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 instructions that follow are extremely detailed.
if a leak is experienced during installation, please see the Leak
Prevention Section on page 17.
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
18) 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 easily accomplished.

2.0 Take everything out of the box
Examine the contents of the Large and Small parts bag against the diagrams 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“OUTLET” (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 blue “C” clip and then place
the blue “C” clip 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 red 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 red 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 the 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 explained 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
takes 3x longer to

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.

8.0 Installing the D.I. Resin Filter
Push two canister clips (found in the Large Parts Bag) onto the R.O. Membrane housing with the wid-
est end of the clips down (Fig. 14). Attach the D.I. Canister to the canister clips by pushing the canister
down onto the clips. Ensure the blue end caps of the D.I. Resin Canister are screwed on tightly before
doing this. The arrow on the D.I. Canister depicts the direction of ow of water through the canister.
Screw in an elbow adaptor to both ends of the D.I. Canister (Fig. 15). Remember to use teon tape
(4 to 7 wraps) on the threads of the adaptors throughout the installation as a preventative
measure against potential leaks.
Next, take the short blue hose connected to the “OUT” side of the 4 way Auto Shut-O Valve (ASV) and
push it into the elbow adaptor on the left side of the D.I. Canister.
9.0 Installing the Remineralizatin Cartridge
Push two more canister clips (found in the Large Parts Bag) onto the R.O. Membrane housing in prepa-
ration for the Remineralization Cartridge (Fig 16). You can rotate the D.I. Canister back out of the way
to make room. Remove the white plugs on either end of the Remineralization Cartridge.

Now push the Remineralization Cartridge into the canister clips (Fig. 16). The direction of the Remin-
eralization Cartridge is important. THE TEXT SHOULD NOT BE UPSIDE DOWN. The arrow on the lter
indicates the direction of water ow. Take an elbow adaptor from the Small Parts Bag and screw it into
the right side of the Remineralization Cartridge. Then take last elbow adaptor from the small parts bag
and screw it into the left side of the Cartridge (Fig 16) Remember to apply 4-7 wraps of Teon tape.
Take a 4 inch piece of blue tubing from
the Small Parts Bag and insert one end
of the 4 inch blue tube to the elbow
adaptor on the right side of the Remin-
eralization Cartridge and the other end
to the elbow adaptor on the right side
of the D.I. Canister (Fig. 17).
The Remineralization Cartridge makes
pH balanced alkaline water and
releases a perfect balance of miner-
als in the form of calcium, magnesium sodium and potassium ions that can be 100% absorbed by the
human body. Because of this the ppm of the water dispensed at your Aquasafe™ faucet will be higher
than that coming out of the D.I. Canister.
10.0 Installing the Final Polishing Filter
Push the two remaining canister clips (found in the Large Parts Bag) onto the R.O. Membrane housing
in preparation for the Final Polishing Filter (step 1, Fig 18). You can rotate the other canisters back out
of the way to make room.
Now push the Final Polishing Filter into the canister clips (step 1, Fig. 18). The direction of the Final Pol-
ishing Filter is important. THE TEXT SHOULD BE UPSIDE DOWN so that the arrow on the lter indicates
the direction of water ow. Take the male ‘T’ adaptor from the small parts bag and screw it into the
left side of the Final Polishing Filter . Then take the straight male adaptor from the Small Parts Bag and
screw it into the right side of the Final Polishing Filter . (step 2 & 3, Fig 18) Remember to apply 4-7
wraps of Teon tape.

