Skuttle water panel used in the under-the-duct model 55UD. Includes the water distribution wick. Measured size: 11 x 12½ x 1½", but the sizes may vary an 1/8". Replace once a year. Hard water conditions may require changing twice a year. We have noticed with hard water that calcium deposits can build up and fall off, then end up in the duct. A high quality water filter suitable for use in food service equipment is recommended. The water panel is made of layers of an aluminum mesh with a porous pumice-like coating. The coating allows the water panel to absorb water. When time to discard the aluminum can be recycled. When used the coating will be loose and can be rinsed off.
Aprilaire Flow-Thru humidifiers have a solenoid with a small strainer filter in the body. These strainers should be inspected and cleaned when replacing the water panel. If the strainer becomes clogged the water pressure will tear it and pieces will jam the solenoid or loose pieces will block the orifice.
