ESS SC-ET OWNER’S MANUAL
Air-assisted electrostac sprayers produce electrically charged spray drops that are
carried to the target in a low pressure, gentle, air stream. The heart of the SC-ET
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 thousands of ny spray drop-
lets are blown out of the nozzle and move onto the target where they are aracted
to surfaces by electrostac forces. The electrostac charge induced by the
MaxCharge™ nozzle is strong enough to allow the droplets to move in any direc-
on to cover surfaces, even defying gravity to coat the underside of leaves and the
back side of the target objects. The result is uniform spray coverage on hidden
surfaces that other sprayers miss. Air-assisted electrostac sprayers give more
than twice the deposion eciency of hydraulic sprayers and non-
electrostac types of air-assisted sprayers. The grower benets in terms of signi-
cant reducons in applicaon costs and opmized insect and disease control,
sanizaon of beef or other coverage.
The MaxCharge™ nozzle is easy to clean and corrosion-proof. The interior ceramic
outlet resists the wear three mes beer 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
applicaon of chemical.
The comparison of air-assisted electrostac spraying versus convenonal spray-
ing is dramac.
Overview of the ESS Model SC-ET Air Assisted
Electrostac Sprayer
Where does the spray go?
The University of California completed a series of tests to
invesgate what happens to spray liquid aer it leaves the
nozzle.
Conclusion: ESS technology places over 4 mes the amount of
spray onto the plant surface using 1/2 the amount of chemicals.
Furthermore, they also reported that ESS sprayers send 2/3 less
chemicals to the ground and into the air. Less chemical used
overall, less waste, and less dri than convenonal 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 le knob was
sprayed with the electrostac system ON;
the right knob was sprayed with the same
sprayer, but with the electrostac system
OFF. Note how even the coverage is on the
electrostac knob.
Electrostacally charged droplets
are strongly aracted to the
underside of surfaces.

The compressor becomes hot to the touch during normal use. Do not touch the SC-ET compressor aer it has
been running.
Stay clear of the hot compressor when making adjustments inside the SC-ET case or replacing the tank.
The sprayer’s compressor is equipped with a thermal overload switch. If it overheats, the compressor will stop
running. Unplug the sprayer and let it stand for one hour with the door open. The unit should then be able to
restart.
CAUTION: HOT SURFACE
CHEMICAL SAFETY PRECAUTIONS
Read and follow all instrucons on the chemical or pescide manufacturer’s label.
Use protecve clothing, eye protecon, and gloves when mixing chemicals to be sprayed with the SC-ET
sprayer.
Always use a respirator and eye protecon when spraying with the SC-ET.
Follow the chemical’s manufacturer’s recommendaons in handling, mixing, applying, storing and dis-
posing of chemicals.
Be aware of poisoning symptoms and know the appropriate rst aid.
Know the length of me needed to pass before allowing people and pets to go back into the sprayed area.
About the low-voltage system of the MaxCharge™ Spraywand
For operator safety, the power supply for the MaxCharge™ spraywand is enrely separate form the power supply for
the sprayer’s compressor. The spraywand is powered by 9-vold baeries in the handle of the SC-ET sprayer. This
low-voltage charge is not enough to harm people. Some people report feeling a ”ngle” or a slight snging sen-
saon when the spray from the spraywand falls on their bare skin.

ESS SC-ET OWNER’S MANUAL
READ AND FOLLOW THE CHEMICAL
MANUFACTURER’S INSTRUCTIONS CAREFULLY.
It is extremely important for the owner/
operator’s safety as well as the safety of other
people in the vicinity that all chemical safety
precauons are followed.
This label is placed on top of the SC-ET Sprayer
near the quick connect sockets.
The SC-ET compressor becomes hot during normal
operaon.
DO NOT TOUCH
This label is wrapped around the hose to remind
you to clean the lters regularly. The number one
cause of poor sprayer performance is a clogged or
ditry lter.
________________________________________
There will be a small shock when using our
sprayers. To avoid this shock place your thumb
on the bolt at the top of the spraywand.
Safety Decals
Appropriate safety decals are placed on ESS equipment in order to alert the operator to possible dangers.

If you have a pacemaker, we would recommend that you not operate an electrostac sprayer, or if you elect to do
so, know that you are accepng any risk associated therewith. Just to be clear, no one, with a pacemaker, has ever
had a problem using our electrostac sprayers, however, several years ago a physician expressed concern, even
though his opinion was un-tested and not founded in any research. Since that me, we have taken the ulmate safe
approach and recommended that those with pacemakers not operate our electrostac sprayers.

