4. Configuració i instal·lació
Seguiu aquests passos per a una instal·lació correcta:
- Col·locació: Position the pump on a stable, level surface in a well-ventilated area, protected from direct sunlight and freezing temperatures.
- Connexió d'entrada: Install the provided check valve at the inlet. Ensure at least two interface gaskets are placed. It is recommended to wrap adapters with raw tape (Teflon tape) before installation to prevent water leakage. The pump has a 1-inch inlet.
- Connexió de presa: The pump comes with a pre-installed adapter at the outlet. Connect your water system or garden hose to the 1-inch outlet.
- Connexió elèctrica: Plug the pump into a standard 110V AC outlet. The 20 ft power cord provides ampel arribar.
- Priming (if necessary): For initial use or after extended periods of non-use, ensure the pump is properly primed by filling the pump casing with water before starting.

5. Instruccions de funcionament
The pump is designed for automatic operation based on water demand.
- ON/OFF automàtic: The intelligent pressure switch automatically turns the pump on when water is drawn (e.g., opening a faucet) and turns it off when water flow stops.
- Ajust de pressió: The cut-in pressure can be adjusted using the pressure screw behind the pressure tank. This allows you to set the desired starting pressure for the pump.
- Monitorització de la pressió: The built-in pressure gauge provides a visual indication of the current water pressure in the system.
