Record the gauge readings on the oxygen generator at least twice a month on the log sheets included with your system.
If you notice any unusual or significant changes from the previous readings (for example, a compressor has been reading 20-22 psi and you observe it is only reading 5 psi) immediately call TECH SUPPORT.
Remember: The unit must be running for the gauges to be active. If the unit is not running, turn on the red bypass switch. Wait 2 minutes before reading the gauges. THEN TURN THE RED BYPASS SWITCH OFF!
The two small filters on each compressor should be changed at least four times a year. (We automatically send these filters to you).
When you receive the new filters, simply twist the black filter caps to the left and lift the caps off the filter base. Change the filter inside and replace the filter cap by gently pushing down and turning until the cap locks in place. Contact Tech Support if you need help or more filters.
