Feed and Drain Connections
Feed Connecon
1. Locate and turn o the angle stop valve on the cold water line feeding the sink. This valve will
usually be located under the sink on the pipe coming out of the wall.
2. When the angle stop valve is closed, relieve pressure in the line by momentarily opening the
cold water tap on the sink.
3. Disconnect the cold water faucet feed line at the angle stop valve.
4. Install the feed valve assembly into the angle stop. (Fig. 1)
5. Firmly press the green 1/4” tubing into the 1/4" connector on the feed valve assembly.
6. Connect the cold water faucet feed line into the feed valve assembly.
7. Make sure the small shut-o valve on the feed valve assembly is closed. Turn on the feed water
connecon valve. Check for leaks.
7. Aach the small feed valve warning tag from the parts bag to the feed valve.
8. Aach the Shuto Warning label to the system so that it is directly visible. Fill out the Date of
Installaon label and aach to the side of the system.
Drain Connecon
1. You will need an electric drill with a 3/8” bit and a screwdriver for this poron of the installa-
on.
2. Obtain the drain saddle assembly, two 1 ½” bolts, two 3/8” hex nuts, and the small adhesive
foam pad from the small parts bag (Fig. 2).
3. Place the adhesive foam pad on the inside of the drain saddle front, aligning the holes.
4. Posion the drain saddle on the drain pipe under the sink between the “P” trap and the sink
connecon. Orient the drain saddle so that the opening is on the side of the drain pipe.
5. Using the bolts and hex nuts, hand ghten the saddle bracket evenly unl the saddle grips the
pipe snugly. Use a Phillips screwdriver to fully ghten the bolts. Do not overghten.
6. If necessary, remove the drain saddle connector nut from the opening of the drain saddle.
Using the connector opening in the side of the drain saddle as a guide, drill a 3/8" hole through
the wall of the drain pipe.
7. Extend the drain tubing from the RO dispensing faucet to the drain saddle and measure for
length. The tubing must be routed so that water can run downhill for the enre length of the
tubing from the faucet. Avoid low spots or loops. Cut the tubing shorter, if necessary.
8. Insert the drain tube from the R.O. dispensing faucet through the drain saddle connector nut.
Tighten the connector nut onto the drain saddle.

Note: This faucet requires a 1¼" opening in the sink or countertop.
1. Locate the faucet parts bag and arrange the parts on the
countertop in the sequence shown.
2. The last part in the sequence, the quick connect adapter (6), will
be found in the smaller parts bag.
3. Pull the white, yellow and blue tubing up through the faucet hole
in the sink.
4. Insert polished faucet base and rubber seal onto base of
faucet.
5. Push the 1/4” yellow drain tubing onto the 1/4” barb ng. This
tube must be of sucient length to reach the yellow drain connecon
on the manifold.
6. Push the white 3/8” tubing onto the larger 3/8” barbed ng,
being sure you have enough tubing to reach the drain saddle.
7. Slide white plasc spacer open-end-up onto the threaded faucet
stem (2). Note: This spacer may be omied it faucet is installed in a
granite countertop (or countertop with similar thickness).
8. Thread the 3/8" washer (3), serrated washer (4) and mounng
lock nut (5) onto the threaded stem.
9. Thread faucet quick-connect adapter (6) on to threads of faucet
stem. NOTE: This connecon should be hand-ghtened only. Push
one end of 3/8" blue tubing into 3/8" connecon.
10. Insert tubing and faucet assembly down through the sink hole.
11. Posion the faucet to the desired handle orientaon. Slip the
sloed washer (1) between the white plasc spacer and the sink.
Securely ghten the mounng nut.
12. Connect the white 3/8” tubing to the drain saddle assembly using
the drain connector nut supplied. This tubing should follow as direct
a path as possible; long runs, looping or deep sags will restrict normal
brine ow to the drain. Save the
unused poron of the tubing for the installaon of the storage tank.
10. Firmly insert spout assembly into the top hole of faucet body
(approximately 1/4"). You may swivel the faucet le or right.

Determine the most praccal under-the-sink locaon for placement of the Sierra manifold unit and the companion reservoir
tank. Ensure that the specic locaon allows adequate access to the manifold unit for cartridge re placement and to the
tank for tank- valve operaon.
1. Place the manifold and tank in the selected locaons. If desired, the #6 self tapping screws may be used to secure the
manifold unit in posion by means of the top rear and boom lip mounng holes.
2. Take the unused poron of the 3/8" white tubing and insert one end rmly into the 3/8" (largest) connector on the top of
the manifold unit.
3. Extend the 3/8" white tubing from the manifold unit to the tank valve. Leave enough slack in the tubing to allow the unit
to be removed from the installed locaon for servicing. Cut o the excess and insert the 3/8" tube into the quick-connect
tank valve ng unl it is fully engaged.
4. Extend the 1/4" yellow tubing from the faucet unit to the manifold. Leave enough slack in the tubing to allow the unit to
be removed from the installed locaon for servicing. Cut o the excess and rmly insert the tubing into the corresponding
yellow drain connecon located on the manifold.
5. Extend the 3/8" blue tubing from the faucet unit to the manifold. Leave enough slack in the tubing to allow the unit to be
removed from the installed locaon for servicing. Cut o the excess and rmly insert the tubing into the corresponding blue
product water connecon located on the manifold.
6. Extend the green tubing from the feed connector valve to the manifold. Leave enough slack in the tubing to allow the unit
to be removed from the installed locaon for servicing. Cut o the excess and rmly insert the tubing into the correspond-
ing green feed connecon located on the manifold.
7. Obtain the Shuto Warning label and ax it to the manifold unit so that it is directly visible. The Sierra system is now con-
nected and ready for inial test and preparaon.
TUBING HINTS: Use a sharp knife or tubing cuer to cut the tubing squarely, being sure to remove all burrs. Then insert the
tubing rmly unl it stops. To remove the tubing, push against the collet while pulling on the tubing.

