*Water output will decrease as the tank empties and will only be a quick drip or slow
stream when the tank is empty. This is normal.
**Water will run down the drain whenever the system is filling the tank. How long it
runs depends on water pressure, filter and membrane condition, membrane size,
system configuration, and amount of water taken from the tank. Average times for
refilling the tank range from 30-45 minutes for a couple glasses of water up to 4-5
hours to completely fill the tank.
***The standard tank will hold a maximum of about 3.2 gallons of water, the upgrade
tank will hold about a maximum of about 10.3 gallons of water. Actual storage capacity
may be less depending on system configuration and water pressure.

4. Systems with UV Check flow coming out of the UV filter, if
flow is reduced there is an obstruction in the UV housing.
Unplug the UV before checking for obstructions
5. Remove the waste water (yellow) line from the membrane
housing (a capillary flow restrictor is installed in the line) and
check water flow; there should be a steady flow of water. If
there is no water flow and water is reaching the membrane,
the membrane is fouled and needs replaced.
6. Check flow after the flow restrictor. Flow should be reduced,
but should still be coming out in a steady stream. If flow is the
same or if flow is completely gone, the flow restrictor is
defective and needs to be replaced.
7. Check the line coming from the check valve on the membrane
to the auto shut off valve (refer to the connection diagram if
you are unsure where the check valve is). You should get a
steady drip or a slow stream. If there is no flow, remove the
check valve (simply unscrew counterclockwise) and test again.
If flow is achieved by removing the check valve, replace the
defective check valve. If removing the check valve does not
solve the problem, either your pressure is too low (common on
new installations, 40psi minimum is required) or the
membrane is fouled (more common on older systems).
8. Check line connecting the auto shut off to the T-fitting on the
next filter (refer to connection diagram if you are unsure which
filter is next). Flow should be the same here as it was coming
out of the membrane. If not, the auto shut off valve is stuck
and not allowing water through, replace the auto shut off
valve.
9. Ensure tank ball valve closed and check the flow of water after
each of the inline filters. (Inline filters may include post filter,
pH filter, and alkaline filter, depending on your system.)
Remove the line after each filter and check the water flow.
Flow should be close to the same through each filter as it was
coming from the auto shut off valve. If significantly reduced
flow is found after one of the filters, replace the filter.
10. Remove the line connected to the faucet (blue) and check flow
there. If flow is restricted, replace the tubing between the
final filter on the system and the faucet. If flow through the
line is fine but there is no water from the faucet, replace the
faucet.

Troubleshooting
Tracing Water Flow
Note: Tank valve needs to be shut off unless otherwise indicated.
When tracing water flow, shut feed water valve off and remove
line to be checked from fitting. Turn feed water valve back on,
ensuring it is fully open before checking flow. Repeat this process
with each step until the problem is found.
1. Check feed water line (red) connected to the inlet side of the
clear housing on the bottom of the system. Flow should be
strong and forceful. If not, ensure water supply is on and feed
water valve is open. If water supply is on and feed water valve
is open and still no water, replace the line connecting the
system to the feed water valve.
2. Check flow on line coming from 3rd (white) housing connected
to the auto shut off valve (ASV, the white block behind the
membrane with 4 connections). Flow should be close to the
same as before the filters. If not, verify the middle filter is
installed with the gasket end facing up. If installed correctly
and flow is still significantly reduced, replace the filters.
3. Directly across the ASV is a line running to either the single
fitting end of the membrane OR the UV filter, depending on
system configuration. Check the flow, if flow is significantly
reduced or none at all, the auto shut off valve is blocking flow.
Open the faucet to relieve any pressure on the system, and
check again. If flow is still impeded, the auto shut off is worn
out and needs replaced

