4. Oppsett og installasjon
Proper installation is crucial for the pump's performance and safety. If you are unsure about any step, consult a qualified professional.
4.1 Montering av pumpen
- Choose a stable, level surface for mounting. The pump should be installed below the water source if possible to aid in priming.
- Secure the pump using the integrated mounting feet. Ensure there is enough space around the pump for ventilation and maintenance.

Figur 4.1: The pump features sturdy mounting feet for secure installation.
4.2 VVS-tilkoblinger
- 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.

Figur 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.

5. Bruksanvisning
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.

Figur 5.1: The pump features an automatic pressure switch for demand-based operation.
6. Vedlikehold
Regelmessig vedlikehold sikrer optimal ytelse og forlenger pumpens levetid.
- Inspiser tilkoblinger: Periodically check all plumbing and electrical connections for leaks or damage. Tighten as necessary.
- Clean Strainer: Regularly inspect and clean the inlet strainer to remove any accumulated debris. A clogged strainer can reduce pump performance and lead to damage.
- Vinterisering: 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.
- Generell rengjøring: Keep the exterior of the pump clean and free from dirt and dust.
