Both inlets should remain 10°F (-12.2°C) or more
below the lowest temperature to which the air
distribution system equipment is exposed. At a

will be affected if bleed flow is not engaged at low flows. (At or below 3 lpm for Low Flow and 15 lpm for High Flow).
* When Heliox tank pressure and oxygen outlet pressures are unbalanced, bleed may need to be engaged at a higher liter flow
to maintain accuracy.
