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) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.

B. Aircraft Maintenance Configuration

NOTE: This procedure also gives step(s) for the aircrafts with the ACT(s) installed. You can ignore the step(s) if it is not applicable for you.

(1) Make sure that each wing contains a minimum fuel level of 1800 kg (3968.3 lb). Make sure that each wing tank outer cell is full of fuel. If required, refuel the aircraft (Ref. AMM TASK 12-11-28-650-003) to get the minimum fuel level.
(2) Make sure that the refuel panel door is open and the MODE SEL switch (on the panel 800VU) is in the REFUEL position.
(3) Energize the ECAM system (Ref. AMM TASK 31-60-00-860-001).
(4) On the ECAM control panel, push (in) the FUEL pushbutton switch (P/BSW).
(5) On the ECAM System Display (SD), make sure that the FUEL page is shown.
(6) On the ECAM SD FUEL page, make sure that the intercell transfer valves show closed.
(7) Get access to the SYSTEM REPORT/TEST Menu Page (Ref. AMM TASK 31-32-00-860-001).