20 Revised 10/2014
the water in your system may still contain bacteria. The bacteria
still has the opportunity to grow in your system and damage your
membrane, so even if you have a UV filter it is recommended that
you use this procedure. We recommend sanitizing during a filter
change, that way the old filters can be removed and thrown away,
the system can be sanitized and new filters put in.
Sanitization Procedure:
1. Turn off the feed water supply. This is done by closing the
angle adapter ball valve. The valve is closed when the handle is
at a 90°angle to the tubing (when handle is NOT parallel to
tubing).
2. Open the faucet to allow the tank to empty. This water may be
saved if so desired. Leave the faucet open until no more water
comes out.
3. Close the faucet.
4. Pull the system out to where it can be easily worked with. If
the system was installed with enough tubing to do so, simply
pull it out to where it can be worked on. If the system does not
have enough tubing, you will need to disconnect the lines to
pull it out. (When changing the membrane, it helps to have a
towel handy, as some water may leak out.) Make note of which
tube goes where to ensure the system will be hooked up the
same way it was.
5. Remove all filters and the membrane from their housings;
leave the inline filter(s) (the post filter, as well as the DI &
pH/Mineral filter if the system has them) in place.
6. Add one capful (2 tsp or 10ml) of 5 ¼% bleach (any household
bleach, such as Clorox®, will work) to each filter housing and
the membrane housing.
7. If the system was unhooked, hook it back up now.
8. Open the feed water supply and allow water to fill the
housings. Open the tank valve and allow 5 - 10 minutes for
water to fill the tank.
9. Open the faucet to allow solution to enter lines. Close the
faucet and feed water line when water begins to come out of
the faucet.
10. Let solution stand in system for 15 minutes.
11. Open the feed water line and faucet and allow water to run
through the system, 15 - 20 minutes is recommended to

Pre-installation Preparation
IMPORTANT: Read through the entire instruction manual before
beginning installation. Abundant Flow Water is not responsible
for any damage, injury, or monetary loss incurred from failure to
read and follow instructions.
Brief Technical Summary of the Filtration Process
Water enters the filter system and passes through a series of pre-
filters. The sediment filter removes particulates such as dirt and
sediment. The GAC (granular activated carbon) removes a wide
range of chemicals (including chloramines), tastes, and odors. The
carbon block filter removes chlorine and any tastes and odors the
GAC filter might miss. The pre-filters protect the membrane and
should be changed regularly to ensure maximum performance
and membrane life. (NOTE: Some special order systems may have
different pre-filters). The water is then purified using a process
called reverse osmosis (RO). As the heart of the purification
system, the RO process uses a semi-permeable, spiral-wound
membrane to separate and remove dissolved solids, organic,
pyrogens, sub-micron colloidal particles and bacteria from the
water. Feed water is delivered under pressure at about 60 PSI
through the permeator where water permeates the minute pores
of the membrane and is delivered as purified water. Impurities in
the water are concentrated in the reject stream and flushed to
drain. The RO Membrane is capable of removing 90% to 95% of
contaminates present in the water. The optional UV filter uses
ultra violet light to destroy bacteria and viruses. The optional
inline pH/mineral filter ensures a neutral pH and adds beneficial
minerals back into the water. The optional alkaline filter increases
water alkalinity, adds additional minerals, and lowers oxygen
reduction potential (ORP). The post filter gives a final polishing to
ensure clean tasting water.
Water Purification Summary:
Stage 1: Sediment - Traps dirt, sediment, & particulates
Stage 2: GAC - Chloramines, Tastes, Chemicals, & Odors
Stage 3: Carbon Block - Chlorine, Tastes, Chemicals, & Odors
Stage 4: UV (Upgrade) - Kills bacteria, viruses, & cysts
Stage 5: RO TFC Membrane - 90-95% of contaminates
Storage: Pressurized Tank

