- Verify that your existing plumbing is compatible with a standard US NPT 1/2" thread.
- If your valve is buried too deep, an extension kit is available upon request to ensure proper fit and function.
Installation Steps
For detailed, step-by-step installation instructions, please refer to the official Installation Manual (PDF) available at: Installation Manual (PDF).
Key considerations during installation:
- Properly secure the rough-in valve within the wall according to local plumbing codes.
- Connect the hot and cold water lines to the designated inlets on the valve.
- Install the shower arm, rain shower head, handheld shower holder, and handheld showerhead.
- Utilize the included test plug to check for leaks before sealing the wall.

Operating Instructions
Water Flow and Temperature Control
- The single handle controls both water flow and temperature. Rotate the handle to adjust temperature (typically counter-clockwise for hotter, clockwise for colder).
- Pull the handle outwards to increase water flow and push inwards to decrease or shut off.
- The pressure-balanced valve automatically adjusts water pressure to maintain a consistent temperature, preventing sudden changes due to household water usage fluctuations.
Shower Head Selection
- The diverter knob on the control valve allows you to switch between the rain shower head, handheld spray, or use both simultaneously.
- To use the rain shower head, turn the diverter to the designated position.
- To use the handheld spray, turn the diverter to its designated position.
- For simultaneous operation of both shower heads, turn the diverter to the combined setting.

Maintenance
Cleaning
- To maintain the polished chrome finish, clean regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome fixtures.
- Avoid using abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- For shower head nozzles, gently rub the rubber nozzles to dislodge any mineral buildup.
Internal System Care
- The system features anti-backflow check valves and a buffer device within the valve core to prevent water hammer noise and protect your pipes. These components are designed for long-term, low-maintenance operation.
- Regular water flushing through the system helps prevent sediment buildup.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent water temperature (sudden hot/cold changes) | Fluctuations in household water pressure. | The pressure-balanced valve is designed to mitigate this. Ensure proper installation and check main water supply pressure if issues persist. |
| Low water flow from shower heads | Mineral buildup in nozzles; low household water pressure. | Gently rub rubber nozzles to clear mineral deposits. Check main water supply pressure. |
| Water hammer noise | Rapid changes in water flow causing pipes to vibrate. | This system is designed with anti-backflow check valves and a buffer device to prevent water hammer. If noise occurs, consult a plumber to check overall plumbing system. |
| Valve buried too deep in wall | Installation depth issue. | An extension kit is available upon request to accommodate deeper valve installations. Contact KES customer support. |
| Components do not fit bathroom setup | Specific plumbing or design requirements. | KES offers parts customization to meet specific bathroom needs. Contact customer support for assistance. |
