NOTE: One hand should maintain a slight downward
pressure on the unit during filling to assure stability and
proper filling position. Approximately 20-30 seconds
into the filling procedure it is advisable to close and
reopen the vent valve one or more times. This will
break up any ice that may begin to form around the
valve stem and serve to avoid any problems with the
vent valve freezing open.
7. When there is a noticeable change in the sound of venting gas,
followed by the emission of a dense, white vapor around the cover of
the Stationary unit, close the vent valve. Fill time may vary according
to the temperature of the container being filled. Maximum fill time is
approximately 1 ½ minutes.
NOTE: Should for any reason the vent valve fail to close
and the hissing continue, remove the Companion Portable
unit by depressing the portable release button on the
Stationary unit. The Companion Portable unit will stop
venting in a few minutes. Allow the unit to warm until the
vent valve can be closed. A period of 2-3 hours at no flow
may be required to allow the Companion Portable unit to
restore adequate pressure for accurate oxygen flow.
8. Disengage the Companion Portable unit from the Stationary unit by
holding the carrying strap above the unit and depressing the release
button (). Always hold the Companion Portable unit with one hand
when attempting to disengage it. Should the units not disengage
easily, they may have become frozen. DO NOT USE FORCE. Simply
allow a few moments for the frozen parts to warm and disengage
when the ice has melted.
