_]BRINING: During brining, the brine is moved from the salt storage area, into the resin tank. Inside

the resin tank, brine cleans hardness minerals from

the resin beads and they are discharged out the

drain. How much brine is needed to clean the resin

depends on:

--the amount of resin in the softener,

--how fast the brine goes through the bed.

The nozzle and venturi (FIG. 6) make suction to take brine from the salt tank and put it into the resin tank. They keep the brine flow down to a ve W slow rote to

get the best resin cleaning with the least salt.

[] BRINE RINSE: After all of the brine goes into the

resin tank, the brine valve closes. Water keeps

flowing the same way it did during brining except

the brine flow has stopped. Hardness minerals and brine flush from the resin tank to the drain. Brining

and brine rinse together vaw in the length of time they take, relative to the fill cycle length.

[5]FAST RINSE: Backwash is followed by a fast flow of water down through the resin tank. The fast flow packs the resin bed and gets it ready for return to service (FIG. 8).

After fast rinse, the softener returns to service. Hard water goes into the resin tank where the resin bed again takes out the hardness minerals. Soft water goes to the house soft water pipes.

the drain. The bed lifts and expands for good cleaning.

625.34857, 625.34859 specifications

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.
