Setup and Installation
Pre-Installation Checks
- Ensure the mounting surface is clean, flat, and free of debris.
- Confirm that the sink hole diameter is appropriate for single-hole installation (typically 34-37mm).
- Verify that hot and cold water supply lines are accessible and can be shut off.
Installation Steps
- Prepare the Faucet: Insert the flexible connection hoses into the base of the faucet. Ensure they are hand-tightened.
- Mount the Faucet: Place the faucet through the hole in the sink or countertop. Ensure the base gasket is correctly positioned between the faucet and the sink surface.
- Secure the Faucet: From underneath the sink, slide the rubber washer, metal washer, and mounting nut onto the threaded shaft. Hand-tighten the nut, then use a basin wrench to fully secure the faucet, ensuring it is aligned correctly.
- Connect Water Lines: Connect the hot water supply line to the hot inlet hose (usually marked with red or on the left) and the cold water supply line to the cold inlet hose (usually marked with blue or on the right). Use appropriate wrenches to tighten connections, but do not overtighten.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. If leaks occur, tighten the connections slightly until they stop.
- Flush the System: Remove the aerator from the spout. Turn on both hot and cold water for a few minutes to flush out any debris from the lines. Turn off the water, reattach the aerator.

Operating Instructions
The GROHE BauFlow Single-Lever Sink Mixer is designed for intuitive operation:
- Water Flow Control: Lift the lever handle upwards to increase water flow. Push it downwards to decrease or stop the flow.
- Temperature Control: Move the lever handle to the left for hot water and to the right for cold water. The further left or right you move it, the hotter or colder the water will be.
- Spout Rotation: The high spout can be rotated to direct water flow as needed within the sink area.

Maintenance and Care
To maintain the finish and performance of your GROHE BauFlow faucet:
- Cleaning: Clean the faucet with a soft cloth and mild soap. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the chrome finish.
- Aerator Maintenance: Periodically unscrew the aerator from the spout and clean any mineral deposits or debris that may have accumulated. This helps maintain optimal water flow.
- Cartridge Care: The GROHE LongLife ceramic cartridge is designed for durability. If you notice a change in water flow or temperature control, it may indicate a need for professional inspection or cartridge replacement.
