4. Locate the
3
/
8
" Yellow Tubing. Firmly press one
end into the Holding Tank Shut–Off Valve
and the other end into the tee. (Refer to Fig.
1, page 1.) The fittings will grab the tubing
and seal it in place. Make sure the tubing is
pressed all the way in to create a pressure tight
connection.
Note: If the optional RO Comparator is used,
its location and the location of its test cells
should be determined at this time.
The "In" Cell should be located in the Red
Feed Water Tubing line before the R.O.
System.
The "Out" Cell should be located in the
1

"
Yellow Tubing Line, between the "Out" Port
and the Tee.
F.
Start Up
At time of start up and each time the filters are
changed the system should be sanitized (also see
Operation and Maintenance Sec. V, B.1–4,
page 10).
1. Sanitizing the system. Use a drip pan to aid
clean–up.
NOTE: The system should be sanitized
BEFORE installing the Sediment/Carbon
Prefilter, the Activated Carbon Post Filter or
the R.O. Membrane.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Open the Dispensing Faucet by lifting the
black handle and open the Holding Tank
Shut–Off Valve (the handle should be
parallel with the valve body).
•Remove the plug on the underside of the
manifold labelled “SEDIMENT/CARBON”.
Pour one capful of bleach (this is
approximately 2 tsp. or 10 ml) into one of
the white Housings. Insert a Housing O–ring
into the Housing groove, (press firmly in
place). Engage and firmly tighten the
Housing hand tight only.
•Remove the plugs labelled “MEMBRANE”
and “ACTIVATED CARBON” from the
underside of the manifold. To each of the
remaining white Housings, add one capful of
bleach. Insert a Housing O–ring, engage and
firmly tighten the Housings hand tight only.
•Slowly open the Feed Water Saddle Valve
(turning counter clockwise).
•As soon as the water begins to come out of
the Dispensing Faucet, close the Faucet.
•Let stand for 15 minutes.
NOTE: During this time, check the system
carefully for leaks.
•At the end of 15 minutes, CLOSE the Feed
Water Saddle Valve and open the Dispensing
Faucet.
•Allow the Holding Tank to completely drain,
then remove the Sediment/Carbon Filter
Housing (the farthest of the three from the
In–Out ports), empty, and install the
Sediment/Carbon Prefilter. Firmly tighten
the Housing hand tight only.
•Remove the Activated Carbon Filter
Housing (the closest of the three to the
In–Out ports), empty, and install the
Activated Carbon Post Filter. Firmly tighten
the Housing hand tight only.
2. Installing the R.O. Membrane:
•Remove the R.O. Membrane Housing, (the
middle one), and empty.
•Insert the Membrane up into the manifold.
(The O–rings should be up toward the
manifold.) Check the Housing O–ring for
proper position in its groove, engage and
firmly tighten the Housing hand tight only.
3. Rinsing the system:
•Slowly open the Feed Water Saddle Valve
fully counter clockwise.
•The Holding Tank Valve should be open.
•Check the Air Gap Window on the
Dispensing Faucet to be sure that the drain
water is flowing. (Refer to Figure 2, page 6.)
The R.O. System is now making water.
•Do not open the Faucet for at least 6 hours.
•Do not use the first three full tanks of water.
CAUTION: The R.O. Membrane is shipped
with a preservative in it (0.5% sodium
metabisulfite). This will be rinsed out with
the first water produced. Allow the Holding
Tank to fill (overnight) and discard the first
three full tanks of production. It takes
approximately 6 hours to make a full tank.
When the Faucet is first opened, expect air
and carbon fines (very fine black powder)
from the In–Line and Activated Carbon Post
Filters to be rinsed out. This is normal for the
first tank of water or after the Activated
Carbon Post Filters are changed.