11.0 Prepare the R.O. Water Holding Tank
The R.O. Water Holding Tank has an air bladder and a water blad-
der inside it. The air bladder comes pre-set from the factory at 7
PSI for your convenience. CAUTION: Changes to the PSI of the
air bladder inside the R.O Water Holding tank may cause harmful
back pressure which can result in the Auto Shut-O Valve (ASV)
malfunctioning. As such, please do not attempt to adjust the air
pressure of your R.O Water Holding tank.
Please note: For your convenience, the R.O Water Holding tank
can stand up or lay horizontal to conserve space if necessary.
Screw the tank top valve found in your Small Parts Bag onto the
threads found on top of the R.O Water Holding Tank (Fig. 20).
Remember to apply 4-7 wraps of Teon tape to the thread of
the tank itself.
PLEASE NOTE: The long length of blue tubing used to ush your prelters is the tubing you will use to
hook up both the water storage tank as well as the dedicated Reverse Osmosis faucet that came with
your system.
You will need to cut this length of blue tubing in two pieces accordingly. The length of tubing used
to hook up your kitchen faucet (which will be attached to the right side of the Final Polishing Filter)

will probably need to be longer than
the length of blue tubing used to
hook up your R.O Water Holding tank
(which will be attached to the left
side of the Polishing Filter). Take a
moment and judge how much tub-
ing you will need for each purpose
based upon where the nal place-
ment of your system will be located
under your sink (or the like) and then
cut the blue tubing to length with a
sharp knife making sure your cut is
straight (not at an angle).
Now insert one end of the cut length of blue tubing (for the tank) into the male“T” adaptor found on
the left side of the Final Polishing Filter and the other end into the tank top valve connecting the hold-
ing tank to the system (Fig. 21).
12.0 Clear the Decks.
If you have not already done so, the next step is to totally clean out under your sink. Get some rags to
wipe up any water drips that may be present from the installation process. Now, step back and look at
where you want the unit and the tank positioned. Please remember, you have to service the system so
consider accessibility.
13.0 Preparing the Discharge Water Saddle Clamp.
Find a location on the drain pipe under
your sink where you wish to secure the
discharge water saddle clamp found
in your Large Parts Bag (Fig 22). Make
sure—MAKE REALLY SURE — that the
location you have chosen is above the
trap! (The trap is the “U”shaped part
of the drain pipe) You may secure the
saddle clamp on a horizontal pipe JUST
AS LONG AS YOU ARE ABOVE THE TRAP!!!
Also try to secure the saddle clamp
where it will not block anything, like
where you want to put your system or
the R.O. Water Holding Tank.
Drill out your chosen spot with a 1/4 inch
drill bit. The 1/4 inch hole that you drill into the carefully chosen location on your drain pipe is where
the yellow discharge line will be inserted into and secured into place with the discharge water line
(Drain) Saddle Clamp.
Take the gasket that came with your Large Parts Bag and remove the backing. Then stick the gasket to

the inside of the saddle clamp making sure that the yellow tubing is showing through at least 1/2 inch
(Fig. 23). Now secure the saddle clamp in its chosen location rmly making sure the tubing is inserted
into the drain pipe. You only need to tighten the bolts to the point where the gasket begins to com-
press against your drain pipe. Insert the other end of the yellow discharge line to the E- Z Flush Flow
Restrictor on the back of the unit.
14.0 Installing the Faucet.
Installing the faucet is next. You will most likely be installing the faucet through the sink top or beside
the sink top. Below are 4 dierent types of counters. Follow the instructions for your counter type. Be
aware that you can drill through your stainless steel sink but you will also have to drill through what-
ever counter material you have underneath your sink. If you have a porcelain sink, we advise against
an amateur installation. Either nd another spot (like beside the sink) or get a Pro.
a) Laminate: the most common material is a laminated counter top. Choose the most appropriate
spot on top, then crawl under and see where it clears. Remember, you have a large plastic washer
to put under the counter. The safe thing to do is to drill a pilot hole with your smallest bit rst. Then
drill a ½ inch hole and assemble the faucet (refer to diagram above). The rubber gasket goes under
the chrome faucet and the plastic washer goes under the counter. After putting the plastic washer in
place, put on the lock washer and then tighten the nut. Either have someone hold the faucet or put
a wrench on it and secure the wrench to prevent it from turning while you tighten the nut. Be careful
not to damage the faucet surface.
b) Stainless Steel: Do the same as for laminate, except be really sure of your clearance space. Take a
metal punch (or a big nail) and give the magic spot a good hit. At this indentation drill a pilot hole.
A wood drill will not do it. You must use a metal drill bit suitable for stainless. Once the pilot hole is
made, follow up with a ½” hole and attach the faucet.

