NOTICE
Fan Pack must be installed over drywall for proper operation.
The Fan Pack must be located near the Steam Humidifier to minimize
the length of the steam hose. If the Fan Pack is mounted directly
above the humidifier, 16” is required for the steam hose to make the
bend. See Figure 2.
Six feet of steam hose is provided with the Steam Humidifier. For
installations that require longer runs, a combination of the steam
hose and insulated copper pipe can be used. See Figure 3. When
using more than 24” of steam hose or 36” of insulated copper pipe,
install a Drain Tee and Trap (#4028) to help control condensate and
reduce gurgling. See Figure 5.
Due to condensation inside the hose or pipe, the output of the Fan
Pack depends on the length of the steam hose or pipe connecting it to
the Steam Humidifier. See the Steam Humidifier installation manual
for maximum steam capacity (gal/day).
Humidity behaves like a gas and under ideal conditions will expand to
fill the space. However, air movement due to drafts or as a result of
temperature stratification may cause uneven distribution of humidity
within the conditioned space. To ensure even RH distribution, install
system in a central location.
To prevent condensation on surfaces and furnishings, install the fan
pack so the steam being discharged has enough room to be absorbed
into the air before encountering surfaces.
