Operation

Priming the Pump

Before priming the pump or starting the pump, be sure that all suction and discharge lines are connected properly and that proper valves are open.  

Pressing the Prime Key will start the pump at 100% speed and will run for 60 seconds.  The pump can be stopped at any time by pressing the Start/Stop key.  All 60 seconds may not be required to prime the pump.  Conversely, if additional priming is necessary, the Prime key can be pressed again.  

If the pump does not prime, check the suction line for clogs, obstructions, or leaks. Make sure all appropriate valves are open. 

Manual and Remote Operation

To run the pump in Manual Mode, press the Start/Stop key to start the pump running. The LED light above the Start/Stop button will change from Red to Green.  

Adjust pump speed by pressing the Up and Down arrow keys on the touchpad. To stop the pump, press the Start/Stop key.  

If using the pump in Remote/Signal Start/Stop Mode, press the Start/Stop key to put the pump in the “Ready – Standby” state. The display will read “SBY” if waiting for a signal from the user-provided control system. Once a signal is received, the pump will start, and the LED light will turn green. Adjust pump speed manually by pressing the Up and Down arrow keys on the touchpad.  Note the color of the LED light above the Signal Start/Stop key. Green = normally open, Red = normally closed. 

Calibration

To ensure the most accurate pumping, a pump calibration is recommended prior to operating the pump.  The A1A pump flow rate will vary depending on the suction line conditions. Calibrate the pump with actual suction line conditions.     

To calibrate the pump: 

1. Connection tubing and open valves on the suction side of the pump to represent actual suction line conditions 
2. Set up discharge and open discharge valves to dispense into calibration column/cylinder. 
3. Prime to the pump so that the calibration column begins to fill. Stop the pump and note the solution level in the calibration column.  
4. Run the pump at a set speed for 1 minute.   
5. Record the flow difference in the calibration cylinder.  
6. Calculate the flow rate by dividing the flow by the time. For example, if the pump runs for 1 minute, and the flow difference is 30 ml, then divide 30 ml by 1 minute. The flow rate is 30 ml/min.   
7. For best accuracy, run more than one calibration to check results or run another calibration at a different pump speed.

Calibration results should be similar to the flow rating for the pump tube but can vary depending on chemical composition, suction lift, viscosity, temperature, and other conditions.   

Tube Failure Detection (TFD)

The A1A pump is equipped with leak detection located inside the pump head.  If a tube fails or leaks for any reason, the chemical will trigger the sensor, stop the pump, and activate an alarm.  

If TFD alarm occurs, the pump will stop, close an alarm output, and the screen will flash. If the system has detected a chemical, the pump tube must be replaced, and the pump head and roller must be thoroughly cleaned. 

Remove the front cover to replace the tube and roller. Failure to clean the pump head properly will void the warranty. See the video on proper tube replacement.  https://www.blue-white.com/bw-videos/the-blue-white-academy-how-to-replace-the-a1-m1-tubing/
