4. Configuració i instal·lació
Follow these steps for quick and proper installation of your diaphragm pump:
- Muntatge: Securely mount the pump in a dry, well-ventilated area using the stable bracket. Ensure it is on a flat, stable surface to minimize vibration.
- Connexió d'entrada: Connect the water inlet hose to the designated inlet port (often labeled 'Inlet' or indicated by an arrow pointing towards the pump). It is recommended to install the included filter on the inlet line to prevent debris from entering the pump.
- Connexió de presa: Connect the water outlet hose to the designated outlet port (often labeled 'Outlet' or indicated by an arrow pointing away from the pump).
- Connexió elèctrica: Connect the pump's power wires to a 12V DC power source. Ensure correct polarity (red wire to positive, black wire to negative). It is advisable to install an inline fuse for protection.
- Encebar la bomba (si cal): While this is a self-priming pump, ensuring the inlet line is filled with water before the first use can aid in faster priming.
- Comproveu si hi ha fuites: After all connections are made, slowly introduce water into the system and check for any leaks at the fittings. Tighten connections as needed.

5. Funcionament
Once installed, operating the DXQ FL-40 pump is straightforward:
- Inici de la bomba: Ensure all connections are secure and the power source is ready. Apply 12V DC power to the pump. The pump will begin to operate and self-prime.
- Funcionament automàtic: The pump is designed to automatically turn on when water is demanded (e.g., a faucet is opened) and turn off when the demand stops and pressure builds up in the system.
- Flow and Pressure: The pump delivers a maximum flow of 17 L/min and maintains pressure up to 40 PSI.
- Seguiment: Comproveu periòdicament la bomba per si hi ha sorolls, vibracions o fuites inusuals durant el funcionament.
6. Manteniment
Un manteniment regular garanteix la longevitat i el rendiment òptim de la bomba:
- Neteja de filtres: Regularly inspect and clean the inlet filter to prevent clogging and maintain optimal flow. Disconnect power, remove the filter housing, clean the mesh screen, and reassemble.