c) Marble or Granite: This is not that hard, but takes some time. You need a diamond tipped drill and
about 15-20 minutes. The price of a ½” diamond tipped drill is around $75.00. Since you will probably
never use it again, you would probably be better o either renting the equipment or calling in a Pro.
Most glass installers have diamond drills and all vendors of stone have them. Some will rent it out, as
will “Rent-All”stores. Start the hole by drilling a ½” hole in a piece of scrap wood. This will serve as a
guide. Hold the piece of wood and let the diamond drill bit do the work. DO NOT push down or apply
pressure. Keep the hole lled with water and wipe out the hole often. It is important to let the weight
of the drill be the pressure and to let it just grind away at its own pace (which is slow).
d) Wood: If you have a wood counter top you could of course drill out the hole just beside the sink.
Also please keep in mind that you could run the 1/4 ” tubing to a location nearby your system.
Faucet diagram for further reference.
Follow the schematic above. Use the other length of blue tubing that was cut in two pieces during
step 11.0. When you have your Aquasafe™ faucet rmly in place in the chosen location, insert the tube
leading from the faucet into the straight male adaptor on the right side of the Final Polishing Filter.
Check over all of the steps. Make sure all of your tubing is inserted rmly into the various adaptors.
You may now turn the manual shut-o valve found on your feed water line back to its“ON” position.
Your 3.2 Gallon water storage tank will now begin lling and will take a maximum 2-3 hrs to ll to
capacity for its rst time and quicker thereafter. Once the tank has lled, empty all the water out of the
water holding tank and let rell. To empty all water from your storage tank once lled you simply need
to open your faucet until the output from the faucet turns to a fast drip or slow trickle. The RO Mem-
brane is lled with food grade preservative for quality assurance and the nal polishing lter and the
holding tank’s water bladder should be ushed out before consuming the water. Empty two full tanks
of water in order to ensure proper ushing of your entire system. After ushing two full tanks, you can
then drink and cook with the ultra puried water.

After emptying your water storage tank twice, allow your system to pressurize. Monitor closely for
potential leaks. If leaks do occur, turn the Manual Shut O Valve attached to the 4 inch piece of red
tubing found on the feed water line to its “OFF” position. The nature of water is to nd the path of
least resistance. Some initial small leaks are not unheard of. If a leak does occurs at any time please see
Aquasafe’s LEAKS PREVENTION SECTION on the page 17 of this document.
GET A GOOD FLASHLIGHT AND CHECK OVER THE ENTIRE SYSTEM CAREFULLY WHEN COMPLETED TO
SPOT ANY POTENTIAL LEAKS.
¬Congratulations on completing the installation process. You may now start drinking the ultra puri-
ed drinking water you desire for the health and enjoyment of you and your loved ones.

