GENERAL TROUBLESHOOTING
1. Ensure that the STP pump circuit breaker is turned On.
2. Ensure that the handle on STP Adapter ball valve is pointing in the correct direction of flow. You can verify this by the
curved arrow on the handle. The arrow should be pointing to the pump port and the port that the HydrX hose is connected
to.
3. Ensure that there are no alarms on the ATG that could possibly prevent the pump from turning on (i.e. DPLLD Gross Line
Fail or Pump Shutdown Alarm).
4. Look in the Diesel STP Sump for any signs of visible leaks around the filter caps and hose connections and ensure that
flaretite seals were connected on each hose connections.
5. Check the HydrX Filter Performance screen on the FCC to ensure that the filters are not clogged. If there is a large
discrepancy between Initial and Last Pressure, the HydrX filters could be clogged.
6. Close the STP Adapter ball valve and remove both filters. Make sure that the plastic wrapping was removed from the
outside of each filter and then ensure that both filters are seated properly in the bottom of each filter compartment. The
opening on the bottom of each filter is keyed to the bottom of each filter compartment. You may need to rotate the filter to

Run ‘Fill Cycle’. After running ‘Fill Cycle’
check ‘Filter Life’ on FCC controller.
Verify line to which HydrX is assigned is
enabled and not in alarm.
If P or PO outlet pressure is positive, verify
inlet and outlet valves are wired correctly.
Verify that HydrX siphon cartridge screen
is not clogged (ref. manual 577014-478).
Check STP pressure at HydrX adapter
port.
Vacuum Leak
Run ‘Fill Cycle’. After running Fill Cycle,
vacuum level should hold below -0.75 psi.
Check drain valve seated.
Check for loose hose connections.
Check filter cover o-rings.
