DUCTING TO HVAC SYSTEMS
b. Installation in a Basement or Crawlspace
Install a separate 8" return for the Ultra70 in a central area of the structure. Duct the supply of the
dehumidifier to the air supply of the HVAC system with a backdraft damper.
Optional:
Duct the supply of the Ultra70 to a 8" x 8" x 8" tee/damper with a gravity draft damper, adjusted
to 20% open to the basement. CAUTION: Air takes the path of least resistance. If the upper levels of the liv-
ing space are not receiving the appropriate amount of dry air, this damper may need to be adjusted. When
the dehumidifier is not running, there is a chance that air from the basement or crawlspace will make its way
back through the gravity damper and into the living space.
