Roller Pumps
Pump Speed Control Knob
Use the pump speed control knob to set the pump speed. Turning the
knob clockwise increases the speed, counterclockwise decreases the
speed. Always use the Start/Stop button to stop the pump.
Note: The roller pump does not deactivate at 0 RPM or a flow of 0.000
L/min. This is different than the centrifugal pump behavior which does
stop and deactivate at 0 RPM.
