The location should be close enough to the air duct so
that the length of steam hose or pipe is as short as
feasible. A length of 10 ft. or less is ideal; the maximum
recommended length for running copper tube is 40 feet.
See Page 6, Item 6 of the Installation Section for more
details on steam dispersion tube location.
See Figures 4-1 and 4-2 for access space.
The location chosen should be inside with a minimum ambient
temperature of 40°F. and a maximum of 100°F. The unit should have
access to electrical service, a supply of ordinary tap water, and a drain
line for waste water to sewer. The humidifier should not be mounted on
hot surfaces.

Mounting The Humidifier
The EHU-600 Series is intended to be mounted on a wall by means of
3/8" diameter lag screws or other suitable fasteners capable of
supporting the maximum operating weight of the humidifier.
Model EHU-600: Making sure the humidifier is level, hold it against the
mounting surface to mark the hole pattern. Make sure the screws will
go into studs or other sturdy structure. Fasten the humidifier to the wall
using the four 3/8" x 1 1/2" lag screws provided (See Fig. 4-3).
Models EHU-601 and EHU-602: Fasten the mounting bracket (see Fig.
4-2 and 5-1) to the wall with the two 3/8" x 1 1/2" lag screws provided.
Make sure the screws will go into studs or other sturdy structure. Hang
the humidifier cabinet on the mounting bracket. Install the #8 x 1/2" self
tapping screw from inside the humidifier cabinet so that it goes through
the holes in the cabinet and the mounting bracket. (Model EHU-602
has two screws). This locks the cabinet to the mounting bracket.
