Remove the system cap using the cap wrench. Insert the
clean internal prelter into the system prelter cavity. Push
down gently to ensure it is seated properly.
Inspect and clean
thimble filter as needed.

Replace the system cap and open the inlet valve. Turn on
a cold water tap to remove any remaining air and residual
chlorine from the system and plumbing. Once the remaining
air is released, leave the tap on for the rest of this procedure.
Transmembrane Pressure (TMP) Test
The TMP test measures the pressure drop across the
membrane. This is the pressure change that the homeowner
will observe as a result of the ltering process. The TMP is
tracked during the life of the system and is used to determine
the condition of the system membrane. As the membrane
fouls, the TMP will increase.

Insert a pressure gauge into each of the inlet and outlet
mini ball valves and open the valves.

With a nearby tap running with a high ow rate, read the
two pressure gauges and subtract the outlet pressure from
the inlet pressure. The resulting value is the TMP. Record the
value on the service tag.
When a pump/pressure tank is in use, use the following inlet
pressures to determine TMP:
Set Points (psi) Inlet Pressure (Psi)
20/40 35
30/50 45
40/60 55

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 rst opened for a day or two
following the cleaning procedure.
