Figure 26. Location of Cylinder Pressure LEDsIf the cylinder pressure LEDs remain dark, it means
that the cylinder pressure is inadequate or that the
cylinders are not connected properly.
5. Close the cylinder valves.
Table 2. Recommended Cylinder Gas PressuresCylinders attached to the hanger yokes must contain
gas at the recommended pressures shown in
Table 2. (Indicated pressures are for E-size cylinders
at 70°F/21°C.) Cylinders measuring less than the
minimum recommended pressure (PSI - MIN) should
be replaced with new, full cylinders.
Caution when handling O2 cylinders
Note: Follow the Instructions for Use included with
the pressure regulator.
WARNING!
Risk of gas supply failure
If the valves remain open when connected to the
pipeline gas supply, gas may be withdrawn from
the backup gas cylinders.
Close backup gas cylinder valves whenever
pipeline gas supply is sufficient.