ESS SC-ET OWNER’S MANUAL
Nozzle Assembly_______________________________
It is very important to follow all the maintenance and cleaning
procedures to ensure that the electrostac sprayer will funcon
properly. Although the MaxCharge™ nozzle will outperform all elec-
trostac spray technology on the market, regular cleaning will ensure
peak operang performance.
The nozzle assembly is located at the end of the spraywand wand. It is
composed of a nozzle body, internal o-ring, Teon ring, cover, ex-
ternal o-ring, and a hood (See labeled drawing). To access the nozzle
components, just unscrew the nozzle cover by hand.
Cleaning the Spraywand
Always rinse the spraywand out with clean soapy water aer ever
day’s spraying. That is the most important thing you can do to en-
sure trouble free operaon of your SC-ET sprayer. By cleaning aer
each and every working day you will avoid the long-term chemical
buildup that eventually causes clogs, poor spray paerns 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 gen-
eral it is sucient to thoroughly clean nozzles aer 50 hours. If
heavy loads of weable powders are used, the cleaning schedule
To Clean the Nozzle Assembly
1. Slide the hood over the nozzle cover.
2. Unscrew the cover from the nozzle base and remove the teon ring. Clean any debris from around the nozzle p.
NOTE: There is a small o-ring in the nozzle around the base of the p take cauon that it doesn’t fall o. If it does, clean
it and press back into place. Also, take care not to damage the nozzle p when the cover is removed.
3. Soak the ring, cover and hood in a mild detergent soluon. Use a small brush (so or mild bristle) to clean the in-
side of the cover and the hold through it. Also, be sure to clean the hood. It is important to clean inside the hood
and the two cavies. Rinse thoroughly.
4. Scrub the nozzle base with the detergent soluon using a so bristle brush. Clean the ceramic outlet. Be sure to
thoroughly clean the base cavity and take care not to damage the nozzle p. Rinse and make sure the small o-
ring is in place.
5. Reassemble nozzle by placing the teon ring on the base and screwing the cover on hand ght. Next slide the hood
over the nozzle and seat it securely against the external o-ring. Wipe clean the exterior of all hoses and ngs con-
nected to the nozzle.
The electrode cover should be hand ght. Never use pliers or other tools to ghten it. The insulang ring should be
loose.
NOTE: There will be a drip eect from the nozzle. The drip results from the accumulaon of ny electrostacally charged
droplets wrapping back and coang the spraywand nozzle.

ESS SC-ET OWNER’S MANUAL
It is important to inspect the lter for deterioraon. When handling, if the lter be-
gins to break apart or crumble, replace immediately.
Pre-Spray Check
1. Inspect Nozzles
Check nozzle cover to make sure it is on hand ght (do not overghten or use a
wrench). Make sure the hood is seated rmly to the nozzle base and against the
external o-ring.
2. Preparing the Tank Mix
If you will be spraying weable powders it is a good idea to use a compability
agent with the water and tank mix. Compability agents are chemicals mixed
with the water that make mixing easier and keep heavy concentraons uni-
formly in suspension. Some brand name addives are COMPLIMENT™, UNITE®,
and BALANCE™. Check with your local chemical supplier for others that are avail-
able.
Post-Spray Check
Aer each spray it is essenal that hoses and spraywand be ushed
with clean soapy water. This will help prevent chemical build-up that
can clog lines and nozzles.
The Air & Liquid Delivery System
The air compressor
The air compressor produces compressed air which atomizes and propels the
liquid. It plugs into a 110 or 220 volt electrical source. Use the SC-ET with a
three pronged extension cord of no more than 50 feet and rated for no less
than 15 amp service. The On/O switch is on the back of the case. Check the
fans on the side of the case for debris build up.
Cleaning The Air Filter
To clean the air lter, pull o the lter cap. Inside, remove foam lter,
and wash in warm, soapy water.

