Transmembrane Pressure (TMP) Test
Following a successful integrity test, with the system still
flushing through a tap, the TMP must again be measured and
recorded on the service tag. To perform this test, follow the
steps in the Transmembrane Pressure Test section.

Battery Replacement
The two AA-sized batteries in the system controller should
be replaced once a year. The batteries are located under
the front cover. Ensure that the settings of the controller are
still appropriate. Refer to Installing the Controller and the
Controller Settings sections.

Maintenance Service Tag
Ensure the maintenance service tag has been completed.

Final Flush by Homeowner
Have the homeowner continue to run a cold water tap for 60
minutes. This is required to meet NSF drinking water standards
and to remove residual chlorine. The homeowner may notice
chlorine taste/smell when a tap is first opened during a day or
two following the sanitization procedure.
