Setup and Installation
The Kingston Brass KB3005AL Volume Control is designed for standard plumbing installations. Professional installation is recommended.
- Prepare the Installation Area: Ensure the main water supply is turned off. Clear the area where the volume control will be installed.
- Install the Valve Body: The valve body features 1/2-14 NPT connections. Connect the inlet and outlet plumbing lines to the valve body. Use appropriate thread sealant (e.g., PTFE tape or pipe dope) on all threaded connections to ensure a watertight seal. Ensure the valve body is securely mounted within the wall according to local plumbing codes and the rough-in dimensions.
- Install the Faceplate: Once the valve body is installed and tested for leaks (after turning water back on briefly), position the faceplate over the valve body. Secure it using the provided screws.
- Attach the Handle: Place the lever handle onto the valve stem. Secure it with the set screw, typically located on the underside of the handle. Ensure the handle operates smoothly through its full range of motion.
- Final Check: Turn the main water supply back on and check for any leaks around the valve body and trim. Operate the handle to ensure proper water flow control.

Operating Instructions

Maintenance
To maintain the appearance and functionality of your Oil Rubbed Bronze volume control, follow these guidelines:
- Cleaning: Clean the surface regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or polishes, as these can damage the finish.
- Oil Rubbed Bronze Finish: This finish is designed to age gracefully, developing a unique patina over time. Regular cleaning with mild soap and water is sufficient.
- Periodic Checks: Periodically check for any signs of leaks or loose connections. Tighten as necessary, but do not overtighten.
