Recommended HVAC System Installation
DUCTING TO HVAC SYSTEMS
The recommended installation draws air from a dedicated indoor air return and ducts the supply of the
dehumidier to the air supply of the existing HVAC system. Utilize the optional fresh air ventilation duct to
provide outside 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 existing 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 dehumidier and placed in a central location.
