Air and Oxygen Inlet Regulator Rebuild
Figure 2-6 Inlet Regulator Rebuild
To remove/install the Air and Oxygen Inlet Regulator, follow the
procedures in Section 4 of this manual, “Removal of Servo Valves,
Regulators, Inlet Block and Flow Sensor Block”.
NOTE: Inlet Regulators must be outside of the V
entilator for dis-
assembly and re-assembly.
To install the Air and Oxygen Inlet Regulators Rebuild Kits, refer to
Figure 2-6 and do the following:
1 Unscrew the brass cover from the regulator (no tool should be
needed) and remove the spring, diaphragm, diaphragm
washer, seat with O-ring, small spring, and ball (see Figure
2-6).
2 Replace the used parts, reversing the disassembly, with the
parts from the Regulator Rebuild Kit P/N (RRK1800P).
NOTE: The Regulator must be in a vertical position in order to
reassemble the Kit components.
3 Install the Regulator brass cover, hand tight and ensure all
components are aligned.
NOTE: This procedure is the same for both the air and the oxygen
regulators.
