If you have added components to your Salt-Free Water Conditioner,
note the correct sequencing below.
(Installation shown below includes Professional Grade Install Kit)
Before installing
• Lay out system in appropriate conguration. Improper sequence
of equipment will aect performance, and could possibly damage
your system.
• For all installations: 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 stores or
through your plumbing contractor). Due to the varieties of home design,
not all congurations can be addressed in this guide.
• DO NOT install this water conditioner where the line pressure may
exceed 100 psi. The operating pressure range for this lter is between
20psi – 100psi.
• Install on cold water lines only (40° – 90°F).
• Installation of the water conditioner must comply with existing state and
local plumbing codes. Aquasana and its manufacturer are not liable for
consequential or incidental damages due to improper installation.
• DO NOT install the unit on its side. It must be installed upright
to maximize contact with media bed.

USE & CARE 3
Read all precautions and installation instructions carefully and completely
before installing.
Precautions
• Properly tighten all ttings to
ensure a leak-free assembly.
• 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.
• Pick an appropriate installation
location. Dimensions of systems
vary—always allow an estimated
minimum of 60” clearance for
height of tank, and a minimum
of 45” for oor space.
• 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.
• It is recommended your system
be installed indoors and out of
direct sunlight. Prolonged
exposure to light can weaken
plastic components, resulting in
lter 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.
• If installing on metallic plumbing,
two grounding clamps and #4
copper wire are essential for safety.
• Some local codes may require
the use of a licensed plumber or
certied installer when disrupting
a potable water line.
• In areas with high pressure, a
pressure relief valve and a water
hammer arrestor may be necessary.
Cleaning
The exterior of your water conditioner
can be cleaned with warm, soapy
water. Rinse well with fresh, clean
water.
A Pre-Filter is included with your
system. Sediment levels vary from one
location to another. It is recommended
to replace your Pre-Filter every 2
months. If the ow rate has noticeably
decreased, replace your lter cartridge
sooner.
Specications
This water conditioner is designed and
tested for use with genuine Aquasana
parts including replacement lters and
all hardware. Use of parts from other
manufacturers may result in loss of
contaminant reduction performance,
system damage or failure. Use of parts
from other manufacturers will also
void your warranty. Please visit
aquasana.com for replacement parts.
Model: EQ-AST-WH / EQ-AST-WH-C
Replacement tank:
EQ-AST-WH-R / EQ-AST-WH-C-R
Additional Replacements:
20" Pre-Filter: EQ-304-20
10" Pre Filter: EQ-304
10" Post-Filter: EQ-PFC.35

NOTE: Never use chemical
cleaning products on the system’s

damage the housing.

1. Once out of the box, keep the tank upright
at all times as to not apply pressure to
divider. Remove shipping caps from inlet
and outlet ports. Using supplied adapter,
connect a garden hose to the inlet port
so the water will ow into the system
and out of the outlet port.
2. Slowly turn faucet on and allow
discolored water to ow from
outlet into a suitable
drainage area.
TIP: You may need to slightly shake
the tank to help ush the system.
3. Flush the tank for 5-10 minutes.
4. Disconnect the system from the garden
hose, be sure the white washers are
properly set inside the inlet and outlet
ports, and position the system
for installation.

Pre-Condition Salt-Free Water Conditioner
Select Location
1. Pick an appropriate installation location. Unit must be installed in an
area where the main water line enters your home, before connecting
to the water heater.
2. Turn o the main water source prior to installation. Drain water from
lines to relieve pressure by turning on a faucet inside your home.
NOTE: DO NOT install after the water heater or on the
hot water line. Components and installation will vary.
NOTE: It’s imperative that this system is ushed properly prior to nal installation.

INSTALLATION STEPS

5
Prepare Salt-Free Water Conditioner
Wrap your pipe nipples with NSF
certied plumber's tape. Connect the
nipples to the system's inlet and outlet.
NOTE: DO NOT use pipe solvent
(dope), as solvents in some types
of pipe dope may cause damage to
plastic ttings. Do not over-tighten
to prevent damage to lter head.
3
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.

Cut Pipes
Cut pipe along the marked sections from step
5 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 tubing or PVC.
INSTALLATION STEPS
NOTE: DO NOT cut more pipe than necessary. You can cut more pipe
later if needed. If you're also installing a Pro-Install Kit or bypass loop,
do so at this time.

Install Shut-o Valve and Ensure Spacing
1. Using a pipe cutter, cut into the main water supply line to install
the shut-o valve.
2. Loosely t shut-o valve to calculate proper spacing of components.
3. Measure distance for Pre-Filter, Salt-Free Water Conditioner tank,
and optional add-ons (Rhino Tank, Post-Filter, and UV) and mark
pipe accordingly.
If you're installing additional add-ons make sure to read through
those separate installation manuals prior to fully installing your
complete system.

Ensure proper spacing to t Pre-Filter, Salt-Free Water Conditioner,
and any optional add-ons
CORRECT
INCORRECT

Congure System
Fit Salt-Free Water Conditioner tank and additional optional add-ons
into the system at this time. Screw Pre-Filter support bracket onto
the wall and attach Pre-Filter.
Properly connect system together accordingly (slip ttings, barbed
ttings, NSF certied PVC glue, etc.). Ensure all parts are owing
through the "IN" port in the correct direction of water ow.
Final System Check
Once installation is complete, allow proper time for glue to dry
according to manufacturer instructions. Then, slowly turn water
on and inspect for leaks.
After inspecting for leaks, turn on the faucet closest to the
installed unit and allow water to run for 5-10 minutes for the
nal ushing period.
