Mounting Honeywell humidifier on furnace.?

Where is the best place to mount a humidifier, on supply or return duct? Or does it not matter?

depends on type of humidifier..if its the type that uses a bypass duct for its airflow then it doesnt matter.....if its the type that has its own fan built in then it needs to go on the supply duct......also refer to instruction manual for the water connection...i assume its the type that has fresh water flowing through it while its on,no sump with recirculated room temp water...if you have a heat pump then you need to connect to hot water...if gas furnace ,hot water prefereable but cold will work...if oil heat , cold water should be ok...also be sure to wire it so it only runs when the furnace blower is on,,and be sure to mount the humidistat per the install instructions........dan
