Preparation and Installation
Site selection
The humidifier should be installed in an easily accessible location. Do not install the unit where malfunction of the humidifier
might cause damage to non-repairable, irreplaceable or priceless property. Refer to Installation section for other details
regarding site selection.
Do not place electronic steam humidifiers in locations where unusual instances of malfunction of the humidifier or the
system might cause damage to non-repairable or un-replaceable, or priceless property
The mounting surface should be a wall capable of supporting the maximum humidifier weight. Please refer to page 9 for
maximum operating weight. The location chosen should be inside with a minimum ambient temperature of 40°F (+4°C) and
a maximum of 100°F (+38°C). 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 10ft
(3m), or less is ideal; the maximum recommended length for running distribution piping is 40ft (12m) of equivalent run. The
number of piping elbows in the installation should be minimized.
The unit should have ready access to electrical service, a supply of ordinary tap water, and a sewer so the drain line can
discharge hot waste water.
The Armstrong’s humidifiers have been developed to be hung on a wall. Before installation, make sure that the surface
material is strong enough to hold the humidifier. The humidifier performs best when the steam discharge is made at short
distance from the humidifier. Consider free space around the humidifier to allow easy access for maintenance purposes, see
the next drawing for the dimensions.
NOTE:
Please contact factory for duct applications offering high static pressure (>4” WC).
