Loading Materials
To load material:
1. Connect the nurse tank hose to the quick-fill
coupler (1) at the rear of the planter.
2. Lock the hose in place with cam lock levers.
3. Close the valve going to the inline filter located
just before the pump.
Contamination Risk
Always close the valve at the inline filter when
filling or storing any liquid in the tanks. Failure
to do so may allow material to run out of the
manifold (boom) outlets causing contamination
from spillage.
4. Open the valve at the quick-fill coupler.
5. Fill the tank, then close the valve at the quick-fill
coupler.
6. Disconnect the nurse tank hose.
Orifice Plates
The orifice plate needs to be small enough to create
at least 15 psi of pressure in the manifold, but large
enough to prevent the manifold pressure from
exceeding 85 psi.
The minimum pressure is required to even out the
flow of fertilizer between rows. To reduce orifice
plugging and pump wear, use the largest orifice
practical for your fertilizer application rate.
The best pressure range to maintain is 15 to 40 psi to
ensure optimum distribution while minimizing
leakage.
Orifice size does not control rate. It is only
used to create 15 to 65 psi back pressure
for even flow between rows. Set application rate in
gal/acre using the pump drive chart.
* Standard sizes in many fertilizer bundles. Check
your accessories before ordering.
Rate Ranges vs. Orifice Size
* Recommended Rate Range in gallon per acre.
Pressure is 15-40 psi. Values based on: 5 mph and
10.7 lbs/gallon Fertilizer solution density.
