Filling with liquid or granular chemicals by VACnMIX (optional equipment)
±
WARNING! Only compatible and complimentary chemicals should be mixed. When combined, incompatible
chemicals may cause a potentially dangerous reaction, or result in unwanted effects on the crop to be sprayed.
ALWAYS follow label instructions!
1. Fill the hopper with water to the 25 litre level.
μ
ATTENTION! The scale in the hopper can only be used if the
sprayer is parked at level ground! It is recommended to use a
measuring jug for best accuracy.
2. Start a swirling action in the hopper by turning ON the upper
and lower jet handles and turning Off the Fast Fill handle.
3. Pour pre-measured chemical amount into vortex stream (not
into centre of hopper). Vortex action will be reduced during the
addition of chemical.
÷
NOTE! Large unmixed chemical will be held by centrifugal
force to the outside wall of the hopper. Continue mixing in the
hopper until chemical is fully integrated into water.
÷
NOTE! Always ensure that enough pressure is maintained to
drive the vortex. A drop in level may cause air to enter the
suction line, and too high a level will cause slowing of the vortex, resulting in incomplete mixing of chemicals which
may affect the accuracy of application rates when spraying.
4. When all chemical has been thoroughly mixed, close vortex jet
handles.
5. To transfer the mixture to the sprayer tank. Close lid of VACnMIX,
turn the Vacuum Transfer Valve to the EMPTY position. This will
allow a venturi to create a vacuum inside the VACnMIX and
allow the hopper contents to flow through to the main tank.
6. With the lid still closed, flush the hopper using the hopper rinse
ring between batches of chemical.
7. After all chemicals have been added to the sprayer tank, and the
VACnMIX is empty, set the suction ball valve on the sprayer
manifold to Flush Tank in order to flush the VACnMIX system
with clean water.
8. Refill the hopper with clean water, operate all valves as in mixing
procedure, empty and repeat until the system is clear of residue
chemical.