2 Revised 10/2014
Stage 6: pH (Upgrade) - Neutralizes acid/adds minerals
Stage 7: Alkaline (Upgrade) – Raise alkalinity, lower ORP
Stage 8: Post - Polishing filter to ensure clean, fresh tasting water
Delivery: Dedicated RO Faucet
System Maintenance Summary:
Filters: Filter maintenance will vary depending on water quality
and water usage. For most homes with average water quality and
usage, every 6 months is usually sufficient. For higher water use
and/or dirtier water, more frequent filter changes may be needed.
Filters need to be changed at least once a year. If equipped, the
UV bulb should be changed every 12 months. Refer to the front
cover for the filter set specific to your system. Replacement filters
available online at www.afwfilters.com or by calling 785-735-9769.
Membrane: Average membrane life varies from 2-4 years
depending on a number of factors. Reduced water production or
quality may indicate a fouled membrane, or a TDS meter can be
used to monitor the membrane. The membrane should be
changed at least every 4 years.
Sanitization: It is recommended that the system is sanitized once
a year to prevent bacterial build up and ensure a clean system.
Even in homes with no known bacteria problem or bacteria
prevention in place it is a good idea to sanitize the system. If used
in a home with a known bacteria problem, more frequent
sanitization may be a good idea.
Pre-installation Check List
1. Read through and familiarize yourself with these instructions
and the installation process. This will ensure you have the proper
tools, parts, and abilities to install the system before beginning,
rather than having to stop halfway through because of missing
parts, incorrect tools, or the inability to perform a required task.
2. Check and follow all local plumbing. Going against plumbing
codes is illegal, and can cause problems. Abundant Flow Water is
not responsible for any problems resulting from improper
installation or installations violating local plumbing codes.
3. Determine installation locations, including feed water supply,
drain, faucet, filter system, and storage tank. Ensure you have
room for everything, and plan room for future filter changes.
4. Familiarize yourself with the quick connect fittings. Your system
uses quick connect fittings. There is a collet ring at the end of the
©2014 Abundant Flow Water Systems, Inc. 19
the system is turned off.
12. If the system was unhooked to change the filters, hook it back
up now. Open the angle adapter ball valve on the feed water
line, and open the tank ball valve.
13. Open the faucet, and tilt the system back and forth and side to
side to help work the air out of the lines.
14. Allow the system some time to start producing water from the
faucet, depending on the system and water pressure this may
take up to 30 minutes. Once you are getting a steady flow of
water (anything from a steady drip to a small stream,
depending on membrane size and water pressure), shut the
faucet off.
15. Allow the system to fill the tank. Depending on the system and
water pressure, this can take anywhere from 1 - 5 hours.
16. Once the tank has filled, open the faucet, allowing all the
water to drain until flow from the faucet is down to the slow
drip or stream seen in step 14. This flushes the system,
cleaning the membrane and preparing it for use.
17. Repeat steps 15-16 at least once to ensure thorough flushing
of the new filters.
18. Your membrane is now changed and the system is ready to use
again.
Estimated System Life
The estimated system life is typically about 10 years. After this
point wear and required replacement costs typically outweigh the
costs and advantages of replacing the entire system with a new
unit.
System Sanitization:
Important Note: Reverse Osmosis water purification systems
remove most contaminates in drinking water, however there is no
guarantee on the quality of the final product. In addition to that,
it is important that you are aware that bacteria can grow within
your RO system, even in homes with no known bacteria problems,
and thus we recommend using this sanitization procedure at least
one a year to prevent and eliminate any bacteria growth. If using
on a water supply that has a known bacteria problem, more
frequent sanitization may be necessary. If your system has a UV
filter this will eliminate bacteria in your final product water,
however, the UV filter is one of the last stages, so the majority of

To change the membrane:
Note: The tank will need to be emptied when replacing the
membrane. If you would like to save the water in the tank for use,
follow the instructions below, opening the faucet and collecting
the water from the tank after turning the feed water off.
1. Turn off the feed water supply. This is done by closing the
angle adapter ball valve. The valve is closed when the handle is
at a 90°angle to the tubing (when handle is NOT parallel to
tubing). If saving water from the tank, do so after closing the
valve.
2. Shut the ball valve on the tank. The valve is closed when the
handle is at a 90°angle to the tubing (when the handle is NOT
parallel to the tubing).
3. Open the faucet to release any remaining pressure.
4. Pull the system out to where it can be easily worked with. If
the system was installed with enough tubing to do so, simply
pull it out to where it can be worked on. If the system does not
have enough tubing, you will need to disconnect the lines to
pull it out. (When changing the membrane, it helps to have a
towel handy, as some water may leak out.) Make note of which
tube goes where to ensure the system will be hooked up the
same way it was.
5. Disconnect the tube feeding the membrane (the tube going to
the single fitting on the membrane housing cap). If unsure how
to disconnect the quick connect fittings, refer to the section
on quick connect near the beginning of the manual.
6. Remove the membrane housing cap (when looking at the
fitting on the cap it will turn counterclockwise to loosen).
7. Remove the membrane from the housing. A pair of needle
nosed pliers may be needed to grip the end of the membrane.
To remove, gently pull with a twisting motion and the
membrane should slide out.
8. Lubricate the O-rings on the membrane with a silicon based
lubricant (vegetable oil may be used if silicon lubricant is not
available), and push back into the housing.
9. Lubricate the O-ring on the membrane housing (some
housings have 2) and screw the membrane housing cap back
onto the housing.
10. Push the tubing back into the fitting on the membrane cap.
11. If the filters need changed, now is a good time to do so, since
©2014 Abundant Flow Water Systems, Inc. 3
fitting that grips the tubing and holds it in place. To remove,
simply hold the collet ring against the fitting and pull the tubing
out. To replace tubing, just push it into the fitting, it will slide in
easily about 1/4” then stop, apply a little more pressure and it will
slip in another 1/8” or so and seal in place.
5. Familiarize yourself with any purchased upgrade kits. If you
ordered any kits to upgrade your system, read through the
instructions on how to install it, as it is usually easier to install any
upgrades before installing the system.
6. Check to ensure there are no missing parts. Use the parts
checklist on the following page to make sure all the parts listed
are present. If anything is missing, call us and we will get
replacements out as soon as possible.
7. Assemble the tools you will need. Depending on where the
system is being installed and the plumbing, the tools needed may
vary. You will need a Phillips head screwdriver, drill, wrenches,
pliers & PTFE tape. You will also need a sharp knife or scissors to
cut the tubing (when cutting tubing, ensure the end is smooth and
straight, this will ensure a good seal and prevent leaks). This list is
just a start, reading through the instructions and determining
where you are installing the system will give you a better idea of
everything needed.
8. Ensure the following conditions are met:
Feed Water
Condition
Minimum Maximum
Inlet Pressure 40 psi 80 psi
Temperature 40°F 100°F
pH Level 3 11
TDS Level 0 ppm 2000 ppm
For pressure less than 40psi a booster pump will be required. If
pressure is less than 50psi a booster pump or permeate pump is
recommended. If other conditions are not met contact us for a
solution. NOTE: Failure to meet the above conditions will void the
warranty on the system.
Parts Checklist
In addition to the RO system, faucet, storage tank, and UV
transformer (if a UV was ordered), you should have the following

