Installation - Honeywell HE420A Manual

INSTALLATION

IMPORTANT
Read all the installation instructions before installing
the humidifier.
Select Location and Mount
There are three typical ways of mounting the steam
humidifier:
• horizontally under at least a 10 in. (254 mm) wide duct
using the mounting bracket (preferred mounting);
• horizontally under a reinforced duct;
• horizontally under a duct extension using the mounting
bracket.
Decide which mounting is appropriate and follow those
mounting instructions. See Fig. 2 through 4.
Select a location where the humidifier can be plugged in
without an extension cord. The preferred installation location
is on the warm air side of the furnace. If that location is not
possible, mount the humidifier a minimum of 6 ft (1.8m)
upstream from the furnace filter. Depending on the location
selected, additional duct reinforcement may be necessary
because the humidifier weighs 18 lb when filled with water.
