MAINTENANCE
The analyzer does not require any periodic maintenance. However, it may be necessary to
periodically clean the exterior of the analyzer. This may be done with a soft brush, broom or low pressure
water rinse.
DO NOT! use hi-pressure water or a pressure washer to clean the
analyzer. It is likely to be damaged during pressure washing.
The sensor must be kept clean for accurate readings. Normally, the jet clean system will adequately
perform this function.
Model 10 D.O. Sensor: In normal wastewater aeration basins the Model 10 Sensor will not require a
jet clean system; however it is important that the aqueous sample to be measured be allowed to come in
contact with the measuring surface. The sensor should be visually inspected on a monthly basis to insure
that rags and hair have not completely covered the measuring surface. During this time we recommend
rinsing the sensor with a water hose.
In systems with high bio-slim and scaling, the integrated jet clean system is recommended to be used
to prevent the slim and scale from attaching itself to the measuring surface. If wiping the sensing element
is required, use a wet cloth, do not use a brush.
Fouling conditions at wastewater treatment facilities varies considerably from plant to plant.
Experience gained during the first few months of sensor operation will allow the plant operators to
determine their own reasonable schedule of sensor inspection. In no case should this inspection interval
exceed one year.
Model 15/15L TSS Sensor: The sensor must be kept clean for accurate readings. Normally, the jet
clean system will adequately perform this function. However, the sensor should be retrieved and cleaned
manually on a periodic basis to remove the heaviest fouling that may impair the performance of the
sensor. The frequency of this cleaning will vary depending on the application.
