DEALER INFORMATION:

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 water treatment unit is not designed to support the weight of the plumbing.

Do not use Vaseline, 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. Teflon® tape must be used on the threads of the 1” NPT inlet and outlet and on the threads for

the drain line connection. Teflon® 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, #100249864 (CV3193-02). 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

• One Water Conditioner to Filter

• Water Pressure – 25-100 psi

• Water Temperature – 40-100°F (0.5-37.7°C)

INSTALLATION

1. The distance between the drain and the water conditioner should be as short as possible (see #8).

2. The media tank should be installed on a firm, level surface (above or below grade).

3. It is NOT recommended to install any water treatment unit with less than 10 feet of piping between its outlet and the inlet of a water heater.

CAUTION: To protect the unit in the event of a hot water heater backup, the manufacturer recommends the use of an expansion tank

on the outlet side of the unit (see diagram).

4. Do not locate unit where it or its connections (including the drain and overflow lines) will ever be subjected to temperatures under 33°F.

5. Do not subject the tank 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 provision 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.

WELL WATER INSTALLATION MUNICIPAL INSTALLATION

INSTALLATION

Provisions should be made to bypass outside hydrants that are not to have filtered water. It is also advisable to install hose bibs on the inlet

and outside of the filter for future testing and service of the equipment. Where heavy sediment from the well is observed, it is advisable

to install a cartridge or bag-style filter immediately upstream from the filter. A nominal micron rating of 50 to 100 is recommended. The

purpose of this is to protect the control valve of any debris from the incoming water supply. If desired, a cartridge filter may be used after

the system as a polishing filter.

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 unit, also replace the ground clamps/wire. If removing a unit, replace the

piping with the same type of piping as the original to assure plumbing integrity and grounding.

STARTUP INSTRUCTIONS

OPERATION

The FC-1000 City Water Filter requires no backwashing and eliminates the need for a control valve and the extra water needed to regenerate.

The unit is equipped with an upper strainer assembly to prevent mineral loss. Please contact A. O. Smith with any ques ons pertaining to the

FC-1000 installa on.

OPERATING LIMITS

The unit is designed to func on with minimum water pressures of 20 psi, maximum water pressures of 100 psi, and a maximum water

temperature of 100 degrees F.

WATER QUALITY CONDITIONS

For the carbon and scale control media to be eﬀ ec ve, incoming water must be clear, sediment free, with iron less than 0.3 ppm, pH less than

8.3, and hardness below 15gpg.

IN AND OUT VALVE

1. CAUTION: Ensure the In and Out Valve is  ght on top of the tank. DO NOT over ghten.

2. Locate the bypass valve assembly that is packaged with the system. The bypass valve has two red handles that allow you to bypass

the unit, two threaded connec ons for the tail piece kit and two O-ring seal connec ons with nuts for the In and Out Valve. Align the

insert connec on ends with O-rings and nuts to the inlet and outlet connec ons of the control valve. Hand  ghten the nuts.

3. Locate and assemble the tail piece kit. Align tail piece assembly to the bypass valve threaded inlet and insert un l the nut can be

 ghtened. Hand  ghten the nuts.

SERVICE LINE PIPING

1. Keep unit far enough away from walls and other obstruc ons to allow

for servicing the unit. Pipe water ﬁ lter into the service lines. Plumb

the inlet plumbing into the UPFLOW INLET port of the in-out valve.

Plumb the outlet plumbing into the DOWNFLOW INLET port of the

in-out valve. Plumbing the unit for UPFLOW conﬁ gura on will prevent

channeling of the media bed. Always follow local plumbing codes

when installing our water treatment equipment.

2. If sweat ﬁ  ngs are used, be sure soldering is done in such a manner

as not to allow heat to reach the control valve or bypass. If using

copper pipe, make all sweat connec ons away from the tank, strainer,

and head assemblies or the heat will damage them and void warranty.

Use unions on the inlet and outlet connec ons.

3. Pipe a boiler drain into the inlet and outlet piping as shown in the

Drawing to the right.

FILLING FILTER WITH WATER

1. Direct water from the outlet boiler drain to a ﬂ oor drain and ﬂ ush the

plumbing to ensure no glue, tape or shavings enter the unit. With the

bypass closed, open the outlet boiler drain and run water through the

newly installed plumbing to drain.

2. Fully open the outlet bypass and SLIGHTLY crack open the inlet

bypass. Air will slowly be pushed out of the tank and out the drain.

Once water is running out the drain, you can close the inlet bypass

and allow the media to soak for 30 minutes with the bypass and

boiler drain closed. Once soaked, open the boiler drain, and both the

outlet and inlet bypass handles to direct water from the system to

drain. Run water un l the water becomes clear and free of air pockets.

When clear, close outlet boiler drain.

3. The unit is now in the service posi on.

4. If you choose not to pipe in boiler drains, then you should rinse the

system by running water at an outside spigot or nearby sink un l the water is clear and has no ﬁ nes or color. You should thoroughly rinse

the system of its ﬁ nes and color before placing the unit into service posi on.

CARBON/MEDIA LOADING

1. Remove the In and Out valve assembly from the top of the tank and make sure the riser tube is secured to the vortech plate. The distributor is

permanently a ached to the vortech plate so centering is not necessary. The top of the distributor will be 5/8” above the top of the tank.

2. Cover the top opening of the distributor pipe before ﬁ lling the tank with media.

3. Pour the coconut carbon provided with the unit into the top of the tank. Then pour the scale control media on top of the carbon.

4. Remove the material used to cover the top of the distributor pipe and clean the tank threads of any media. Rea ach the in and out valve

assembly.
