Operation
This humidifier operates using the evaporative principle in a quiet, efficient and automatic
manner. It is constructed of the highest quality, engineering grade materials to assure superior
performance and durability. This humidifier is controlled so that it operates only when the
furnace blower is operating and the humidistat, which is installed on the cold air return duct or
in your living area, calls for humidity.
When there is a call for humidity and the circulating air blower is operating, the solenoid valve
opens and water flows into the distribution tray and trickles down through the evaporator pad.
Warm, dry air is drawn through the evaporator pad, where it absorbs moisture and is returned
to the duct, and is circulated throughout the house. There is no standing water in this humidifier,
thus reducing maintenance and handling. The drain, located at the bottom of the unit, allows
unused water to drain from the humidifier and flush away mineral deposits that have been left
behind after the evaporation process. A fluid restrictor located in the evaporator pad supply
tubing controls the amount of water flowing through the humidifier.
Do NOT attempt to control the flow of water by using the saddle valve. It is designed to be
either fully open or closed.
A felt pad located in the distribution tray distributes water evenly between the openings. The
distribution tray should be inspected annually and any plugged holes cleaned (more frequently
in areas of poor water quality).

Air Tightness of Home
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 on-time of 70%
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 .5 changes per hour.
An “Average Home” is insulated and has a dampered fire place, 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.
