Maintenance
3.8.1
Frequency
It is important to perform scheduled maintenance on equipment and monitoring wells to sustain the
accuracy and longevity of the installation.
The frequency of this maintenance depends on the characteristics of the deployment site, such as the
degree of fouling. Appropriate maintenance schedules should be developed based on site conditions.
It is recommended to check instruments often during the first portion of the deployment to determine
the frequency of maintenance. General maintenance should be performed as often as possible.
3.8.2
Diver
When installed, the Diver does not require any maintenance. The casing can be cleaned with a soft
cloth. Calcium and other deposits can be removed with a commercially available acidic cleaner such
as white vinegar. The flow-through opening can also be rinsed with water and/or a diluted acidic
solution.
Notes:
•
Only use diluted acidic solutions if the Diver has severe build-up of, for example, lime scale
and other cleansers are not effective.
•
Never use any hard brushes, abrasives or sharp objects for cleaning the Diver and always
rinse it properly with clean water after cleaning, particularly near the flow-through openings.
Do not use any powerful jets. This could damage the pressure sensor.
