4. Checkeachconnectiontomakesureitistight.
5. TurntheconcentratorOn().
NOTE:AdjusttheconcentratortoMAXIMUMratedliterflowto5L/min.
NOTE:Waitapproximatelyfiveminutestoallowsystempressurestoachieveproperequilibrium
beforetesting.
6. Thepressureintheconcentratorshouldrisewithin20secondsto21p.s.i.g.±0.3and
shiftthe4‐wayvalvetotheoppositesievebed.
7. Afterthe4‐wayvalveshift,thepressureintheconcentratorwilldropto12p.s.i.g.±2
beforerisingwithin20secondsto21p.s.i.g.±0.3andshiftthe4‐wayvalvetothe
oppositesievebed.
8. Ifpressurereadingis21p.s.i.g.±0.3whenbothvalveshiftsaremade,proceedtoSTEP

9. Ifpressureintheconcentratordoesnotfallintothespecificationslistedabove,refer
toTroubleshootingonpage 16.
10. Turntheconcentratoroff(O).
11. DisconnectpressuregaugefromtheHomeFillportandreinstallplug.
