Has anyone seen a humidifier installed this way: humidifier installed to side of air handling unit (hole drilled into side of AHU and discharging humidified air directly into the AHU). Always thought humidifier was to be attached to either intake or output ducts?
A steam type humidifier is installed is this fashion. The steam does not need the extra air flow. The water type will only work marginally without the duct work.
