 On the ground, it is possible to pressurize the system from a ground supply through the self-sealing connectors on the ground service panel.
 The supply to all consumers (except the thrust reverser) goes through the HP manifold 1011GM. The HP manifold has pressure switches, a filter, a check valve, a transmitter, a solenoid valve and other components which control the system. The supply to all consumers other than the flap and slat motors, nose wheel steering, nose and main landing gears and doors also goes through the leakage-measurement system manifold 1146GM. Thus it is possible to isolate some consumers to measure the internal leakage of parts of the system.

 B. LP System The LP system returns the fluid from the consumers to the reservoir. The case drains of the EDP and PTU, and the returns from the HP manifold, are also connected to the LP system. The system has check valves where applicable to control the flow of fluid. The check valves also protect the main system if there is a leak in a subsystem. Some of the return lines are connected together at the LP manifold 1003GM. Part of the LP system is also used in the reservoir filling system.
 The LP fluid goes through the LP filter 1002GM before it gets to the
 system reservoir 1000GQ.
 A filter 1084GM is also installed in the EDP case drain line to the LP
 system.

 The system reservoir 1000GQ is installed in the main landing gear
 compartment.
 The reservoir is filled through the reservoir filling system which is
 operated from the ground service panel of the Green system. A reservoir
 drain valve is installed on the reservoir.
 The reservoir is pressurized with air to 3.5 bar (50 psi). The supply of
 air comes from the aircraft pneumatic system. It is also possible to
 pressurize the reservoir from a ground supply. A depressurization valve
 1187GM is installed on the ground service panel of the Green system.

 C. Suction System The engine pump 1030GK gets its supply of fluid directly from the Green reservoir 1000GQ. The fire shut-off valve 1046GK permits to isolate the supply of the engine pump.
