5. Instruccions de funcionament
The WASSERMANN Water Pressure Diaphragm Pump is designed for automatic operation based on water demand:
- Inici automàtic: When a water fixture (e.g., faucet, shower, hose nozzle) connected to the pump's outlet is opened, the pressure in the system drops, and the pump's internal pressure switch will automatically activate the pump.
- Parada automàtica: When all water fixtures connected to the pump's outlet are closed, the pressure in the system builds up to the preset 45 PSI, and the pump's pressure switch will automatically turn the pump off.
- Autoamorçant: The pump is self-priming, meaning it can draw water from a source without needing to be manually filled with water first. Ensure the inlet hose is submerged in water for optimal priming.

6. Manteniment
Un manteniment regular garanteix la longevitat i el rendiment òptim de la bomba:
- Neteja de filtres: Periodically inspect and clean the debris filter located on the pump's inlet side. A clogged filter can reduce flow and pressure. To clean, unscrew the clear housing, remove the mesh filter, rinse it thoroughly, and reassemble.
- Inspecció de connexió: Regularly check all hose connections and fittings for leaks or signs of wear. Tighten or replace as necessary.
- Hivernització: If the pump will be exposed to freezing temperatures, it is crucial to drain all water from the pump and connected lines to prevent ice damage.
- Neteja general: Keep the exterior of the pump clean and free from dirt and debris.
