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 120V. 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" damper on the top of the Ultra-Aire 120V.
• An insulated 6" diameter duct provides up to 100 CFM of outside air.
• If the fresh air ventilation duct is to be used, the return of the Ultra-Aire 120V must be ducted or an inline
fan may be required on the fresh air ventilation line to bring in 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 120V.
• Performance of the Ultra-Aire 120V 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 120V capable of year-round drying.
FRESH AIR VENTILATION
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.
