4.1 Required Tools (Not Included)
- Adjustable wrench
- Screwdriver (Phillips and/or flathead)
- Plumber's tape
- Sealant (if required by valve instructions)
4.2 Installation Steps (General Overview)
- Ensure the Rite-Temp valve body is correctly installed and secured within the wall according to its specific instructions.
- Attach the escutcheon plate to the valve body, ensuring it is level and flush against the wall. Secure with provided screws.
- Install the handle assembly onto the valve stem. Ensure proper alignment for temperature and flow control.
- Test for leaks by slowly turning on the main water supply and inspecting all connections.
- Adjust temperature limit stop if necessary, following the Rite-Temp valve instructions.
5. Operation
The KOHLER Parallel Rite-Temp Valve Trim features a single handle for controlling both water flow and temperature.
- On/Off Activation: Rotate the handle to turn the water on or off.
- Temperature Setting: Rotate the handle to adjust the water temperature. The Rite-Temp valve's pressure-balancing diaphragm technology maintains the outlet temperature within +/-3°F (approximately +/-1.7°C) during water pressure fluctuations, providing anti-scald protection.
6. Care and Cleaning
To maintain the finish of your KOHLER Parallel Rite-Temp Valve Trim, follow these guidelines:
- Clean regularly with a soft, damp cloth.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- For stubborn spots, use a mild soap solution and rinse thoroughly with water, then dry with a soft cloth.
- KOHLER finishes are designed to resist corrosion and tarnishing, ensuring long-lasting beauty with proper care.
7. Troubleshooting
If you experience issues with your valve trim, refer to the following common solutions:
- Low Water Flow: Check for debris in the valve or connected showerhead/faucet aerator. Ensure water supply lines are fully open.
- Inconsistent Water Temperature: Verify that the Rite-Temp valve is correctly installed and calibrated. If the issue persists, professional inspection may be required to check the pressure-balancing unit.
- Leaking: Ensure all connections are tight. If leaking continues from the trim, the internal components of the Rite-Temp valve body may require professional service or replacement.
- Handle Stiffness: Over time, mineral deposits can affect handle movement. Clean the area around the handle base. If stiffness persists, the valve cartridge may need inspection.
