This Aquasafe Reverse Osmosis System has been specically
designed as a DIY (Do It Yourself) unit for easy installation and
maintenace purposes.You will insure a successful installation as
well as reliable operation by carefully reading this manual and
following its operational guidelines.
Your system requires a minimum of 50psi inlet water pressure.
City and municipality water utilities are mandated to provide a
minimum of 50psi however sometimes this is not what results.
If you are on a well system or on city/municipal water supply and
have less than 50psi we highly recommend a fully automatic
booster pump which is found on our websites general parts
and accessories page. We also highly recommend a booster
pump if your water is extremely turbid with ppm counts beyond
600ppm.
The installation instruction that follow are extremely detailed.
if a leak is experienced during installation, please see the Leak
Prevention Section on page 16.
ATTENTION: It is extremely important to change the
lters of your system in order to ensure ultra pure water
is being produced for you and your loved ones, (which
is the whole point to your system) and also to prevent
premature fouling of the TFC Filmtec Reverse Osmosis
Membrane of your system. After your installation is complete,
please read over the Filter Change Schedule section (page
17) and remember to mark on your calendar when your
systems lter changes need to be conducted. Filter changes on
Aquasafe’s Reverse Osmosis Systems are both inexpensive and
very easy to do.

2.0 Take everything out of the box
Examine the contents of the Large and Small parts bag against the photos below. If any pieces are
missing, check the box, sometimes the pieces can fall out of their bags during the system’s journey to
you.
3.0 Remove the protective plastic from the prefilters
Inside each of the three prelter canisters you will nd a prelter with protective plastic for quality as-
surance purposes. Paying close attention to how the lter is sitting inside the prelter housing, remove
the plastic and then reinsert the prelter the same way the prelter was taken out. Do this one at a
time. If by chance you loose track of which lter goes into which prelter canister, the SED (sedimen-
tary lter) is stage one, the GAC (granular activated carbon lter) is stage two and the CCB (coconut
carbon block lter) is stage three. See pictures below of the three prelters. The GAC is the only one
of the three prelters that only goes in one way. The GAC must be placed with the gasket up and the
plastic mesh down.
With the prelters inside each prelter canister, carefully screw the canisters into place. Try to keep the
prelters centered as much as possible during this process. Now, using the large canister wrench from
the Large Parts Bag, tighten each of the prelters with reasonable force in order to seal the lters into
place.

If need be you can use a pair of needle nose pliers or similar tool to grip the white cylinder pro-
truding from the base of the RO Membrane to gain the leverage needed to push the membrane
entirely into its proper position.
4.0 Inserting the R.O. Membrane
The R.O. Membrane is shipped sealed for
freshness. Remove the R.O. Membrane
from its sealed plastic bag and insert the
membrane rmly into the R.O. Housing
(see Fig 4). It can only go in one way, the
end with the two small o-rings is to be
inserted rst.
Please Note: It is extremely important
the two small black “O” rings on the tip
of the membrane seal tightly into place
inside the membrane housing. Please
make sure to insert the membrane as
rmly as possible into the membrane
housing.
When you are certain the Reverse Osmosis
Membrane is rmly in place screw the R.O. Mem-
brane housing cap back into its place (Fig 4) and
then tighten with reasonable force using the
small canister wrench from the Large Parts Bag.
4.1 Inserting the pre-filter elbow adaptors
Using two of the elbow adaptors from the Small
Parts Bag, screw one of them into the“INLET”
(left) side of the three pre-lters (Fig. 5) and the
other into the“OUTPUT” (right) side of the three
pre-lters (Fig 5).
S Please note: Apply 4-7 wraps of Teon
tape, found in the Large Parts Bag, on each of
the elbow adaptors throughout this installation
to prevent any possible leaks.
5.0 Preparing the Feed Water to your system
Found under your sink are the water supply shut o valves to your hot and cold water lines. You will
need to SHUT OFF the cold water valve. Run the hot water for 30 seconds and then feel which line un-
der your sink is warm. SHUT OFF the opposite water line – since that will be the cold water line. After
this valve is o, turn on your sink’s cold water tap to make sure there is NO cold water owing from
your kitchen sink faucet. If you shut the valve o correctly, there should be no cold water owing.

