Precautions
• For all installations: Due to the varieties of home design, not all
congurations can be addressed in this guide. Anticipate the need for
additional parts and pieces including but not limited to pex tubing, clamps,
and mounting screws to install unit properly (available at a local home
improvement store or through your plumbing contractor).
• DO NOT install this conditioner where the line pressure may exceed 100 psi.
The operating pressure range for this lter is between 20psi – 100psi. In areas
with high pressure, a pressure relief valve and a water hammer arrestor
may be necessary.
• Install on cold water lines only (40° – 90°F).
• Installation of the system must comply with existing state and local plumbing
codes. 
• Some local codes may require the use of a licensed plumber or certied
installer when disrupting a potable water line.
• It is recommended your system be installed indoors and out of direct
sunlight. Prolonged exposure to light can weaken plastic components, resulting
in housing failure. If this is not possible and the system is outdoors or
in a sunny area, the unit must be protected from both direct sunlight and
freezing temperatures.
• Unit must be installed in an area where the main water line enters your home,
before connecting to the water heater. DO NOT install after a water heater or
on the hot water line.
INSTALLATION STEPS

< Back To Table of Contents Next >
Precautions (continued)
• DO NOT install the tank on its side. It must be installed upright to maximize
contact with media bed.
• Pick an appropriate installation location where if the tank or any connection
thereto should leak, the resulting ow of water will not cause damage to
the surrounding area. Dimensions of systems vary—always allow an estimated
minimum of 46” clearance for height of the Standard Salt-Free Water
Conditioner tank, an estimated minimum of 57" clearance for height of Tall
Salt-Free Water Conditioner tank, and a minimum of 44” for oor space.
• Conditioner tank must be ushed before running water from system into
house.
• NSF certied plumber's tape (thread sealing tape) is the only sealer that
can be used on threaded ttings. DO NOT use pipe dope or PVC primer/glue
on threaded ttings. Exposure to these compounds will damage nipples
causing leaks.
• Properly tighten all ttings to ensure a leak-free assembly.
• If installing on metallic plumbing, two grounding clamps and #4 copper wire
are essential for safety.
• It is strongly recommended to install a check valve at the end of your system
conguration and before the water heater to protect your system from back
ow.

Select Location
Lay out system in appropriate conguration. Improper sequencing
of equipment will aect performance, and could possibly
damage your system.
1. Pick an appropriate installation location. Unit must be installed in an area
where the main water line enters your home, and before it connects to the
water heater. It is recommended to install after any outdoor hose bibs or
irrigation lines to avoid using conditioned water where not needed.
2. Choose the location for a shut-o valve to be able to isolate your system. If
installing a check valve, it should be installed after your system but before
the water heater.

DO NOT install after the water heater or on the hot water line.

Prepare Salt-Free Water Conditioner
1. Ensure the Salt-Free Water Conditioner tank sits level. If it looks o-
center or unlevel, reference the troubleshooting section.
2. Pre-assemble all parts and dry-t the entire system to ensure proper
spacing and to conrm you have the necessary components for
installation. Reference system conguration image on page 3 to
understand the system layout and connections.
3. Connect all smooth tting connections using NSF certied primer and
glue. Smooth connections will be on the nipples, unions,shut-o valve,
and PVC tee. Once glue is applied, press and hold the connection tight
for 10-15 seconds.
4. Carefully remove shipping caps from inlet
and outlet ports without damaging valve threads.
5. Wrap threaded nipple ends 3 times with NSF certied
plumber's tape. Insert the nipples and attached
unions to the ltration tank's threaded inlet
and outlet. Hand tighten and then tighten
again with a pipe wrench (2-2.5 rotations)
to seal the connections.
2
NOTE: DO NOT OVER-TIGHTEN. If space
does not allow for a pipe wrench to grip
the nipples, clamp to the glued union to
make nal rotations.

Install Shut-o Valve and Ensure Spacing
1. Turn o the main water source. Drain water from lines to relieve
pressure by turning on a faucet at the lowest elevation inside your home.
2. Using a pipe cutter, cut into the main water supply line and catch any
remaining water in the 5-gallon bucket. Each system includes a 1" PVC
shut-o valve with the option of threaded or smooth connections,
as well as reducer bushings to connect to a 3/4" main water line.
3. Loosely t shut-o valve to calculate the proper spacing of components.
4. Measure distance for Pre- and Post-Filter, and optional add-ons and mark
pipe accordingly.

NOTE: You may need additional components to connect your system to the
main water line where it enters and exits the system. Ensure you have all
components needed before proceeding to the next steps.
When installing on metallic
plumbing, ensure you take the
following precautions. Securely
install two (2) grounding clamps
and a #4 copper wire (not
included) across the location
where the system will be installed.
Tightly clamp at both ends, as
shown in the illustration.

NOTE: Installation could take 1–4 hours to complete. Plan accordingly as you
will be without water throughout the home during this time.
ELECTRICAL SHOCK HAZARD
Prior to installation on metallic plumbing, securely install two grounding clamps and
a #4 copper wire per installation instructions. Failure to follow these instructions can
result in death or electric shock.
WARNING

NOTE: DO NOT cut more pipe than necessary. You can cut more pipe
later if needed.

Cut Pipes
Cut pipe along the marked sections from
step 4 and clean ends of pipe. Ensure there
are no burrs, sharp edges, or deep scratches.

NOTE: Cut tubing as straight as possible with a utility knife, or an appropriate
pipe cutter for copper, PVC, or PEX tubing.

6Congure System
1. Fit Salt-Free Water Conditioner tank and additional optional add-ons
into the system at this time.
2. Attach the shut-o valve to your incoming water line.
3. Connect the threaded nipple from the shut-o valve outlet to the
20" Pre-Filter housing inlet with NSF certied plumber's tape.
4. Attach the lter wall bracket to the Pre-Filter housing with included screws.
Once this is complete, screw the support bracket to the wall.
5. Ensure all parts are owing through the "IN" port in the correct direction of
water ow.
6. Connect the threaded nipple from the Pre-Filter outlet to the union that is
attached to the Salt-Free Water Conditioner tank inlet.
7. Connect drain valve into 1/2" threaded PVC tee with plumber's tape.
8. Connect the PVC tee to the union attached to the Salt-Free Water Conditioner
tank outlet as well as the Post-Filter inlet with included nipples.
9. Attach the Post-Filter bracket and housing to the wall, similar to the
Pre-Filter, and ensure all connections are tight.
10. If you have additional attachments, please reference those manuals before
the nal installation.
11. Once installation is complete, allow proper time for the glue to dry according
to manufacturer instructions.
NOTE: Additional materials may be needed to ensure Pre-Filter and Post-Filter
brackets are supported and properly secured to wall.

INSTALLATION STEPS 10
< Back To Table of Contents Next >
1. Connect a garden hose to the integrated drain valve and ensure the
drain valve is in the open position.
2. Ensure the garden hose outlet is directed towards a oor drain or
outdoor area.
3. Slowly turn the water on from the initial shut-o valve and inspect for leaks.
If any leaks are detected, refer to the troubleshooting section.
If no leaks are detected, proceed with the ushing process.
4. Slowly turn the water on and allow discolored water to ow from the drain
valve into a suitable drainage area.
Flush Your System
NOTE: It’s imperative that this system is ushed properly prior to system
water entering your house.
