The manufacturer has pre-assembled the cartridge filter tank. The actual cartridge filter is shipped separately and will need to be installed
into the tank to complete assembly.
The installer should read this complete guide to familiarize themselves with assembly, installation, and operation of the cartridge filter.
The owner should read and become familiar with the cartridge replacement change out instructions.
NOTE: Water treatment professionals and customers in the state of Iowa must complete the form below prior to sale.
The site selection for the ClearHome™ Whole-House Cartridge Filter may vary depending on the purpose it will serve. This versatile filter
may be used as pre- or post-filtration in a water treatment system. Depending on the application, this filter may also be utilized as a single
tank system.
Regardless of application, provisions should be made so that the filter is located close to a drain. A bottom drain is included for this
cartridge filter to allow rinsing of the cartridge. When replacing the cartridge, water may spill from the housing. Therefore, precautions
should be taken to prevent any damage due to water while rinsing or replacing the cartridge.
NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or
after the filter. Units certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.

The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control
valve repairs or maintenance. The 1” full flow bypass valve incorporates four positions, including a diagnostic position that allows a
service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install bypass
valve onto main control valve before beginning plumbing or make provisions in the plumbing system for a bypass. The bypass body and
rotors are glass-filled resin and the nuts and caps are glass-filled polypropylene. All seals are self-lubricating EPDM to help prevent valve
seizing after long periods of non-use. Internal “O” Rings can easily be replaced if service is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow shaped handles. The handles
identify the direction of flow. The plug valves enable the bypass valve to operate in four positions.
1. NORMAL OPERATION POSITION: The inlet and outlet handles point in the direction of flow indicated by the engraved
arrows on the control valve. Water flows through the control valve for normal operation of a water softener or filter. During the
regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution
system (Fig. 1).
2. BYPASS POSITION: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water
pressure in the plumbing system. Untreated water is supplied to the building (Fig. 2).
3. DIAGNOSTIC POSITION: The inlet handle points toward the control valve and the outlet handle points to the center of bypass
valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit from the system
to the building (Fig. 3). This allows the service technician to test the unit and perform other functions without disrupting the water
going to the building.
NOTE: The system must be rinsed before returning the bypass valve to the normal position.
4. SHUT OFF POSITION: The inlet handle points to the center of the bypass valve and the outlet handle points away from the
control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in the building.
A negative pressure in the building combined with the unit being in regeneration could cause a siphoning to the building. If water
is available on the outlet side of the unit, it is an indication of water bypassing the system (Fig. 4) (i.e. a plumbing cross-connection
somewhere in the building).

GENERAL INSTALLATION & SERVICE WARNINGS
The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments. There is a small
amount of “give” to properly connect the piping, but the filter is not designed to support the weight of the plumbing.
Do not use petroleum jelly, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be
used on black O-rings, but is not necessary. Avoid any type of lubricants, including silicone, on red or clear lip seals.
Do not use pipe dope or other sealants on threads. Plumber’s tape must be used on the threads of the 1" NPT inlet
and outlet, the brine line connection at the control valve, and on the threads for the drain line connection. Plumber’s
tape is not used on the nut connections or caps because O-ring seals are used. The nuts and caps are designed to be
unscrewed or tightened by hand or with the special plastic Service Wrench (100396829). If necessary, pliers can be used
to unscrew the nut or cap. Do not use a pipe wrench to tighten nuts or caps. Do not place screwdriver in slots on
caps and/or tap with a hammer.
SITE REQUIREMENTS
• Water Pressure: 20-120 psi
• Water Temperature: 40-100°F (4.4-43.3°C)
• Housing Dimensions: 10” diameter by 43”
height (with included fittings)
1. This unit is equipped with a 3/4” CTS push connection
(7/8” OD) at the bottom of the tank. This connection
is for a drain that may be used to rinse the cartridge
filter periodically. If this is installed, location of the
tank to the actual drain should be as close as possible.
It is highly recommended to install the optional drain
for servicing the unit.
CAUTION: If a drain is not used or
the installation makes this
unavailable, the drain hole
must be plugged or water
will flow from this outlet.
2. The housing should be installed on a firm, flat surface (above or below grade).
3. Do not install any water filter with less than 10 feet of piping between its outlet and the inlet of a water heater.
4. Do not locate unit where it or its connections (including the drain) will ever be subjected to room temperatures
under 33°F.
5. Do not subject the housing to any vacuum as this may cause an “implosion” and could result in leaking. If there is a
possibility a vacuum could occur, please make provisions for a vacuum breaker in the installation.
6. INLET/OUTLET PLUMBING: Be sure to install Bypass Valve onto main control valve before beginning plumbing. If
it is desired to bypass outside hydrants, a cold water kitchen sink, or other locations, provisions should be made
at this time. Install an inlet shutoff valve and plumb to the unit’s bypass valve inlet located at the right rear as
you face the unit. There are a variety of installation fittings available. They are listed under the Installation Fitting
Assemblies section of the manual.
When assembling the installation fitting package (inlet and outlet), connect the fitting to the plumbing system first
and then attach the nut, split ring and “O” Ring. Heat from soldering or solvent cements may damage the nut, split
ring or “O” Ring. Solder joints should be cool and solvent cements should be set before installing the nut, split ring
and “O” Ring. Avoid getting solder flux, primer, and solvent cement on any part of the “O” Rings, split rings, bypass valve
or control valve. If the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the
inlet to the outlet pipe. Plumbing must be done in accordance with all applicable local codes.
7. INSTALLING GROUND: To maintain an electrical ground in metal plumbing of a home’s
cold water piping (such as a copper plumbing system), install a ground clamp or jumper
wiring.
NOTE: If replacing an existing filter, also replace the ground clamps/wire.