5.1 Special note about braided wire plumbing
Please Note: DO NOT ATTEMPT
TO INSTALL THE NEEDLE PIERCING
SADDLE CLAMP TO BRAIDED WIRE
PLUMBING (Fig. 6).
You can install the needle piercing saddle clamp to
all other forms of cold water lines found under the
common sink, just not the kind of plumbing de-
picted in Fig 6. The braided plumbing in Fig 6 is too
soft a material and will therefore not allow for the
proper seal needed. The inside of braided plumbing lines may vary and therefore may look dierently
from this example. Don’t let this confuse you. If the plumbing line is braided, DO NOT attempt to install
the feed water needed piercing valve to it. If you have this kind of plumbing there is usually a piece of
copper pipe that is located directly under your kitchen sink’s faucet assembly which you can mount to
OR see our 3/8” x 3/8” x 1/4” plumbing adaptor on our website.
5.2 Installing the Needle Piecing Saddle Clamp to the cold water line.
Rotate the horizontal turning bar of the needle piercing valve to the left (counter clockwise) as you
do not want to pierce your cold water line at this stage. Make sure the needle is retracted all the way.
Next, clamp your cold water line TIGHTLY using the needle piercing saddle clamp which can be found
in your Large Parts Bag. (Fig. 7) You will need a Phillips screwdriver and small pair or pliers for this step.
Be sure to install above your
sink’s shut o valve.
DO NOT ATTACH TO THE HOT
WATER PIPE—AS HOT WATER
WILL DAMAGE THE FILTERS
WITHIN YOUR SYSTEM.
DO NOT PIERCE THE COLD
WATER LINE AT THIS
STAGE !
5.3 Connecting the feed water line to your system.
Next, take the 2-4 Inch piece of red tube from the Small Parts Bag and insert it into the elbow on the
“INLET”(left) side of the pre-lters (Fig. 8 - next page), then take the manual shut o valve, also found
in the Small Parts Bag, and attach it to the other end of the red tube (Fig. 8 - next page).

To more easily insert the tubing into the various ttings of your system it
is helpful to remove the blue “C” clip from around the collet and then in-
sert the tubing. After the tubing has been inserted into place, pull lightly
on the tubing in order to make room for the collet and then place the
collet back into its original position. The blue “C” clip holds the collet in its
proper position while the system is in operation.

SPlease make sure to FIRMLY push the tubing into the various ttings throughout this installation.
Now insert the needle piecing saddle clamp’s orange tubing into the other side of the Manual Shut O
valve completing the feed water line pathway to your ltration system.
5.4 Piercing the cold water line
Ensuring the needle piecing saddle clamp is rmly in place, screw down the needle of the saddle
clamp using the horizontal bar on top of the clamp.
Note: You will feel resistance when the needle is piercing the cold water line, so pay attention to the
amount of resistance experienced. This resistance will stop when you have successfully pierced the
cold water line. CAUTION: Do not screw in the needle valve to its maximum depth as you then risk
piercing the opposite side of your cold water line.
After the cold water line has been pierced, turn the horizontal bar on the top of the clamp counter
clockwise (left) until it becomes snug. This retracts the piercing needle creating a path for feed water
to ow into the orange tubing – supplying your system with its feed water.
PLEASE NOTE: Do not turn your home’s emergency cold water shut o back to its ON position yet!
5.5 Flushing of the Pre-filters
Found in your Large Parts
Bag is a coiled length of blue
tubing. Uncoil the tubing
and insert one end into
the “OUTPUT” elbow (right
side) of the three pre-lters
and place the other end of
the blue tubing into your
kitchen sink. (Fig 9)
This will allow for the water to ow through the three pre-lters and then into your kitchen sink, ush-
ing out any and all loose particulates and carbon dust thereby preventing these initial loose particu-
lates from reaching the 4th stage (Reverse Osmosis Membrane) ensuring maximum life span of the
Reverse Osmosis Membrane.

