15
FAMILIARIZATION
OPERATOR CONTROLS
The below illustration shows the standard operator control pendant and its functions:
1. Power switch when asserted (turned on) applies
power to the control pendant as well as provides
operating voltage to allow fuel flow to the engine.
2. RED LED (Light Emitting Diode) when illuminated
implies the power switch has been turned on and
ready to receive commands.
3. Engine on-off-start switch is a 3 position switch that
controls the status of the sprayer’s engine. When in
the OFF position, a control voltage is sent to the relay
beside the engine. When this relay is energized, the engine’s ignition system is shorted
to Ground. When in the ON position, the engine is ready to run and the ignition is ready.
The START position is a spring loaded momentary switch that engages the engines starter
motor and will continue to engage the starter until the engine is started or the switch is
released.
4. Flush switch when in the ON position sends a control voltage to the 3-way electric
solenoid valve which is connected to both the flush tank and the main formulation tank.
Selecting the flush ON position selects the contents of the flush tank to be pumped
through the insecticide pump when the spray switch is turned on.
5. Yellow LED when illuminated implies the flush tank has been selected.
6. Spray on/off switch turns the insecticide pump on and off when this switch is asserted. If
the sprayer is running (engine on) and the spray switch is asserted, the pump will begin
to run at a calibrated rate. If the engine is not running and the toggle switch on the pump
electronic enclosure is in the down position, the pump will not run when the spray switch
is turned on.
Additionally, the Spray on/off switch when asserted applies a control voltage to the
throttle solenoid (if equipped) increasing engine RPM to a preset (mechanical) position.
When the Spray switch is turned off, the engine reduces to an idle speed. Once ULV
sprayer is warmed up, the throttle should be set to the desired RPM or pressure at which
the applicator wishes to atomize the chemical material.
7. Green LED when illuminated implies the pump switch is in the ON position and if the
sprayer is running, the pump will run and insecticide or flush solution will flow through
the sprayer to be atomized.

16
AIR PRESSURE GAUGE
The air pressure gauge is a glycerin filled type with a pressure
range from 0-15 psig. When the engine is running and throttle
adjusted to the desired engine RPM, atomization nozzle back
pressure is most often the overriding factor in assuring correct
atomization of a given flow rate or range of flow rate. Back
pressure is measured from a fitting on the cross over tube
through a short flexible hose to the gauge.
PRESSURE SWITCH
A pressure switch is located on the side wall of the “Wet” section of this ULV sprayer. Attached
to it is a section of flexible hose back to a fitting located on the crossover tube. The purpose of
this pressure switch is to ensure the insecticide pump cannot be inadvertently turned on without
sufficient air pressure. If this was to occur, the pressure switch does not allow the circuit to
“make” thus the insecticide pump will not run. The pressure switch can be overridden by
asserting the toggle switch on the back end of the pump’s electronic enclosure (toggle up)
allowing the pump to run regardless if back pressure is present or not.
FORMULATION FILTER
Products to be atomized through this ULV sprayer must be
filtered before it is drawn through the insecticide pump to ensure
uniform fluid consistencies and prevent contamination and
potential particulate damage. The glass filled polypropylene
filter assembly consists of 4 pieces; top, bottom, gasket, and
stainless steel 80 mesh screen element. Check this filter often or
no less than once per hundred hours of operation. If you find
that the filter is collecting more and more contaminants, consider
cleaning and flushing the formulation tank more often.
FORMULATION TANK
15 U.S. gallons (56.7 liters) is the capacity of the formulation tank installed on this ULV sprayer.
The black high density polyethylene (HDPE) tank is suitable for all known products used in Vector
control and is engineered for prolonged periods of UV exposure. Additionally, the formulation
tank is supplied standard with a 2 inch threaded cap and a 3-piece Pad locking mechanism for
security concerns (pad lock not included).

17
INSECTICIDE PUMP
The standard pump supplied with the Guardian 95 G4 sprayer is an FMI (Fluid Metering Inc.)
metering pump coupled to a 12-volt DC electric motor. This piston pump is driven by an 8-volt
regulator as recommended by the pump manufacturer. Because of the metering properties of
this insecticide pump, regulating the power to the motor ensures a steady and repeatable flow
each and every time regardless of possible fluctuations in input power. This standard pump
configuration is consider a “Fixed” flow method as the amount of product pumped through the
system and to the atomization nozzle is fixed at a user’s predetermined rate. Variable flow
models of this FMI pump and other types of variable flow pump control systems are available.
PULSE DAMPENER
The FMI insecticide metering pump is a “piston” type pump that has 2 variables associated with
controlling flow. The RPM of the DC motor is a variable that is controlled through the 8V
regulator; the second variable being the angle of the piston itself. Generally speaking, the greater
the piston angle (away from the centerline of the pump), the greater the pulsations that are
generated with each and every pump revolution. For optimal atomization results, a smooth even
linear flow is desired through the nozzle. The pulse dampener traps air inside the bowl which
buffers each pulsation which smoothes out the pumps discharge to a non-turbulent, steady flow.
FLUSH TANK AND VALVE
Some formulations are best not left inside the pump and valves for prolonged period of non-use
due to corrosion and formulation thickening. To clean the insecticide pump and valve, a flushing
solution is pumped through both the 3-way valve and pump and atomized through the nozzle to
clear away residuals remaining inside. A 1.5 Quart flush solution tank is located next to the
insecticide pump; ensure it is filled with a flushing solution before use if flushing is desired. Not
all formulations require flushing but as a general rule, flushing is recommended after each use.
To flush out the spray system after use, with the engine running, assert the toggle switch (lower
right) on the operator’s control pendant to the FLUSH position illuminating the yellow LED next
to it. Turn the spray switch to the ON position. Flushing solution will begin atomization through
the sprayer. Turn the spray switch to the OFF position after the operator is satisfied that
sufficient time has elapsed to clean out the fluid system. Turn the Flush switch back to NORMAL.
ATOMIZATION NOZZLE
The atomization nozzle is designed to efficiently and effectively atomize various oil and water
based formulations to micron diameter droplet sizes as outlined on the specific formulation label.

18
Keep the nozzle clean and free from dings and dents to maintain perfect concentric alignment of
the main body and the nozzle cone. Formulation is fed through the rear of the nozzle by way of
a stainless steel tube exiting from the closest 90° elbow to the nozzle. The nozzle
swivels 360° horizontally and 360° vertically to position the nozzle at the desired attitude. The
most common nozzle position is pointed directly toward the back with an upward 45° degree
attitude.
