Recommended HVAC Ducting Installations
The recommended installation draws air from a dedicated indoor air return and ducts the supply of the
dehumidifier to the air return of the existing HVAC system. Utilize the optional fresh air ventilation duct to
provide outside air.
• Install a dedicated 10" air return for the Envirowise XT155H from a central area of the structure.
• Install an insulated duct from outside to the 6" collar of the Envirowise XT155H to provide fresh air
ventilation (optional).
• Duct the supply of the Envirowise XT155H to the return side of the existing HVAC system with a backdraft
damper. HVAC system interlock is recommended.
• DO NOT locate return in a bathroom or kitchen.
• The optional D30 or a system thermostat control with integrated Dehumidification software should be
located remotely from the dehumidifier and placed in a central location.
Attic Installation -
Dedicated Return to HVAC Return
Duct the supply of the Envirowise
XT155H to a 10" x 10" x 10" tee
damper that is 20 percent open
to the basement/crawl space.
Basement/Crawl Space Installation -
Dedicated Return to HVAC Return
Positive Pressurization of crawl
spaces with dehumidification
added could potentially bring
unwanted, unhealthy air into
living spaces. The recommended
application with dehumidification
added is to achieve neutral
pressure in crawl spaces.

HVAC system fan interlock is recommended to
reduce potential comfort issues with this application.
Create a separate return for the
Envirowise XT155H in a central
area of the building.
Installing the supply air from
the Envirowise XT155H to
the return of the HVAC system
requires the HVAC fan to run
when the Envirowise XT155H
is operating.
