Helpful Tips Before You Begin
Prior to installation, we’ve listed out a few helpful tips to help the install go smoothly.
TIP #1: The AustinSprings RO features Quick-Connect fittings
To Connect:
1. The system comes with 5 tubes (red, 2 black, yellow and blue); confirm that each tube has a
flat end if not…
2. Create a clean, square edge for each tubing by cutting the end with a utility knife.
3. Measure 1
–
2"from the end and mark with a permanent marker.
4. Remove the blue Lock Clip and insert the tubing into the Lock Sleeve, until the mark nearly
disappears. Return the Lock Clip.
To Disconnect:
1. Remove the blue Lock Clip.
2. Gently push the Lock Sleeve down with two fingers to where the blue Lock Clip was removed.
3. Pull to remove.

TIP #2: Compression fittings easily create a water-tight seal
1. Slide the Brass Nut and then the small White Collar onto the end of tubing.
2. Push the White Insert into the open end of tubing.
3. Slide the collar back over the inserted end of the Insert.
4. Hold the collar and Insert into the threaded faucet base opening.
5. While holding the collar and insert onto the base, screw on the nut and tighten.
This creates a water-tight seal and hardens the tubing.
TIP #3: The Faucet Hole
The AustinSprings faucet may be mounted on the sink using an existing hole, oen for a soap
dispenser or sprayer; or, by drilling a hole at least 7
–
8"in diameter.
Drilling holes into solid and stone surfaces should be
performed by a qualified and certified installer.
TIP #4: Converting the Water Feed Adapter to a dierent size.

Installation Steps
Step 1: Connect the Water Feed Adapter
The Water Feed Adapter can convert to larger and smaller pipe threads. (Tip #4)
1 Turn o the cold-water supply by locating the valve
under the sink. Confirm it is o by turning the sink faucet
onto cold. No water should be running through.
2 Disconnect the faucet connector pipe from the cold-
water supply. Place a towel underneath to catch any
drips.
3 Attach the Water Feed Adapter to the cold water supply.
Re-connect the faucet connector pipe to the Water Feed
Adapter.
4 Connect the 1
–
4"RED tubing to Water Feed Adapter. (See Tip #1)
Step 3: Install Drain Saddle
1 Choose a convenient spot for installing the drain saddle and tubing. Installing on a horizontal
portion of the drain pipe will minimize dripping noise.
2 Drill a 1
–
4"hole. Paste the black sticky pad over it ensuring the holes align.
3 Cut the end of the 3
–
8"Black tubing from the faucet drain output to the desired length. Mount
the drain saddle by tightening the two screws and hex nuts. Ensure that the hole in the drain
saddle is aligned with the hole that was drilled in the drain pipe.
4 Connect the 3
–
8"BLACK tubing to the drain saddle. (See tip #1)
Step 4: Install the Vertical Filters — Stages 3, 2 and 1
1 Inspect filter housing. O-ring should be in the groove at the top.
*Optional: Use Food-grade silicon jelly on O-ring for a better seal.
2 Unwrap the filter cartridges; follow the color-coded stickers on the
packaging.
3 Place each filter cartridge into its housing. Make sure the center hole of
each filter is aligned onto the raised ring at the bottom of each housing.
4 Screw each filter housing (with loaded cartridges) into the RO manifold.
Ensure each cartridge is aligned to each of the center posts of the
RO manifold. Twist clockwise by hand. Use housing wrench to tighten
about 1
–
4turn. Overtightening may cause damage and leaks.
5 Repeat these steps for each cartridge. NOTE: the second stage must go
in a certain direction — the end with the rubber washer faces up.
Step 5: Install Tank Shut-o Valve
1 Use Teflon tape to wrap metal thread at
the top of the tank. Wrap clockwise 10-
15 turns.
2 Screw on Tank Shut-O Valve and
tighten up by hand. Do not over tighten.
3 Connect the YELLOW tubing to the
Quick-Fitting of Tank Shut-O Valve.
Step 2: Install Drinking Water Faucet
1 Using the existing 7
–
8"hole or aer having one drilled,
clean and dry the area.
2 Slide the faucet cu and o-ring over the faucet base
threads.
3 Insert the faucet, threaded side down, into the hole.
4 From under the sink, slide the split washer, spacer,
and lock washer on and firmly secure it with the lock
nut.
5 Insert the black 1
–
4"tubing onto the drain input nipple.
6 Insert the black 3
–
8"tubing onto the drain output
nipple.
7 Assemble the compression fitting (See Tip #2)
8 Insert the compression fitting into the threaded
end of faucet, tighten nut. Once it is tightly in place,
gently pull tubing to confirm it is secure.

