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 10" air return for the Dehumidier from a central area of the structure.

• Install an insulated duct from outside to the 6" collar of the Dehumidier to provide fresh air

ventilation (optional).

• Duct the supply of the Dehumidier 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

Dehumidier, it is possible to select one to disconnect from the existing HVAC system and use it for the

dedicated Dehumidier 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.

• Please visit our website at www.Broan-NuTone.com for more installation options.
