Subtask 28-21-52-941-066-A

A. Safety Precautions

WARNING: OBEY THE FUEL SAFETY PROCEDURES.

(1) You must obey the fuel safety procedures when you do work on the fuel system (Ref. AMM TASK 28-00-00-910-001).
(2) Put the SAFETY BARRIER(S) in position.

Subtask 28-21-52-650-061-A

B. Fuel Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Defuel the applicable wing tank (Ref. AMM TASK 28-25-00-650-001) or transfer the fuel from the applicable wing tank (Ref. AMM TASK 28-25-00-869-001).
(3) Do the EIS start procedure (upper ECAM DU and lower ECAM DU only)
(Ref. AMM TASK 31-60-00-860-001).
(4) In the cockpit, on the ECAM control panel, push (in) the FUEL system-page button.

CAUTION: BEFORE YOU CLOSE THE CROSSFEED VALVE, MAKE SURE THAT THE FUEL PUMP(S) IS(ARE) OFF. THIS WILL PREVENT DAMAGE TO THE CROSSFEED VALVE.

(5) In the cockpit, on fuel panel 40VU, release (out) the X FEED pushbutton switch (the ON and OPEN lights go off).
(6) In the cockpit, on the ECAM lower Display Unit (DU), make sure that the X FEED valve indication shows the green cross-line (closed).
(7) In the cockpit, on the ECAM control panel, turn the LOWER DISPLAY switch counterclockwise to the off position:
(a) Make sure that the ECAM lower DU goes off.
(8) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
(9) Drain the remaining fuel from the applicable wing tank (Ref. AMM TASK 28-25-00-650-003).
