DUCTING TO HVAC SYSTEMS

Alternative HVAC System Installations

If the Recommended Dedicated Ultra-Aire Return to HVAC Supply Installation is not possible, there are several 
alternative installation options available.
•  DO  NOT locate return in a bathroom or kitchen.
•  Control should be located remotely from the dehumidifier and placed in a central location.

Create a separate return for the Ultra-Aire 
SD12 in a central area of the building.
 Installing the supply air from the Ultra-Aire 
SD12 in the return of the HVAC system 
requires the HVAC fan to run when the 
Ultra-Aire SD12 is operating.
