3. Safety Information
Always turn off the main water supply before attempting any installation or maintenance. It is recommended to consult a qualified plumber for installation to ensure compliance with local plumbing codes and safety standards. Wear appropriate personal protective equipment, such as safety glasses and gloves, during installation. Do not use harsh chemicals or abrasive cleaners on the product finish.
4. Setup and Installation
The KES XB6250-BK shower system is designed for wall-mount installation. The rough-in valve features a cUPC certified pressure balance ceramic disc cartridge, which helps prevent scalding from sudden changes in water pressure. If inlet water temperature varies seasonally, follow the included instructions to adjust the temperature limit stop. The recommended water temperature for showering is between 90°F - 110°F (32°C - 43°C).
4.1 Rough-in Valve Installation
Install the rough-in valve according to standard plumbing practices, ensuring it is securely mounted within the wall. Connect the hot and cold water lines to the appropriate inlets on the valve. The valve body is constructed from sturdy brass for durability.

4.2 Trim Kit and Components Installation
Once the rough-in valve is installed and tested, proceed with installing the faceplate, handle, shower arm, rain shower head, slide bar, and handheld shower components. Ensure all connections are tight and leak-free. The 12-inch rain shower head is made of SUS304 stainless steel.
