Ofbylding 4.1: The pump features sturdy mounting feet for secure installation.
4.2 Loodgietersferbiningen
- Identify the inlet and outlet ports on the pump. The inlet typically has an arrow indicating water flow direction.
- Install the included filter (strainer) on the inlet side of the pump to prevent debris from entering and damaging the pump. Hand-tighten only.

Ofbylding 4.2: The included strainer filter should be installed on the pump's inlet to protect against debris.
- Connect your water supply line to the inlet and the distribution line to the outlet using the appropriate hose adaptors provided. Ensure all connections are tight to prevent leaks.
- The pump is self-priming, meaning it can draw water from a source without needing to be manually filled with water first.

Ofbylding 4.3: Example plumbing diagram illustrating the pump's integration into a typical water system.
4.3 Elektryske ferbining
- Ensure the pump's power cord is easily accessible.

The WASSERMANN 4WDP5-55-115V pump is designed for automatic operation.
- Once connected to power and water lines, the pump will automatically start when a tap or fixture is opened, causing a drop in water pressure.
- The pump will automatically stop when the tap or fixture is closed and the system pressure reaches the shut-off point (55 PSI).
- The integrated pressure switch and bypass switch work together to maintain consistent water flow and prevent frequent starts/stops, especially with small flow demands.

Ofbylding 5.1: The pump features an automatic pressure switch for demand-based operation.
6. Underhâld
Regelmjittich ûnderhâld soarget foar optimale prestaasjes en ferlingt de libbensdoer fan jo pomp.
- Ynspektearje ferbinings: Periodically check all plumbing and electrical connections for leaks or damage. Tighten as necessary.
- Skjinmeitsje de filter: Regularly inspect and clean the inlet strainer to remove any accumulated debris. A clogged strainer can reduce pump performance and lead to damage.
- Winterisaasje: If the pump is installed in an area subject to freezing temperatures, it must be drained completely or protected with non-toxic antifreeze to prevent damage.
- Algemiene reiniging: Keep the exterior of the pump clean and free from dirt and dust.

Ofbylding 6.1: Internal components of the pump, including the 100% solid copper motor, shaft seal, diaphragm impeller, pump body, and pressure/bypass switch.