You can now turn your home’s emergency cold water shut o valve back to its“ON”position. Please
note: By turning the cold water shut o valve back to its “ON”position you are allowing for the ow of
cold water to the system. The system’s three pre-lters will then ll with water which will come out of
the blue tube that is placed in your kitchen sink.
Allow the water to run through your system for 20 minutes to ensure proper ushing of the three pre-
lters. After the 20 minute pre-lter ush, turn the manual shut o valve, found on the feed water line
(see Fig 9), 90 degrees to the tubing as this will stop the ow of water to your system.
Next, following the diagram below, remove the blue tubing inserted into the “OUTPUT” (Right Side) of
the prelters that you just used to ush the three prelters.
To remove tubing from any point on
your system simply follow this dia-
gram (Fig. 10) You can easily remove
the tubing from any tting on your
system by removing the blue “C” clip
which will expose the “collet”. Then
simply push in the collet so that it is
ush with the tting and then pull
out the tubing.
Please note: In the future, be sure
to de-pressurize your system before removing tubing from any tting on your system. To de-pressurize
your system you simply need to turn the manual shut o valve, found on the feed water line, to its 90
degree (OFF) position, then turn your tank top valve, found on top of the water holding tank, to the 90
degree (OFF) position and then press down on your faucet. De-pressurizing your system is extremely
easy and takes just seconds.
NOTE: At this stage of the installation you have not yet installed the water holding tank or the faucet
and therefore, by simply turning the manual shut o valve to its 90 degree position, you have success-
fully depressurized the system and you can now remove the blue tubing used to ush the pre-lters
from the“OUTPUT” (right side) of the pre-lters.

Take the short white tube connected to the“IN” side of the 4 way auto shut-o valve (ASV) on the top
of the unit and insert it into the elbow adaptor on the “OUTPUT” (right side) of the pre-lters. (Fig. 11)
Remember to insert the tubing rmly. Next, take the short white line connected to the “OUT” side of
the 4 way auto shut-o valve (ASV) on the top of the unit and insert it into the elbow adaptor on the
cap of the R.O. Membrane housing (Fig 11).
These two white tubes complete the connection between the pre-lters and the R.O. Membrane.
7.0 Setting the Flow Restriction Ratios of your System.
Using the same blue tubing used to ush the pre-lters, insert one end of the blue tubing into the E–Z
Flush Flow Restrictor (Fig 12). After you have inserted the blue tubing into the E–Z Flush Flow Restric-
tor, insert the other end of the blue tubing into your kitchen sink. The water that will ow through
your E-Z Flush Flow Restrictor is referred to as “BRINE” water and will discharge into your drain washing
away the harmful particulates removed by the R.O Membrane.
Next, get a bowl or a bucket and place it under the short piece of blue tubing that is coming out of the
auto shut-o valve (ASV). The water that will ow out of the short piece of blue tubing that is com-
ing out of the auto shut-o valve (ASV) is the puried water produced by the R.O. Membrane and is
referred to as“PERMEATE” water.
Now, turn the dial on top of the E–Z Flush Flow Restrictor clockwise (Right), entirely closing the valve
of the E–Z Flush Flow Restrictor and then turn the Manual Shut-O Valve (Fig.12) found on the feed
water supply line of your system to its “ON”Position. Within a moment PERMEATE water will begin to
ow out of the short blue piece of tubing coming out of the Auto Shut O Valve (ASV), at the rate of a
very fast drip to a slow trickle. Air inside the R.O. Membrane will be forced out causing the fast drip or
slow trickle to sputter with the air escaping. Wait 2-3 minutes for the air to fully purge so that a steady
output is achieved from the R.O. Membrane.
Next, carefully open the dial on-top of the E-Z ush Flow restrictor counter clockwise (left) VERY SLOW-
LY until the amount of BRINE water owing through the E-Z Flush Flow Restrictor is owing THREE
TIMES FASTER than that of the PERMEATE water ow coming out of the RO Membrane. In this way

