How can I adjust the switch-on pressure of my VONROC GP527AC Automatic Pump?

[LeFaith]

Adjusting the switch-on pressure of your VONROC GP527AC Automatic Pump is straightforward. Here's a step-by-step guide:

1. Ensure the pump's ON/OFF switch is set to 'O' (off) before connecting the pressure switch to the power supply.
2. Move the ON/OFF switch to the 'I' position to turn the pump on.
3. The pressure switch manages the pump's operation automatically. Open a connected tap or spray gun to start the pump. It's normal to have some air in the water initially; this should clear within a few minutes.
4. When you close the tap or spray gun, the pump will automatically stop.
5. To adjust the switch-on pressure, find the pressure setting mechanism on the pump. Each 360-degree turn of the mechanism changes the switch-on pressure by approximately 0.2 bar.
6. To increase the pressure, turn the mechanism clockwise. To decrease the pressure, turn it anti-clockwise.
7. Set the switch-on pressure between 1.5 bar and 2.5 bar, based on your specific requirements. This range ensures optimal performance for most applications. By following these instructions, you can easily customize the VONROC GP527AC Automatic Pump to your needs.
