If the pump has lost prime you need to find out why e low water level in the ECARS these tanks are not protected with a level sensor that will turn the pump off in the event of a low water situation Check the tank water level and the drain line valve Also check for any leaks in the system e a leak in the inflow pipe can cause air to be sucked into the pump resulting in the pump cavitating this is an unlikely situation as the pumps are below water level and should remain flooded at all times a blockage of the inflow line 2 The intake pipe is blocked Check the blue inflow screen in the tank and clean if necessary 3 One of the valves in the system is closed Check all valves in the system open as necessary Once the problem is solved you may need to manually start the pump from the Argus control system This will cool the sensor enough for normal operation to resume Once water flow is restored this alarm and any others e g Temperature Deviation Flow Problems should reset If all of these options fail to restore flow you will need to contact the Aqualab Manager 519 831 1671 Flow Problems or No Flow Alarm There are 12 ECARS located within Room 151 This alarm monitors the recirculation paddlewheel flow sensor The recirculation system is composed of a magnetic drive pump Page 17 of 22 a bubble washed bead filter a temperature controller and an ultraviolet sterilizer The pump is controlled by Argus Argus monitors
