INSTALLER'S & OWNER'S MANUAL
HVAC INSTALLER: PLEASE LEAVE MANUAL FOR HOMEOWNER
The Ultra-Aire 90H dehumidifier performs multiple functions in
a compact enclosure; high-capacity dehumidification, fresh air
ventilation, and particulate filtration.
Dehumidification
The highly efficient UA-90H dehumidifier utilizes refrigeration to cool
the incoming air stream below its dew point. This cooled and drier
air is used to pre-cool the incoming air stream resulting in increased
overall efficiency. After the pre-cooling stage the processed air is
reheated by passing through the condenser coil. The heat removed
by the evaporator coil is then returned to the air stream.

Fresh Air Ventilation (optional)
Fresh air may be ducted to the unit and regulated by a variety of
controls in order to provide desired ventilation rates.
Air Filtration
The UA-90H includes particulate filtration to improve the indoor
air quality of your living/working space. MERV-11 media filter is
standard.
