Operating the control unit while spraying
The switches on the spray control unit control the following functions:
1. Power ON/OFF
2. Spray pressure regulation
3. Main valve ON/OFF
4. Optional function
5. Optional function
6.
End nozzle (Left/OFF/Right)
7. Foam marker blob interval
8. Foam marker (Left/OFF/Right)
9. Section valves
In order to close the entire boom, switch main ON/OFF (3) to OFF position. This returns the pump output to the tank through
the return
system. The diaphragm Non-drip valves ensure instantaneous closing of all nozzles.
In order to close one or more sections of the boom, switch the relevant distribution valve (9) to off position (A). The pressure
e
qualization ensures that the pressure does not rise in the sections which are to remain open (B).
On the sprayer, the suction valve should be turned toward “Suction from Main tank” and pressure SmartValve sho
uld be
turned toward “Spraying”. Turn the agitation valve to “Agitation” if necessary.
Agitation before re-starting spraying
If a spraying job has been interrupted for a while, severe sedimentation
can occur depending on chemicals being used. When re-starting spray
job
it might be necessary to agitate sedimented material first.
1. Turn the handle at the suction valve towards “Suction from Main
tank”. Turn Pressure SmartValve “Off” (towards unused function).
Turn the AgitationV
alve towards “Agitation”.
2. Engage the pump and set P.T.O. speed at 540 r/min or 1000 r/min
(depending on pump model).
3. Agitation has started and should be continued for at least 10
minutes.
4. Onc
e the chemicals are mixed, spraying can resume. Turn pressure
SmartValve towards “Spraying” and start spraying again.
