Ultra-Aire 100V Installation Instructions
www.Ultra-Aire.com | 1-800-533-7533
Fresh air ventilation is optional.
Fresh air may be brought into the structure by connecting an insulated duct from outside the structure to
the 6" inlet of the Ultra-Aire 100V. A ventilation control is needed to program the time and frequency that
the unit introduces outside air. The time and frequency of ventilation should be based on the size and
occupancy of the residence.
• The fresh air ventilation duct should be connected to the 6" round collar on the front of the Ultra-Aire 100V.
• An insulated 6" diameter duct provides up to 75 CFM of outside air.
• If a motorized damper is not being used, fresh air is controlled by the manual damper in the 6” collar of the
Ultra-Aire 100V.
• Performance of the Ultra-Aire 100V can be impacted by inside and outside air conditions.
• When a 6" motorized damper is used, a digital control is required.
• It may be necessary to use 8" duct work if additional fresh air is required.
• In cold climates or at times when the dew point is low, ventilation can be used to dehumidify the
structure, making the Ultra-Aire 100V capable of year-round drying.

Fresh Air Ventilation With Dehumidifier Off and Fan Only Operation
Outside air mixes with the dehumidifier’s
return air before being supplied to the
home. Outside temperature, inside
temperature and relative humidity
will impact the combined outlet
air conditions.
Note: Temperature and relative
humidity may vary depending on
duct distribution scheme.
