Air regulator assembly replacement

Refer to Figure 9.2.1.
1. Ensure that power, fuel and air supplies to the instrument are disconnected. Remove
the top rear cover as described in Section 9.2 step 1.
2. Remove the compression fitting that retains the nylon tube to the outlet of the air
regulator assembly. Pull the tube and compression fitting out of the air regulator
assembly.
3. Remove the nut on the rear panel air inlet bulkhead connector. The air regulator
assembly can now be pulled forward so the connector clears the rear panel and then
remove from the instrument. Replacement is the reverse of removal.
4. Check that no air leaks are present and that the gauge can be set to 12psi with the
nebuliser connected.
