BoomPrime (optional)
BoomPrime is a low pressure circulation system, which primes the spray boom tubes prior to spraying, ensuring a
homogeneous fluid in the boom tubes and in the MainTank. Below the illustration shows the BoomPrime system for the
boom. Components are explained in the diagrams for the liquid systems.
•
The BoomPrime system is attached to each end of a boom section (A).
•
The boom spray sections are fed into the middle of each section (B).
Liquid for BoomPrime is led through a valve (D) just before the flowmeter (F). This valve operates in opposite phase:
When priming, the direction of the liquid flow will be reversed. The liquid will be fed into the nozzle pipes from each end,
and they will then return any water back to the MainTank through the return hose for the distribution valves (C).
The BoomPrime pressure is adjusted by the handle on the control valve (E), which includes a pressure gauge.
For adjustment, see the section “BoomPrime Adjustment (Manual Version)” on page 86.
