RevAir has 2 different illuminated light sequences within the Handle to help diagnose the issue

Light  Sequence Guide

• Fast flashing sequence = 1 sec in between each flash.  This is an indicator the device is not getting proper airflow which can be caused by the below:
  • Clogged/Dirty filter - water should be able to freely run through the mesh portion of the filter.  If water is standing still or slowly draining your filter needs a good scrub.  Click HERE for directions on how to clean
  • Kink in hose - check the entire length of the hose to see if there are any kinks or damaged areas
  • Back of the unit is too close to a wall not allowing exhaust air to freely move

• Slow Flashing Sequence = 3 seconds in between each flash.  This is an indicator the Filter or Filter Panel are not connected.  Check the following:
  • Unlock the Filter panel 
  • Remove the Filter & Reinsert ​(should hear 2 soft clicks)​
  • Then reinsert the Filter Panel and Relock​​
  • Power back on and turn tension dial on to 2
