Plug the 3.5-foot power cord into a standard 115V AC wall socket. Ensure the outlet is properly grounded.
4. ఆపరేటింగ్ సూచనలు
The WASSERMANN water pressure pump features an automatic pressure switch for convenient operation.
- పవర్ ఆన్: Once installed and connected, plug in the pump.
- ఆటోమేటిక్ ఆపరేషన్: The pump will automatically activate when a tap or water outlet is opened, supplying water. It will stop when the tap is closed, maintaining stable water pressure and conserving energy.

4.1 Adjusting Pressure (If Necessary)
The factory default pressure setting is 55 PSI. If adjustment is required:
- Locate the red rubber sleeve in the center of the pressure switch and open it.
- Use a pressure regulator needle (or small screwdriver) to adjust the pressure. Turning clockwise increases pressure, and turning counter-clockwise decreases pressure.
