Maintenance & Troubleshooting
After the analyzer has been put into operation and calibration has been accomplished, routine inspection will be required for normal operation.
5.1 Flowmeter and Humidifier
The flowmeter and humidifier column must be checked daily to insure proper flow, and corrected as necessary. Refer to Section 2.2: Humidifier and 4.4: Throttle Valve.
5.2 Cell Electrolyte Level
The level of electrolyte in the cell must be checked daily and adjusted as necessary. Refer to Section 4.2.3: Cell Installation. The proper level for the electrolyte is when the bottom edge of the sensor screen is wetted but not immersed. Approximately 3/32 " of the silver electrode should extend into the pool of electrolyte.
5.3 Reservoir
The water level in the reservoir should be checked at least every two weeks. Follow this procedure:
a)Remove the cap from the filler spout.
b)Obtain a clean glass tube about 4 to 5 inches long and about ¼ " outer diameter.
c)Lower the tube into the tank through the filler spout until it touches bottom.
d)Place a finger over the end of the tube, and withdraw the tube from the tank. The height of water in the tube is the height of the water level in the tank.
e)If the water level in the reservoir is below 1 ", add a quart of distilled water.
f)Replace the filler spout cap securely after verifying that the O- ring seal is in good condition.