15.0 Extra information for the Maximus II + Remineralization COMBO
15.1 Where do I install the PSI Meter from my “COMBO” System?
If you have purchased the Maximus II System Combo, your system came
with a PSI Meter as seen in Figure 27. It is not necessary that the PSI Meter
be installed onto your system. The PSI Meter is provided as a convenience
to you as your entire system operates from water pressure. If need be, the
PSI Meter allows you to determine the water pressure at any point on your
Reverse Osmosis System which can make troubleshooting of any potential
problems on your system extremely easy. However, if you chose to install
the PSI Meter onto your system, there are two main areas where installing
the PSI Meter on your system can be of use.
Option 1. If you are on a well water system, and you think you may have
lower then 50 psi throughout your home’s plumbing, a good
place to install the PSI Meter is on the feed water line to your
Reverse Osmosis System. This will allow for easy monitoring of the source water pressure
entering your Reverse Osmosis System. Your system needs consistent pressure at 50 psi or
above. Typical well water systems will top out at 60 psi and bottom out at 40 psi. If your
pressure dips below 50 psi we highly recommend an automatic booster pump avail-
able on our website – found on the General Parts & Accessories page.
Option 2. Installing the PSI Meter on the section of white tubing coming out of the third pre-lter
housing (that attaches to the auto shut o valve) will allow you to monitor the psi of the
OUTPUT water of the 3 pre-lters. When you install new pre-lters make a note of the psi
reading at this point. Write down the PSI measurement with some permanent marker on a
piece of masking tape and stick it somewhere visible on the system. Now you can check to
see when the psi on this line drops to 15% below the initial reading you wrote down (0.85 x
initial psi reading). When this happens it is time to replace your pre-lters. You might want
to also write down on the masking tape the number you are watching for, 0.85 x initial psi
reading, to make it easier to determine the status of your system.
Figure 25

15.2 How do I use the TDS Meter from my “COMBO” System?
The TDS (Total Dissolved Solids) Meter of your system is ex-
tremely easy and intuitive to use and comes with its own set of
intructions, but here is a quick tutorial. First you will need to get
a small glass and rinse it of all dust or other particles. Now ll the
rinsed glass with the water for which you would like to deter-
mine the TDS Reading (Total Dissolved Solids). Remove the cap
from the bottom of the TDS Meter and turn on the meter. Now
simply insert the portion of the TDS Meter that was covered by
the cap into the glass of water. The number that shows on the
digital display is the ppm count (Parts Per Million) of TDS (Total
Dissolved Solids) in your water.
Note: Your TDS Meter has an auto shut o feature but try to remember to shut o the TDS Meter when
you are done testing your water to save on batteries !
15.3 How do I store my 24oz bag of extra D.I. Resin Beads?
The DI Resin should be kept airtight, away from all sunlight and at room temperature. Your 24oz bag
of extra DI Resin Beads comes sealed airtight in a black 4ml bag. Once you open the sealed black bag
of extra resin, tape the bag so that it is once again airtight and store at room temperature. Only cut o
one corner of the bag so that resealing the bag is made easy. If stored properly, the shelf life of the DI
Resin is years.
15.4 How do I store my extra case of 27 (6 changes) pre-filters, post-filters and remineraliza-
tion cartridges?
Your case of 27 pre-lters, post-lters and remineralization cartridges (6 full changes) can be stored in
the same state in which they arrived. Each lter comes wrapped in protective plastic. Store at room
temperature. Shelf life is years.

LEAK PREVENTION PAGE
ATTENTION: Before commencing any work on your system you need to depressurize your system - see Figure 27. To
repressurize your system when you are done, turn the tank top valve and the manual shut o valve back on.
Threaded Fittings
To prevent a leak on any threaded tting that screws into the Reverse
Osmosis System you simply need to employ Teon tape. The main
instructions pages indicates the preventative measure of wrapping the
threads of the various threaded ttings 4-7 times with Teon tape.
This preventative measure will ensure against any potential leaks from
the various threaded ttings throughout your Reverse Osmosis System.
ADDING SUFFICIENT TEFLON TAPE IS KEY!
If you are experiencing a leak from a 1/4 inch tube inserted into a quick connect tting, you simply need to insert the
tubing into the threaded tting further. To do this you may need a small pair of pliers to assist you in gripping the tube.
If the use of pliers is needed, grab the tubing 3/4 inch from where the tube inserts into the threaded tting in order to
not scratch the section of tube that will be inserting further into the threaded tting. A scratched section of tubing
that is inserted into a threaded tting can act as a path for water to ow, which in turn may result in a small leak.
Pre-Filter Canister Housing
All Aquasafe™ Reverse Osmosis Pre-Filter Housings are “Compres-
sion Sealed”. This means that 99% of the time any leak coming
from the threads of the Pre-Filter Housing can be easily xed by
tightening with the system’s “large Canister Wrench”. A “Large
Canister Wrench” came with the Original Purchase of your Re-
verse Osmosis System
D.I. Resin Canister
Sometimes the DI resin beads can get caught up in the threads of the
canister and in threads of the DI Canister cap. Brush away all of the DI
resin beads from the DI Canister housing and rinse out the cap. Once
the threads of the DI Resin Canister are free of all DI resin beads a leak
coming from the DI Canister can be xed by tightening the lid as much
as possible. Get a cloth to help give the grip needed for tightening
purposes. In the extremely rare case that you are still having trouble with
one end of the DI Resin Canister, you can apply a small amount of silicone (the non-hardening variety). The key to this
method is using a SMALL amount. Do not silicone both ends as you will need to change the resin beads in the future.
(Repeat the clearing of the threads a second time before you resort to this though!)

