*Chlorine Breakthrough greater than 0.1 ppm occurs in
concentrate from the yellow line.
Materials Required:
10 micron Carbon Block Filter (CF-10-10)
Procedure:
1. Turn off water supply to system.
2. Unscrew the hex-nut from the carbon pre-filter input
fitting. See photo on page 7.

3. Unscrew the hex-nut from the output port on the carbon
pre-filter housing. This is the black line that runs between
the carbon pre-filter and the RO membrane housing.
4. Separate the RO membrane assembly from the holding
clips.
5. Unscrew the input and output elbow-fittings from the
carbon pre-filter. Remove the old teflon tape from the
threads of the fittings and apply new teflon tape.
6. Screw the teflon-taped elbow-fittings into the pre-filter.
7. Re-attach the black tubing with the attached hex-nut to
the carbon pre-filter input and attach the short black
tubing between the membrane feed and the output of
the carbon filter.
8. Turn on system water supply and check for leaks.
Note: Position the arrow on the pre-filter towards the short
black tubing attached to the RO membrane.
*Collect a 10 ml sample of the concentrate from the yellow
tubing and test the chlorine concentration using test kit
TK-CL-25. If the chlorine concentration is above 0.1 ppm,
replace the carbon pre-filter.

Place the flow restrictor in a safe location where it will not
be accidentally crushed or damaged.
Re-insert the blue, black and yellow tubing into the push
fittings of their respective ports on your replacement
encapsulated membrane, as described in the Removal,
Adjustment, and Replacement section on page 7,
line 6, a-c. See photo on page 7. Snap the membrane
assembly back into its holding clips.
Note: The flow restrictor assembly should remain
uninstalled at this point in the process.
8. Reconnect the short black tube with the attached hex-nut
to the output port on the carbon pre-filter housing.
Put the yellow concentrate tubing in the drain and turn
on the system water supply. Allow the system to flush for
5 minutes to remove any loose particles.
System Maintenance
RO Membrane Replacement
Maintenance Regime:
As needed. Refer to the procedure for
testing membrane quality on page 12.
Materials Required:
Replacement Encapsulated TFC Membrane
Procedure:
1. Turn off water supply to the system.
2. Mark, or otherwise note, the locations of the yellow, blue,
and black tubing connected to the encapsulated
membrane. See photo on page 7.
3. Unscrew the hex-nut from the output port on the carbon
pre-filter housing. This is the black line that runs between
the carbon pre-filter and the RO membrane housing.
4. Separate the RO membrane assembly from the
holding clips.
5. Remove the yellow, blue, and black tubing from the
encapsulated membrane by depressing their gray push-
fittings with your thumbnail and pulling the tubing from
the fittings.
6. Remove the flow restrictor assembly from the end of the
yellow tubing as described in the Removal, Adjustment,
and Replacement of Flow Restrictor Assembly section on
page 6, line 3.
