ESS SC-EB OWNER’S MANUAL
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-EB 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 ft2)
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 effective
spraying method, ESS recommends that you experiment to
find the optimum chemical concentration. Start spraying
using the same chemical rate used in the past with other
sprayers. Test to ensure that infective agent levels have
been reduced to desired levels. At the next application,
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,
testing after 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 optimum chemical concentration.
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.
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).
Preparing a Tank Mix
HOW TO CONDUCT A JAR TEST
Needed:
Solutions of chemicals in approximate dilutions
Jar with lid
Gloves
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.
