My respironics Everflo oxygen generator whistles at the end of every other pump cycle . It’s the same whether flow rate is 1lpm or or 3lpm or 5 lpm.
I’m a retired test engineer and have checked the components and hoses with the back cover off and can’t isolate the source.
Any direction will be appreciated.

I have an Everflo with a system malfunction. Red light on alarm on full. This unit is relatively new. All the filters have been changed. Is there a common problem with these units?

I need the service tool to identify what is happening, a red fault light comes on after 10 minutes, but the concentration rate is at 96%@5LPM and pressure between 17~25 PSI, a 4-way valve is new and apparently not there is a leak.
