2. Configurazione e installazione
Proper installation is crucial for the optimal performance of your Waterdrop AP431 filter. Ensure you have all necessary tools and fittings before beginning. The system should be installed on your main water line before your water heater or pressure tank, allowing sufficient space for maintenance.

- Chiavi regolabili
- File (per sbavare i tubi)
- Teflon tape (for threaded fittings)
- Matita o pennarello
- 1" Quick Connect Adapters (if applicable)
- Drill (for mounting bracket)
- Screws (for mounting bracket)
2.2 Passaggi di pre-installazione
- Chiudere l'erogazione idrica: Individua e chiudi l'alimentazione idrica principale della tua casa.

- Prepare Fittings: Wrap the pipe threads of your quick connect adapters with approximately 6 inches of Teflon tape in a clockwise direction.
- Attach Fittings to Filter Head: Screw the prepared fittings into the filter head by hand, then use a wrench to tighten them firmly. Avoid over-tightening.
2.3 Mounting and Pipe Connection
- Seleziona Località: Choose an appropriate installation location on your main water line, ensuring it's before the water heater and allows sufficient clearance (at least 1.5 inches below for housing removal).
- Misura e segna: Measure the length of the filter head with adapters attached. Mark this length on your pipe, accounting for additional room for pipe engagement into the adapters.
- Tubo tagliato: Use a pipe cutter or hacksaw to remove the marked section of pipe. File down any sharp edges or burrs.
- Montare la testa del filtro: If using a mounting bracket, align it with the filter head and secure it. Then, drill the bracket into a sturdy surface (e.g., wood stud) to support the system's weight.
- Collegare i tubi: Push the cut pipe ends firmly into the quick connect adapters on the filter head until they hit a hard stop. Ensure the water flow arrows on the filter head match your home's water flow direction.
