C. Aircraft Maintenance Configuration
WARNING : OBEY THE HYDRAULIC SAFETY PROCEDURES.
_______
(1)
Obey the hydraulic safety procedures (Ref. TASK 29-00-00-910-002).
(2)
Depressurize the Green, Yellow and Blue hydraulic systems and put them in the maintenance configuration (Ref. TASK 29-00-00-864-001).
(3)
Put warning notices to tell persons not to pressurize the hydraulic systems:
-in the flight compartment near the hydraulic section 40VU of the overhead panel,
- on the ground service panels of the Green, Yellow and Blue hydraulic systems.
(4)
Depressurize the reservoirs of the Green, Yellow and Blue hydraulic systems (Ref. TASK 29-14-00-614-001).
(5)
Remove the blanking cap from the reservoir-pressurization ground connector (referred to as ground connector) on the reservoir pressurization unit 1360GM.
(6)
Connect the FILL UNIT - AIR (98D29003501000) to the ground connector.
NOTE : If the pressurizing tool is not available, you can use an
____ alternative air supply. The supply must have a pressure of 5 bar (72.5 psi) and it must have a filter. The rating of the filter must be 5 microns or better.
(7) Open the ground connector.

A. Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ground air supply:
-set the supply at 5 bar (72.5
psi).
2.
Pressurize the reservoirs of the On the air pressure gages:
three hydraulic systems - the pressure in each reservoir
(Ref. TASK 29-14-00-614-002). increases to 50 psig.
3.
On the ground air supply: On the air pressure gages:
-stop the supply of air to the - the pressure in the reservoirs is reservoir pressurizing system. constant.
-disconnect the ground supply
from the ground connector but
keep the ground connector open.
4. On the ground connector:
-close the ground connector.
5. On the water separator: On the air pressure gages:
-push the drain valve in and - the pressure in the reservoirs is hold it in the open position. constant.
-release the drain valve of the
water separator and allow it to
go to the closed position.

6. Depressurize the reservoirs of On the air pressure gages:
the three hydraulic systems - the pressure in the reservoirs
(Ref. TASK 29-14-00-614-001). decreases to zero.
7. Start the APU (Ref. TASK 49-00-
