4. Configurazione e installazione
This sink is designed for undermount installation. Professional installation is recommended to ensure proper fit and function. Ensure you have all necessary tools and materials before beginning.
Passaggi di pre-installazione:
- Inspect the sink for any damage before installation. Do not install a damaged sink.
- Ensure the countertop opening is correctly sized for an undermount sink. Refer to the sink dimensions and manufacturer's template (if provided) for precise cutout requirements.
- Gather all required plumbing components, including drain assembly, faucet, and supply lines.
Installation Procedure (General Guidelines):
- Apply a continuous bead of silicone sealant or plumber's putty around the rim of the sink where it will contact the underside of the countertop.
- Carefully position the sink under the countertop opening, ensuring proper alignment.
- Secure the sink to the countertop using the provided mounting clips and hardware. Tighten evenly to create a secure seal, but do not overtighten.
- Install the drain assembly and faucet according to their respective manufacturer's instructions.
- Connect the water supply lines to the faucet and the drain to the P-trap.
- Turn on the water supply and check for any leaks at all connections.

5. Funzionamento
The PROFLO PF1812U sink operates like any standard bathroom sink. Water flows from the faucet into the basin and drains through the main drain opening. The integrated overflow system helps prevent the basin from overflowing if the main drain becomes blocked or the faucet is left running.
- To use, turn on the faucet to the desired water temperature and flow.
- Ensure the drain stopper (if installed) is open for water to drain.
- In case of a blocked drain, the overflow holes will redirect excess water into the drain system, preventing spillage onto the countertop or floor.
6. Manutenzione
Regular cleaning and proper care will help maintain the appearance and longevity of your PROFLO sink.
Istruzioni per la pulizia:
- For daily cleaning, use a soft cloth or sponge with mild soap and warm water.
- Rinse the sink thoroughly after cleaning to remove all soap residue.
- Wipe the surface dry with a soft cloth to prevent water spots and mineral buildup.
- Avoid using abrasive cleaners, scouring pads, steel wool, or harsh chemicals (e.g., strong acids, alkalis, drain cleaners) as these can damage the vitreous china finish.
- Periodically clean the overflow holes to ensure they remain clear and functional.
