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.
