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.
