3. Job Set-up
Subtask 28-25-00-941-089-A ** ON A/C NOT FOR ALL

A. Safety Precautions
(1) Obey the fuel safety procedures (Ref. AMM TASK 28-00-00-910-001).
(2) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
(3) Put the WARNING NOTICE(S) in position to tell persons not to operate the flight controls.

Subtask 28-25-00-860-086-B ** ON A/C NOT FOR ALL

B. Aircraft Maintenance Configuration

NOTE: There are two alternative methods to prime the ACT fuel transfer pump.
Method 1 - use the left-hand (right-hand) wing booster pumps.
Method 2 - use the fuel level in the center tank.

(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do an EIS start procedure (lower ECAM Display Unit (DU) only) (Ref. AMM TASK 31-60-00-860-001).
(3) On the ECAM control panel, push the FUEL P/BSW to show the FUEL page on the ECAM lower DU.
(4) For method 1, the wing tank must contain a minimum of 1750 kg (3858 lb) of fuel.

NOTE: If the booster pumps in the left-hand (right-hand) wing tank are primed, it is not necessary to refuel the tank. There will be sufficient fuel in the pumps/pipes to do this procedure.

(5) For method 2, the center tank must contain a minimum of 2500 kg (5512 lb) of fuel.
(6) Refuel or transfer fuel as necessary into the left-hand (right-hand) wing tank or the center tank (Ref. AMM TASK 12-11-28-650-004) or (Ref. AMM TASK 28-25-00-869-001).

Subtask 28-25-00-010-093-B ** ON A/C NOT FOR ALL

C. Get Access
(1) For method 1, do the steps that follow:

NOTE: The steps that follow are not necessary for method 2.

(a) Open the left-hand Main Landing Gear (MLG) door (Ref. AMM TASK 32-12-00-010-001).
(b) Make sure that the 460005835 SLEEVE - GROUND LOCK is installed on the left-hand MLG door-actuator.
(c) Put an ACCESS PLATFORM 2M (6 FT) - ADJUSTABLE in position in zone 147.
(d) Open access door 192MB.

NOTE: Do not keep the door open longer than necessary because the battery can discharge.

4. Procedure

WARNING: WHEN YOU OPERATE THE FUEL PUMPS DURING A MAINTENANCE PROCEDURE, A MAINTENANCE PERSON MUST BE IN THE COCKPIT. THIS PERSON MUST STOP THE PUMPS WHEN THE LOW PRESSURE FAULT LIGHT(S) (ON PANEL 40VU) COME ON, TO PREVENT OPERATION OF THE PUMPS(S) WITHOUT FUEL ('DRY RUNNING'). OPERATION OF THE PUMPS WITHOUT FUEL CAN CAUSE A FIRE.

Subtask 28-25-00-869-095-A ** ON A/C NOT FOR ALL

A. Method 1 - Left (Right) Wing-Tank Booster-Pumps used to Prime the ACT Fuel-Transfer Pump
(1) Select the wing tank that will supply fuel.
(2) In the flight compartment, on fuel control-panel 40VU:
(a) Push (in) the ACT AUTO pushbutton switch to operate the ACT fuel-transfer pump. Make sure that the FWD legend in the ACT AUTO pushbutton switch comes on.
(b) If the left wing tank will supply fuel:

Push (in) the X FEED pushbutton switch.
Make sure that the OPEN and ON legends on the X FEED pushbutton switch come on.
On the ECAM lower DU, make sure that the X FEED valve is shown open (in-line).

(c) Push (in) the L TK PUMPS 1 and 2 (R TK PUMPS 1 and 2) pushbutton switches of the wing tank that will supply fuel.
(d) On the ECAM lower DU, make sure that the related pump symbols change from an amber cross-line to a green in-line.
(3) Immediately, on refuel/defuel control-panel 800VU:
(a) Lift the guard and put the MODE SELECT switch in the DEFUEL XFR position.
(4) In the undercarriage bay in zone 147:
(a) Put a suitable ROD - NON METALLIC through the ACT-equipment support-door cover (1).
(b) Push (in) the manual plunger (2) on the ACT refuel valve (3). Hold the plunger in for approximately 10 seconds and the ACT AUTO transfer-discharge line will fill with fuel.
(c) Release (out) the manual plunger (2) on the ACT refuel valve (3). Remove the ROD - NON METALLIC from the ACT-equipment support-door cover (1).
(5) On refuel/defuel control-panel 800VU:
(a) Put the MODE SELECT switch to the OFF and guarded position.
(6) In the flight compartment, on fuel control-panel 40VU:
(a) Release (out) the L(R) TK PUMPS 1 and 2 pushbutton switches of the wing tank used to supply fuel.
(b) On the ECAM lower DU, make sure that the related pump symbols change from a green in-line to an amber cross-line.

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.

(c) If the left wing tank was used to supply fuel, release (out) the X FEED pushbutton switch. Make sure that the OPEN and ON legends on the X FEED pushbutton switch go off.
(d) On the ECAM lower DU, make sure that the X FEED valve is shown closed (cross-line).