filtration, these instruction will walk you through getting the
additional filtration setup on your new system. If you did not get
additional filtration, skip to “Faucet Installation”
1. First, remove all the filter upgrade kit parts to ensure that
everything is present. You should have: the inline filters relevant
to the exact system you ordered (see connection diagram for
available filters), two (2) quick connect fittings for inline filters
that have threaded ports (if applicable), two (2) clips for each
filter, a 2-3 foot length of tubing, and one (1) stem elbow fitting
for each filter (two (2) for the UV filter).
2. Next, install the quick connect fittings into any filters that have
threaded openings. Put 2-3 wraps of PTFE on the threads of each

handle is at a 90°angle to the tubing (when the handle is NOT
parallel to the tubing).
3. Open the faucet to release any remaining pressure.
4. Unscrew the cap on the UV filter and carefully remove. The
quartz sleeve is secured inside the cap.
5. Inspect the sleeve. The cleaner it is the better it will work. Light
build up can be cleaned off with a vinegar solution, be sure to
avoid touching the sleeve with bare hands as fingerprints can
cause buildup that will block the UV light.
6. If heavy build up is present the sleeve will need to be removed
and thoroughly cleaned (by soaking in a vinegar solution) or
replaced.
7. To remove the sleeve, gently grip and twist (clockwise or
counterclockwise doesn’t matter, just stick with one direction,
the goal is to loosen it) while pulling it away from the cap.
NOTE: Care must be taken when removing the sleeve, as it can
break if too much force is applied, creating sharp edges that
can cause injury.
8. To replace the sleeve, use silicon based lubricant or vegetable
oil (NOT VASELINE) and lubricate the O-rings inside the cap.
Gently push and twist the sleeve in place until it is fully seated
in the cap.
9. Screw the cap back onto the UV filter, and turn your water back
on, checking for any leaks
Membrane:
The RO membrane will last an average of 2 –4 years, depending
on water quality, water usage, frequency of filter changes, and
quality of filters used. Reduced water quality, reduced production
rate, or no production can be an indication of a fouled membrane,
but there may not always be these signs to tell you the membrane
is bad. The best way is to monitor the rejection rate of the
membrane using a TDS meter. A functioning membrane should be
removing a minimum of 90% of contaminates under normal
conditions. To test this, simply compare the TDS of your tap water
to the TDS of the water from the membrane (before it goes to any
other filters). For example, if your tap water has a TDS of 400ppm,
after the membrane your TDS should be 40ppm or less. If you do
not wish to use a TDS meter, it is recommended that you change
your membrane at least every 4 years.

