Determining Best Location for Humidifier
• Select a location for the humidifier on the supply (warm
air stream) duct. See Fig. 1 for examples. Return duct
mounting is acceptable if there are space restrictions
on the supply duct. If you are mounting the humidifier
on the return duct, simply swap “return duct” for
“supply duct” throughout these instructions.
• Select a location that cannot damage the air
conditioner A-coil during installation.
• Do not locate the humidifier on the furnace body.
• Mount the humidifier in a conditioned space to prevent
freezing.
• Mount the humidifier at least 3 in. (78 mm) above the
furnace body to allow adequate space for the solenoid
valve and drain line.
