Post-Fill Inspection
Perform the following procedure to inspect the Companion 1000/T and determine its
operational status after filling it with liquid oxygen. Correct observed problems before
placing the unit in service.
1. Verify that the Companion 1000/T fill connector poppet is closed and not leaking.
2. Verify that the vent valve is completely closed and not leaking.
3. Connect a test flowmeter to the oxygen outlet connector. Rotate the flow control
through each flow setting. Verify the measured flow increases with each increase in
flow setting.

OPERATING PROCEDURE
To operate the Companion 1000/T, perform the following steps:
1. Check the contents by holding the unit by the end of the carrying strap nearest the
indicator. Verify that there is enough liquid oxygen to meet anticipated needs.
2. Attach the oxygen cannula tube to the oxygen outlet connector. Adjust the cannula
to comfortably fit the face.
3. Turn the flow control knob to the prescribed oxygen flow rate.
The pressure in the Companion 1000/T may be slightly lower than normal for
up to 20 minutes after filling the unit. This may cause actual oxygen flows to be
slightly lower than normal.
