Kenmore water softeners remove hardness minerals and some clear water iron from the water supply in a home. Before installing the water softener, perform water system tests to determine the settings you will run the water system at. Determine where to install the water softener and decide what type of pipes you want to run—typical soldered copper in and out pipes, PVC or threaded in and out pipes.
Assemble the Inlet-Outlet adapters or plastic bypass valve. Close the house shut-off valve; shut-off the water heater gas or electric supply. Open the highest and lowest faucets in the home to drain. Install the holding clips. They snap into place on the inlet and outlets.
Install the bypass valve. It clips onto the valve inlet and outlet on the top of the water softener under the cover. Optionally, install a 3-valve bypass. Cut the house main water pipe where you will connect the softener.
Locate and connect the water softener. Move the softener into position on a level surface and connect the softener with plastic bypass valve to the inlet and outlet pipes. Or, connect the water softener directly to the input and output pipes if you are using a 3-valve bypass.
Connect the valve and salt tank drain hoses. Run the tank overflow drain hose from the grommet on the side of the tank to a floor drain. Run the valve drain hose from the drain fitting on top of the softener to the floor drain.
Perform a pressure test and check for leaks.
Connect the grounded electrical supply. Install the covers on the water softener and re-start the home's water heater.
