Overview
The Aprilaire Model 800 Steam Humidifier is a self-contained device that takes tap water and boils it, using electrode technology, to create steam. The
humidifier generates steam by energizing two electrodes that extend into a canister of water. Current flowing between the electrodes causes the water to boil, creating steam. The steam flows through a steam hose and is injected into a moving airstream by the way of a distribution tube. The steam flows out of the
distribution tube into the ductwork through a series of small tubelets which create an even, drip-free transfer of steam into the moving airstream.
NOTE: The only difference between the 800 and the model 801 is that the 801 has a modulating control board but the 800 has an on-off control board.
Cylinder Maintenance
In normal conditions, the disposable cylinders should be replaced after one year. They must be replaced immediately – even before the specified intervals – if any anomalies occur. For example, when the lime scale inside the cylinder prevents the correct flow of electric current.
