Armstrong World Industries EHU-703 - Manual (Page 5)

The mounting surface should be a wall capable of supporting the maximum humidifier weight.
The maximum operating weight is:
The location chosen should be inside with a minimum ambient temperature of 40°F. and a maximum of
100°F. The humidifier should not be mounted on hot surfaces.
The location should be close enough to the air duct so that the length of steam pipe is as short as
possible. A length of 10 ft. or less is ideal; the maximum recommended length for running distribution
piping is 40 feet of equivalent run. The number of piping elbows in the installation should be minimized
(see Pages 7 and 8 for more information.)
The unit should have ready access to electrical service, a supply of ordinary tap water, and a sewer
into which the drain line can discharge hot waste water. (Figure 5-1)
NOTE:
Please contact factory for duct applications offering high static pressure (>4" WC).
