GETTING STARTED
Thank you for purchasing this quality water purification
system by Aquathin Corporation. The Aquathin Platinum
90 and PSS 90 are the ultimate sophisticated state of the
art in water purification and began production in the early
1990's after successful lab testing and 20 year field
experience of the Aquathin Platinum 90 and our original
Aquathin manual flush PSS90, both of which are still in
production and used by Dealers and Consumers around
the world. This user’s manual serves for the installation
of both Platinum 90 and the PSS 90 models. Every
Aquathin Series system combines several efficient
methods of water treatment to achieve a very specific
result—pure water that meets the rigorous standards for
biocompatibility.
As the new owner of an Aquathin RO/DI water
purification system there is a totally new experience
awaiting you. You and your family will be amazed at the
delightful new taste of your tap water—it’s like owning
your own personal mountain spring.
This manual provides information about the application
and servicing of your Aquathin water purification system.
Descriptions of the components and their functions will
help to answer frequently asked questions. By thoroughly

reading this manual you will be better able to operate
your new system and perform simple maintenance.
SETTING UP YOUR SYSTEM
Your Aquathin system requires adequate water pressure.
The system operates at 24 volts, utilizing a compact
transformer that accommodates either 110 or 220 volts,
so that you can take your system wherever you move.
This unit is designed to operate within a pressure range of
40–100 PSI. The amount of purified water produced
depends primarily on your water pressure, temperature,
and the amount of Total Dissolved Solids (TDS). Normal
production averages up to 45 gallons (≈ 170 liters) per
day. If you plan to install this unit on a private well
system, you should check your water pressure gauge. If
the low pressure setting is less than 40 PSI, ask a plumber
to adjust and raise the pressure to the minimum level of
40 PSI. An optional booster pump (PBA-G) is available
when source pressure is severally low. Installation to
comply with state and local laws and regulations.
IMPORTANT NOTE:
For private well owners we recommend that you choose
the Aquathin RO/DI water purification system with a
PBA-G booster pump system which includes a booster
pump and is completely configured at the factory. This
eliminates fluctuations in line or low pressure associated
with private wells and ensures your system operates at
peak efficiency. While 45PSI is enough to produce water
with exceptional purity required for passing Aquathin
standards, you may find water flow to the faucet is less
than optimal, and that your holding tank will not store
much water. (The amount of water stored is a function of
line pressure).

plumbing practice to drill
a 7/8" hole in the sink.
Porcelain sinks: factory
approved method is: first
grind away porcelain
with a Dremmel® tool
and silicon grinding
wheel (about ¾" circle).
Then, use a standard ½" high-speed drill bit to drill hole
through metal portion of sink. (insert figures) Alternately,
use a “glass and tile carbide spade tipped bit.”
Acrylic sinks: use ½" high-speed drill bit.
Stainless Steel sinks: use ½" high-speed drill bit or ½"
Greenlee chassis punch.
3) Install faucet according to detailed diagram in
Appendix C1. page 47, insuring rubber gaskets are in
place.
4) Tighten lock nut beneath sink. Save compression
fitting parts for connection to GAC post-filter.
5. Installing the
Feed Water Saddle
Valve

Turn off the cold water valve under the sink or the
main valve for the house. Slide clamp over the copper
tubing and tighten screw firmly to hold the clamp in
position. Pierce the copper tubing by turning the
needle valve handle clockwise until it is firmly seated.
The valve is closed in this position. Turn on the MAIN
supply valve to pressurize cold water line.
Immediately check for any signs of leaks. Set aside
compression fittings for later use in connecting feed
tubing to system.
When ready to supply water to the system, turn valve
handle counter-clockwise until fully open. In some
instances the self-piercing valve provided will not be
compatible with your plumbing. We have provided a
feed valve that will satisfy most scenarios. Alternate
parts using standard ¼" compression fittings can be
found at a plumbing supply or at home improvement
stores. On rare occasions, it may be necessary to
contact a plumbing contractor to complete your
installation.
6. Installing the Drain Saddle Valve
The drain
s a d d l e
a s s e m b l y
should be
i n s t a l l e d
above the trap
and on the
vertical or
h o r i z o n t a l
tailpiece. (See
Figure 5).

Install the screws (Figure 8) provided allowing for the
thickness of the frame. (A pilot hole using a 1⁄16" drill bit
is recommended for particle board side-walls.)
NOTE: Do not hang the assembly until tubing
connections have been made (following pages.)
8. Making the Tubing Connections
You have completed the bulk of the installation tasks. All
that remains is connecting tubing between the
components.
The tubing is to be used to:
 Connect the feed water saddle valve to the inlet on
the main assembly (indicated by “TO FEED”)
 Connect the chrome faucet to the inlet on the main
assembly frame (indicated by “TO DRAIN”)
 Connect the tank to the inlet on the main assembly
(indicated by “TO TANK”) and as well to connect
the tank to the faucet through the GAC post filter
(CARB 6).
NOTE: It is important to correctly measure the required
length of the tubing for each connection prior to cutting
the tubing. Additional yellow and red tubing are provided
if you opted for the pump (PBA-G).

