BoomPrime (optional)
BoomPrime is a low pressure circulation system, which primes the spray boom tubes prior to spraying, ensuring a
homogenous fluid in the boom tubes and in the main tank. 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 taken from a bypass valve (D) just before the flowmeter. This valve operates in opposite phase:
When priming, the direction of liquid flow will be reversed. The liquid will be fed into the nozzle tubes from each end, and
they will then return any water back to the main tank through the EFC section valves dump line (C).
The BoomPrime pressure is adjusted by the handle on the valve (D), which comprises a pressure gauge.
See “BoomPrime Adjustment (optional)” on page 44 for adjustment.
