The Aprilaire Humidifier is a whole-house indoor air quality product designed to add moisture to the air in your home, operating on the evaporative principle to maintain optimum relative humidity (RH) during the heating season. This system is manufactured by Aprilaire, a recognized leader in the heating and air conditioning industry, and is available in various models including 350, 360, 400A, 500A, 500M, 600A, 600M, 700A, and 700M.
The core function of the Aprilaire Humidifier is to introduce moisture into the dry, hot air circulated by your furnace. Except for Models 350 and 360, the humidifier operates in conjunction with the furnace blower motor. When the humidifier control calls for humidity and the blower motor is running, water flows to a distribution tray at the top of the humidifier. This water is uniformly distributed across a scientifically designed system of outlets and flows by gravity over the Water Panel® evaporator. Dry, hot air from the furnace is then moved through this moisture-laden Water Panel, where natural evaporation takes place. The now-humidified air, carrying moisture in vapor form, is then circulated throughout your home.
Models 350 and 360 utilize service hot water (maximum 140°F) as a heat source to aid evaporation. While the water entering the humidifier is hot, the flushing water to the drain will be cold, as heat is extracted during the evaporation process. The correct water flow is regulated by an orifice, ensuring a small, steady stream of water to the drain. This flushing action helps remove most trouble-causing minerals, preventing their accumulation and eliminating problems associated with stagnant water. The Model 400A is designed for homes where drain facilities are not accessible or where water hardness is not an issue, as it does not require a drain.
The humidifier's operation is controlled by either an Automatic Digital Humidifier Control or a Manual Humidifier Control. The Automatic Digital Humidifier Control senses indoor RH and outdoor temperature, automatically adjusting the humidifier's operation time to provide the optimum humidity level. It displays the RH level in the cold air return duct and features indicator lights for "Call Dealer for Service" (red), "Change Water Panel" (yellow), and "Humidifier On" (green). The Manual Humidifier Control requires manual adjustment based on outdoor temperature to prevent excessive condensation.
