Installation & Operation Instructions
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
dehumidier 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 dehumidier and placed in a central location.
