TASK 29-14-00-614-002
Pressurization of the Hydraulic Reservoirs through the Ground Connector
1. Reason for the Job
__________________
To pressurize the hydraulic reservoirs through the ground connector.
NOTE : The reservoirs are pressurized through the air pressurization
____
manifold, thus they are pressurized at the same time.

Subtask 29-14-00-614-050
A. Pressurizing NOTE : If the message HYD B RSVR LO AIR PR is shown on the upper ECAM DU
____ after you have completed the task, you must open and close the CB 2386GH, HYDRAULIC/B RSVR/PRESS/XMTR on panel 121VU, location P34 to reset the system.
(1)
Remove the cap from the ground connector.
(2)
Connect the FILL UNIT - AIR (98D29003501000) to the ground connector. NOTE : If the pressurizing tool is not available, you can use an
____ alternative supply of air. The supply must have a pressure of 5 bar (75 psi) and it must have a filter of 5 microns or better.
(3)
Turn the nut counterclockwise to open the ground connector.
(4)
Fill the reservoir with air until 50 psi is shown on the reservoir pressure gages 1383GM, 2383GM and 3383GM.
(5)
Turn the nut clockwise to close the ground connector.
(6)
TORQUE the nut to 0.15 m.daN (13.27 lbf.in). NOTE : Obey the limits (Ref. TASK 29-10-00-200-002), if there is a
____ decrease of the air pressure in the reservoirs.
