Step 3. Removing the old R.O. Membrane and inserting the new R.O. Membrane
(Fig. 30)
Please note: The R.O. Membrane needs to be inserted as firm-
ly as possible to ensure a proper seal is formed. For the R.O.
Membrane to function properly it is extremely important for
the two small “O” rings on the tip of the R.O. Membrane to seal
properly inside the R.O. Membrane housing. To gain added
leverage you can use a pair of needle nose pliers (or the like)
to grab hold of the 1 inch white cylinder protruding from the
base of the R.O. Membrane to push in and twist slightly. You
will notice the membrane slip further into its housing forming
the necessary seal described.
Next, screw the R.O. Membrane housing Cap back into place
using the small canister wrench and reinsert the white tubing
(Fig. 31).
If you are done replacing filters for now, you can re-pressurize your system by turning on the feed
water line via the Manual Shut-Off Valve and turning the tank top valve back on. Please note: Your
new R.O. Membrane comes saturated with food grade preservative so that it stays fresh and does not
dry out and therefore it is wise to flush 2 tanks of water before drinking the water from the new mem-
brane. Allow the tank to fill and empty this down the drain via the faucet. Allow the tank to fill one
more time and drain this as well. You can now enjoy your purified water once more. This concludes the
steps to change the Reverse Osmosis Membrane of your system. Remember to mark on your calendar
when to change these again and check for any other filters that may need changing at this time in the
Home II Filter Change Schedule starting on page 17.

Removing The Old Membrane: You will now be able to
see the Reverse Osmosis Membrane inside the R.O.
Membrane Housing. The membrane can swell inside its
housing making it difficult to remove by hand. Use a pair
of needle nose pliers (or the like) to grab hold of the
1 inch white cylinder protruding from the base of the
membrane and pull out the old R.O. Membrane.

Inserting the new R.O. Membrane: Your R.O.
Membrane comes sealed for freshness in a clear
protective plastic. Remove your new membrane
from its protective plastic. Insert your new R.O.
Membrane into the R.O. Membrane housing of your
system. The end of the R.O. Membrane that has the
two small “O” rings gets inserted first.

With the new membrane in place it is important to verify the ppm (parts per million) reduction
rate of the purified water being produced by the R.O. Membrane. To do this you will need to use
your TDS Meter.
Please note: If you do not have a TDS Meter we highly recommend you acquire one as it is the
only way to verify the purity of the water the system is producing.
Follow the instructions in Figure 26 to test your purified water. It is important to note that your
new R.O. Membrane comes saturated with food grade preservative so that it stays fresh and does
not dry out and therefore it may take 10-15 minutes of purified (permeate) water flowing out of
the blue tube to show the ppm reduction rates described in Fig. 26 and just after Fig. 26. If, after 15
minutes, you do not see the reductions rates as descibed it simply means your R.O. Membrane is not
seated properly inside the R.O. Membrane housing and as such you will need to “re-seat” the R.O.
Membrane. To do this simply follow the directions depicted above (Fig. 29 - 31) to remove and re-
insert the same R.O. Membrane. Then re-test the permeate water for ppm reduction percentages.
