Cleaning the Condensate Drain System

The condensate drain system traps dust and dirt. Clean the drain system once a year.

  1. Shut off the rocker switch and unplug the unit.
  2. Remove the duct on the evaporator inlet.
  3. Inspect the drain pan under the coil.
  4. If drain pan appears soiled, pour some hot water mixed with liquid bleach (diluted solution) along the length of the pan to flush the dirt down the drain tube.
  5. Continue this treatment until the drain appears clean and free of dirt.
  6. Reinstall the duct collar.
  7. Plug in the unit and restart.
