Installation Instructions
- Prepare the Installation Area: Ensure the rough-in valve (e.g., K-11748-K-NA or K-11748-KS-NA) is correctly installed according to its specific instructions and local plumbing codes. The valve body should be securely mounted and plumb.
- Install the Trim Plate: Apply a bead of silicone sealant around the back of the trim plate to create a watertight seal against the finished wall. Position the trim plate over the valve body and secure it with the provided screws.
- Install the Handle Assembly: Attach the handle adapter to the valve stem. Align the lever handle with the adapter and secure it with the set screw, typically located on the underside of the handle.
- Install the Showerhead and Tub Spout: Thread the shower arm into the wall fitting and then attach the showerhead. For the tub spout, apply thread sealant to the pipe threads and screw the spout onto the pipe, ensuring it is properly aligned and tightened.
- Test for Leaks: Turn on the main water supply and check all connections for leaks. Operate the faucet handle to ensure proper water flow and temperature control.
Note: Specific installation steps may vary slightly depending on the rough-in valve model and your specific plumbing configuration. Always refer to the detailed instructions provided with your KOHLER Rite-Temp valve.
Operating Your Faucet Trim
- Turning On/Off: Rotate the lever handle to turn the water on or off.
- Temperature Control: Rotate the lever handle to adjust the water temperature. Typically, rotating counter-clockwise increases hot water, and clockwise increases cold water.
- Diverter Function: The Rite-Temp valve system includes a push-button diverter. Pull the button to divert water flow from the tub spout to the showerhead. Push the button back in to return water flow to the tub spout.
Care and Maintenance
To maintain the finish and performance of your KOHLER faucet trim, follow these guidelines:
- Cleaning: Clean the faucet trim with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Spot Removal: For stubborn spots, use a mild soap and water solution, then rinse thoroughly and dry with a soft cloth.
- Avoid Wax-Based Cleaners: Do not use cleaners containing wax, as they can build up and dull the finish.
- Showerhead Cleaning: Periodically clean the showerhead nozzles to remove mineral deposits. Many KOHLER showerheads feature flexible nozzles that can be rubbed to dislodge deposits.
