Air Cleanup Final Preparation; Repairing The Cp Valve; Preparation And Safety - ABB PGC2000 Operation And Service Manual

11. The temperature of the air cleanup assembly can also be monitored from this screen. The time
required to achieve stability is two hours.
12. Press the F1 soft key as necessary to return to the Background screen.

Air Cleanup Final Preparation

1. Restore all utility gases and verify that the pressures and flow rates are correct. These include
oven air, purge air, carrier, burner fuel, and burner air. If the faces of the pressure gauges were
previously marked and the marked location is known to be correct, simply adjust the pressure
regulators until the gauge pointers are aligned with the pressure indicating marks. Refer to the
engineering data package supplied with your analyzer for the correct values.
2. After sufficient air purge time and when authorized by your safety administrator, apply power to
the analyzer.
3. Verify that all Digital Temperature Control setpoint values are correct. Refer to the engineering
data package supplied with your analyzer for the correct values.
4. Allow the temperature controlled zone temperatures to equilibrate.
5. Verify that sample is being introduced to and is sufficiently flowing through the analyzer sample
valve.
6. Perform a minimum of three analyses to verify correct chromatographic response and analysis
reports. Minor adjustments or calibration may be necessary to achieve desired analysis results.
7. Once analyzer operation and performance have been verified, place the analyzer back in service.

REPAIRING THE CP VALVE

This section describes how to replace the CP Valve slider, wedges, and o-rings. The material applies
to both the 40 psig and 60 psig valves (see Figure 8-48).

Preparation and Safety

It is the customer's responsibility to ensure that the area is safe and and hazard-
free, and will remain so the entire time the analyzer is open. This responsibility
includes ensuring adequate ventilation in analyzer shelter and obtaining proper
work permits, etc.
