6.1 System Visual Check and Response Procedure
1. Make sure that the signal failure alarm is not in the alarm condition.
2. Check the sample pump operation and function, if applicable
3. Check to see that the homogenizer is running.
4. Check the recorder chart for a normal display, if applicable
5. Make sure that the recorder will not run out of chart or ink.
6.2 Routine Maintenance
The sample lines and components, including the measuring cell within the
analyzer sample module, must be kept free of algae, debris, and undue quantities
of deposited oil to insure accurate analysis.
The interval between cleaning procedures must be determined empirically,
since the duration of time that the system will run without attention is directly
related to the sample’s condition. The frequency of attention is affected by the
following conditions:
1. If the water has been bacteriologically treated, the growth of algae in the
sample passages of the system is a prime consideration. This will dictate
maintenance frequency or corrective action.
2. If undissolved oil is the predominant component of the sample, deposits
in the system become a consideration, particularly if the concentration
exceeds 50 ppm without the homogenizer, otherwise above 200ppm oil.
3. Debris and particulate matter suspended in the sample water will
increase the need for frequent cleaning, since the sample cannot be
filtered.
4. The zero water filter element may become clogged to the point of flow
restriction, at which time it must be replaced or cleaned thoroughlly if
possible with a detergent solvent. Filter element is polypropylane.
