This document is an installation guide for Kohler single-control bath and shower faucet trim, covering models K-T461, K-T462, K-T463, K-T464, K-T465, and K-T466. It provides comprehensive instructions for installation, usage, and maintenance, with a strong emphasis on safety and proper temperature adjustment.
Function Description
The Kohler single-control bath and shower faucet trim is designed to regulate water flow and temperature for both bath spouts and showerheads. It features a pressure-balancing valve that helps maintain a consistent water temperature, preventing sudden changes due to fluctuations in hot or cold water supply. The trim includes various components such as a valve, faceplate, sleeve, handle, spout, and showerhead, all working together to provide a controlled and comfortable bathing experience. The pressure-balancing valve is crucial for safety, especially in preventing scalding, and its proper adjustment is a key part of the installation process.
Important Technical Specifications
- Models Covered: K-T461, K-T462, K-T463, K-T464, K-T465, K-T466.
- Safety Standard Compliance: The valve meets or exceeds ANSI A112.18.1 and ASSE 1016 standards, which are critical for ensuring product safety and performance, particularly concerning temperature regulation and scald prevention.
- Maximum Water Temperature: The water temperature should never be set above 120°F (49°C) to prevent personal injury from scalding. This is a critical safety specification that installers must adhere to during the temperature adjustment process.
- Spout Nipple Requirement: For spout installation, a 1/2" nipple is required, extending 7/16" (1.1 cm) beyond the finished wall. This precise measurement ensures proper fit and sealing of the spout.
- Thin Wall Installation Kit (88526): For installations involving K-306-KS HiFlow valves in fiberglass or acrylic units, a thin wall installation kit (88526) is necessary. This kit ensures proper mounting and stability in specific wall types.
- Sealant Requirements: Thread sealant tape is recommended for threaded connections (e.g., spout nipple, shower arm) to prevent leaks. Plumbers putty or other sealants are used for the back of the spout and shower flange to create a watertight seal against the finished wall. Silicone sealant is also mentioned for tiled wall installations around the back edges of the faceplate.
- Tools Required: Assorted screwdrivers, thermometer, plumbers putty, thread sealant, hex wrench, strap wrench, and silicone sealant. These tools are essential for a successful installation and proper adjustment.
Usage Features
- Single-Control Operation: The faucet trim features a single handle that controls both water flow and temperature, offering ease of use and precise adjustment.
- Pressure-Balancing Valve: This core feature automatically adjusts the mix of hot and cold water to maintain a constant temperature, even when other water-using devices in the household are turned on or off. This prevents sudden and potentially dangerous temperature spikes or drops.
- Temperature Adjustment: The valve allows for both minor and major temperature adjustments. Minor adjustments can be made by adjusting a setscrew, while major changes require removing the O-ring and collar from the valve stem and rotating the stem to achieve the desired maximum temperature. This flexibility allows users to customize their preferred maximum water temperature within safe limits.
- Handle Alignment: The handle assembly is designed to be aligned in a specific position (e.g., lever handle pointing straight down) and pressed onto the valve stem, ensuring correct orientation and operation.
- Sleeve and Faceplate Installation: The design includes a sleeve and faceplate that cover the valve body, providing a finished aesthetic and protecting the internal components. The sleeve can be rotated to align with the handle assembly setscrew, and the faceplate is secured with screws.
- Showerhead and Spout Functionality: The trim supports both a bath spout and a showerhead, allowing users to switch between the two functions as needed. The installation guide provides separate instructions for installing each component, ensuring proper sealing and functionality.
Maintenance Features
- Temperature Re-checking: After any temperature adjustment, it is crucial to re-check the water temperature with a thermometer to ensure it meets the desired maximum temperature and remains within safe limits (below 120°F/49°C).
- Excess Putty Removal: During installation, any excess plumbers putty or sealant should be removed to maintain a clean appearance and prevent buildup.
- Regular Cleaning: Although not explicitly detailed in the provided excerpts, the nature of faucet trims generally implies regular cleaning of the visible components (faceplate, handle, spout, showerhead) to maintain hygiene and aesthetic appeal.
- Valve Label Information: If a valve label is supplied, it is important to complete the required information after temperature adjustment. This likely serves as a record of the set maximum temperature, which can be useful for future maintenance or safety checks.
- Product Design Revisions: Kohler Co. reserves the right to make design modifications without notice, as specified in the Price Book. This implies that users should refer to the latest documentation for their specific model if significant changes occur.
- Customer Support: The document emphasizes contacting Kohler's Customer Service Department (1-800-4-KOHLER) for any installation or performance issues, highlighting the availability of support for troubleshooting and maintenance. This is a key maintenance feature, as it provides a direct channel for users to get assistance with their product.
