General
The HCSteam−16/−35 humidifier produces non−pressur-
ized steam which is then used to humidify the air.
The quality of the water used affects the operation of this
unit, so the humidifier may be supplied with untreated wa-
ter, as long as it is drinkable and not softened or demineral-
ized. The water converted into steam is automatically re-
placed through an electric fill valve. Periodically, based on
the water quality, the unit will also drain some water to di-
lute the build−up of minerals in the steam generator.
This humidifier has been designed to directly humidify
ducts using a distribution system. The installation, use and
maintenance operations must be carried out according to
the instructions contained in this manual and on the labels
applied internally and externally.
Disconnect the humidifier from the main power supply be-
fore accessing any internal parts.
The conditions of the environment and the power supply
voltage must comply with the specified values listed on the
data label in the humidifier.
All other uses and modifications made to the humidifier
that are not authorized by Lennox are considered unautho-
rized, and Lennox assumes no liability for the conse-
quences of any such unauthorized use.
Please note that the humidifier contains powered electrical
devices and hot surfaces.
NOTICE
The humidifier requires water to operate.
Do NOT mount it above materials or machinery that
could be damaged if a leak occurs. Lennox assumes
no responsibility for consequential or inconse-
quential damage as a result of any leaks.
If unit must be located where any leaking water
could cause damage, an auxiliary drain pan is rec-
ommended.
Disposal of humidifier parts
The humidifier is made up of metallic and plastic parts. All
parts must be disposed of according to the local standards
on waste disposal.
