Connecting to the Exhaust System
WARNING: The weight of the exhaust ductwork system must be
supported independently of the superstructure or damage may occur.
The exhaust system should be installed by a qualified HVAC contractor.
The exhaust connection on the Demonstration Hood has been designed to
accept a 2" x 10" (5.1cm x 25.4cm) nominal transition adapter. See Chapter
7 for ordering accessory transition adapters. Labconco manufactures
transition adapters for either top or bottom exhaust and for both 5" dia. hose
or 6" dia. duct. Review Chapter 2 for remote blower and FilterMate Portable
Exhauster exhaust prerequisites and review Chapter 7 for ordering blower
exhaust equipment. For your convenience several exhaust options are shown
in Figures 3-2, 3-3, 3-4, 3-5 and 3-6. Consult Labconco Customer Service
should you require help sizing your blower for the exhaust volume and
system static pressure loss.