3. Release the sleeve.
4. Pull on the socket body to ensure that it is properly seated and
cannot be pulled o the plug when the sleeve is down.
Air connecon
The quick connect for the air connecon is on the outer le side of the SC
-ET case, when the front of the case is facing you. The other end of the twin
line hose connects to the air leader of the spraywand. The air leader of the
spraywand 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 blue.
Liquid connecon
The quick connect for the tank connecon (liquid line) is also on the outer
le side of SC-ET case. It is smaller and is above the air quick connect sock-
et. The other end of the twin line hose connects to the air leader of the
spraywand. The liquid line is blue.
Adaptor
Each adaptor will have a number imprinted on it. This number indicates
the size of the ow disk. The standard ow disk size used at ESS is .30 and
your unit is equipped with a number .30 ow disk. If a higher or lower ow
rate disk is preferred, please contact an ESS employee.
To connect or disconnect the air or
liquid connecons on the spray-
wand, pull back the outer sleeve of
the socket to release

ESS SC-ET OWNER’S MANUAL
Remember to charge the
spraywand baeries aer eve-
ry work session!
Baeries
The nozzle charging system operates on two 9-volt rechargeable baeries which are located in the base of the
spraywand. Please charge the baeries fully before the rst use. In average condions, the baeries will perform 5-
6 hours of operaon on an individual charge. The baeries should be recharged when the charging indicator light
on top of the spraywand shell fails to glow even though air connues to ow through the spraywand. Aer
approximately 800-1000 hours of service, the baeries will no longer be able to hold an adequate charge and will
need to be replaced. Substute with 9-volt nickel-hydride rechargeable baeries, unl the SC-ET’s replacement
rechargeable baery pack from ESS can be ordered.
To change the baeries:
1. Unscrew the two 6-32 x 1/2” Phillips head
machine screws which hold the baery cover in
place.
2. While holding the leads in one hand, gently
disconnect the baeries from the leads. Be
careful not to tear the leads o the wires or
tear the lead wires out of the power supply.
3. Connect the fresh baery pack to the leads.
4. Reconnect the baery cover. Screw the two
6-32 x 1/2” Phillips head machine screws back
in to secure the baery cover.
5. Charge the spraywand before aempng to
use it.
14
Be advised: Non-rechargeable 9-volt baeries can be used, however do not
plug the baery charger into the spraywand while non-rechargeable baeries
are installed. This will result in serious damage to the nozzle’s charging sys-
tem and null the warranty.
We recommend charging depleted
baeries for 4-6 hours.
We do not recommend plugging a
charger into a fully charged spraywand.
This may cause baeries to over heat or
swell.

ESS SC-ET OWNER’S MANUAL
Spraying With Your ESS Sprayer
Note: When using unfamiliar equipment or chemicals, always test on a small area before treang the enre crop
or surface. Do not use a chemical with the ESS sprayer if the label prohibits use in low-volume sprayers. This unit is
for heavy-duty use. During operaon the hose will heat up naturally, therefore, be aware of heat and periodically
allow for breaks if it gets too hot.
Spray Technique
As in spray painng, the goal is to achieve even coverage over the surface. The ESS MaxCharge™ spraywand 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 electrostac aracon 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 con-
venonal 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, aer a pass with the SC-ET MaxCharge™ spraywand, the surface of the target should
just barely glisten with moisture. The ne droplets will evaporate quickly.
Here are some ps to achieve the best possible coverage with the ESS SC-ET sprayer.
Note: If you li the
spraywand above chest
height, it will most likely
start to spuer or even
stop spraying, because of
that fact that the liquid is
siphoning from the tank.
1. Before each job, ensure that your sprayer is in good working order
(see the pre-spray checklist on page 11 of this manual).
2. The opmal spraying distance is at least 24 inches away from the
target surface, however, 30 to 36 inches may provide a more even
coang. This gives the ne mist produced by the by the MaxCharge™
nozzle room to develop into a chaoc cloud that will be aracted to the
target surface.
3. Hold the spraywand at right angles to the target surface. Starng at the
highest point and using zig-zag horizontal strokes about 1 meter (3.)
wide, spray down to the lowest point. Try to have each stroke overlap
the previous stroke by about 50%.
4. You can use vercal stokes if it suits the area beer. Just make sure to
work in a methodical paern and let your strokes overlap.
5. When moving to the next secon, allow it to overlap the previous sec-
on 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
wasng chemicals. Do check to make sure the newly-sprayed surface is
very slightly damp.
7. Be careful to keep the spraywand barrel as level as possible. If you al-
low the nozzle to point down too much, it may drip occasionally.
8. Unlike spray painng, you don’t have to stop the spray on every return
stroke. Just engage the trigger lock and concentrate on the regular
paern of spraying.
9. Periodically check to make sure the red light is illuminated on the spray-
wand.