warranty on the system. We are not responsible for any damaged
caused by using Vaseline or other petroleum lubricants. To ensure
a good seal and minimize any possibility of leaks, it is
recommended you replace your O-rings periodically, usually every
1-2 years.
Housings
With the regular stress of removal and tightening, filter housings
will weaken over time. To help prevent unwanted system failure
the filter housings on your system need to be replaced every 5
years.
UV Filter:
The UV filter uses a bulb to kill bacteria. When the filter is plugged
in and operating, the white cap where the wire comes out will
glow a purplish color. If you ever notice that the filter is not
glowing it means the UV bulb is no longer working. IMMEDIATELY
STOP using the system, as bacteria may be contaminating your
water. Replace the bulb and sanitize the system to ensure safe,
treated drinking water. The bulb does wear out and needs to be
replaced; recommended replacement is every 12 months. It is
important to note that the bulb may glow for longer, but the
intensity of the bulb diminishes over time and after 12 months
full, effective treatment is not assured.
Buildup on the quartz sleeve can also decrease the amount of
effective light that treats the water, so regular checking and
cleaning of the sleeve is recommended.
To change the lamp:
The lamp is enclosed inside a quartz sleeve, so the water does
NOT need to be shut off to change the lamp. Unplug the white
wire from the transformer and grasp it near the white cap on the
end of the filter. Ensure you have a firm grip on both the filter and
the wire, and pull on the wire. The white cap will pull out with the
lamp. Then, simply push the new lamp in place.
To clean/replace the quartz sleeve:
1. Turn off the feed water supply. This is done by closing the angle
adapter ball valve. The valve is closed when the handle is at a
90°angle to the tubing (when handle is NOT parallel to tubing).
If saving water from the tank, do so after closing the valve.
2. Shut the ball valve on the tank. The valve is closed when the
©2014 Abundant Flow Water Systems, Inc. 5
fitting and tighten until snug, making sure to not over-tighten,
which would cause the filter to crack or could strip out the
threads.
3. Now we will install the filter(s) in the order shown by the
diagram on the back of this sheet. Start by installing the UV filter
(if applicable). First, cut the line between the auto shutoff valve
(ASV) and the membrane housing, making sure that you leave
enough tubing coming from the ASV to reach the UV filter. Next,
place a stem elbow on the end of the piece of tubing. Then run a
piece of tubing from the membrane housing cap to the opposite
side of the UV filter. Place a stem elbow on the end of this tubing
that connects to the UV filter also. Connect the other end of the
tubing to the membrane housing. Place the relevant clips onto the
membrane housing, push the UV filter into the clips, and insert
the stem elbows into the UV filter.
4. Next, disconnect the tee fitting from the carbon post filter that
is currently installed on the RO system and remove the filter.
Place the relevant clips onto the membrane housing, then push
the first filter into the clips, making sure the water flow is going
the same direction as the carbon filter was going. Insert the tee
fitting into the input side of this first filter.
5. Follow the same process for each filter, making sure that the
flow coming out of the previous filter enters the input side of the
next filter, following the direction of flow indicated on the filter.
Faucet Installation
Locate the installation point for the faucet; you will need a hole at
least 1/2” in diameter for the RO faucet shank. If the sink has a
sprayer the RO faucet may be installed in the hole used for the
sprayer, simply disconnect the sprayer and plug the sprayer
connection. If the sprayer hole is not an option you will need to
drill a hole. To drill a hole, determine where it will be located
before starting. You will need a 2” flat surface no more than 2”
thick. Ensure the chosen location will not interfere with anything
below, and position the faucet so it will empty into the sink and
can swivel freely for convenience. Once you have confirmed your
faucet location, proceed with drilling the hole in your sink.
Drilling a hole for the faucet
Be careful when drilling the faucet hole. Be sure to drill slowly to
prevent chipping or scratching, and be sure to wear proper safety