Step 6: Install Reverse Osmosis Membrane
1 Disconnect the white 1
–
4"tubing from the Inlet quick-fitting on the membrane housing cap (see
Tip #1). Unscrew the cap. (The small housing wrench may be needed to loosen the cap.)
2 Remove the membrane from its sealed bag. Follow the flow direction sign on the membrane,
and firmly push into the housing. Insert the small end (two black O-rings) head first until the
large end is even with the housing opening.
3 Before screwing the housing cap back on, check that the O-ring is fitted evenly on the
membrane housing (cap does NOT have O-ring). Use the small housing wrench to tighten about a
half-turn. Do not overtighten. Do not reconnect tubing at this point.
Step 8: System Start Up
1 Organize tubing and check each for kinks. Turn Tank Shut-O Valve to “OFF”. Have a towel
ready to catch leaks.
2 Keep the tubing to the RO membrane inlet unattached (Step 6), flush the first three stages into
a bucket until the water runs clear. Then re-connect the tubing to the RO membrane. (Tip #1).
3 Turn on the Feed Water Adapter valve. Then, slowly turn on the Cold Water Supply Valve and
check for leaks. Leaks can result when: tubing is not fully inserted, the 0-ring is not secure,
Housing/Cap are not tightened properly.
4 Aer any leaks have been resolved, turn on the RO Drinking Faucet.
5 RO water should start dripping within 5 minutes. Let run for 10 minutes, allowing the system
(except tank) to flush. Water will be dark due to loose carbon from filters, it will turn clear.
6 Turn o the RO Drinking Faucet. Turn Tank Shut-O Valve to “ON”. Allow tank to fill. It should
take between 11
–
2to 3 hrs (longer for colder weather).
7 When tank is full, turn on RO Drinking Faucet to flush water from tank. DO NOT use first tank
of water. Water will surge from faucet. When it slows to a trickle, the tank is empty and can be
refilled for use.
8 For the first two weeks following installation,
check for leaks daily. *Optional: Place a bucket
under system or use the included Water
Detector Alarm in case of leaks.
9 Test RO water periodically to verify eective
reduction of total dissolved solids (TDS). If the
TDS of source water is 100ppm, RO water
should be less than 10ppm.
Congratulations!
Now that your system is installed
enjoy clean healthy water right from your tap.

A TDS meter
is a handheld device that
measures Total Dissolved Solids. TDS
are expressed in units of mg per unit volume
of water (mg/L), or referred to as parts per
million (PPM). With a TDS meter, you can easily
compare the quality of RO water
with your original
source water.
Your system is equipped
with an Automatic Shut-O
Valve allowing your system to turn o
the water supply to the RO system, using
pressure from the pure water side of the
system. It saves water, extends filter life,
and improves the performance of
your unit.

