Adjusting the switch-on pressure of your VONROC GP527AC Automatic Pump is straightforward. First, ensure the pump's ON/OFF switch is set to 'O' before connecting it to a power supply. Then, switch the pump to 'I' to turn it on. The pressure switch manages the pump's operation automatically. Open a connected tap or spray gun to start the pump; some initial air in the water is normal and will dissipate. When you close the tap or spray gun, the pump will automatically stop. To adjust the switch-on pressure, find the pressure setting mechanism on the pump. Each full rotation of this mechanism changes the switch-on pressure by approximately 0.2 bar. Turn clockwise to increase the pressure and counter-clockwise to decrease it. Set the switch-on pressure between 1.5 bar and 2.5 bar, based on your specific needs. This process allows you to tailor the VONROC GP527AC's performance to your requirements.
