Operations

4.1Filling the Reservoir

The reservoir is located on the right side of the analyzer case.

1)Insure that the cap on the drain spout is securely tightened.

2)Remove cap from fill port on top of reservoir.

3)Pour distilled water into reservoir until it is half full (about one quart). The water will automatically flow into the humidifier column.

4)Replace cap on fill port and securely tighten. A missing or loose cap will permit the sample to vent into the analyzer case.

4.2Detector Cell

The cell is located in the heated compartment on the left side of the analyzer case, as shown in Figure 4-1. To open the compartment, unscrew the captive knurled knobs at the top and bottom of the compartment and remove the plastic window.

4.2.1 Cell Packaging

The cell is packaged separately from the analyzer. It is filled with distilled water to prevent oxidation of the electrodes from exposure to the atmosphere. The cell should be left filled with the distilled water until the analyzer is installed and ready for operation. The cell should not be exposed to the atmosphere for any prolonged duration.

4.2.2 Electrolyte

The cell electrolyte is Teledyne Type A, used in applications where there is a complete absence of acidic anhydrides (CO2, SO2) in the sample gas. Type A electrolyte is a 10% solution (w/v) of reagent-grade potassium hydroxide (KOH) in distilled water.
