Sump First and Last ADC2220/1150
Machine Damage Risk:
Seals in the hydraulic fan motor can be damaged if the return
line is pressurized. Always connect the SUMP hose first and
disconnect it last. The sump hose has a larger (1.06 inch)
quick-connect coupling.
Refer to Figure 16
Note: For proper hydraulic flow, use a poppet-style,
Pioneer quick coupler to connect sump hose to
tractor.
Green (hose grips) or Orange (ties): Auger/Marker (&
Fold on ADI)
Connect orange-coded hoses to tractor outlets capable
of continuous flow (although less than required for the
fan). This circuit is used by the cart for the auger, and
may also be directed to rear ports A and B for use by
Markers (not all implements have Markers).
A diverter valve on the cart ( in Figure 15) switches flow
between auger and rear ports.
Blue: Implement Lift
Connect blue-coded lift hoses to tractor outlets. This
3 ⁄
8
inch hose circuit is unused by the air cart, passing
through to rear ports C and D. It is used for Lift by all
implements.
