R (1) Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-R 002).

 (2) If applicable, disconnect the Power Transfer Unit (PTU) (Ref. TASK 29-23-00-860-001).
 NOTE : The flaps move at full-speed if the Power Transfer Unit (PTU)____ is in operation. If the PTU is disconnected (electrically or hydraulically), only the yellow flap motor operates and the flaps move at half-speed.
 NOTE : An ECAM F/CTL FLAP SYS 1 FAULT message will show when the PTU____ is isolated. This message can be ignored.
 (3) Pressurize the Yellow hydraulic system (Ref. TASK 29-10-00-863-002).
 (4) Pressurize the Blue hydraulic system (Ref. TASK 29-10-00-863-003).
 NOTE : The Blue and/or Green hydraulic system(s) operate(s) the slat____ system. If necessary, use the alternative hydraulic system.
