How To Change The Water Panel on The Aprilaire 500 Whole Home Humidifier

Change the Aprilaire 10 water panel on your Aprilaire 500 whole home humidifier in a few easy steps! Before you begin any maintenance, your first steps are to turn off the water supply, unplug the system, and turn off the electrical source to the furnace.

  1. To replace your water panel, first take off the front cover on your Aprilaire 500 humidifier. This easily snaps out of place.
  2. Remove the water panel frame, then take the water distribution tray off the top of the frame. Take a second to make sure that these holes are clear of any mineral build-ups. If   necessary, run it under water pressure to remove. The distribution tray is replaceable if the build-up cannot be removed.
  3. Slide the water panel out and replace it with a new one, making sure the colored dot is at the TOP.  Then reassemble the frame and reinsert it back into the humidifier.

For best performance, it is advised that you change your Aprilaire 10 water panel once a season, possibly twice if you have hard water. With the Aprilaire 500 your automatic humidistat will notify you with a yellow indicator light when it is time to change your water panel. If you have the 500M, you will have to use other resources to remind yourself when it is time to perform your seasonal maintenance. Remember, you can always consult your owner’s manual to get these step by step instructions in more detail. Or, if you feel most comfortable, you can have your contractor perform this annual maintenance for you.
