How humidifi ers work
A f fi n i t y
™
Whole-Home Humidifi ers use a natural
evaporation process to generate comfortable humidity.
Water fl ows through an evaporative pad and warm air
from the furnace is drawn through it. This creates the
pure water vapor that your HVAC system circulates
throughout your home for optimum comfort.

Model S1-BP4000MY
Large Bypass Water Saver Unit —
Patented technology uses 100% of
its water while holding less than
8 ounces of water in the system at
any given time. This eliminates the
need for a drain.

NOTE: Heat pumps — Model S1-BP4000MY can be installed in heat pump applications. However, due to the fact that heat pumps deliver lower temperature air to the
home than gas furnaces, evaporation will be approximately 60% of rated capacity. (With other Affi nity
™
models hot water can be used instead of cold to maximize
evaporation. However, due to the nature of the wicking water panel in the Model S1-BP4000MY hot water provides less benefi t.) As such, your dealer will need to take
the size and age of your home into consideration to ensure the Model S1-BP4000MY will provide satisfactory comfort and protection through adequate humidifi cation.
Model S1-BP5000MY
Small Bypass Unit — Designed for
smaller homes, using the HVAC
system blower to move air through
the humidifi er.

Model S1-BP6000MY
Large Bypass Unit — Larger
version of the small bypass
humidifi er using the same
evaporative technology.

Model S1-FP7000MY
Large Fan Power Unit — Uses an
internal fan to move warm air from
the furnace through the humidifi er.
18 gpd A. 15-29/32W x 18H x 10-11/32D

Model S1-STEAM8000T0I
Residential Steam Humidifi er —
For applications when evaporative
units are less practical (attics,
crawl spaces, closets, milder
winter climates, non-forced air
heating source).

the humidifi er.
Optional Automatic
Humidifi er Control available
• Monitors and automatically
adjusts humidity set point based
on inside relative humidity and
outdoor temperature.
• Green LED is a homeowner
notifi cation tool that indicates it’s
time to change the water panel.
