7. When you notice a change in the sound of venting gas followed by a
dense, white vapor coming from the Stationary cover, close the vent
valve. Fill times may vary according to the temperature of the
container being filled.
Note: If the vent valve fails to close and the hissing
continues, remove the Portable unit by depressing the
Portable release button (Figure 12 and Figure 13) on the
Stationary unit. The Portable will stop venting in a few
minutes. Allow the unit to warm until you can close the vent
valve. The Portable may require two to three hours at no
flow to restore adequate pressure for accurate oxygen flow.
8. Disengage the Portable from the Stationary unit by holding the
carrying strap above the unit and depressing the release button
(Figure 13). Always hold the Portable unit with at least one hand
when attempting to disengage it.
Figure 13: Disengaging the Portable Unit
If the units will not disengage easily, they may have become frozen.
DO NOT USE FORCE.
Simply allow a few moments for the frozen
parts to warm, then disengage the Portable when the ice has melted.
