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 lter 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 ltration system 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.

2USE & 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 ltration
system 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 lter system 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.

Pre-Condition Rhino Tank
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.
The granular carbon used in the bottom tank contains 1-2% by volume of carbon
nes that must be ushed out prior to use. Surge ushing is the best method for
purging these carbon nes from the media bed.

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. The rst few gallons will
appear black and cloudy due to
carbon nes.
TIP: You may need to slightly shake
the tank to help remove carbon nes.
3. After an initial 15-minute ushing, begin
a period of “surge ushing” by turning water
supply on for 30 seconds and then o for 30
seconds, repeating cycle for 15 minutes or
until initial surge of water is completely clear
and free from discoloration and cloudiness.
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.
INSTALLATION STEPS

INSTALLATION STEPS
Prepare Rhino Tank
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.

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, Rhino tank, and optional add-ons
(Salt-Free Conditioner 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.

Congure System
Fit Rhino tank and additional optional
add-ons into the system at this time.
Screw Pre-Filter and Post-Filter support
brackets onto the wall and attach lters.
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.

RHINO®WATER FILTER
LIMITED WARRANTY
Who is covered
AQUASANA AND ITS SUPPLIERS, (herein collectively referred to as “Manufacturer”) warrants to the
owner of the home where the water lter is initially installed (hereinafter “Owner”). The warranty is
restricted to the water lter used in a single-family residence in the United States of America and is
void if moved from the original installation location.
What is covered
This Warranty covers defects in materials or workmanship during the limited warranty period of
your Aquasana Rhino Whole House Filtration System including sub-components purchased with
original system (may or may not include pre-lter, post-lter, and ttings), except as provided below.
The water lter is warranted only when it is installed, operated and maintained in accordance with
the instructions accompanying the water lter found on Aquasana.com. A water lter should be
installed in such a manner that, if the tank or any connection thereto should leak, the resulting ow
of water will not cause damage to the area in which it is installed. For detailed instructions read the
manual accompanying the water lter and review drawings in the manual.
For how long
This warranty runs for months specied in chart below from the date of purchase by a consumer
(herinafter "Warranty Period"). No warranty coverage will be provided if the claimant is unable to
provide proof of purchase. Water conditions and use rates may limit the functional lifespan of your
lter. This Limited Warranty does not extend to the full estimated life span of the lter.
What Aquasana will do
1. If necessary, the Manufacturer will provide a replacement that fullls the remaining estimated
lifespan/capacity (see chart) of your original purchase and send it to you with installation
instructions. If industry standards, product improvements or product obsolescence prohibit
Manufacturer from furnishing an identical model replacement water lter under this warranty,
the Owner will be furnished with a new water lter of comparable remaining capacity and
functionality; however, the Owner will be charged for the additional value of the item(s) which
Manufacturer has incorporated in the replacement water lter.
