Why is there a hissing sound coming from my CAIRE Oxygen Equipment Liberator?
During normal operation of the CAIRE Oxygen Equipment Liberator, the unit's primary relief valve will open from time to time to relieve excess pressure, especially soon after filling. If hissing is persistent or abnormal, this could indicate excess pressure being vented off or a leak in the system.
Why is my CAIRE Medical Equipment venting excessively from relief valves (hissing sound)?
Excessive venting, indicated by a hissing sound, could be due to several reasons. The saturation pressure might be too high, so inspect it and allow at least 30 minutes at no flow for proper saturation. The relief valve might be frozen open, in which case you should allow the portable unit to warm and thaw before attempting to refill it. A faulty relief valve could also be the cause, requiring a 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 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.
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 liquid oxygen is evacuating from the blue QDV on my CAIRE Oxygen Equipment?

What to do if liquid oxygen evacuates from the blue QDV on my CAIRE Liberator G4?
If liquid oxygen is evacuating from the blue QDV of your CAIRE Oxygen Equipment, the QDV may have frozen open. Open windows if possible and evacuate the area immediately. To prevent this, wipe the QDV with a dry, lint-free cloth before and after filling your portable.
Why is there frosting on the tank or side of my CAIRE Liberator Oxygen Equipment?
If there is frosting on the tank or side of your CAIRE Liberator, this is abnormal; contact your service provider for assistance.
What to do if there is condensation or water pooling up on the floor from my CAIRE Liberator G4 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.
How to fix liquid leaks from coupled QDVs during fill of CAIRE Medical Equipment?
