4. Setup and Installation
The BLANCO FONTAS-S II faucet is designed for single-hole installation. A 35 mm faucet bore is required for mounting. Ensure you have all necessary tools and components before beginning.
Installation Steps:
- Prepare the Sink/Countertop: Ensure a clean, dry surface with a 35 mm diameter hole for the faucet.
- Mount the Faucet: Insert the faucet into the prepared hole. Secure it from underneath the sink using the provided mounting hardware, including the stabilization plate to enhance stability.
- Connect Water Hoses: Attach the flexible 350 mm connection hoses (3/8 inch nut) to the hot and cold water supply lines. Ensure a tight, leak-free connection.
- Connect Filtered Water Line: Connect the dedicated filtered water line to your external water filter system (filter not included with faucet).
- Check for Leaks: Slowly turn on the main water supply and inspect all connections for any signs of leakage.
- Test Functionality: Operate both the tap water and filtered water levers to ensure proper flow and temperature control.
The ceramic cartridge ensures smooth operation and durability. The patented jet aerator is designed to reduce limescale buildup.
5. Operating Instructions
Tap Water (Hot & Cold):
The right-hand lever controls the standard hot and cold tap water. Move the lever forward or backward to adjust water flow. Move it left for hot water and right for cold water.
Filtered Water:
The left-hand rotary handle controls the filtered water. Rotate this handle to activate the flow of filtered water. This water is delivered through a separate internal conduit and spout, ensuring it remains unmixed with tap water.
Pull-Out Spout:
Gently pull the end of the main spout to extend the pull-out spray. This feature allows for greater flexibility in rinsing and cleaning tasks. After use, guide the spout back into its housing.
Swivel Function:
The faucet spout can swivel 360 degrees, providing maximum flexibility for various sink configurations and tasks.
6. Maintenance
Cleaning the Faucet:
To maintain the black silgranit finish, clean the faucet regularly with a soft cloth and mild soap. Rinse thoroughly with clean water and dry immediately to prevent water spots. Avoid using abrasive sponges, scouring agents, or chemical cleaners containing alcohol, ammonia, or bleach, as these can damage the surface.
Aerator Maintenance:
Periodically unscrew and clean the aerator at the tip of the spout to remove any mineral deposits or debris that may affect water flow. The patented jet aerator is designed to reduce limescale, but occasional cleaning is still recommended, especially in hard water areas.
Filter Replacement:
The BLANCO FONTAS-S II requires an external water filter system (not included). Refer to the instructions provided with your specific water filter for recommended replacement schedules and procedures. Regular filter replacement is crucial for maintaining water quality.
7. Troubleshooting
- Low Water Flow: Check if the aerator is clogged with debris or limescale. Clean or replace as necessary. Ensure water supply valves are fully open. For filtered water, check the external filter for clogs or if it needs replacement.
- Leaks from Spout: Ensure all connections are tight. If leaking from the spout itself, the internal cartridge may need inspection or replacement by a professional.
- Dripping Faucet: This often indicates a worn-out ceramic cartridge. Contact customer support for replacement parts or professional assistance.
- Water Temperature Issues: Verify that both hot and cold water supply lines are correctly connected and fully open.
For persistent issues, please contact BLANCO customer support.
