GETTING STARTED
Thank you for purchasing this quality water purification
system by Aquathin Corporation. Every Aquathin
AquaKING Series system combines several of most
efficient methods of water treatment to achieve a very
specific result—pure water that meets the specific result
— pure drinking and cooking water free of any and all
dangerous contaminants.
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 AQUAKING SYSTEM
Your Aquathin AquaKING system requires no
electricity—the only requirement is adequate water
pressure. This unit is designed to operate within a
pressure range of 40–100 PSI (3.1-6.9 bar). The amount
of purified water produced depends primarily on your

8 © 2009 Aquathin Corporation. All rights reserved.
water pressure, temperature, and the amount of Total
Dissolved Solids (TDS). Normal production averages up
to 45 gallons (~170 ltr) 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-AK) 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 AK40 with PBA-AK 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
AquaKING system operates at peak efficiency.
While 45PSI is enough to produce water with the
exceptional purity required to pass 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).
Installing Your AquaKING System Requires the
Following Steps:
• Install the sink-mounted chrome faucet.
• Install the feed water saddle valve to deliver tap
water to your system.
• Install the drain saddle valve so contaminants can be
flushed down the drain.
• Mount the DI Module and Frame Assembly to the
cabinet sidewall (optional).
• Make the tubing connections.

Planning the Installation
Review the following instructions completely before
proceeding. (See installation diagram on page 48.)
Aquathin AquaKING systems are comprised of several
compact components which fit easily beneath most
kitchen sinks. We encourage you to establish the desired
location of each of the components before proceeding.
Installing the main assembly against the left sidewall is
recommended whenever possible. The storage tank has
built-in feet for upright positioning and it can be placed
on its side when space is limited. (A stand is included.)
Installing the Chrome Faucet Assembly
1)Select a location for the faucet on the sink top.
NOTE: Make sure
there are no
reinforcing ribs under
the sink drilling
location.
2)Use factory
approved method or
approved plumbing
practice to drill hole in
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. (See Figure 2, next page) 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
C–page 46, insuring
rubber gaskets are
place. Tighten lock nut
beneath sink. Save
compression fitting
parts for connection to
GAC post-filter.
Installing the Feed Water Saddle Valve
The saddle-type valve supplied is intended for use on ⅜"
to ½" copper tubing cold water supply line. It is not
intended for flex lines.
Install on cold water
line only!
1) Turn off the cold
water valve under the
sink or the main valve
for the house.
2) Slide clamp over the
copper tubing and
tighten screw firmly to
hold the clamp in
position.
3) Pierce the copper
tubing by turning the
needle valve handle clockwise until it is firmly seated.
4) 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.
5) Set aside compression fittings for later use connecting
yellow 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 plumbing supply or home
improvement stores. On rare occasions, it may be
necessary to contact a plumbing contractor to complete
your installation.
Installing the
Drain Saddle
Valve
The drain saddle
assembly should
be installed above
the trap and on
the vertical or
horizontal
tailpiece. (See
Figure 4)
Refer to Figure 5
(below right) and
follow steps 1
through 4.
NOTE: When
installing the
Main Assembly,
mount the frame
above the position
of the drain
saddle whenever
possible. (See
Figure 8 the next
page.)

Figure 5,
Mounting the Drain Saddle Valve
1) Mark hole
position, remove
the saddle
2) Drill ¼" hole
through one side.
3) Wrap Teflon tape on
threads of fitting.
4) Make sure to align
drain saddle to drilled
hole. Attach saddle to
drain pipe and tighten
the two screws evenly.

Preparing to Mount the Main Assembly
When possible we
recommend
mounting the main
assembly on the
left sidewall of the
cabinet, but this is
not a requirement.
It is not required
the system be
mounted at all—
many owners
choose to let the
main assembly
stand unsupported
on the floor of the
cabinet.
Mounting the system will make it easier to perform
periodic and annual maintenance. Allowing 15¼" from
the cabinet floor to the keyholes will allow the pre-filter
canisters to be removed without taking the main
assembly off the wall.
Install the screws 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.)
Figure 6, Minimum space needed to per-
form service without removing main assem-
bly from sidewall.
Minimum
15 ¼"

It is best to have the anodized aluminum frame placed
above the plane of the drain saddle valve whenever
possible. When this is not possible, extra care must be
taken when routing tubing from the assembly to the drain
saddle valve. (See Figure 8, above.)
Before proceeding, make sure the three pre-filter
canisters are firmly attached.
Mounting the Deionization Module (If purchased
as DIMS VS AK 40 DI complete)
The Aquathin 4 stage Deionization (DI) module can be
placed anywhere convenient inside the cabinet. Keep the
distance between the main assembly, storage tank, and DI
module as short as possible. The DI module can be
mounted horizontally (preferred) or vertically. If mounted
vertically, the outlet should be at the bottom.
If frame is below plane of
drain saddle valve, drain
tubing should be looped as
high as possible beneath sink.

