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.
