The above calculations are for reference only and are based on the following:
•Inside temperature 70° F/35% relative humidity
•Outside Temp 20° F /70% relative humidity
•8 foot ceiling height
•Internal moisture gain of one pound per hour
•Furnace
This chart uses A.R.I. standard designations:
A “Tight Home” is assumed to be well insulated with vapor barriers, tight storm windows and doors, and a dampered fireplace. Air exchange rate of .50 changes per hour.
An “Average Home” is insulated and has a dampered fireplace, but there are no vapor barriers, storm doors, or storm windows. Air exchange rate of 1.0 change per hour.
A “Loose Home” is generally one constructed before 1930, has little or no insulation, no storm doors, storm windows, weather stripping or vapor barriers, and often no effective dampering of fireplaces. Air exchange rate is as high as 1.5 changes per hour.
Operation
Your centrifugal atomizer type humidifier operates on the principle of breaking down water droplets into a fine mist and atomizing the moisture into the air.
If applicable, set the humidistat in the recommended range of
When shutting the humidifier down for the summer months, start with cleaning any mineral accumulation from the unit. Leave the water turned off and the unit dry. If the furnace fan is to be used for cooling purposes, disconnect power to the humidifier or turn the humidistat to the OFF position.
