6. Operating Instructions
6.1 Temperature Control
The main lever on the pressure balance valve controls the water temperature. Rotate the lever to adjust between hot and cold water. The pressure balancing feature will maintain a consistent temperature, preventing scalding.
6.2 Diverter Function
The upper knob on the valve acts as a 2-way diverter. Rotate this knob to select the desired water outlet:
- Rotate to one side for the rain shower head.
- Rotate to the other side for the handheld shower.
- Position the knob in the middle to activate both the rain shower head and the handheld shower simultaneously.
6.3 Handheld Spray Settings
The handheld shower head features 5 adjustable spray settings. Rotate the spray face of the handheld unit to cycle through the different patterns: rain shower, rain shower with massage, massage, fast massage, and full body spray.
7. Maintenance and Care
7.1 Cleaning the Shower Heads
The rain shower head and handheld shower head are equipped with silicone nozzles. To clean mineral deposits or clogs, simply squeeze the silicone nozzles to dislodge any buildup. This self-cleaning function helps maintain optimal water flow.

7.2 Finish Care
The brushed nickel finish is designed to be anti-fingerprint and corrosion-resistant. To maintain its appearance, clean the surfaces with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.

8. Troubleshooting
- Low Water Pressure: Check if the main water supply is fully open. Ensure shower head nozzles are clear of mineral buildup (refer to Section 7.1). Verify that any water restrictors are properly installed or removed as desired.
- Leaks: Ensure all connections are properly tightened and sealed with pipe sealant tape. If leaks persist from the valve, the cartridge may need inspection or replacement. The pressure balance valve includes a stopper for easy cartridge access.
- Inconsistent Water Temperature: The pressure balance valve is designed to prevent this. If temperature fluctuations occur, the valve cartridge may require inspection or replacement.
- Finish Discoloration: Avoid using harsh chemicals or abrasive cleaners. Clean regularly with a soft cloth and mild soap.
