Recommended HVAC System Installations
a. Attic
The recommended installation draws air from a central location through a dedicated return to the
dehumidifier and ducts the supply of the dehumidifier to the air supply of the HVAC system. Utilize the
optional outdoor air ventilation duct to provide outdoor air.
•
Install a dedicated 8" air return for the Santa Fe Ultra70 from a central area of the structure.
•
Duct the supply of the Santa Fe Ultra70 to the supply of the HVAC system with a backdraft damper.
•
If the existing system has multiple returns, instead of installing a dedicated return to the Santa Fe
Ultra70, it is possible to select one to disconnect from the existing HVAC system and use it for the
dedicated Santa Fe Ultra70 return. Select a return from a central location in the house that is always
open to the rest of the structure. DO NOT use a return from a room where doors are kept closed.
•
DO NOT locate return in a bathroom or kitchen.
•
Control should be located remotely from the dehumidifier and placed in a central location.
