2.
Check Local Codes
EHU-600 Series humidifiers should be installed in accordance with
all applicable building, plumbing, and electrical codes.
3.
Site Selection (See Fig. 3-1)
Electronic steam humidifiers should be installed in locations that
allow routine inspection and accessibility for maintenance opera-
tions. Armstrong recommends that electronic steam humidifiers
not be placed in false ceilings or in locations where unusual
instances of malfunction of the humidifier or the system might cause
damage to non-repairable, unreplaceable, or priceless property.
Note: Please contact factory for duct applications offering high static pressure (>4" WC).