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

MAXIMUS II + REMIN SYSTEM FILTER CHANGE SCHEDULE
Pre and Post lters dened as: Pre (before the RO Membrane ) and Post (after the RO Membrane).
Stage 1,2 & 3 Pre-Filters – When to conduct a filter change.
Stages 1, 2 and 3 are your system’s pre-lters which need to be changed every 1000 gallons of puried
water produced. The average household consumes 3-5 gallons of drinking and cooking water daily. At
5 gallons per day consumption rate a lter change is needed every 6 months or sooner. Mark your
calendar for a routine lter change every 6 months to ensure system performance.
Please Note: Maintaining the pre-lters of your system is key to ensuring system integrity in both wa-
ter quality achieved and overall longevity of its parts and components. The pre-lters are your system’s
rst line of defence - protecting and ensuring the maximum lifespan of the R.O. Membrane. If you
have a PSI Meter (included with the combo system) you can also use it to determine when to change
your pre-lters (see option 2, page15).
Stage 4 – When should I change the Reverse Osmosis Membrane?
The R.O. Membrane is the very heart of your Aquasafe™ Reverse Osmosis System. The R.O. Membrane
is rated for an average of 4000-5000 Gallons of puried water production. A new R.O. Membrane will
last for approximately 3-4 years. Once again this calculation is worked out on the average as follows:
• A standard household will consume between 3-5 gallons of puried water each day for all its
drinking and cooking purposes. A 3 gallon per day consumption rate over a year’s time is equal
to roughly 1095 Gallons which therefore calls for a Reverse Osmosis Membrane change approxi-
mately once every 3.5 years.
• A 5 Gallons per day consumption rate over a years time is equal to roughly 1825 Gallons which
therefore calls for Reverse Osmosis change approximately once every 2- 2.8 Years.
If you have a TDS Meter a very simple but critical test you can perform in order to determine if your
R.O. Membrane needs to be replaced is to measure the PPM reduction rate of the puried (permeate)
water coming directly out of the R.O. Membrane housing (see Fig. 27 and 28 for how to do this).
If you are a 1 person household or a large family household it may be advantageous to monitor
approximately how many gallons of drinking and cooking water is consumed daily to factor the
proper lter change schedule for your individual situation.
• Example: Large household or oce environment consuming 8 Gallons per day.
1000 gallon pre-lter capacity / (8 GPD x 30.5 average days a month) = pre-lter change ap-
prox. every 4 months.
IF THE PREFILTERS ARE NOT CHANGED BEFORE 1000 GALLONS OF PURIFIED WATER IS
CONSUMED FROM THE SYSTEM, CHLORINE WILL BYPASS THE PREFILTERS REACHING AND
CHEMICALLY DAMAGING THE R.O. MEMBRANE RENDERING IT USELESS. It is important to
understand that even if chlorine is not present, after the 1000 gallon mark, seepage may occur
where very ne particulates will bypass the pre-lters stressing the R.O. Membrane greatly. This will
result in pre-mature fouling of the R.O. Membrane resulting in the R.O. Membrane needing to be
replaced before its due time – a costly mistake.
