24 Jan We have an H2O flow alarm on our Delatech 859 scrubber. How do I troubleshoot the problem?
If your flow is actually low and you can see that by the front flow meter, then you have to determine if it is in the lower section, or the Delatech itself.
First, disconnect the line from the pump that is going up into the cabinet, and run a temporary line to the tank. Hold the line in the tank and start the pump. What is the flow? If it is back to normal, then you know your pump and bottom filter are OK.
If it is still low, it is either your Y filter or your pump. If it is normal then you need to check your nozzle,s because they are likely clogged.