System Acvaon
1. Check all tubing connecons to ensure they are rmly seated. CHECK TO SEE THAT THE CARTRIDGE RETAINER CLIPS
AND LOCKS ARE PROPERLY ENGAGED. Failure to keep the retaining clips in place could result in accidental leaks and ood-
ing.
2. Open the dispensing faucet at the sink. Close the tank shut-o valve.
3. Open the feed water valve to the system. Observe all tubing and connecons for several minutes to detect any leaks.
In approximately 5 minutes, (assuming normal feed water pressure) the dispensing faucet should begin dripping.
4. Place a pan or other tempo rary water basin near the drain 'P' trap. Loosen the connector nut holding the 3/8" tube
in the drain saddle connec tor. Pull the tube out of the connector and use the pan to catch any water that may spill. Brine
water should be owing from the tube. Reconnect the tube to the drain saddle and hand-ght en the connector nut.
5. Allow the faucet to run for up to 15 minutes, then close the faucet.
6. Check connecons for leaks.
7. Open the tank shut-o valve.
Inial Flushing Procedure
1. Before the system can be used for drinking water producon it must be adequately ushed. Each reservoir tank is
dosed with a small amount of powdered chlorinated sanizer before shipment in order to ensure tank internal cleanliness.
Also, the carbon lter cartridges will release a small amount of carbon nes during the rst tankful of ow. This ushing
procedure will allow any sanizer or carbon nes to pass from the system.
2. Inial tank lling will take approximately two and one half hours (based on average feed pressure). When the tank is
full, the water pressure will have risen to the point where the automac shut-o valve inside the unit will stop the feed ow
through the system. Actuaon of the automac shut-o valve can be determined by checking for a lack of brine ow to the
drain saddle. When the tank has lled for the rst me, it should be le undisturbed for at least 8 hours to ensure proper
sanizaon.
3. Aer 8 hours have elapsed, open the dispensing faucet fully and allow the product water to run out to drain at maxi-
mum ow. The inial discharge will be dark with the bulk of the carbon parcle wash out. There may also be the scent of
chlorinated water from the sanizing agent. When the ow has diminished to a fast drip or small stream, close the dispens-
ing faucet.
4. Fill and ush the tank at least three mes prior to use. If necessary, repeat unl the chlorinaon scent has disappeared.
It is important that the ush be done at maximum ow (e.g. the tank must be full) to assist in rapid wash out. Aer this
ushing procedure the system is ready for normal use.

Checklist
1. System is located where it will not be subject to physical impacts or rough contact by heavy objects.
2. Feed water pressure to the unit is no less than 40 psi and no greater than 80 PSI.
3. Ensure the plasc retainer clips that holds the cartridges in place are fully engaged and locked in place. The slide locks
must snap into place in the slots. If the clip does not snap easily into place through the slots it means the cartridge is not fully
inserted into the connectors. Press top or boom of cartridge to engage connectors unl it snaps into place properly.
4. All tubing connecons, especially push-in quick connecons, are fully inserted.
5. Tubing connected between the faucet and the drain saddle ng (the ng aached to the sink drain pipe) runs "down-
hill" to the drain. There should be no loops or places where water would not ow out to the drain.
6. Feed water valve is open.
7. Within one to two hours aer inial applicaon of water pressure, check again for leaks especially at the tank, faucet
tubing and connectors. These parts will not see full pressure unl approximately 2 hours aer the system is acvated.
8. Flush three tankfuls of product water to drain. If a chlorine scent persists, repeat ushing procedure.

9Cartridge Replacement
1. Close the feed water shut-o valve.
2. Close the tank shut-o valve.
3. Open the dispensing faucet to relieve system pressure. Close dispensing faucet when ow has stopped.
4. Pull the unit from the installed locaon.
5. Remove the retaining clip from the front of the unit. Pull the cartridge o the unit evenly at top and boom. Dispose
of used cartridge.
6. Install the new cartridge, rocking gently from side to side as necessary unl the cartridge tubes are properly engaged in
the unit connectors. Install the retaining clip, ensuring the slide locks snap into place in the slots. If the clip does not snap
easily into place through the slots it means the cartridge is not fully inserted into the connectors. Press the top or boom of
the cartridge to engage the connector so that it snaps fully into place.
7. Repeat Steps 5 and 6 for each cartridge to be replaced.
8. Turn on feed water shut-o valve and open dispensing faucet.
9. Close dispensing faucet aer water starts running.
10. Observe system for any leaks, especially at newly re placed cartridge.
11. Open the tank shut-o valve.
12. If replaced cartridge was a post carbon or a membrane lter, the system should be ushed at least once as described in
the previous secon - Acvaon and Flushing.
