Operation
WARNING: It is critical that the chemical probe
venturi continues to operate for a minimum of
30 seconds following use. This will ensure that no
chemical is left in the line prior to the probe being
disconnected.
NOTE: This item is intended for the induction of
liquid chemicals only.
CHEMICAL PROBE OPERATION
1. Add 20 percent of the tank's volume 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 filler.
2. Ensure that the red handle on the pump 3-way
valve is pointing towards the suction hose coming
from the main tank sump.
3. Connect probe via cam lever fitting. Close all ball
valves and set pressure to 110 PSI.
4. OPEN the venturi and agitator valves.
5. Close the bypass and induction hopper valves.
6. Operate the pump at the speed necessary to
generate at least 85 PSI delivery pressure (as
displayed on the pressure gauge mounted on the
side pod). Do not run faster than 500 RPM. The
higher the pump delivery pressure, the greater
the venturi suction and the quicker the probe
will transfer the chemical. The delivery pressure
should not exceed 100 PSI as determined by the
pressure relief valve setting.
7. Place probe in chemical.
8. OPEN the valve on the probe.
9. The chemical should be now transferring to the
sprayer tank via the venturi filler.
10. When all of the chemical has been transferred,
rinse the chemical container with water and
transfer the rinsate to the sprayer tank via the
probe. This should ensure that the entire chemical
is transferred and that the probe, venturi filler and
connecting suction hose are cleaned. Induct clean
water to rinse probe vacuum hose.
11. When finished, CLOS the valve on the probe
and venturi valve. OPEN the bypass valve. Keep
the agitator valve OPEN and disconnect probe.

Once chemical has been transferred into the
main spray tank the sprayer should always be
agitating until spraying begins.
