Ducting To Hvac Systems; Recommended Hvac System Installation - Trane EDHUM070H Installation & Operation Instructions

Recommended HVAC System Installation

The recommended installation draws air from a dedicated indoor air return and ducts the supply of the
dehumidifier 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 EDHUM070H from a central area of the structure.
• Duct the supply of the EDHUM070H 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 EDHUM070H,
it is possible to select one to disconnect from the existing HVAC system and use it for the dedicated
EDHUM070H 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.
