To replace the APU, reverse the steps above, except for special instructions as
follows:
To reconnect gas hose, do not use any sealing compounds or gas pipe dope
because flare fittings are designed with compression seals that eliminate the
need for these sealants.
CAUTION: Before performing full test, perform a gas leak test
on the flexible hose flare fitting when cranking or
running APU using a leak detection solution (30%
dish soap in a non-hard water solution). This test
MUST be performed to comply with NFPA 54 section
4 regarding proper gas leak and pressure tests.
