SECTION 2—CONCENTRATOR VERIFICATION AND MAINTENANCE
SECTION 2— CONCENTRATOR VERIFICATION
AND MAINTENANCE

Performance Verification

NOTE: A dedicated concentrator should be used to test HomeFill II compressors.
NOTE: The test concentrator MUST have its performance verified and documented prior to
testing HomeFill II compressors.
NOTE: All performance verification and maintenance performed on the test concentrator MUST
be documented on a log sheet that is attached to the concentrator.
1. Turn On the concentrator and set the flow rate to 5 L/min.
2. Allow the concentrator to warm up for a minimum of 30 minutes.
3. After the 30 minute warm-up, check the oxygen concentration using a calibrated
oxygen analyzer.
NOTE: The oxygen concentration reading MUST be above 90% at 5 L/min.
4. Provided the oxygen concentration is 90% or higher at 5 L/min., record the following
on the repair statement and on the test concentrator maintenance log:
A. Date of the performance test and when any service is performed.
B. Hour meter reading.
C. Oxygen concentration.
D. If service is performed, record all details of repair, including preventative
maintenance.
E. Record all parts replaced, and list all detailed performance results.
NOTE: A new entry MUST be made for each performance test, or when any service type items are
performed.
5. Turn the concentrator flow rate down to 3 L/min.
6. Connect the test concentrator to the HomeFill II compressor to be tested. Refer to
Connecting the Compressor to the Concentrator on page 12.
7. Test the HomeFill II compressor. Refer to Troubleshooting/Cylinder Fill Times on
page 47.

Connecting the Compressor to the Concentrator

NOTE: For this procedure, refer to FIGURE 2.1 on page 13.
1. Insert one end of the interconnect hose into the outlet fitting on the back of the
concentrator (Detail "A").
2. Insert the opposite end of the interconnect hose into the inlet fitting on the side of the
compressor (Detail "B").
