TM  1-1520-240-10 9-2-2            NOTE Before FARE fuel transfer begins, a path from the  desired  ERFS  II  tank  to  the  helicopter main tanks must be established and the fuel should be transferred from only one tank at a time. F 5.   “T” couplings on ERFS II tanks not being transferred — CLOSE. CAUTION There is no gauge on board the aircraft to provide measurements of GPM or PSIG. The rate at which fuel is transferred from the ERFS II tanks to the Helicopter main tanks is 20 GPM. The rate at which fuel is transferred from the ERFS II tanks using the FARE pump and standard FARE trans- fer hose assembly is 84 to 88 GPM. The FARE pump is rated at 120 GPM. Suction defueling pressure should not exceed -11 PSIG.  Do  not  exceed  5  PSI  except  in extreme  emergency.  The  ERFS  II  outer container is expected to fail at 10 PSI or greater.  The  crash  resistant  bladder  will prevent spillage and fuel can still be trans- ferred. F 6.   FARE   valve   control   handle   OFF   LOAD Position. F 7.   FARE pump — ON. F 8.   ERFS II tank manually operated fuel/defuel valve — OPEN. F 9.   Once ERFSII tank empties, tank fuel man- ifold “T” coupling — CLOSE. F 10.   Next ERFS II tank fuel manifold “T” coupling — OPEN. F 11.   Next/remaining ERFS II tank manually oper- ated fuel/defuel valve — OPEN. F 12.   Once ERFS II tank empties, tank fuel man- ifold “T” coupling — CLOSE. F 13.   FARE pump — OFF. 9-2-10.  FARE  Pump  Failure  During  Ground  FARE Refueling Operation. F 1.   Filters — Remove. F 2.   Overwing nozzle — Install and use. F 3.   Manually  operated  fuel/defuel  valves  — OPEN. NOTE If three ERFS II tanks are installed and all the in-tanks are on, a 60 gallon per minute rate can be achieved. F 4.   ERFS II tank pumps — ON. 9-2-11.  EAPS  1  FAIL  and/or  EAPS  2  FAIL  Caution Light ON. 1.   EAPS DOORS switch (affected engine) — OPEN. 2.   EAPS FAIL: caution capsule — Check out. F 3.   EAPS  BYPASS  DOORS  OPEN  light  — Verify light is ON.
