SECTION 5
PRE-OPERATION
SET-UP SPRAY PRESSURE
Croplands recommends setting the maximum system
pressure to be 10% above the chosen spray pressure which
is normally an extra 0.5 - 0.8 bar.
With the maximum pressure set, the finer adjustments are
controlled by the Fusion (auto rate) controller.
The system pressure is set via the
central red knob
of the
manual Pressure Regulator Valve (see photo 1).
The regulator will need to be adjusted from time to time –
as rates between Tier 1, Tier 2 and Tier 3 can require a
Manual Pressure adjustment.
WARNING; To set and forget at high pressure will put
undue stress / wear and tear on the system. Maximum
recommended pressure is 12 bar but 5 to 8 bar is
recommended.
To set for the first time:
• Ensure that the nozzles fitted on the sprayer are
applicable to your desired rate & recommended
operating pressure.
• Wind the pressure control knob anticlockwise to ensure
the sprayer starts up with limited pressure
• Ensure the tank selection valve is in the “SPRAY”
position
• Start the tractor (assuming the Fusion controller is fitted
and engaged, ready to spray)
• Start the pump by engaging the Tractor remote (Micro
Power Pack version) or PTO. Set to operate at your
required rpm, usually between 450 and 540 rpm
• Engage both Front and rear Agitators
• Note: The fans do not have to be engaged during this
process
• With the Fusion controller in manual mode, select the
appropriate Tier for the application rate and turn on all
the sections. Once the unit is spraying press and hold
the “UP” arrow on the screen for 10 seconds to ensure
the servo valve is in the closed / pressurised position.
• Slowly wind the pressure control knob clockwise
(if needing to increase pressure) until your required
operating pressure is reached, and add a further 10%
surplus pressure.
• Example - If the application rate is 500 L/ha and with
your row width/nozzles & spraying speed the rate is
achieved at 7 bar, you would set the maximum system
pressure to 7.7 bar
Once done, leave the manifold setting (red knob) “as is”
until a change of operating pressure is required.
