Replacement arrangements vary by product and operating conditions. Check the specific instructions and operating records first.
Documents to prepare
Record full consumable model designations, compatible equipment, commissioning and maintenance dates, differential pressure, and other available data. When abnormalities occur, check instruments, raw water, and upstream and downstream conditions. Relevant staff should then determine whether adjustment, maintenance, or replacement is needed. This article does not prescribe a universal replacement interval or service life for all consumables.
Using records for the next step
Keep separate dates for raw-water information, equipment information, sampling, and records. Distinguish observations from conclusions about their causes, and mark missing information for review. Retain the confirmation basis and document versions when changing configurations or maintenance arrangements.