equipment to protect yourself.
1. Mark the center of the hole with a pencil, marker or other
marking device
2. Determine your sink type:
a. Porcelain, Enamel, or Ceramic on Metal: Using a 1/4”
masonry bit, carefully (using a slow speed and light pressure)
drill a pilot hole through the sink. If drilling through a ceramic
on metal sink, stop when you reach the metal portion, switch
to a 1/4” metal cutting bit and continue.
b. Stainless Steel or Cast Iron: Using a 1/4” metal cutting bit,
carefully drill a pilot hole through the sink.
3. Continue to enlarge the pilot hole until the hole is 1/2".
4. Clean up any rough or sharp edges.
Note: Air gap faucets are required by some local plumbing codes.
These faucets require a 1-1/4" hole in the sink rather than the 1/2"
hole required by the standard RO faucet. If a hole large enough (1-
1/4") is not already available,
special tools (such as a chassis
punch or a Relton cutter) may
be required. Contact your
local plumber or contractor if
you are unable to make the
required hole yourself. If an
air gap faucet is required, we
provide a number of different
styles and colors; contact us
for pricing and availability.
Once the faucet location has
been prepared, move on to
the next step: Mounting the
Faucet.
Mounting the Faucet:
1. Remove all parts from the
RO faucet shank. Using
Figure 1, gather the pieces
shown. NOTE: The diagram
is for the standard RO
faucet, an upgraded faucet
©2014 Abundant Flow Water Systems, Inc. 15
has them.) To replace them, remove the tubing and/or fittings
from each end of the filter (refer to section on quick connect
fittings near the beginning of the manual if you are unsure
how to do this) and replace in the new filter, paying careful
attention to the direction of flow as indicated on the filter, and
ensuring the new filter is installed in the same direction as the
old filter. Do this with each inline filter your system has.
8. If the system was unhooked to change the filters, hook it back
up now. Open the angle adapter ball valve on the feed water
line, and open the tank ball valve.
9. Open the faucet, and tilt the system back and forth and side to
side to help work the air out of the lines
10. Allow the system some time to start producing water from the
faucet, depending on the system and water pressure this may
take up to 30 minutes. When the water first comes out it may
be black as the carbon fines in the post filter rinse out, this is
normal. Once you are getting a steady flow of water (anything
from a steady drip to a small stream, depending on membrane
size and water pressure), shut the faucet off.
11. Allow the system to fill the tank. Depending on the system and
water pressure, this can take anywhere from 1 - 5 hours.
12. Once the tank has filled, open the faucet, allowing all the
water to drain until flow from the faucet is down to the slow
drip or stream seen in step 10. This flushes the system,
cleaning the filters and preparing them for use.
13. Repeat steps 11-12 at least once to ensure thorough flushing
of the new filters.
14. Your filters are now changed and the system is ready to use
again.
O-rings:
The filter housings on the system utilize O-rings (black rubber
washers, located in a grove right below the threads on the
housing) to seal themselves. To prevent leaks it is recommended
to check the O-rings every time the housings are opened. Ensure
there are no nicks, kinks, or gouges in the O-ring. If damage is
found, replace before continuing, otherwise, use a silicon based
lubricant (vegetable oil can be used if no silicone lubricant is
available) and lubricate the O-ring before replacing the housing.
DO NOT USE VASELINE! This will damage the O-rings and void any

14 Revised 10/2014
1. Turn off the feed water supply. This is done by closing the
angle adapter ball valve. The valve is closed when the handle is
at a 90°angle to the tubing (when handle is NOT parallel to
tubing). If saving water from the tank, do so after closing the
valve.
2. Shut the ball valve on the tank. The valve is closed when the
handle is at a 90°angle to the tubing (when the handle is NOT
parallel to the tubing).
3. Open the faucet to release any remaining pressure.
4. Pull the system out to where it can be easily worked with. If
the system was installed with enough tubing to do so, simply
pull it out to where it can be worked on. If the system does not
have enough tubing, you will need to disconnect the lines to
pull it out. (When changing filters, it helps to have a towel
handy, as some water may leak out.) Make note of which tube
goes where to ensure the system will be hooked up the same
way it was.
5. Remove the first filter housing. To remove, use the filter
housing wrench supplied with your system. When looking
down at the top of the system, the filter housing will turn
clockwise to loosen, counterclockwise to tighten. Once the
filter housing has been removed, pull the filter out and replace
with the new one. At the top of each housing is an O-ring,
when changing filters it is recommended to remove the O-ring
and check for any damage such as nicks, gouges, or kinks. If
damage is found, replace before continuing, otherwise, use a
silicon based lubricant (vegetable oil can be used if no silicone
lubricant is available, avoid petroleum based lubricants such as
Vaseline) and lubricate the O-ring, place it in the filter housing
and screw the housing back in place. This will help prevent
leaks.
6. Repeat step 5 with each housing, replacing the old filter with
the similar new filter and checking the O-rings. If any of the
filters have only one gasket (the middle filter on most systems
will have only one gasket) the filter will need to be installed
with the gasket at the top of the housing, unless dictated
otherwise by the filter itself.
7. Once the pre-filters (the filters in the housings) have been
changed, it is time to change the inline filter(s) (the post filter,
as well as the pH/Mineral filter & Alkaline filter if the system

