ON/OFF button. The warning stays active, the pump should not be run with no foam concentrate owing.
If the foam pump motor RPM sensor information is lost the system operates using a pre-programmed plot based
on the current draw of the motor.
If the ow sensor information is lost the system is operated in the manual mode. Refer to Manual Mode.
To complete ushing the system press the ON/OFF button. (If the FLUSH button is pressed, the system re-starts
