Regulator and Gauge Panels

The Purge Air Panel contains the pressure regulators and gauges for controlling the purge air and
heater air (see Figure 3-3).
If the analyzer has mechanical regulators and gauges, the Pressure Control Panel will have the
analytical regulators and gauges. (The application determines which specific regulators and gauges
are installed.) If the analyzer has EPC, the Pressure Control Panel has a blank front panel.

Oven Compartment

On the right side of the oven compartment are located the column flow adjustments for setting flows.
These needle valves, located in the oven for thermal stability, allow flows to be set using a
screwdriver through the oven wall without disturbing the thermal integrity of the analysis zone.

PREPARING FOR OPERATION

When the analyzer is first installed or when it is being turned on for the first time after maintenance or
repair, you should verify that all installation and startup checks have been completed (see Section 2
of this manual).
