DUCTING TO HVAC SYSTEMS
8
b. Installation in a Basement or Crawlspace
Install a separate 8" return for the Ultra120V 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 Ultra120V to a 8" x 8" x 8" tee/damper with a gravity draft damper, adjust-
ed to 20% open to the basement. CAUTION: Air takes the path of least resistance. If the upper levels of the
living 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.