8. DRAIN LINE: First, be sure that the drain can handle the rinse rate of the system. At the
bottom of the tank is a 3/4” CTS push connection (7/8” OD) to accommodate a drain. The
purpose of the drain is to manually (or automatically, if desired) rinse the filter tank and
cartridge of any debris. This can prolong the life of the cartridge. It is highly recommended
to provide a means to drain the tank and to relieve pressure for cartridge replacement.
CAUTION: If a drain is not used or the installation makes this unavailable, the
drain hole must be plugged or water will flow from this outlet.
9. DRAIN FITTING ASSEMBLY: Before inserting the pipe into the drain fitting assembly, there is a “locking cap” that needs
to be loosened. The locking cap takes the place of a traditional clip used to lock in the fitting. Follow the steps below for
proper installation:
The larger of 2
pipe diameters
or 1” air gap
required.
Installation
Step 1: Ensure locking cap is turned counterclockwise, no more than a half
rotation, until a gap of about 1/16” can be seen as shown (Fig. 1).
Step 2: Insert pipe, free of burrs and sharp edges, fully into fitting (Fig. 2).
Step 3: Turn locking cap about half a rotation clockwise until it stops and
there is no gap remaining. Turn by hand only – DO NOT use tools
and do not overtighten (Fig. 3).

1. Turn off water supply to vessel using bypass inlet and outlet lines.
See page 4 for bypass diagrams.
2. Release pressure on system by opening bottom drain for a moment, then close. If bottom
drain is not installed, turn off water to inlet side of filter and open an outlet line to the
filter.
3. Disconnect bypass from valve assembly using the nuts at the inlet and outlet head
assembly (see Fig. 1). Be careful not to disconnect the nuts at the plumbing lines as these
are under pressure.
4. Remove CT nut by rotating it counterclockwise (see Fig. 2).
CAUTION: Do not remove CT nut without relieving pressure from system.
5. Remove CT cap by pulling upward on head assembly. Cartridge will be visible.
6. Carefully remove old cartridge from system (see Fig. 3). The cartridge will contain water
and will splash or drip. Place used cartridge into 5-gallon bucket to protect area from
water damage.
7. Remove new cartridge filter from box and remove plastic covering. Locate data plate label
and keep for future use.
8. Lubricate O-ring in valve assembly to ensure proper sealing (see Fig. 4).
Do not use pipe dope, petroleum jelly, oils or other unacceptable lubricants on
O-rings. Food grade silicone lubricant is recommended.
9. Place cartridge into filter housing with “distributor riser” at top of tank (see Fig. 5).
10. Carefully replace CT cap assembly making sure that the adaptor slips into the top
cap assembly. Push down on head assembly firmly (see Fig. 6).
11. Re-attach and tighten CT nut by turning it clockwise.
12. Adhere data plate label to tank under CT nut for future reference, but only when
supplied with certified filter cartridges (see Fig. 7).
13. Reconnect cartridge tank to bypass valve by securing nuts.
14. Open treated water line and turn bypass valve to service position
(Fig. 1 on page 4) and allow water to fill tank slowly. Once water is flowing to
treated water faucet, observe tank for any leaks.
15. Shut treated water line off to check for leaks and ensure system integrity.

