Operating Instructions
The KOHLER Anthem Two-Port Thermostatic Valve provides precise control over your shower experience. Operation is typically managed through the compatible control panel trim.
Basic Operation:
- Temperature Control: Use the main temperature control on your trim panel to set the desired water temperature. The thermostatic valve will maintain this temperature consistently, even with fluctuations in water pressure.
- Outlet Selection: The two independently controllable ports allow you to direct water to different shower outlets (e.g., a main showerhead and a hand shower). Use the corresponding controls on your trim panel to activate and deactivate each outlet.
- Flow Adjustment: Some trim panels may offer individual flow control for each outlet. Adjust as needed for your preferred water intensity.
- High-Temperature Limit: The valve features an adjustable high-temperature limit stop to prevent accidental scalding. This is typically set during installation but can be adjusted if necessary (refer to trim kit instructions).
- Comfort Setting: The adjustable comfort setting is preset at approximately 104°F (40°C) for a comfortable showering temperature.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your thermostatic valve.
Recommended Maintenance:
- Cleaning: Clean the visible parts of the valve trim regularly with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Check for Leaks: Periodically inspect the area around the valve for any signs of water leaks. Address any leaks promptly to prevent water damage.
- Water Quality: In areas with hard water, mineral deposits can accumulate over time. If you notice a decrease in performance or temperature fluctuations, consult a qualified plumber to inspect and potentially clean the internal components of the valve.
- Professional Inspection: Consider having a qualified plumber inspect your plumbing system, including the thermostatic valve, periodically to ensure everything is functioning correctly.
