Installation in Submersible Pump Sump
This controller is not for use with
3-phase pumps or Variable Frequency
pump installations.
1. Shut off the power to the STP.
Remove power to avoid possible
electrocution or ignition of explosive
gasoline vapors.
2. Remove the plug from the STP electrical junction
box cover and save the plug.
If the STP junction box does not have a removable plug or
opening, installation adapters are available as listed below.
