Drain Pan Mounting
Drain Pan Mounting
A drain pan is an additional safety feature which may be required to be supplied in the field. In a proper
humidifier installation, a drain pan is not required. However, if the humidifier and injection tube are located in
an area that contains valuable equipment or is a water sensitive area, PURE Humidifier Co. recommends the
addition of a drain pan under the humidifier and under the injection tube. The drain pan should extend past
all edges of the humidifier and if installed in the duct, it should extend a minimum of 3 feet (91 cm)
downstream from the injection tube. The pan should be capable of draining at a rate of 3 gpm. The pan
should be drained to a sanitary drain.