may look slightly different than the one pictured, but the parts
should be similar.
2. Place color matched washer onto faucet shank, followed by the
small rubber washer. Position the faucet in the mounting
location by sliding the shank through the mounting hole.
3. On the underside of the mounting hole, slide the large rubber
washer and locking washer in place, then tighten the faucet nut
in place until secure.
4. Once your system is installed, you can hook up the product line
to the faucet. The best way to do so is to wrap the bottom of
the faucet shank with 3-4 wraps of PTFE tape, then attach the
quick connect faucet fitting. The product line will then push
directly into the fitting. An alternate method of attaching the
line is to slide the line nut over the product line, followed by
the ferrule, then push the insert into the end of the line. Once
that is done simply push the end of the product line into the
bottom of the faucet shank as far as it will go, then tighten the
line nut to secure it in place.
Storage Tank:
As the RO system makes water it pushes it into a tank to store it,
and a pressurized bladder in the tank pushes it back out (through
the same opening) when requested (such as opening the faucet).
The large male threaded fitting on one end of the tank is the inlet
and outlet of the tank. A pressure valve on the side of the tank
(usually covered with a blue screw-on cap) is used only for
checking and adding air to the bladder. The tank is shipped with 4-
6psi of air pressure in the bladder, and is sufficient in most cases.
Pressure may be increased to no higher than 10psi when the tank
is empty, this will cause water to come out of the faucet a little
faster if so desired. NOTE: As the tank is emptied, pressure from
the faucet will decrease, this is normal.
To Prepare the Tank:
1. Wrap the threaded nipple on the end of the tank with 3-4 wraps
of PTFE tape.
2. Install tank ball valve on prepared nipple, hand tight only. When
connecting the system the product line connects here.
Feed Water Installation:
1. The feed water assembly consists of a 3/8” angle valve adapter.

8 Revised 10/2014
2. Locate cold-water angle shut off valve underneath the sink,
usually on the right side, and turn it off. Open cold water faucet
to release the pressure. On single handle faucets, turn the hot
water off to prevent cross over. If water is not stopped
completely, turn off main water supply
3. The angle shut of adaptor is installed directly on the on the cold
water angle shut off valve.
Flex line Instructions
Loosen nut and separate cold water line
from angle shut off valve. Ensure the O-
ring is in place on the angle valve
adapter and screw in place on the angle
shut off valve. If washer in flex line is
worn or damaged, replace before
continuing to prevent any leaks. Gently
bend flex line so that it will fit over the
angle valve adapter and tighten flex line
onto angle valve adapter.
Copper Instructions
Loosen nut and separate cold water line
from angle shut off valve. You will need
to cut a piece of the copper tube about
3/4" to 1" (measure to determine the
exact cut needed) so the angle valve
adapter can fit between the angle shut
off valve and the copper line. Ensure the O-ring is in place on
the angle valve adapter and screw in place on the angle shut off
valve. If washer in copper line is worn or damaged, replace
before continuing to prevent any leaks. Push the copper pipe
into the angle valve adapter and tighten down the compression
nut.When connecting the system the feed water line connects
to the angle valve adapter.
Drain Saddle Installation:
The drain saddle consists of two (2) halves, (one half has a fitting
on it), two (2) bolts with nuts, & a rubber seal. It is used to direct
the waste water from your system down the drain. Depending on
where the saddle is located, you may hear water running down
the drain when the system is making water, this is normal. If the
sound is annoying, the drain line may be pushed farther in to help
©2014 Abundant Flow Water Systems, Inc. 13
NOTE: The system will automatically turn on whenever water is
drawn out of the tank. When the system is on & making water
there will be water going down the drain, this is normal. Once the
tank is full pressure build up in the system will activate the auto
shut off valve, cutting the water supply to the membrane and
stopping the flow of water down the drain. How long it takes for
the wastewater to shut off depends on many variables, including
the amount of water taken out and water pressure.
System Maintenance
Filters:
Filters need changed regularly to ensure protection of the
membrane and high purity water production.
Refer to the chart below for the specific filter set needed for your
system. Filter kits, as well as individual and specialty filters may be
ordered securely online at www.afwfilters.com or by calling 785-
735-9769. With average usage and normal water conditions filters
should be changed every 6 months. The more water you use or
the dirtier your water the more often you will want to change
filters. If the first filter (sediment filter) gets dirty quickly it may
need changed more often than the rest, part number for the
individual sediment filter is RF-SED10-5. All filters (excluding the
membrane) should be changed at least every 12 months.
To change filters:
Note: The tank will need to be emptied when changing filters. If
you would like to save the water in the tank for use, follow the
instructions below, opening the faucet and collecting the water
from the tank after turning the feed water off.

