Disable Extended Run Feature in the Pump Controller
Certain pump controllers may be programmed to turn off the pump after an extended run
period and post an ER (Extended Run) error in the controller. Because the Vac Sensors may
require the pumps to run for several hours and possibly triggering this error, disable this ER
feature in the pump controller. Refer to the Pump Controller’s documentation for instruc-
tions on how to disable the Extended Run feature.
