COMPRESSOR REPLACEMENT
The compressor is the "pump" within the oxygen concentrator that pushes room air into the
bottom of the sieve beds. Over time, the cup seals may wear and the compressor will not
operate properly. To replace the compressor, follow the steps below:
1. Remove the PSA assembly per the PSA REMOVAL section in this manual.
2. Stand the PSA assembly upright and loosen the center bolt using a 5/32" Allen wrench.
