METAL DUCTWORK INSTALLATION
FIBERGLASS DUCTWORK INSTALLATION
• Locate a suitable area of the duct
for installation. Minimum 8" area.
If needed, cut away insulation to
expose metal duct.
• Mark location for 4" opening using
the included mounting plate as a
template.
• Cut opening for the device.
• Remove the backing from the
mounting plate gasket, center
mounting plate over opening, and
press onto the duct. The adhesive
gasket will hold the mounting plate
in place.
• Secure the mounting plate using self-
tapping screws.
• Insert device into opening and secure
with knurled nuts.
Note: Be sure airflow will pass in the
proper direction as indicated by the
arrow on the top of the core. (See
fig.3)
• Connect to proper power and test
operation. The operation indicator
light on the face of the device should
be on.
For fiberglass ductwork installations, follow metal ductwork installation
steps, but use 3" toggle bolts to attach mounting plate.
