What to do if there is condensation or water pooling up on the floor from my CAIRE Liberator 30 Oxygen Equipment?
If you notice condensation or water pooling on the floor near your CAIRE Oxygen Equipment, this may happen because water accumulates when frost melts on the coils. Ensure that the condensate bottle is installed correctly and emptied as needed; it may be full or not properly in place.
What to do if there is no flow at the oxygen outlet of my CAIRE Medical Equipment?
If there's no flow at the oxygen outlet, first check if the reservoir is empty by looking at the contents indicator/level gauge and fill it if needed. Ensure the flow control knob is not in the off ('0') position. Also, make sure the nasal cannula isn't kinked or disconnected and that the vent valve is fully closed. Check for any leaks in the system. If the relief valve is open, refer to the corrective actions for excessive venting. Clean or replace the FCV inlet filter screen if obstructed. Finally, inspect the warming coils and withdrawal tubes for blockages and replace if necessary. If none of these steps work, the FCV may be faulty and require replacement.
How to fix liquid leaks from coupled QDVs during fill of CAIRE Medical Equipment?
If liquid leaks from the coupled QDVs during the fill, the most likely cause is a worn or damaged lip seal. Replace the QDV lip seal.
What to do if my CAIRE Medical Equipment contents indicator reads incorrectly?
If the contents indicator reads incorrectly, first replace the battery if the voltage is too low, then calibrate the meter. Visually inspect the meter harness assembly for damaged sensor wires. If the indicator is not calibrated properly, calibrate it. If there's an ice crystal in the reservoir, empty and warm the reservoir to melt and evaporate moisture. Finally, inspect for physical damage and replace the meter if malfunctioning, then recalibrate.
What causes liquid leaks from the QDV poppet after filling CAIRE Medical Equipment, and how to fix it?
Liquid leaks from the QDV poppet after filling can occur due to an ice crystal preventing the QDV from closing properly. Engage and disengage the transfer line onto the reservoir several times to dislodge the ice crystal, and always ensure that the male and female QDVs are wiped clean and dry before filling. Alternatively, the QDV poppet may be dirty or damaged, requiring replacement of the QDV cartridge or the entire QDV assembly.
Why is there high pressure at the reservoir oxygen outlet of my CAIRE Medical Equipment?
High pressure at the reservoir oxygen outlet can be caused by several factors. The saturation pressure might be too high, so inspect it and allow at least 30 minutes at no flow for proper saturation. The primary relief valve might be set too high or operating improperly, requiring a relief valve test and possible replacement. The economizer valve could be stuck in a closed state, necessitating an economizer test and possible replacement. Finally, a partial or complete loss of vacuum may be the issue, requiring a NER test and possible return of the unit.
What to do if my CAIRE Medical Equipment unit will not maintain acceptable system pressure?
If your unit is not maintaining acceptable system pressure, first inspect the saturation pressure of the reservoir, ensuring it has had at least 30 minutes at no flow to saturate properly. Close the vent valve and check its outlet and stem for leaks, repairing or replacing as needed. Perform a leak check on the plumbing and repair any leaks. Test the economizer valve and replace it if necessary. Finally, test the primary relief valve and replace it if necessary.
Why is my CAIRE Medical Equipment unable to start fill or has excessively long fill times?
If your CAIRE Medical Equipment is unable to start filling or has excessively long fill times, it could be due to several reasons. Make sure the transfer line is fully engaged on the Reservoir QDV and properly aligned, applying downward force. Verify that the source pressure is within the 35-50 psi range. Ensure the vent valve is fully open and not blocked. The source tank might be under or over-saturated, so allow LOX to saturate to proper pressure. Check the fill connector and cartridge assembly for damage, ensuring full engagement. Inspect the vent valve for blockages and clean with compressed gas if necessary. Finally, check the reservoir for leaks and repair if needed.
How to troubleshoot increased NER in CAIRE Medical Equipment?
To troubleshoot increased NER, first inspect the saturation pressure of the reservoir, ensuring it has had at least 30 minutes at no flow to saturate properly. Next, perform a leak check on the plumbing and repair any leaks. Ensure that there is no venting from the relief valves; if there is, refer to the corrective actions for excessive venting. Finally, check for a partial or complete loss of vacuum by conducting the NER test and returning the unit to CAIRE, Inc., if necessary.
What to do if my CAIRE Medical Equipment has low flow at the oxygen outlet on all LPM settings?
If you're experiencing low flow at the oxygen outlet on all LPM settings, start by inspecting the nasal cannula for kinks or leaks. Check the saturation pressure of the reservoir, allowing at least 30 minutes at no flow for proper saturation. Perform a leak check on the plumbing and repair any leaks. Clean or replace the flow control valve inlet filter screen if it's dirty. Test the economizer valve and replace it if necessary. Check the warming coils and withdrawal tubes, as well as the flow restrictor, for blockages and replace if needed. Finally, the FCV might be faulty and require replacement.
