Selecting a Location
1. For most installations, mount the humidifier under the horizontal warm air
supply duct. As an alternative, the unit can be mounted on a vertical
plenum using a fabricated transition for support. (See “Mounting the
Humidifier”, pgs. 8-10.)
NOTE
: Ideally, the Skuttle Steam Humidifier is not intended for installa-
tion in or on the return air duct or plenum. However, some contractors do
so without complications. If you choose to install a Skuttle Model 60
Humidifier under a return air duct or on a return air plenum, be aware
that moisture MUST be absorbed BEFORE entering the filter, blower,
turn or transition. Therefore, INSTALL THE HUMIDIFIER AT LEAST
4-TO-6 FEET PRIOR TO THESE DEVICES AND CONFIGURATIONS.
2. Select a location where the humidifier can be plugged in without the use
of an extension cord. (See separate manual, “Wiring Instructions for High-
Capacity Steam Humidifiers”.)
3. Select a location that will not allow steam to condense on the system air
mover, electrical components, etc.
4. Mount the unit on rigid metal ductwork, never on duct board or internally-
insulated duct.
