Maintenance NOTE: Always disconnect the power supply from the control box before any maintenance or cleaning operation is carried out. Clean Sensors In the event of a diaphragm failure the sensor housing will need to be cleaned to remove all traces of product that may stop the system from resetting and thus the pump from re-starting. - Page 11 Main Control Unit The main control unit requires no maintenance, should a fault be suspected please notify Flotronic Pumps Ltd who can advise the best course of action. It may be necessary to return the item to Flotronic Pumps Ltd for investigation.
- Page 12 Pump Shut Down Check Once it is confirmed that the sensors are functioning correctly the pump should be reassembled to perform the ‘pump shut down check’. To perform this check: Connect the power supply to the main control unit. Turn on the air supply to the pump. The pump should not start and the red LED indicator on the main control unit should be flashing.
