Product Description AprilAire introduced the first evaporative humidifier for forced air furnace systems back in 1954. Since that time, AprilAire continues to lead the industry in whole home humidification systems – including steam humidifiers. AprilAire steam humidifiers use electrode technology and are simple to install, operate, and maintain. With electrode technology, electrical current flows between submerged electrodes, resistance of the water to the electric current heats the water. The submerged electrodes are found in a replaceable canister. At the end of a humidifier season, the canister – including the electrodes, is replaced. No cleaning, no scrubbing, simply replace the canister and you’re ready for the next humidifier season. Electrode technology requires impurities in the water to promote the transfer of electricity. For this reason, water filtration is not required with electrode technology, minimizing the complexity of the installation and on-going operating costs. This unit will operate with water hardness between 3 and 36 grains – a very wide range. If reverse osmosis or deionized water is present, plumb the steam humidifier to a water line before the water flows through the reverse osmosis or deionization equipment. INCLUDED IN THE BOX: Installation instructions, steam humidifier, Model 62 automatic digital humidifier control with sensor, outdoor temperature sensor, dispersion tube, steam hose (6 feet), 7/8 inch drain tubing (10 feet), hose clamps, saddle valve, mounting screws, Model # 80 steam canister From the Manufacturer The Aprilaire Model 800 Residential Steam Humidifier features truly automatic control, so there's no need to manually control the humidifier - though it can be installed in manual mode, if desired.
