A320 Hydraulic Reservoir Filling Before starting with the filling procedure, all flight control surfaces must be in their neutral retracted position, thrust reversers retracted and the cargo doors must be in the closed position.

When the flight control surfaces are retracted, place warning notices to prevent others from moving the flight control surfaces.

Select the hydraulic page on the system display and make sure that the hydraulic systems are completely depressurized.

Make sure that the system accumulator is pre-pressurized to the correct value and that the hydraulic system reservoir is correctly pre-pressurized with air.

Pressurize the yellow hydraulic circuit with the yellow electric pump.

The PTU should be in the off position to make sure only the yellow system will be pressurized.

When the electric pump is selected to off, the triple indicator should show the brake accumulator as being fully pressurized to 3000 psi.

Place a warning notice to tell people not to operate the hydraulic system.

Open the green and yellow hydraulic ground service panel.

Remove the hand pump lever from the yellow panel and assemble it so it can be used on the green service panel hand pump.

Make sure to wear the proper protection gloves and goggles before removing the flexible hose from its housing.

Connect the hose to the hand pump and insert it into a new canister of hydraulic fluid.

Select the hydraulic system that needs to be filled.

The selection is confirmed by a colored lead on the indication panel.

Install the hand pump lever on the pump and start the filling operation.

Fill the system reservoir to the last white line in the related colored band and not to the end of the scale.

Remove the hose from the hand pump and clean and dry the hose and its connections to prevent spillage.

Install blanking caps on the pump and hose.

Remove the hand pump lever and reassemble it in its stowing configuration and install it on the yellow service panel.

If a reservoir is overfilled, it must be drained.

Connect the flexible hose to the drain connector.

Do not forget to depressurize the reservoir before opening the drain valve.

Use a container of sufficient size to collect the excess fluid from the reservoir.

Open the drain connector until the required reservoir level is reached.

Remove the flexible hose and clean the connection.

Repressurize the reservoir before operation of the system.

 Remove the warning notices and check the hydraulic system page for correct level indication.
