Flushing Procedures
1. Disconnect the inlet line from the tank pick-up tube
fitting and twist off the pick-up tube.
2. Take the tank pick-up tube and place it in any
container suitable for your flushing solution.
3. Snap the quick connect inlet line back to the pick-up
tube and flush by:
3a. Running the machine in Cal Mode, (this
runs the pump without the spray head running,
flushing back into a container). (See
SmartFlow II section for more details.) This
procedure in Cal Mode is convenient because
there is no need to ramp up the spray head
and you don't need to be outdoors. Separate
care may be needed to change or flush
the sleeve. It is recommended to spin dry
the sleeve if flushed.
4. Or, flush through the sleeve by running the
machine outdoors at normal speed. Keep
in mind that for some initial period during
flushing, the pure insecticide remaining in the line
(between the pump and the spray head)
will be dispensed from the sprayer. Therefore, during
flushing the spray vehicle should be
moving forward just as it would during a
spraying operation.
4a. Always make sure that the Hub with sleeve is
secured before running the spray head to avoid
over-heating.
5. If you are not using the machine for long periods
of time, flushing is recommended to keep lines
and the sleeve clean. A quick way to purge is to
utilize the
PARK/PURGE fitting. PARK/PURGE
empties the line of chemical but also allows you to
save the chemical (before a flush process dilutes it).
Hook up the tank line to the Park/Purge fitting.
By hooking the quick connect to this Park/Purge
fitting air is allowed into the otherwise sealed quick
connect fitting, thus letting chemical to be purged
and lines and sleeve are pumped dry.
FLUSHING
NOTE: Some insecticides are corrosive to metals
or attack plastics; others become gummy if left
in the insecticide lines, pump and sleeve. If the
insecticide becomes gummy, the porous sleeve
on the Pro-Mist Dura ULV Sprayer will clog.
Therefore, it is important that you spin dry the
sleeve at the end of every spray run, i.e. run
the spray head with no chemical flow. Also, if
you are not using your sprayer on a daily basis
either spin dry the sleeve or flush the insecti-
cide delivery system with mineral oil (if using
oil-based insecticide) or windshield washer fluid
(for water-based insecticides). This will minimize
problems caused by residues of insecticides.
