DUCTING TO HVAC SYSTEMS
8
b. Installation in a Basement or Crawlspace
Install a separate 8" return for the Ultra155/205 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 Ultra155/205 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 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. If this is of concern, a power damper is
suggested.
