Ducting: Install to Fit Your Application

Flex duct is recommended in connecting to the TrueDRY DH150 collars to reduce vibration noise.
Duct Sizing: For total duct lengths, use round or rectangular duct sized accordingly:
- 10-inch for less than 25-ft
- 12-inch for more than 25-ft
For the optional fresh air ventilation port, use round insulated duct sized accordingly:
- 6-inch round for lengths of less than 50-ft.
- 8-inch round for lengths greater than 50-ft, or if more than 100-cfm is required
TrueDRY DH150 can be ducted into the central forced air sys-
tem, or operate as a stand-alone in designated, high-humidity
zones within the home, such as a basement or crawl space.
