Features and Benefits
The Honeywell DH90 Whole House Dehumidifier is designed to provide
ultimate indoor air quality. The DH90 provides the three key components
of healthy indoor air: fresh air ventilation, particulate filtration and
humidity control. At the heart of the DH90 is a high capacity, energy
efficient dehumidifier capable of removing over 90 pints (11.2 gallons) of
water per day (at 80°F, 60% relative humidity), while using only 6.2 amps
of electricity (120V). This allows the unit to maintain indoor humidity
levels below 50%, the level widely recognized as critical for controlling
mold and mildew.

Operating Instructions
How do I set the humidity level?
The DH90 dehumidifier is controlled by the Honeywell H8908
dehumidistat. The dehumidistat sets the humidity level within
the home much like a thermostat sets the temperature. Set the
dehumidistat to your comfort level. A typical setting of 30 should
keep the home comfortable for most. If the home is too dry, set the
dehumidistat to a higher level. If the
home is too damp, set the dehumidistat
to a lower level. There is also a chart
on the front of the dehumidistat that
lists recommended settings based on
the outdoor temperature.
