Pressure Filter Cleaning; Decontamination - Goldacres Crop Cruiser G6 Operator's Manual

Pressure Filter Cleaning

There are 2 in-line pressure filters in the spray
pressure line that traps the minute particles that are
not collected by the main suction filters.
To drain these filters, open the ball valve located at
the bottom of the filter body and let drain. Always
remember to stand aside as they may contain some
chemical residue.
Allow the chemical in the filter to dribble out
into a suitable container to avoid environmental
contamination.

Decontamination

Decontamination of your spraying equipment is
important when changing chemicals or application
methods.
Information specific to your circumstances, the
spraying equipment being used and the chemicals
being applied should be provided by your
agronomist or chemical supplier.
Always wear the recommended personal protective
equipment and use caution while working with
chemicals.
BASIC DECONTAMINATION
1. Fill the main spray tank with approximately 1000 L
of fresh water.
2. Lower the induction hopper and put the
appropriate amount of decontaminating agent
into it.
3. Turn on the agitation jet on the hopper and
allow it to fill the hopper to the top. Once
full, turn the jet off and leave the hopper to
sit for a few minutes. This is to ensure that the
decontaminating agent fully neutralises any of the
chemicals that were in the hopper.
4. Use the venturi to induct the contents of the
hopper into the main spray tank.
5. Recirculate the decontaminating agent through
the system while the main tank rinse nozzles are
running (pressure supplied from the main spray
pump e.g. pressure delivery manifold).

6. Turn off all taps to allow the pressure relief valve
to blow off and purge the 'relief to tank' line.
7. Operate induction equipment (if fitted), with a
quantity of fresh water in order to flush venturi
system.
8. Once complete, drain chemical induction hopper
delivery hose externally.
NOTE: Lower the hopper and open the lid to allow
it to drain completely.
9. Turn on Boom Recirculation to flush all boom lines
back to main tank.
10. Once the main tank has emptied, flush the
system again using fresh water to ensure the
decontaminating agent is removed from the
system.
11. Once the main tank is empty, the hose between
the tank and the suction filter also needs to be
drained. Close the valve on the Suction Filter.
12. Remove the filter bowl. As per filter removal
instructions.
13. Return switch to main chemical tank. Stand
clear of the filter when turning the valve to main
chemical tank as chemical will be coming out.
Catch all of the chemical in a suitable container so
it can be disposed of in the correct manner.