from the UV filter into the transformer and plug the transformer
into any standard 110v outlet. When the UV bulb is working you
will see a purple glow from the end of the UV filter. NOTE: When
first plugged in the UV filter may take a minute or two before it
lights up, this is normal. Once plugged in the light will remain on
and should not be unplugged except to change the bulb, this
ensures effective treatment.
Preparing the system for use:
Note: Ball valves are open when the handle is
inline (parallel) with the tubing (Fig. 5)
1. Double check all the connections, ensure they
are all connected and secure.
2. Ensure all filter housings are tightened down, using the filter
housing wrench included with your system.
3. Slowly open the ball valve on the feed water connection.
Water will fill the filter housings.
4. Open the tank ball valve.
5. Check all connections, ensuring there are no leaks.
6. Open the faucet and tilt the system from side to side and back
to front, this helps work the air out of the system.
7. Allow the system some time to start producing water from the
faucet, depending on the system and water pressure this may
take up to 30 minutes. When the water first comes out it may
be black as the carbon fines in the post filter rinse out, this is
normal. Once you are getting a steady flow of water (anything
from a steady drip to a small stream, depending on membrane
size and water pressure), shut the faucet off.
8. Allow the system to fill the tank. Depending on the system and
water pressure, this can take anywhere from 1 - 5 hours.
9. Once the tank has filled, open the faucet, allowing all the
water to drain until flow from the faucet is down to a slow drip
or stream (about 5-10 minutes for the standard tank). This
flushes the system, removing any preservatives from the
membrane and cleaning off the filters.
10. Repeat steps 8 & 9 at least once, ensuring the system is
flushed and ready to use.
11. The system is now ready to provide safe, purified water!

alleviate it. Please note, pushing the drain line in farther than
normal requires a good amount of force, as you are forcing the
tubing past the typical stopping point. If doing so, please use
caution to prevent any injuries.
To install:
1. The drain saddle
should be installed
above the “P” trap
and on the vertical or
horizontal tailpiece
(see figure 3). A
horizontal location is
ideal, as it is more likely the waste water will be heard if
installed on a vertical pipe.
2. The position of the hole on the pipe should be marked and
drilled with a 1/4" bit. If using a horizontal pipe, ensure the hole
is made on the top of the pipe, so that standing water in the
pipe will not leak into the drain saddle. NOTE: Drill through one
side of the pipe only!
3. Take the backing off of the rubber seal, center over the hole
just drilled, and stick in place.
4. Position the fitting half of the
drain saddle over the hole in the
drain pipe, then position the
back half on the opposite side of
the drain. Place one of the bolts
through the fitting half into the back half and loosely thread
the nut onto it. Repeat on the other side. Position the fitting on
the fitting half of the saddle over the drilled hole and seal, then
evenly tighten both nuts, being careful not to over tighten.
When connecting the system the drain line connects to the
drain saddle fitting.
Connecting the system:
Once the previous steps have been completed the system is ready
to be hooked up. To make future filter changes easier, we
recommend positioning the system in a location that is easily
accessed, or allowing enough tubing to move the system to where
it can be easily accessed. This will allow you to change filters and

10 Revised 10/2014
will save time since the system will not have to be unhooked.
We have included the pictures and descriptions along with color
coded tubing to make connecting the system simple. If unsure,
feel free to contact us for assistance. Refer to Pre-installation
section for help with quick connect fittings. Please Note: Pictures
are for reference only, system variations may occur.

Find the line that leads to the faucet on the RO system. Cut line
with sharp knife or scissors. Connect the T-connector to both
ends of the line by pushing tubing into slip connectors firmly.
Cut a short length of tubing to insert into T-connector T-off. Insert
other end of this tubing into shut off valve fitting. Connect tubing
to other end of shut off valve and into ice machine or water
machine. Lengths over 15’-20’ will lose pressure so use shortest
route possible.