you achieve a 3:1 ratio where 3 parts is BRINE water and 1 part is PERMEATE water. (You can do this by
judging the ow visually or see the note below for how to do a timed measurement.)
When you are condent that you have properly set the ow ratios as explained above, locate the
“marker sleeve” which is found directly under the top dial of E–Z Flush Flow Restrictor. Screw this
marker sleeve down the threads of the shaft of the dial so that it is ush with the main body of the E–Z
Flush Flow Restrictor. This will serve as an exacting marker to the amount of ow restriction you have
set. Now turn the Manual Shut-O Valve back to its (OFF) position and remove the blue tubing from
the E–Z Flush Flow Restrictor.
PLEASE NOTE: The 3:1 ratio depicted above can
easily be achieved by visually judging the rate of the
BRINE / PERMEATE ows. However if you want to
achieve exacting ratios between brine and permeate
water you can simply time how long it takes to ll a
certain volume such as a measuring cup or the like
(Fig 13). When doing this“timed measurement” the
permeate water should take three times as long to ll
the same volume over that of the brine water (3:1 Ra-
tio). We do not recommend anything over a 1:1 ratio
as it is extremely important for the R.O. Membrane to
have adequate BRINE ow to be able to ush away the harmful particulates it is removing while lter-
ing the water. A setting near to or at 1:1 ratio is only recommended if you are in a desert environment
and need to conserve as much water as possible or if you are charged large sums of money per gallon
from your water utility. A RATIO BEYOND 1:1 IS VERY LIKELY TO DAMAGE THE R.O. MEMBRANE. YOU
SHOULD ALWAYS HAVE MORE BRINE WATER FLOW THEN PERMEATE WATER FLOW.
For your convenience this system is fully automatic! When you draw water from the Aquasafe faucet,
the system will auto-ll its holding tank and then shut o until more water is drawn from the sys-
tem where the cycle would then repeat. This means that you will always have an abundance of pure,
healthy, alkaline water on tap at any given time you desire.

‘PERMEATE’ water

The permeate water coming directly out of the R.O. Membrane housing (via the auto shut-o valve)
should achieve an 85% or greater reduction in ppm (parts per million) from that of your unltered
cold tap water in your home that has not been ltered by this system. If a TDS Meter was ordered
with your system gather a few ounces of water in a small glass and test the ppm’s - comparing the
ppm count of the permeate water coming directly out of your R.O. Membrane against that of your
home’s unltered cold water. It may take up to 15-20 minutes for the RO Membrane to become fully
activated and ushed of its food grade preservative to achieve this minimum 85% ppm reduction
Example: Home’s unltered tap water is 300ppm / R.O. Permeate water should be 45ppm or less.
You can nd this value for your results by multiplying them by 0.15 (the 15% of particulates that are
left when 85% have been removed). If you do not see the minimum of 85% reduction in ppm’s after
20 minutes of permeate water ow, it means your R.O. Membrane is not seated properly in the R.O.
Membrane housing. You will need to take the R.O. Membrane out and re-insert as rmly as possible,
reassemble and then re-test the ppm’s as depicted above. If you do need to re-seat your R.O. Mem-
brane it is a very quick and easy procedure. Testing the ppm reduction rate of the permeate water
coming directly out of the R.O. Membrane housing is the most important ppm reduction test
you can perform and is a sure way to know if your system is performing as it should.
NOTE: You can also test the ppm of the water after the D.I. Resin Canister and the ppm here
should be even lower than that coming out of the R.O. Membrane.
