Operation
1. Add at least 500 litres of clean water to the main
spray tank. Initially there needs to be a sufficient
amount of water in the tank in order for the
pump delivery to create the venturi effect via the
venturi fitting. This will also ensure that agitation
takes place when the remaining water is added.
2. Lower the hopper for convenience. (Check that
the delivery hose to the hopper is not restricted
or kinked).
3. Open the hopper flip valve on the pressure
manifold side of the EZ control station.
4. Leave the ball valve under the hopper closed and
(if required) open the supermix agitator flip valve
on the EZ control station.
5. Operate the pump at the speed necessary to
generate at least 80 PSI delivery pressure (as
displayed on the sprayer pressure gauge). Do not
run it faster than 540 RPM.
NOTE: The higher the pump delivery pressure,
the greater the venturi suction and the quicker
the hopper will transfer the chemical. The delivery
pressure should not exceed 120 PSI as determined
by the pressure relief valve setting.
7. Put the required amount of chemical into the
hopper (liquid or granular). Wear the necessary
protective clothing and use the required safety
equipment to avoid exposure to chemicals.
8. Open the hopper tank ball valve at the bottom
of the hopper by turning the red handle up. The
chemical should be now transferring to the main
spray tank.
9. Rinse all chemical drums and the hopper as per
the rinsing instructions.
When finished using the hopper:
• Close the hopper tank ball valve at the bottom of
the hopper by turning the red handle so that it is
horizontal.
• CLOSE the hopper flip valve.
• Ensure that the agitator valve is OPEN. The
sprayer should always be agitating until spraying
begins.
• Raise the hopper to its transport position and
replace the retaining pin and ‘R’-clip in the
mechanism.
Rinsing
RINSING FROM EXTERNAL SOURCE
To rinse the Induction Hopper and chemical drums
with fresh water from the external water delivery
station:
NOTE: Spray pump must also be operating.
1. Lower the hopper. (Check that the delivery hose
to the hopper is not restricted or kinked).
2. Make sure that all valves on the EZ control fill
manifold side are OFF.
3. Make sure that the Hopper Rinse valve on the
top of the hopper is OFF.
4. Connect the fresh water fill hose to the quick-fill
coupling.
5. Operate the fresh water pumping system
between 70 and 100 PSI.
6. Open the hopper flip valve on the pressure
manifold side of the EZ control station.
7. Open the hopper tank valve at the bottom of the
hopper by turning the red handle up.
8. To rinse the hopper, turn the hopper rinse tap on
the top of the hopper ON. Close this valve when
the hopper has been rinsed.
When the hopper is empty:
• Turn the hopper tank valve at the bottom of the
hopper OFF by turning the red handle so that it is
horizontal.
• CLOSE the hopper flip valve.
