5B.ROTARY VALVE SERVICE

Before working on the valve, turn off the water

supply and disconnect from electrical power.

TO RELIEVE PRESSURE:

--3VALVE BYPASS: Close the inlet valve and (:)pen a soft water faucet. Then close the outlet valve and

(:)pen the bypass valve.

--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 water with 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 disassemble.

SERVICING THE VALVE

Inspect all (:)-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 tOuse the

current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper position. Lubricate ALL ()-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 ()-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

tightening 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.

The Kenmore 625.34859 and 625.34857 are notable water filtration systems designed for residential use, offering an efficient way to ensure clean and safe drinking water. These units are characterized by their advanced filtration technologies and user-friendly features that cater to the needs of modern households.

One of the main features of these models is their multi-stage filtration process, which effectively removes contaminants such as chlorine, sediment, and various impurities found in tap water. The filtration system includes a sediment filter, a carbon filter, and a reverse osmosis membrane, working synergistically to improve water quality significantly.

The reverse osmosis technology is a standout aspect of the Kenmore 625 series. This method utilizes a semi-permeable membrane that allows only water molecules to pass through while blocking larger molecules and contaminants. As a result, users enjoy cleaner, better-tasting water free of harmful substances. The filtration process is further complemented by a post-carbon filter that enhances the taste and removes any remaining odors.

Another significant characteristic is the high capacity of these systems. With a storage tank that provides ample water supply, families can conveniently access filtered water whenever needed without the frequent need for cartridge replacements. The POU (Point of Use) design allows for easy integration into kitchen setups, making it an ideal solution for cooking, drinking, and food preparation.

Furthermore, the Kenmore 625.34859 and 625.34857 come equipped with monitoring technology that alerts users when filter changes are needed. This feature eliminates the guesswork, ensuring that the systems operate at peak efficiency and maintain optimal water quality.

Installation of these units is user-friendly, often requiring only basic plumbing skills, making it accessible for DIY enthusiasts. Additionally, both models are designed for low maintenance, offering long service life and reliability, which makes them an excellent investment for those looking to elevate their home water quality.

In summary, the Kenmore 625.34859 and 625.34857 are advanced water filtration systems that combine effective multi-stage filtration, cutting-edge reverse osmosis technology, high capacity, and user-friendly features. Their ability to deliver purified water consistently makes them a popular choice for families looking to improve their drinking water quality and ensure their health and well-being.
