NOTE: The values listed above will vary with tank pressures. Conditions will vary with tank pressure, hose size,
withdraw valve size, fittings/or adapters that restrict flow to the heat exchanger.
*To prevent the orifice from plugging, a 40 mesh strainer may be needed in front of the orifice inlet.
CALCULATING THE REQUIRED CAPACITY
Use the formulas below to determine the orifice and cooler configuration for the desired application rate, speed,
and implement width.
To convert to GPM:
lbN/min = GPM
4.22 ......................... (EQ 9)
Target Rate (lbN per acre) x Speed (mph) x Implement Width (inches) = lbN/min
5940 .......................... (EQ 10)
To convert lbN/Hr:
lbN = lbN/min
min x 60 .......................... (EQ 11)
INSTALLING AND ORIFICE HOSE BARB FITTING
1. Follow the system bleed down procedure found in the AccuFlow manual before disassembly.
2. Remove the EVA hose from the hose barb.
3. Remove the current hose barb from the refrigerant inlet port.
4. Apply thread sealant to orifice hose barb fitting and re-install into refrigerant port.
5. Reinstall the hose onto the orifice hose barb fitting and secure with a hose clamp.
