into the Holding Tank Shut–Off Valve fit-
ting. Make sure the tubing is pressed in all
the way past the O–ring. The fitting will
grab the tubing and seal it in place.
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
Blue Product Water Tubing Line, between
the "Out" Port and the Dispensing Faucet.
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 and installing the
Sediment Prefilter. Use a drip pan to aid
clean–up.
NOTE:
The system should be sanitized
BEFORE installing the Activated Carbon
Post Filter or the R.O. Membrane.
• Use a good quality unscented 5 % 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”. Remove
the protective wrapping from the
Sediment Prefilter. Pour one capful of
bleach (this is approximately 2 tsp. or 10
ml) into one of the white Housings. Install
the Sediment Prefilter. (Install ONLY the
Sediment Prefilter at this time.)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 “MEM-
BRANE” 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 tight-
en 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 sys-
tem 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
Filter Housing (the closest of the three to
the
In–Out Ports), empty, and install the
Activated Carbon Post Filter. Firmly tight-
en 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 mani-
fold. (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 8
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 produc-
tion. It takes approximately 8 hours to
make a full tank.
When the Faucet is first opened, expect
air and carbon fines (very fine black pow-
der) from the Activated Carbon Post
