-- SEARS SPECIAL BYPASS: Slide the bypass valve stem to bypass position. Loosen the 3 hex head screws (see A in drawing) toward the back side of the valve to allow pressure water to bleed out (catch waterwith a rag).

DISASSEMBLY

To remove a part or group of parts, refer to the valve drawing. A common screwdriver or nut driver, Phillips screwdriver and pliers are the only tools needed to completely disassembe.

SERVICING THE VALVE

Inspect all o-rings, seals and gaskets for wear or defects.

Inspect the bottom surface of the rotor and disc for scratches, chips or wear.

NOTE: If replacement is needed, be sure to use the current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper position. Lubricate ALL o-rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-section). Apply a light coating of silicone grease to the seal’s crossing ribs. Then, carefully center the wear strip on the seal, and push it downward onto the seal.

Install the nozzle and venturi seal and drain seal. Assemble 2 o-rings and the wave washer onto the rotor and disc. Then center the rotor and disc, in the valve body, on the rotor seal.

Lower the cover onto the valve body and rotor shaft. Then install the cover holding screws. Before tight- ening the screws, install the valve cam and gear. Then, turn the rotor (clockwise only) to service position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds.

screen

Lubricate the gear on the motor, and the valve cam gear with Molykote grease, or other high qualitygear lubricant.

Be sure to orient switch as shown, with lever toward the cam.

625.348321 specifications

The Kenmore 625.348321 is a highly regarded model in the realm of water softeners, designed to alleviate the challenges posed by hard water in households. This unit effectively addresses the mineral buildup caused by calcium and magnesium ions, improving water quality and enhancing the longevity of plumbing fixtures, appliances, and laundry.

One of the standout features of the Kenmore 625.348321 is its impressive grain capacity. With a capacity of 31,000 grains, it is well-suited for medium to large households. This ensures that families experience consistent and reliable soft water, preventing the telltale signs of hard water, such as scale buildup and dry skin.

The process involves exchanging the hard water minerals for sodium ions, effectively capturing the unwanted hardness and leaving users with soft, palatable water. This not only enhances the efficiency of soaps and detergents but also promotes the health of plumbing systems and appliances by preventing mineral deposits.

An additional feature is its demand-initiated regeneration system. This technology allows the unit to monitor water usage and regenerate only when necessary, which results in reduced salt and water consumption. This energy-efficient approach not only helps lower utility bills but also contributes to a more sustainable household environment.

The Kenmore 625.348321 also boasts user-friendly programming options, enabling homeowners to easily set and adjust preferences for optimal performance. The intuitive interface allows for quick access to diagnostics and system performance, ensuring that users are well-informed about the status of their water softening system.

Moreover, this model is equipped with a large brine tank that can hold a significant amount of salt, minimizing the frequency of refills and simplifying maintenance. With its compact design, the water softener fits seamlessly into various spaces, making it a convenient choice for homes with limited installation areas.

In summary, the Kenmore 625.348321 stands out as an effective water softener, combining advanced technology with user-friendly features. It provides households with the benefits of soft water, ensuring cleaner clothes, softer skin, and extended appliance life—all key advantages for any modern home.
