OUTDOOR AIR VENTILATION

10
Outdoor air ventilation is optional.
Outdoor air may be brought into the structure by connecting an insulated duct from outside the structure to the
6" inlet of the Santa Fe Ultra98/120. 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 outdoor air ventilation duct should be connected to the 6" round collar on the front of the Santa Fe
Ultra98/120.
• An insulated 6" diameter duct can provide up to 75 CFM of outside air.
• If a motorized damper is not being used, outdoor air is controlled by the manual damper in the 6" collar
of the Santa Fe Ultra98/120.
• Performance of the Santa Fe Ultra98/120 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 outdoor 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 Santa Fe Ultra98/120 capable of year-round drying.

and inside temperature and relative humidity will impact the combined outlet air conditions.
