The dewar contains liquid oxygen and it should only be used to fill the portable unit when the user wants to leave the house. If oxygen is needed at home, we recommend the concentrator is used.

Users should be familiar with the component parts of a portable oxygen unit before it is used.

To check the level of liquid oxygen in a dewar, press the liquid level switch for at least two seconds and read the liquid level display. Always reorder when it reaches a quarter full.

If the low battery indicator on the liquid level display lights up when the button is pressed, the user should inform the Baywater Healthcare Healthcare Technician at the next visit.
