selecting a location
Consider these points as you choose the location for your
humidifier.
Locate humidifier on supply air plenum (Fig. 1) or return air pie-
num. If the humidifier is installed on the return air plenum, the flex­
ible hose, round opening, is connected to the supply air plenum.
If furnace is equipped with air conditioning, humidifier should be
mounted above or at slope side of “A” coil to avoid possible splash­
ing (Fig. 2) of water.
Humidifier should be installed so that if the humidifier or any other
connections should leak, the resulting flow of water will not cause
damage. Under no condition is Sears and the manufacturer to be
held liable for any water damage in connection with this humidi­
fier. Never install humidifier in attic or crawl space where freezing
may occur or leaking will cause water damage.
If holes between supply air plenum and return air plenum must
be located more than 40 inches apart (Fig. 1), standard 6 inch
round pipe and fittings (not supplied) may be used, or an 8 foot
section of flexible tube No. 28115205 may be purchased through
the Sears parts department Materials needed for this type instaF
lation are available at Sears.
