About This Product
The Aprilaire Model 600M takes humidifier innovation to the next level and performs as good as it looks! The Aprilaire 600M is easier than ever to install because it includes a built-in bypass damper, which means fewer parts to install. Plus, the damper is conveniently labeled for summer and winter settings, allowing you to set it for the entire season with no guesswork involved. This humidifier can be installed on the supply or return air ductwork. It is also left or right side reversible. Includes manual control humidistat, water pad, 110v to 24v transformer.
Other items needed for the installation that are not included: 1/4″ copper tubing for water line, 1/2″ ID plastic tubing for drain, 6″ round ducting & elbow for bypass air, 2-conductor 18 to 22 gauge wire.
Product Specifications
Type
There are two basic humidifier types: bypass and power fan. Each simply uses a different method to move air through them. Power fan humidifiers use a 110 volt fan to move air through them. Bypass humidifiers do not have a fan, but instead require a 6” duct to be connected to the side and then to the opposite air duct system from the humidifier. That means for bypass models that if the humidifier is installed on the supply plenum, the 6” duct will connect to the humidifier and the return plenum, and if the humidifier is installed on the return plenum, the 6” duct will attach to humidifier and the supply plenum.
Bypass
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.

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.
