Pressure switch setting
How to adjust the pressure setting
The pressure switch of the domestic waterworks has a factory setting that must be adjusted to the pump capacity and your requirements when installing the pump on site.
+ Increase pressure - turn clockwise
- Reduce pressure - turn counter-clockwise
1. Differential pressure should remain unchanged
Adjust the stop pressure on the long screw (A).
- The switch-on pressure changes automatically, so there is no need to adjust the small screw.
2. Differential pressure needs to be adjusted
- Adjust the switch-on pressure using the small screw (B).
- Caution: Proceed with care, as even the slightest movements can cause significant changes in pressure.
3. Switch-on and switch-off pressure should be adjusted
- Completely loosen the differential screw (B) to adjust.
- Adjust switch-on pressure on long screw (A)
- Then screw in the short screw (B) until the desired stop pressure is reached.
