ESS XT-3 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 applicaon with water. Put a
gallon of clean water in the ESS XT-3 tank and thoroughly spray a known area. Aer
spraying the known area, determine how much water was used from the amount le
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 2)
Next determine the dosage. This is the amount of chemical you wish to dispense in a
given area. Appropriate dosage depends upon chemical label recommendaons,
disinfecon or sanizaon goals, level of pest or disease infestaon, past
experience with parcular chemicals, and other variables.
Because electrostac spraying is a much more eecve spraying method, ESS
recommends that you experiment to nd the opmum chemical concentraon. Start
spraying using the same chemical rate used in the past with other sprayers. Test to
ensure that infecve agent levels have been reduced to desired levels. At the next
applicaon, 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, tesng aer each experiment to see if the desired results are
being accomplished. If you are planning to cut rates then it is very important to
conduct these experiments to determine the opmum chemical concentraon.
A note about operang temperatures
The MaxCharge nozzle should always be operated at temperatures above 10°
Celsius (50° Fahrenheit). When the ambient temperature is colder than this, the
evaporave 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
How to conduct a jar test
Needed:
Soluons of chemicals in
approximate diluons
Jar with lid
Gloves and Safety
Glasses
Aer mixing soluons of the desired
chemicals, place them in a large jar,
cap it securely, and shake vigorously.
Carefully observe the interacon
between the chemical compounds. If
the water becomes milky or cloudy,
the combined soluon may plug the
nozzles. Let the jar sit for one to two
hours. If there is precipitate on the
boom of the jar, then seek another
