Boost Pump Hydraulic Connections
1.
Install the supplied hydraulic SAE o-ring to JIC adapters (P/N 333-0012-204) in the ‘CF’ and ‘IN’ ports of the
hydraulic PWM control valve (P/N 334-0001-042).
2.
Install the supplied SAE o-ring to JIC elbow adapter (P/N 333-0012-139) to the ‘Press.’ port of the boost
pump motor.
3.
Install the supplied SAE o-ring to JIC straight adapter (P/N 333-0012-056) to the ‘Tank’ port of the boost
pump motor.
4.
Connect the hydraulic hose assembly (P/N 214-1000-642) to the ‘Press.’ port of the boost pump motor and
‘CF’ port of the hydraulic PWM control valve.
5.
Connect the hydraulic hose assembly (P/N 214-1000-632) to the ‘IN’ port of the hydraulic PWM control
valve and route the hose to the front of the toolbar. Install the supplied elbow (P/N 333-0012-042) to the port
if necessary.
6.
Connect the hydraulic hose assembly (P/N 214-1000-633) to the ‘Tank’ port of the boost pump motor and
route the hose to the front of the toolbar, follow the same path as the hose routed in step 5.
Note:
Route hydraulic hoses so that they are free of twists or kinks and will not be pinched by
surrounding mechanisms. Take care to prevent dirt or other contaminants from entering hydraulic
assemblies which may cause premature wear or failure of hydraulic components.
7.
Install tractor hydraulic quick couplers (not supplied) to the free 1/2” NPT ends of the hoses using teflon
tape.
Checking for System Leaks
Once the AccuFlow HP™ has been installed on the implement, check the system for leaks by charging the
system with compressed air and applying soapy water to all plumbing joints and hoses. Thoroughly examine
plumbing connections for bubbles indicating any kind of leak. Fix any leaks before charging the AccuFlow™
system with anhydrous ammonia.
CAUTION
To avoid damage to boost pump seals, do not
run the boost pump dry. Be sure to shutdown
the boost pump when no anhydrous ammonia
is flowing through the pump or when the nurse
tank is empty.
