CALIBRATION
The SPYDSS-9G is equipped with a Hypro DeflecTip wide-angle flat flood nozzle. The table below will serve as a ref-
erence for application rates. A working pressure of 15-20 psi will provide adequate coverage. The nozzle should be
adjusted to provide a 60-65 inch spray width with a 4-6 inch overlap of the previous spray pass.

Confirming Application Rate
Because walking speeds vary, it is always best to perform a field test to confirm the application rate. The
procedure is simple:
1. Measure an area at least 10,000 square feet.
2. Fill the tank with water.
3. Spray the measured area at 20 psi and at a
comfortable sustainable walking speed.
4. Refill the tank from a calibrated container keeping
track of the amount needed to refill the tank.
5. Divide the number of gallons used by the square footage
of the area sprayed
(Expressed in 1000 square foot
increments).
6. Since the tank holds 9 gallons, divide 9 by the result to obtain
the expected coverage per tank full.
Example:
4.5 gallons used
10,000 square feet sprayed
9 gallons /
0.45
=
20
The capacity is 9 gallons, so in this
example a full tank should cover
20,000 square feet.
4.5 gallons / 10
=
0.45
gallons / 1,000 square ft.
