PRECAUTIONS AND MAINTENANCE
Precautions
• Do not install this filter where the
line pressure may exceed 100 psi. The
operating pressure range for this filter
is between 20psi – 100psi.
• Install on cold water lines only
(40° – 90°F). Protect unit
from freezing.
• 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.
• Do not install the unit on its side. It
must be installed upright to maximize
contact with media bed.
• It is recommended your system be
installed inside and out of direct
sunlight. 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.
• Installation of the filter must comply
with existing state and local plumbing
codes. A. O. Smith is not liable for
consequential or incidental damages
due to improper installation.
• Improper sequence of equipment will
affect performance, and could possibly
damage your system.

Read all precautions and installation
instructions carefully and completely
before installing
The exterior of your filtration system
can be cleaned with warm, soapy water.
Rinse well with fresh, clean water. Never
use chemical cleaning products on the
system’s exterior surface as they may
damage the housing.
A sediment pre-filter for your system
is recommended. Sediment levels vary
from one location to another. If the flow
rate has noticably decreased, a pre-filter
to remove the sediment is usually the
root cause. If you have a pre-filter, once
the flow rate has noticeably decreased
it is time to replace the filter. Allowing
sediment to collect continuously can
cause clogging and restrict the flow of
water into your home. We recommend
replacing your sediment pre-filter
cartridge every 2-3 months.

1 Using supplied adapter, connect a garden hose to the inlet port so
the water will flow into the system and out of the outlet port.
2 Slowly turn faucet on and allow discolored water to flow from
outlet into a suitable drainage area. The first few gallons will
appear black and cloudy due to carbon fines.
3After an initial 15-minute flushing, begin a period of “surge flushing”
by turning water supply on for 30 seconds and then off 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 and position
it for final installation.
IMPORTANT Keep the unit in an upright
position at all times.
Remove red shipping caps
from the inlet and outlet
ports on the main housing.
1
Pre-condition the unit by surge flushing. It’s imperative that this system is flushed
properly prior to final installation. The granular carbon medium used in the bottom
tank contains 1-2% by volume of carbon fines that must be flushed out prior to use.
Surge flushing is the best method for purging these carbon fines from the media bed.
2
IMPORTANT
The inlet piping assembly must be firmly braced and supported.
Do not over-tighten fittings, as this may cause leakage and broken fittings. Do NOT use
pipe dope. The use of pipe dope voids the warranty. You may use NSF-certified pipe
primer, glue and plumber’s tape. Leave 2 or 3 threads exposed and do not exceed seven
layers of plumber’s tape. More than seven layers will cause the nipple to crack and leak.
Turn off the main water
source prior to installation.
3
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. DO
NOT install after the water heater or
on the hot water line. Components
and installation will vary.
4Once installation is complete, slowly
turn water on and inspect for leaks.
5
Once the unit is installed and checked
for leaks, turn on the faucet closest
to the installed unit and allow water
to run for 5-10 minutes for the final
flushing period.
