Removal and Replacement of Servo Valves, Regulators, Inlet Blocks
and Flow Sensor Block
Figure 4-14 Pneumatics Panel
Assembly SVO2101A
Refer to figure 4-14 and follow these steps:
1 Perform above steps for removal of pneumatic panel
assembly SVO2101A.
Note: To replace servo valves, regulators, inlet blocks or the flow
sensor block, all screws securing listed components need to be
removed.
2 Remove 4 screws, 2 each securing the air and oxygen inlet
blocks to PNL2102M.
3 Remove 8 screws, 4 each securing the air and oxygen servo
valves to PNL2102M
4 Remove 2 screws securing the flow sensor block to PNL2102M.
5 Lift all parts away from the panel PNL2102M at the same time,
then disassemble each component as needed.
6 To reassemble, reverse steps 2 through 5. Ensure the servo
vales and regulators are aligned during reassembly.
Note: If replacing either of the servo valves or regulators,
calibrations D1 and / or D2 and calibration of the regulators will
need to be performed. Refer to Section 5 for D1, D2, and regulator
calibration.
