4. Locate the

" Yellow Tubing. Firmly press
one end into the Holding Tank Shut–Off Valve
and the other end into the tee. (Refer to Fig.
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.
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).
1. Sanitizing the system and installing the
Sediment Prefilter. Use a drip pan to aid
clean–up.
NOTE:
The system should be sanitized
BEFORE installing the Activated Carbon
Prefilter and the RO Membrane.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Open the Dispensing Faucet 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 labeled “SEDIMENT”. Pour one
capful of bleach (this is approximately
2 tsp. or 10 ml) into one of the white
Housings. Unwrap Sediment Prefilter and
install prefilter (O-rings up toward manifold.)
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 labeled “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 Activated Carbon
Prefilter Housing (the one closest to the In/
Out ports), empty, and install the Activated
Carbon Prefilter. 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. The R.O. System is now
making water.
•Do not open the Faucet for at least 8 hours.
•Do not use the first three full tanks of water.
CAUTION:
The R.O. Membrane is shipped
with a preservative in it. To ensure proper
rinsing of the R.O. Membrane it is important
to wait at least 8 hours before emptying
each tank.
When the Faucet is first opened, expect air
and carbon fines (very fine black powder)
from the In–Line Activated Carbon Post
Filter to be rinsed out. This is normal for the
first tank of water or after the In-line filter is
changed.
SECTION V. OPERATION & MAINTENANCE
A. Normal Operation
1. It is normal for the Total Dissolved Solids
(TDS) of the water to be higher than normal
during the first 5 gallons of operation; this is
due to the sanitizing solution and the new
Post Filters. After this water is rinsed to drain,
the removal rate should stabilize at a value of
greater than 75%. The Water Quality Monitor
was designed to measure water quality when
the R.O. system is making water. In order to
assure you are getting an accurate reading,
empty the holding tank, wait 15 minutes until
the system begins making water, and then
test the TDS with the monitor.
