I’m Jay, and this is the Aprilaire 4182 distribution tray. It is located on the inside of the humidifier, and installed on top of the pad frame. The purpose of the tray is to act as a reservoir for water, before it is distributed onto the water panel. The cover for the tray is available separately. Within the tray are eight holes, along with a fabric liner used to evenly disperse water. This material is necessary for your humidifier to function properly. Earlier versions of this tray were equipped with a granular coating, rather than the fabric liner. The tray should be replaced every five to eight years – sooner if the fabric liner or granular coating is damaged or missing. This item is also available as part of the maintenance kit for your model.

Replacement is easy. Here’s how.
Be sure to turn the power off before performing any maintenance.
Before performing this service, it is necessary to shut off the water. Find the saddle valve, turn it clockwise until it stops.

Alright, let’s slide the water panel into the scale control insert. You’ll notice there are slots cut into it; they line up with the little tabs here. It snaps into place. Now we’re going to put the top on it, which also snaps into place. And the assembly is now ready to be installed inside of your humidifier.
