Troubleshooting & Repair Procedures
RP19 - FCV Test
1) Fill the C1000/T with liquid oxygen. Allow approximately
one hour for the system pressure to stabilize. Verify that the
PRV is venting and that the system pressure is 1.28 – 1.62
bar (18.5 – 23.5 psi).
2) Attach a calibrated flow meter to the oxygen outlet barbed
fitting.
3) At each flow setting, check the flow control valve.
Acceptable flow ranges are given below in Table 9 and 10.
NOTE: Data listed in Table 9 and 10 is based on an operating
pressure range of 1.41-1.66 bar (20.5-24 psi). If the flow meas-
urements are out of specification, check the pressure in the unit. A
combination of high or low pressure and the tolerance of the par-
ticular flow meter you are using can result in inaccurate readings.
