6b. To verify the level of liquid oxygen in unit with the
mechanical liquid level gauge:
•
Support the unit, by the fabric strap, directly above
the black contents indicator spring scale chamber.
•
Allow the unit to stabilize (i.e. not bounce up and
down), then read the exposed colored scale for
approximate liquid oxygen contents.
Note:
If the unit is empty, only the red colored band of
the scale will be exposed. If this is the case, the unit
must be filled prior to use.
7. Under certain environmental conditions, with
continuous use, and especially with the portable not
being moved, it may develop excessive frost around
the vaporizer coil and on the case. You may reduce
this frost by tapping the unit and/or wiping any
accumulated frost off the case.
