5.1 INITIAL FLOW RATE SETUP
Locatethereferenceairowmeters,andadjusttheowadjustmentknobsasoutlinedbelow:
Reference Air: 0.8 LPM

The maximum working pressure of the MC1 and AC1 unit is 35 psi. Excessive pressure can damage the
Zirconia cell of the ZR22G Oxygen Probe.

If reference air is used during calibration, the reference air must be left ON after calibration.
5.3 CHECKING FOR LEAKS
1. PositionthevalvetoSPAN
2. Applyaleakdetectionsprayonallcompressionttingsandbendsofthecallinetubingfortheprobe,theMC1
gas inlets/outlets, and the probe inlets for CAL and REF gas.
3. Inspect the full length of the CAL and REF lines for leaks.
4. Repair leaks as necessary, and within applicable guidelines
5. After repairing the leaking areas, repeat the inspection instructions above for the affected areas.
6. Uponcompletion,returnthevalvetotheOFFposition,andsettheReferenceandCalgasowratesto0.8LPM
