Spot Dehumidifier Installations:
Installation in a Sealed Crawl Space or Sealed Attic
When installing the Comfort-D in a sealed crawlspace or sealed attic, a single re-
turn for the Comfort-D should be installed in the central open area of the structure�
If the area is open without partitions, return ducting is not necessary� Supply duct-
ing is recommended to enhance the performance of the system, a minimum length
of supply duct, 3’ to 6’ will aid in air distribution. If the area(s) being served are
divided by walls or partitions, a supply and return duct system is recommended�
In all cases, sound duct design practices must be followed such as those provided
in ACCA Manual “D”, or ASHRAE’s “Fundamentals of Air System Design”.
