3. Locate the 1/4" (0.6 cm) Black Drain Tubing connected
to the Dispensing Faucet as shown in Figure 1. The end
of the Black Drain Tubing that must be inserted into the
"Drain" port on the manifold will have a "Drain Restrictor"
in it. Remove the black plug from the fitting labeled
"Drain" on the manifold and insert the tubing. Allow the
tubing to relax, then press firmly again to insure proper
seating.
4. Locate the 1/4" (0.6 cm) yellow tubing with the tee
attached to one end as shown in Figure 4. Remove the
yellow plug from the fitting labeled "Out" on the manifold
and insert the tubing.
5. Locate the 3/8" (1 cm) Blue Product Water Tubing
connected to the Dispensing Faucet. Firmly press one
end into the tee. (Refer to Figure 1.) The fittings will
grab the tubing and seal it in place. Make sure that the
tubing is pressed all the way in to create a pressure tight
connection.
NOTE: If you want to pull the tubing out for some reason,
push the ring around the tubing in and pull the tubing out.
6. Hang the Manifold Assembly on the mounting screws and
tighten. Do not over tighten.
7. Remove the wrapping from the In-Line Activated Carbon
Post Filter. Slice 3/8" (1 cm) Blue Polytube where it would
be convenient to install and change the In-Line Filter.
Make a clean straight cut to insure proper connections.
The "Out" port on the In-Line Filter should be toward
the faucet. Firmly press in the tubing. The fitting will
grab the tubing and seal it in place. Make sure that the
tubing is pressed all the way in to create a pressure tight
connection.
Position the Drinking Water Holding Tank and Make the

Final Hose Connections:
1. Check the tank precharge pressure. Make sure that it is
between 5 - 7 PSIG (34 - 48 kPa). If not, use a bicycle hand
pump or other pump to bring the pressure up to the
5 - 7 PSIG (34 - 48 kPa) range.
2. Pull the cap/plug off the top of the tank where the
Tank Shut-Off should go. (Refer to Figure 1)
3. Wrap Teflon tape three times around the 1/4" (0.6 cm) male
†
outlet thread. Wrap in the direction of the threads (clockwise
when looking down on the Holding Tank). The Teflon
act as a thread sealant. Screw on the Holding Tank Shut-Off
Valve.
4. Locate the 3/8" (1 cm) Yellow Tubing. Firmly press one end
into the Holding Tank Shut-Off Valve and the other end into
the tee. (Refer to Figure 1.) The fittings will grab the tubing
and seal it in place. Make sure that the tubing is pressed all
the way in to create a pressure tight connection.
Start Up:
■
Installing the modules and membrane and sanitizing
the holding tank:
1. Open the Dispensing Faucet and close the Holding Tank
Shut-Off Valve (the handle should be perpendicular to the
valve body).
2. Remove the plug on the underside of the manifold labeled
"SEDIMENT/CARBON". Unwrap the Sediment/carbon
Module. Make sure that the module O-ring is pressed
firmly in the groove. Engage and firmly tighten the module
by hand only.
3. Remove the plug labeled "MEMBRANE" from the
underside of the manifold. Trim the top of membrane bag,
exposing the white plastic seal. While holding onto bag,
insert membrane into manifold. (The O-rings must be up
towards the manifold.) Take the remaining housing and
insert housing O-ring into its groove. Engage and firmly
tighten housing by hand only.

4. Remove the plug labeled "ACTIVATED CARBON" from
the underside of the manifold. Unwrap Activated Carbon
Module. Make sure that the module O-ring is firmly
pressed in groove. Engage and firmly tighten the module
by hand only.
5. Close the Holding Tank Valve.
6. Disconnect the yellow product water tubing that runs from
the Holding Tank to the Elbow on top of the Manifold (see
Fig. 1, page 3). Put 50 drops of bleach [this is equal to 1/2
tsp. or 3 ml (0.003 L)] into the tubing and reconnect the
Elbow.
Rinsing the system:
1. Slowly open the Feed Water Valve fully counter clockwise.
2. Open the Holding Tank Valve.
3. Check the Air Gap Window on the Dispensing Faucet to
make sure that the drain water is flowing. The system is
now making water.
4. Do not open the Faucet for at least 8 hours.
5. Do not use the first three full tanks of water.
IMPORTANT: The Membrane is shipped with a preservative in it.
To ensure proper rinsing of the 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 Activated Carbon Module to be
rinsed out. This is normal for the first tank of water or after the
Activated Carbon Module is changed.
OPERATION AND
1. It is normal for the Total Dissolved Solids (TDS) of the water
to be higher than normal during the first 5 gallons (19 L) 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%. Water
pressure affects the production rate and quality.

2. Systems produce drinking water at relatively slow rates; it can
take up to 5 hours or more to fill the Holding Tank. Normal
operation is to let the Holding Tank fill with water and then
draw water as needed. When the pressure in the Holding
Tank falls to a given pressure (as the water is being used) the
ASO Valve will start water production and the system will refill
the Holding Tank. When the Holding Tank is full and no water
is being used, the ASO Valve will automatically shut off the
feed water to conserve water. The more water that is used
(up to the capacity of the system) the better the system will
function. Other uses for the water are flowers, pets and rinsing
glassware.
With each use it is recommended that you run the faucet for
at least 10 seconds prior to using water. This is especially
important if the system has not been used daily. After periods
of non-use, such as a week of vacation, it is better to empty
the Holding Tank and allow the system to produce fresh water
for use. If the system is not used for 3 - 4 weeks or longer, it is
a good idea to re-sanitize the system and to change the
pre-filter and post filters.
