Troubleshoot — Reservoir will not fill

Contents

    #1: Zipper Open

    Make the zip­per (locat­ed on the side oppo­site the valve assem­bly) is closed. if it is open it will cause the bag to emp­ty. Zip to closed position.

    #2: Oxygen Fill Hose Connection

    The oxy­gen fill hose should con­nect the out­put on the air sep­a­ra­tor to the valve assem­bly on the reservoir.

    Make the fill-tube is not pinched. It is com­mon for exer­cise equip­ment to pinch the fill hose.A pinch will usu­al­ly cause the fill tube to pop off of the air separator.

    Con­nec­tions should appear as shown.

    #3: Air Separator Low/Misadjusted

    The oxy­gen flow meter should be set to 10 LPM.

    If it is too low, the reser­voir will fill slow­ly. If it is too high, oxy­gen con­cen­tra­tion may be below optimal.

    If oxy­gen is not evi­dent in the flow meter, the air sep­a­ra­tor is not work­ing prop­er­ly. There is like­ly a dis­con­nect­ed, kinked or dam­aged inte­ri­or hose.

    #4: Oxygen not evident in flow indicator

    When the ball does not float

    • Obstruc­tion (pinched air tube)
    • Dis­con­nect­ed hose inside air separator
    • Flow adjust­ment con­trol turned far right (twist left)
    • Air sep­a­ra­tor off?

    This image shows the ball indi­cat­ing 0 LPM flow rate. It is not float­ing left of the green arrow.

    #5: Pinch Test

    Pinch the out­put tube with your fin­ger. This should cause the ball to drop drop to zero briefly as flow stops. 

    • Pres­sure builds up in the machine and the hose will pop-off of the attach­ment fitting.
    • If this occurs oxy­gen is flow­ing to the reservoir.
    • If the pinch test fails then a hose inside the air sep­a­ra­tor detached.

    Fol­low these instruc­tions to find and repair the connection.

    #6: Tear or Gap Failure

    The reser­voir may have a tear:

    1. Inspect the perime­ter seam on the reser­voir around the large, +O2, stor­age com­part­ment. There should be no open­ings except the zip­per, which should be ful­ly closed. (There should be a gap in the ‑O2 com­part­ment to vent excess hypox­ic air).
    2. Inspect the fab­ric for gash­es or cuts. 

    There should be no open­ings except in the ‑O2 compartment. 

    Diagnose Internal Failure

    This pro­ce­dure is only nec­es­sary after dam­age in trans­port. LiveO2 units are test­ed before ship­ment inter­nal con­nec­tions are secured. 

    Step-1: Remove Top Panel

    Locate and open the hatch on the top of the air separator.

    Step‑2: Remove the tray

    • Remove the screw locat­ed at the front of the tray. 
    • Lift out the tray

    Step‑3: Inspect for disconnected internal hoses

    Due to some of these com­po­nents being pres­sur­ized, this may cause them to pop off. Hose clamps to assure a secure inter­nal connection.

    Step‑4: — Inspect for internal kinks:

    Check for any kinks in the hose con­nec­tions. This image shows a defor­ma­tion but not a kink. This is normal.

    If a hose is kinked, try to adjust it so oxy­gen can flow properly.
