A. Fill the Hydraulic Reservoirs (Refer to the Tables)
(1) Remove the hand pump lever 3270GM from the service panel of the Yellow hydraulic system.
(2) On the service panel of the Green hydraulic system, connect the hand pump lever 3270GM to the shaft of the hand pump 1009GM.
(3) Remove the flexible hose 1699GM from the service panel compartment of the Green hydraulic system.
(4) Remove the blanking cap and connect the flexible hose to the fill valve 1698GM. Put the other end in the CONTAINER - HYDRAULIC FLUID RESISTANT with the Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
(6) Make sure that on the quantity indicator 1834GQ the colored light of the related system comes on.
(7) Get the reservoir temperature using one of the methods:
(a) Read out reservoir temperature through ACMS RTM (Real Time Monitoring) and use the related AIDS label call-up:
1 For the reservoir of the Green hydraulic system - 029/1/172/01/08,
2 For the reservoir of the Yellow hydraulic system - 029/1/172/10/08,
3 For the reservoir of the Blue hydraulic system - 029/1/172/11/08.
Refer to (Ref. AMM TASK 31-36-00-740-008) to get access to the parameter call-up menus.
(b) As an alternative to previous method, use the THERMOMETER-INFRARED to record the hydraulic fluid temperature.
(8) Fill the hydraulic reservoir:
(b) Monitor the increase of the fluid level of the related system on the quantity indicator and do these steps:
1 Stop the flow of the hydraulic fluid when the pointer is almost to the fill level given in the table 2 (HYDRAULIC RESERVOIR FILLING CAPACITIES).
2 Slowly continue to fill again, until the pointer shows almost to the fill level given in the table 2 (HYDRAULIC RESERVOIR FILLING CAPACITIES).
HYDRAULIC RESERVOIR FILLING CAPACITIES
3 After servicing of the reservoir, refer to previous work step:
(11) Make sure that the colored light on the quantity indicator 1834GQ goes off.
(12) Remove the flexible hose and install the blanking cap on the pump.
(13) Put the flexible hose back in position in the service panel compartment of the Green hydraulic system.
(14) Remove the hand pump lever 3270GM from the hand pump 1009GM. Then put the hand pump lever in position on the service panel of the Yellow hydraulic system.
(15) If you filled the hydraulic reservoir after:
5. Close-up(1) Remove the hand pump lever 3270GM from the service panel of the Yellow hydraulic system.
(2) On the service panel of the Green hydraulic system, connect the hand pump lever 3270GM to the shaft of the hand pump 1009GM.
(3) Remove the flexible hose 1699GM from the service panel compartment of the Green hydraulic system.
(4) Remove the blanking cap and connect the flexible hose to the fill valve 1698GM. Put the other end in the CONTAINER - HYDRAULIC FLUID RESISTANT with the Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) .
NOTE: Do not use the Phosphate Ester Hydraulic Fluid-General Power - - (Material No.02ABA1) for outside air temperature on ground below -40 deg.C (-40 deg.F).
NOTE: It is not permitted to use high-density fluid Skydrol 500B-4 for A320NEO family.
(5) Turn the selector 1134GQ to the position that is correct for the system you will fill. (6) Make sure that on the quantity indicator 1834GQ the colored light of the related system comes on.
(7) Get the reservoir temperature using one of the methods:
(a) Read out reservoir temperature through ACMS RTM (Real Time Monitoring) and use the related AIDS label call-up:
1 For the reservoir of the Green hydraulic system - 029/1/172/01/08,
2 For the reservoir of the Yellow hydraulic system - 029/1/172/10/08,
3 For the reservoir of the Blue hydraulic system - 029/1/172/11/08.
Refer to (Ref. AMM TASK 31-36-00-740-008) to get access to the parameter call-up menus.
(b) As an alternative to previous method, use the THERMOMETER-INFRARED to record the hydraulic fluid temperature.
NOTE: Measure the temperature on the lower part of the reservoir in the range of the fluid level.
(c) As different alternative use the OAT (Outside Air Temperature), if the aircraft was parked for last 3h before servicing.(8) Fill the hydraulic reservoir:
CAUTION:
MAKE SURE THAT YOU DO NOT PUT TOO MUCH FLUID IN THE RESERVOIR. IF THE RESERVOIR IS TOO FULL, YOU CANNOT PRESSURIZE IT SUFFICIENTLY. LOW AIR PRESSURE CAN CAUSE THE MESSAGE "RSVR LO AIR PR" TO SHOW IN FLIGHT ON THE UPPER AND LOWER ECAM DISPLAY UNITS.
(a) Operate the hand pump 1009GM. (b) Monitor the increase of the fluid level of the related system on the quantity indicator and do these steps:
1 Stop the flow of the hydraulic fluid when the pointer is almost to the fill level given in the table 2 (HYDRAULIC RESERVOIR FILLING CAPACITIES).
2 Slowly continue to fill again, until the pointer shows almost to the fill level given in the table 2 (HYDRAULIC RESERVOIR FILLING CAPACITIES).
NOTE: Each open MLG door decreases the volume in the green reservoir by 0.25 l (0.0660 USgal).
NOTE: Each open cargo door decreases the volume in the yellow reservoir by 0.2 l (0.0528 USgal).
NOTE: After servicing of the reservoir with the temperature adjustment instruction, the cockpit reservoir filling level is permitted to be above the normal filling range, if the reservoir gauge on the ground service panel is in permitted range.
NOTE: The temperature of the hydraulic fluid can change when you use different method of measurement. The differences agree with the tolerance.
