About This Product
Installation Video Included.

The GeneralAire Drum Humidifier is based on the evaporative pad method of adding moisture to the air.  A polyurethane pad forms the surface of a slowly rotating drum which is hydrated as it turns in an automatically controlled level of water and is installed on a vertical plenum surface of any forced air furnace.  It is recommended that the humidifier be mounted on the return air plenum.  This humidifier can be installed with the outlet to the right, or to the left by reversing the motor mounting plate and bypass collar. 

Standard Features:

  • Unique design allows for right or left-hand installation
  • Removable front cover and water reservoir slides out
  • Split drum permits easy separation from removable polyurethane foam sleeve
  • Fits vertical plenum of any forced air heating system
  • Includes 6" diameter bypass assembly, 1/4" tubing and saddle valve
  • M3 Select-Control Manual Humidistat included
  • High capacity, 18 gallons per day

Product Specifications
Maximum Coverage Area
Maximum coverage area means this humidifier will perform well for home sizes up to the square footage indicated, provided that the home is “tight”. A tight home is typically is one that is sealed well around windows and doors and does not leak air to/from the outdoors. Note that humidifiers will perform well for smaller homes as well since the controller regulates the amount of humidity automatically to adjust to home size.

Water Capacity
 
14 Gallons/Day 

Electrical Requirements
Humidifiers with 24 volt AC electrical requirements obtain such by connecting to either 24VAC from the furnace, or by adding a transformer to the furnace to create such. Most installations can use the 24VAC that is already accessible in the furnace.

Humidifiers with 110 volt AC electrical requirements simply plug into a standard outlet (receptacle) and require no special wiring for this part. It is recommended, however, that the outlet/receptacle be dedicated for the humidifier, and that it can be shut off by the same power safety switch that turns off the furnace.  
24V  

Remote Sensing Bulb
A remote sensing bulb is a small (about ¼” round) sensor that mounts outside the home and connects by light gauge wire (18 to 22 gauge, 2-conductor) to the humidifier controller. This sensor provides temperature readings to the computerized controller which allows the humidifier to automatically adjust humidity levels in the home based on outside air temperature.
