    • For CM models, the pressure knob is located on the left in place of the timing knobs pictured here.

    • Procedure can be found in the attached document.

    • Block the connector on the front of the machine using a rubber plug or similar item.

    • Check the pressure gauge. If it is not zero, see “pressure gauge reading is wrong” on the troubleshooting guide.

    • Set the inhale pressure knob fully clockwise, and the inhale flow and pressure knobs fully counterclockwise. On the CA models, set the manual/auto switch to manual, and set each timing knob to 1 second.

    • Turn on the power switch, checking that the light under it turns on. If not, see “indicator light won’t turn on” in the troubleshooting guide.

    • Turn the pressure knob slowly clockwise, noting that the speed of the motor increases steadily. Once it’s fully clockwise, allow the unit to warm up for 1 to 2 minutes.

    • Reset the pressure knob counterclockwise, then set the control lever to inhale and check that the gauge reads between 2 and 5 cmH2O.

    • Move the control lever to exhale and note that the gauge reads between -2 and -5 cmH2O.

    • Repeat the inhale and exhale tests with the pressure knob fully clockwise, seeing if the gauge is between 57 and 63 cmH2O.

    • Release the control lever and note that the lever moves to the center and pressure drops immediately to 0 cmH2O.

    • If any of these pressures are wrong, see “limited pressure” on the troubleshooting guide.

    • With the control lever on inhale, adjust the pressure knob to 40 cmH2O.

    • Turn the inhale pressure knob fully counterclockwise. Check that the gauge is between 18 and 22 cmH2O.

    • Slowly returning the inhale pressure knob clockwise should increase the pressure gradually back to 40 cmH2O.

    • 5. Turn the pressure knob fully clockwise, set the control lever to inhale, remember the gauge reading, and release the control lever.

    • Set inhale flow to minimum (clockwise). Set the control lever to inhale and check that the pressure is within 10 cmH2O below the previous reading (maximum flow).

    • Remove the rubber plug. Check the flow by pushing the control lever to inhale and feel the airflow out of the unit. Release the control lever.

    • Set the inhale flow knob fully counterclockwise, and repeat the test, checking for a large increase of airflow.

    • (The rest of this guide only applies to the CA series, not the CM series.)

    • Set the pressure knob to minimum. Move the switch from manual to automatic.

    • Verify that the unit immediately begins with the inhale pressure, followed by exhale (negative) pressure then drops to 0 cmH2O and continues to repeat.

    • Set the switch back to manual and verify that the pressure drops to 0 cmH2O. Return to auto.

    • One at a time, set each timing knob to 5 seconds and verify that each knob affects the correct phase.

    • Set the timing knobs to 5 seconds and use a stopwatch to check that each one lasts between 4.8 and 5.2 seconds.

    • Set the knobs to 1 second and verify that each phase lasts between 0.9 and 1.1 seconds.

    • If the timings are off, see “incorrect timings” on the troubleshooting guide.