RO SYSTEM MAINTENANCE
This RO system is designed with ease of use and low maintenance in mind. If you change the filter
cartridges as suggested below, and check TDS level periodically, the system will work properly for
many years. For filter replacements, visit AustinSprings.com
Stages 1, 2 & 3: Replace every 6 months, or sooner if water flow gets slow.
The actual performance of the filters depends on your water. We recommend changing every six
months. Sooner if you are on well water or you notice heavy sediments and particles in through the
clear housing (stage 1).
How to replace stage 1, 2 & 3 filter cartridges
1. Turn o water supply and tank valves. Open RO faucet to depressurize. Place a towel or bucket
under the unit to catch any spills.
2. Remove system from under sink location. If the system is attached to the wall, it may be
feasible to remove the filter housing in place. If not, pull the system out and gently place it on
a towel. Use caution to keep the tubing connections in place.
3. Twist filter housing counter-clockwise to unscrew it. Use the large housing wrench if
necessary.
4. Refer to Installation Step 4 (p7) to install replacement filter and reattach as instructed.
5. Flush the system.
Stage 4: Replace every 2 – 3 years or sooner if TDS level starts increasing.
Check the TDS level at least once a month to monitor the system performance. The rejection rate
should be above 90% (NSF/ANSI STANDARD 58 for RO water filter). Reverse osmosis membrane usually
last 2 – 3 years, depending on the source water quality and the replacement schedule of the three
pre-filters. To ensure system performance and water purity, filter cartridges must be replaced on
schedule.
How to replace the reverse osmosis membrane
1. Turn o water supply and tank valves. then open RO faucet to depressurize. Place a towel or
bucket under the unit to catch any spills.
2. Remove the tubing from the inlet fitting on the membrane housing cap. Unscrew the housing
cap (counter-clockwise looking from inlet). Use a housing wrench if needed.
3. Pull out the old membrane. Use screwdriver or pliers to apply leverage if necessary.
4. Clean the housing using hot water and scent-free dish soap. Rinse thoroughly. Cut open the
small end of the sealed bag of a new RO membrane. Hold the membrane with the bag to avoid
contamination and insert it into the housing. (Step 6, p8.)
5. Check the O-ring on the open end of the membrane housing. It is recommended to replace it
every 3 years to prevent leaks.
6. Twist the membrane housing cap back on by hand. Use a wrench for a final ¼turn if necessary.
DO NOT overtighten.
7. Flush the system.
Stage 5: Replace every 12 months
This entire cartridge is replaced by removing the elbow fittings on both ends and using them for
the new cartridge.
How to replace the stage 5 inline cartridge
1. Disconnect the tubing from the Quick-Connect fitting on both ends. Unscrew each fitting.
Unwrap a new cartridge, replace the Teflon tape on the fitting threads if necessary, follow the
arrow sign on the label to screw the correct fitting on each end, and reconnect the tubing.
O-rings: Replace every 3 years or sooner if leak happens at O-ring.
The package comes with 3 spare O-rings for the pre-filter housing, and 1 spare O-ring for the
membrane housing. Please save them with this manual.

Troubleshooting Guide
The filter housing is leaking.
First check that all filter cartridges are sitting
upright inside the canisters. If so, then check
that the O-ring is in place. It should fit snug, not
too tight or not too loose. Confirm that it stays
in place when tightening the canister.
The tank appears full; yet, only a small
amount of water comes out of faucet.
There are two likely causes: the tank has low
pressure or a broken bladder. You can trouble
shoot with the following steps:
• Shut o the main water supply.
• Place a bucket under the tank and remove
tank by disconnecting the ball valve.
• Dump the water from the tank through the
top stem by turning it upside down. You
may add air from the front valve to help
empty the water.
• Use a gauge at the front air valve to check
tank pressure. It should be within 7-10 PSI
while empty. If too low, you can use a bicycle
pump to add more pressure to the tank.
• Re-connect the tank to the system and
turn on the water supply.
Continuous drain.
All RO systems create drain water. The drain water
should run only when the system is making water.
The drain should stop when tank is full. If the drain
runs for more than 3 hours, the problem might be
caused by the following reasons:
• Faulty automatic shut o valve (at the pure
water outlet of the membrane housing),
• Faulty flow restrictor (the tube marked
“flow 300” and connects to the drain line),
• Low tank pressure.
Cloudy water.
With a new system, air bubbles in water or ice
may occur and normally clears up in two weeks.
If cloudyness persist, check the membrane
with a TDS meter. If the meter reads below 75%
rejection, the membrane needs to be replaced.
High TDS level in RO water.
The RO system should produce a TDS rejection
rate of about 85-95%. Check the following:
• Confirm that the RO membrane stage 4 has
been installed.
• If your membrane stage 4 is installed and
over 2 years old, it is time to replace it with
a new one.
• Confirm the tubing connection is correct
(Step 7, p8.) High TDS levels can result if the
drain line and pure water line are reversed.
The water has a funny taste or odor.
Possible Cause Solution
Stage 3 Carbon post filter
has been installed more
than 6 months.
Replace Filter.
Storage Tank may be
contaminated.
Clean, flush and sanitize
the Storage Tank. Replace
filters.
Product water and Drain
water lines are reversed.
Correct plumbing.
High TDS levels. See High TDS Levels in
Product Water Section
Sudden drop in RO water production.
There are a few potential factors causing the
problem:
• Feed water valve is plugged or closed.
• Sediment/Carbon prefilter or Carbon Post
Filter is clogged.
• Low incoming water pressure.
• Reverse Osmosis Membrane is dirty.
• Air pressure in Storage Tank is low.
• Air Bladder in Storage Tank is ruptured.
• Storage Tank valve is closed.
• No water to drain. Drain Flow Restrictor is
clogged.
• Check Valve on RO Membrane Housing is
stuck.
• The Automatic Shut-O Valve is
malfunctioning.
