4. INSTALLATION AND SIZING CONSIDERATIONS
The Well-X1
™
functions like a traditional pressure switch by cycling the pump on and off. The factory pressure settings
are 40 psi cut-in and 60 psi cut-out. The controller allows these settings to be adjusted to best suit the application. The
Well-X1
™
can operate in two primary modes:

A. STANDARD OPERATION
Using a standard 20 psi differential, the Well-X1
™
can be sized according to the chart below. In this
application, the sizing and performance will be similar to a traditional pressure tank and mechanical
switch combination.
B. CONSTANT PRESSURE MODE
The Well-X1
™
control allows a narrow differential to provide consistent water pressure. The factory 20
psi differential can be reduced so the cut-in and cut-out pressures are within 10 psi. When installed as
a constant pressure system, the chart below should be used to ensure the tank volume is sufficient to
provide adequate cycle protection.
The maximum working pressure of the Well-X1
™
is 125 psig. Do not
exceed the maximum working pressure.