1) Establish the position for the Deionization module.
If mounting above the main assembly (See Figure 6, Page
13; and Appendix C, page 46) be sure to allow adequate
space to attach the main assembly. (Allow approx. 3"
from the bottom screw of the DI mounting band to the
screws supporting the main assembly.)
2) Secure the module to the wall of the cabinet using the
supplied stainless steel clamp and screws.
MAKING THE TUBING CONNECTIONS
You have completed the bulk of the installation tasks. All
that remains is connecting tubing between the
components. Three lengths of tubing have been supplied:
6Yellow tubing to connect the feed water saddle valve
to the inlet on the main assembly.
Figure 10, Mounting the Deionization Module
Establish position for stainless
steel mounting band. You must
attach the bottom screw first.
When performing annual
maintenance only the top
screw will need to be released

6Black tubing to connect the drain saddle valve to the
drain line check valve on the right rear of the main
assembly frame.
6Blue tubing for all purified water connections: main
assembly to DI module, DI module to tank, tank to GAC
Post-filter, and Post-filter to faucet.
NOTE: When cutting the poly tubing, DO NOT USE
SCISSORS. Use a razor knife with a fresh blade. Do not
crimp or collapse the tubing. Cut the tubing with a clean,
90° angle. This will allow the tubing to seat firmly into
the fittings, creating a secure and leak free connection.
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 47, Appendix C.
Connect Cold
Water Supply to
Feed Water Inlet
Measure and cut a
length of yellow
yellow
tubing to connect the
feed water saddle
valve to the inlet on
the left side of the
frame assembly.
Connect the tubing
to the saddle valve
using the compression fittings provided.
(See Figure 11, and installation diagram on page 48.)

Connect the Drain Line
Measure and cut a
length of black
black
black
tubing to connect the
drain water check
valve on the frame
assembly to the drain
water saddle valve.
(See Figure 13, right,
and installation
diagram on page 48.)
IMPORTANT: 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. (See Figure 8 on
page 14.) A self-adhesive tubing clip has been provided
to secure the drain loop.
Cut tubing so the end is square to en-
sure a leak free seal
Cut tubing with a fresh, sharp blade
and a slicing motion to avoid crimping
Figure 12, Cut tubing square. Do not use scissors.

Connect DI Module to Main Assembly (DIMS
VS. Complete)
Measure and cut a
length of blue tubing
to connect the
reverse osmosis
(RO) water outlet on
the main assembly to
the INLET of
Deionization
module. Typically,
this tubing is routed
behind the main
assembly. Insert
tubing into fittings
and secure with red lock clips provided. (See Figures 14
& 15, and installation diagram on page 48.)
NOTE: There is an arrow indicating direction of flow on
the DI module label.
Mount the Main Assembly to Cabinet Sidewall
With the cold water
supply, drain line,
and DI module
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.

Prepare Storage Tank
Wrap Teflon pipe tape
on the threads of the
storage tank, then
place three (3) drops
of regular household
chlorine bleach into
the opening.
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. (See Figure16 .)
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.
Connect DI Module to Storage Tank
With the tank in
position, measure and
cut a length of blue
blue
blue
tubing to connect the
OUTLET of the DI
module and the “T”
connector on the tank
ball valve. (See Figure
17, right)
Wrap pipe tape on threads. Follow label
instructions to ensure disinfection be-
fore attaching tank ball valve. Close

Connect GAC Post Filter between Storage Tank
and Faucet
Refer again to the diagram on page 48 in Appendix C.
The GAC post-filter is typically installed just below the
faucet assembly and is easily supported by the tubing and
Speedfit® fittings.
Measure and cut a length of blue
blue
blue 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 blue
blue
blue tubing to the threaded stem
of the chrome faucet assembly using the ¼" compression
fittings provided. (See Figure 12 on page 17.)
Connect the opposite end of the blue
blue
blue tubing to the outlet
of the GAC post-filter.
Finally, measure a length of blue
blue
blue tubing to connect the
storage tank to the GAC post-filter.
Leave the handle on the tank ball valve closed at this
time.
Congratulations! You have completed the installation of
your Aquathin AquaKING water purification system.