9. Connecting Tubing to John Guest Speedfit®
Fittings
Aquathin systems make extensive use of John Guest
Speedfit® fittings. These high quality components
provide secure, leak free seals and make it easy to
connect and disconnect tubing without the use of tools.
Refer to diagrams on page 48, Appendix C2.
10. Connect Cold Water Supply Line
Measure and cut a
length of tubing to
connect the feed water
saddle valve to the left
inlet on the frame
assembly (indicated
by “TO FEED”).
Connect the tubing to
the saddle valve using
th e co mp r essio n
fittings provided. (See
f i g u r e 9 a n d
installation diagram
on page 49.)
Cut tubing so the end
is square to ensure a
leak free seal. Cut
tubing with a fresh,
sharp blade and a
slicing motion to
avoid crimping. See
figure 10 on the right.

11. Connect the Drain Line
Measure and cut a length of tubing to connect the drain
water check valve (indicated by “TO DRAIN” on the
frame assembly) to the drain water saddle valve.
IMPORTANT: Be sure to measure the tubing
appropriately before cutting. If the frame of the main
assembly is not above the drain saddle valve, you will
need to loop the tubing as high as possible beneath the
sink. Be sure to allow for this loop when you measure. A
self-adhesive tubing clip has been provided to secure the
drain loop.
12. Mount the Main Assembly
With the cold water supply and drain line connected, the
main assembly can now be placed onto the screws
previously installed. Place the keyhole openings over the
screws then slide the frame horizontally onto the
mounting screws. You may wish to remove the main
assembly and adjust the screws to make the connection as
secure as possible.

13. Prepare Storage Tank
Remove the plug
on top of the
storage tank,
revealing an inlet.
Wrap Teflon pipe
tape on the
threads of the
storage tank inlet;
then place three
(3) drops of
regular household
chlorine bleach
into the opening.
Attach the tank
ball valve as shown in the figure above. Close valve to
prevent chlorine from escaping.
Close the tank ball valve by turning the blue handle
perpendicular to the valve body; then screw the valve
onto the storage tank until firm. DO NOT OVER-
TIGHTEN. Determine the position for the storage tank
beneath the sink. If space is at a premium, it is OK to lay
the tank on its side. A stand is included.
14. Connect Main
Assembly to Storage
Tank
With the tank in position,
measure and cut a length of
tubing to connect the inlet
of the main assembly
indicated by “TO TANK”
and the “T” connector on
the tank ball valve. (See
figure 13.)
Figure 12. Storage tank preparation
Figure 13. Main assembly

18 © 2007-2016 Aquathin Corporation. All rights reserved.
15. Connect GAC Post Filter
Refer again to the installation diagram on page 49 in
Appendix C3. The GAC post-filter (CARB 6) is
typically installed just below the faucet assembly and is
easily supported by the tubing and Speedfit® fittings.
Measure and cut a length of tubing to connect the outlet
of the GAC post-filter to the faucet assembly. Placing the
post-filter near the tank will make it easy to service when
needed.
Connect one end of the tubing to the threaded stem of the
chrome faucet assembly using the ¼" compression
fittings provided. (See diagram on page 49 in Appendix
C3.)
Connect the opposite end of the tubing to the outlet of the
GAC post-filter.
Finally, measure a length of tubing to connect the storage
tank to the GAC post-filter.
Leave the handle on
the tank ball valve
closed at this point.
16. Power-up the
Main Assembly
Connect the provided
transformer to the main
assembly as shown.
17. Connect to Ice Maker –optional
Before connecting the GAC post-filter to the faucet
assembly (as described above), connect the GAC post-

(PBA-G)
I f y o u e x p e r i e n c e
fluctuations in line or low pressure, often associated with
private wells, we recommend that you choose the
Aquathin RO/DI with PBA-G booster pump system
which includes a booster pump and is completely
configured at the factory. (The amount of water stored is
a function of line pressure). To setup and install the
optional pump, refer to instructions in Appendix D.
VERIFY THE TUBING AND THE FLOW
Tubing and flow depend on whether you chose to use the
pump.
Without pump:
Cold water enters the main assembly through the “TO
FEED” inlet. The water then passes through to the inlet
of the CARB 12 pre-filter and from the pre-filter to the
RO Module.
The purified water exits the main assembly from the “TO
TANK” outlet and passes through the tank and the
CARB 6 GAC post-filter before reaching the chrome
faucet.
With pump:
Cold water enters the main assembly through the “TO
FEED” inlet. The water then passes through the pump to

Congratulations! You have completed the installation of
your Aquathin water purification system. You are now
ready to begin making pure, Aquathin quality drinking
water.
STARTING YOUR SYSTEM
1. Open the chrome faucet on the sink top.
2. Verify the Tank Ball Valve is closed.
3. Slowly open your cold water supply valve. You will
also begin to hear water flowing into the drain.
4. Check the pressure gauge on optional PBA-G.
Record your initial pressure in Appendix B.
5. In approximately 20 minutes you will begin to see
water drip from the faucet.
6. Close the faucet on the sink top, and then quickly
open the Tank Ball Valve to allow the storage tank to
fill. Actual production rate will vary slightly
depending on pressure, but your system will normally
produce up to 45 gallons of water per day, depending
on model. The first tank of water may take longer.
7. DISCARD THE FIRST FULL TANK OF
WATER. Open the faucet and let the water flow
until only a trickle remains. Close the faucet and
allow the tank to fill a second time. You are now
ready to enjoy the great taste of 100% pure, Aquathin
drinking water. (The RO Module contains a
preservative solution that will be flushed after the
first tank of water is produced.)
