HUMIDIFICATION
Installation and Maintenance of
Armstrong EHU-600 Series Humidifiers
The Armstrong EHU-600 Series humidifier is an electronically controlled,
non-pressurized, electric steam-generating humidifier, with its vapor discharged into a
duct of an air-handling system or through a fan package.
To allow the EHU-600 Series humidifier to function to its full capability, be certain to
install in accordance with Armstrong recommendations.
These installation and maintenance guidelines should be used by experienced person-
nel as a guide to ensure that the Armstrong EHU Humidifier functions correctly. Selection
or installation of equipment should always be accompanied by competent technical
assistance. We encourage you to contact your local representative or Armstrong if further
information is required.
