The pressure in the system is
199P
SubDrive Connect Surface Pump
Possible Cause
- Leak in system
199psi or higher.
Corrective Action
- Correct pressure and
placement as necessary
- Tank may be too small for
system flow
- This is not a drive problem
- Disconnect power and check
pressure gauge for pressure drop
- Set deeper in the well or tank;
install a flow sleeve with airtight
seal around drop pipe and cable
- If fluctuation is only on branches
before sensor, enable Steady Flow
- Change tank size configuration
- Reduce frequency output range
- Reduce System Response
then reduce P and I value
The max pressure the display can
show is 199psi. Use the pressure
gauge or Wi-Fi / FE-Connect app
to view the system pressure.
