2.0 Take everything out of the box
Examine the contents of the Large and Small Parts Bag against the diagrams below. If any pieces are
missing, check the box, sometimes the pieces can fall out of their bags during the system's journey to
you. Note that there is an extra length of 30' of blue tubing (for running a line to your aquarium sump
tank) plus a float valve not packed in either of the Parts Bags.

3.0 Remove the protective plastic from the prefilters
Inside each of the three prefilter canisters you will find a prefilter with protective plastic for quality as-
surance purposes. Paying close attention to how the filter is sitting inside the prefilter housing, remove
the plastic and then reinsert the prefilter the same way the prefilter was taken out. Do this one at a
time. If by chance you loose track of which filter goes into which prefilter canister, the SED (sedimen-
tary filter) is stage one, the GAC (granular activated carbon filter) is stage two and the CCB (coconut
carbon block filter) is stage three. See pictures below of the three prefilters. The GAC is the only one
of the three prefilters that only goes in one way. The GAC must be placed with the gasket up and the
plastic mesh down.

Sedimentary Filter (SED)
With the prefilters inside each prefilter canister, carefully screw the canisters into place. Try to keep the
prefilters centered as much as possible during this process. Now, using the large canister wrench from
the Large Parts Bag, tighten each of the prefilters with reasonable force in order to seal the filters into
place.

4.0 Inserting the R.O. Membrane
The R.O. Membrane is shipped sealed for
freshness. Remove the R.O. Membrane
Figure 4
from its sealed plastic bag and insert the
membrane firmly into the R.O. Housing
Inserting the R.O.
(see Fig 4). It can only go in one way, the
Membrane in to
end with the two small o-rings is to be
its housing
inserted first.
Please Note: It is extremely important
the two small black "O" rings on the tip
of the membrane seal tightly into place
inside the membrane housing. Please
make sure to insert the membrane as
firmly as possible into the membrane
housing.

TIP
If need be you can use a pair of needle nose pliers or similar tool to grip the white cylinder pro-
truding from the base of the RO Membrane to gain the leverage needed to push the membrane
entirely into its proper position.

When you are certain the Reverse Osmosis
Membrane is firmly in place screw the R.O.

4.1 Inserting the pre-filter elbow adaptors
Using two of the elbow adaptors from the Small

5.0 Preparing the Feed Water to your system
Found under your sink are the water supply shut off valves to your hot and cold water lines. You will
need to SHUT OFF the cold water valve. Run the hot water for 30 seconds and then feel which line un-
der your sink is warm. SHUT OFF the opposite water line – since that will be the cold water line. After
this valve is off, turn on your sink's cold water tap to make sure there is NO cold water flowing from
your kitchen sink faucet. If you shut the valve off correctly, there should be no cold water flowing.
