Setup and Installation
The Cerafine O mixer is designed for wall-mount, single-hole installation. The built-in body is integral to the installation process.

- Water Connections: Connect the hot and cold water supply lines to the designated inlets on the built-in body. Ensure secure, watertight connections.
- Outlet Connections: Connect the outlet for the shower and the 1/2" outlet for the bathtub. The diverter mechanism will control flow between these two.

Operating Instructions
Your Cerafine O mixer features a single lever for controlling both water flow and temperature, along with an integrated diverter for selecting between bath and shower functions.
- Turning On/Off: Lift the single lever to turn on the water flow. Push it down to turn off.
- Adjusting Flow: The further you lift the lever, the greater the water flow.
- Adjusting Temperature: Move the lever left for hotter water and right for colder water. The 47mm EKO system cartridge is designed for efficient temperature control.
- Using the Diverter: The integrated diverter allows you to switch water flow between the bathtub spout and the shower outlet. Typically, this is a pull-up or push-down mechanism on the mixer body.
Maintenance
Regular cleaning and proper care will help maintain the appearance and functionality of your mixer.
- Cleaning: Clean the mixer regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or chemical solvents, as these can damage the finish.
- Rinse Thoroughly: After cleaning, rinse the surface thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Cartridge Maintenance: If water flow or temperature control becomes inconsistent, the cartridge may need cleaning or replacement. This should be performed by a qualified professional.
Troubleshooting
If you encounter issues with your mixer, refer to the following common problems and solutions:
- Low Water Flow: Check if the main water supply is fully open. Mineral deposits can accumulate in the aerator or cartridge; cleaning or replacing these components may be necessary.
- Leaks from Handle/Spout: Leaks often indicate a worn-out cartridge or seals. The cartridge may need to be replaced by a professional.
- Inconsistent Temperature: This can be due to issues with the water heater, imbalanced water pressure, or a faulty cartridge. Consult a professional plumber.
- Diverter Not Switching: Mineral buildup or a faulty diverter mechanism can prevent proper switching. Cleaning or replacement may be required.
For persistent issues, contact a qualified plumber or Ideal Standard customer support.