CONTAMINANT REDUCTION SYSTEM REQUIREMENTS
In order to qualify as a “certified” contaminant reduction system, a water treatment system must meet the requirements
set forth on the proceeding pages. A. O. Smith has certified the individual components of the system outlined below. To
complete the system, the installing dealer must follow some simple guidelines.
•Proper Installation of an accompanying, qualifying certified softener or backwashing filter equipped with a
service alarm. In a contaminant reduction system, this unit is referred to as a Performance Indicating Device
(PID). A PID must be able to meter the amount of water flowing through the unit as well as alarm once
the capacity of the unit has been reached (See the service alarm section for more details). On A. O. Smith
controllers, the term “Service Alarm” has been used in lieu of “Performance Indicating Device”. Both terms refer
to the same component in a contaminant reduction system and are used interchangeably.
•If a PID (service alarm) is not installed on the accompanying equipment, the CT-05-CB-AMCY-IO cartridge is only
certified to 45,196 gallons. It will be required to change out the cartridge more frequently.
•Proper installation of the ClearHome cartridge tank in which the contaminant reduction cartridge filter
(cartridge filter model No. CT-05-CB-AMCYL-IO) is installed into.
•Proper setting of the service alarm (PID).
•Proper labeling of the cartridge tank.
PERFORMANCE INDICATING DEVICE (PID)
To qualify as a certified contaminant reduction system to 75,327 gallons, the ClearHome cartridge tank must be installed
with a contaminant reduction cartridge and a PID. This device is used to notify the user of cartridge life and to signal
when a cartridge needs to be replaced.
A. O. Smith has taken additional steps and certified the meter of its softeners and backwashing filters for this use.
Any softener or backwashing filter manufactured by A. O. Smith using our 1” meter that incorporates the service
alarm feature satisfies the PID requirement of certification. This certification is specific to A. O. Smith manufactured
products and our 1” meters. Please consult A. O. Smith’s customer service department for any questions regarding this
requirement.
INSTALLATION
Installation of the ClearHome filter housing is covered on previous pages in this manual and must be installed in
conjunction with a qualifying Softener and/or Backwashing Filter. Without the qualifying softener or backwashing filter,
the system is not certified.
Installation instructions of the qualifying softener or backwashing filter is specific to those models. Refer to the
appropriate installation and service manuals included with that unit.
The ClearHome cartridge tank may be installed pre- or post-softener or backwashing filter. However, it is necessary to
make sure that all treated water through the ClearHome cartridge is metered through the PID. In municipal applications,
it is most likely that the ClearHome filter housing with a contaminant reduction cartridge will be used prior to a softener.
Please see installation diagram on following page.
NOTE: On waters that are turbid or where the quality is in question, it may be necessary to install a
pre-filter before the lead cartridge system to protect the life of the cartridge (See Contaminant
Reduction Installation Diagram). Turbidity may prematurely plug the cartridge before its 75,327
gallon contaminant reduction rating. This may cause a low pressure drop before the rated
lead capacity is achieved. Installing an additional ClearHome Cartridge Filter or a Big Blue Dual
Gradient (25 to 1 micron) sediment filter will enhance the life of the cartridge. A. O. Smith is not
responsible for decreased performance due to pressure drops.

necessary in Well
Water Installations
In well water applications it may be necessary to deploy the ClearHome cartridge tank with a contaminant reduction
cartridge after a qualifying backwashing filter. This is to protect the lifespan and capacity of the contaminant reduction
cartridge.
NOTE: It is necessary that all treated water from the ClearHome cartridge tank flows through the meter
of the associated unit. This is to ensure proper recording of gallons used through the meter.
SERVICE ALARM
The service alarm on the qualifying softener or backwashing filter must set to 75,327 gallons. This indicates the life of
the cartridge. Once 75,327 gallons has been reached, the controller will display a “Call Dealer For Service” message on
the display of the controller along with an audible alarm on some models. After triggering, the audible alarm may be
turned off by pushing any button on the front of the controller. This will only disable the audible portion of the alarm.
The display will continue to display “service is required”.
Call servicing dealer for cartridge replacement and to reset the service alarm.

LABELING
A certified contaminant reduction system is
comprised of a ClearHome cartridge tank, a
contaminant reduction cartridge (CT-05-CB-
AMCYL-IO), and a qualifying softener or filter with
a PID.
This certification is recognized by a certification
label placed on the tank just below the CT nut,
as shown on the right. This Label Part Number
100393370 may only be used with a certified
system that meets all of the requirements above.
The labeling consists of the model number of the
system, a certification statement, the replacement
cartridge model number, and information that is specific to the system.
The system is deemed certified once all of the preceding requirements have been met. On initial setup, upon verifying
all requirements have been met, the included label must be placed on the tank in the position shown above. It is not
required to re-label the system when performing service.
