Configurazione e installazione
The Waterdrop under sink water filtration system is designed for drill-free installation, utilizing a twist-and-lock setup for convenience. It connects directly to your existing cold water line.
- Preparare l'area di installazione: Clear the under-sink cabinet area. Ensure the main water supply to the sink is turned off.
- Installare il rubinetto: If a dedicated faucet is included and required, install it in a pre-drilled hole on your sink or countertop. Secure it firmly.
- Connect to the Filter Unit: Attach the water tubing to the inlet and outlet ports of the filter unit. The twist-and-lock mechanism ensures a secure connection. The suction cup base helps stabilize the unit.
- Collegamento alla rete idrica:
- Individuare il tubo di alimentazione dell'acqua fredda sotto il lavandino.
- Disconnect the existing faucet's cold water line from the angle stop valve.
- Install the provided 3/8" line or use the 3/8" to 1/2" converter if necessary, to connect the filter system to the cold water supply valve.
- Reconnect your existing faucet's cold water line to the new connection point.
- Connect to the Faucet: Connect the filtered water outlet tubing from the filter unit to the dedicated faucet.
- Controllare eventuali perdite: Slowly turn on the main water supply. Check all connections for any signs of leaks. Allow water to run through the new faucet for several minutes to flush the system and remove any air.
