Key Installation Considerations:

• Cartridge Modification for 3 Devices: If you intend to use three showering devices, the transfer valve cartridge must be modified. This simple modification changes the valve's flow from two outlets to three. Consult the official manual for precise instructions on this modification.
• Capping for 2 Devices: When using only two showering devices, the designated outlet 3 must be capped. Caps are sold separately and are essential to prevent leaks and ensure proper function.
• Integrated Mounting Bracket: Utilize the integrated mounting bracket to secure the valve directly to a brace, which simplifies and speeds up the rough-in process.

Operating Instructions

The Moen U361CI M-CORE Transfer Valve allows you to direct water flow to various showering devices. The specific operation will depend on whether your system is configured for two or three devices.

• Functionality with 2 Showering Devices: When configured for two devices, the valve provides two independent outlets and one shared outlet. This means you can select device 1, device 2, or both device 1 and device 2 simultaneously.
• Functionality with 3 Showering Devices: When configured for three devices (requiring cartridge modification), the valve offers three independent outlets and three shared functions. This allows for selection of device 1, device 2, device 3, or combinations such as 1+2, 1+3, 2+3, or 1+2+3.

Refer to your specific trim kit's instructions for details on how to rotate the handle to select the desired showering device(s).

Maintenance

To ensure the long-term performance and appearance of your Moen M-CORE Transfer Valve, follow these general maintenance guidelines:

• Regular Cleaning: Clean the visible parts of the valve trim regularly with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
• Inspect for Leaks: Periodically check for any signs of leaks around the valve body or connections. Address any leaks promptly to prevent water damage.
• Cartridge Longevity: The ceramic disc valve type is designed for durability. If you experience issues with water flow or temperature control, the cartridge may need inspection or replacement. Consult a professional plumber for cartridge-related issues.
• Winterization (if applicable): In areas prone to freezing temperatures, ensure proper winterization procedures are followed for your plumbing system to prevent damage to the valve from frozen pipes.
