    If the 5500 Steam Humidifier remains powered but idle (i.e. without producing steam) for more than 72 hours (3 days), the cylinder will automatically be emptied of water and will not refill until the unit is restarted. If there is no water in the cylinder, there will be no current flow and no steam production.

  • Page 6: Cylinder Life

    Use only cold water since the supply water is used to temper the hot drain water. Water quality affects the operation of this unit, so the 5500 Steam Humidifier should be supplied with water that is untreated, drinkable, not softened, and not demineralized.
