Pressure tank's pressure & Pump max head & Pressure range of switch & Using height:
| Rated Power (W) | Max. pump head (m) | Cut Off (bar) | Cut In (bar) | Water tank pressure (bar) | Max. tap height (m) |
| H | P1 | P2 | P3 | L | |
| H | P1 | P2=P1-0.8 | P3≈P2 | L | |
| 150 | 19 | 1.8 | 1.0 | 1.0 | <10 |
| 250 | 25 | 2.4 | 1.6 | 1.6 | <16 |
1. Reg the precharge pressure of the pressure tank (P3), it's must smaller than the cut-off of pressure switch (P1);
and we suggest that the precharge pressure of the tank (P3) be close to the cut-in of switch(P2).
So the water can into the pressure tank and act as a buffer;
2.The cut-in of switch(P2) decide the max using height (L);
3.The cut-off of the switch (P1) must be smaller than the max pump head of the pump/10 (H/10) ;
And we suggest to smaller around 0.5bar than the H/10,to avoid the real head drops caused by seal parts damaged after the pump is used for a period of time.
It's not recommended to adjust the pressure setting by self.
