GENERAL
MF cleaning is performed when indicated by an MF Trans-Membrane Pressure High alarm. TMP is
typically 3 to 5 psi at 50 to 60 gpm MF Feed Flow after cleaning. The alarm setting and the maximum
allowable pressure (psi) are dependent on the water temperature (0F) as indicated in the chart below.

exceed the maximum pressure listed for various temperatures in the chart above. Clean sooner if
required.
