source.
2. Make sure that the air pressure regulator is set above 0 PSI
If the air pressure regulator is functioning, the gauge will register
above 0 PSI. If the gauge does not register above 0 PSI, contact ESS for
service.
