1. Cut a 1/2 in. (13 mm) hole in the duct or plenum surface
at the desired location.
2. Insert the sensor probe into the duct or plenum hole
until the flange rests against the duct or plenum wall.
3. If necessary, use the flange as a template to mark and
drill two holes for no. 8 mounting screws.
4. Fasten the sensor to the duct or plenum surface with
the two no. 8 sheet metal screws (not provided).
To mount the C7046C Sensor in a junction box (see Fig. 11):
1. Cut a 1/2 in. (13 mm) hole in the duct or plenum surface
at the desired location.
2. Remove the center rear knockout from the junction box
and insert the sensor probe through the knockout with
the flange flat against the junction box.
3. Using the flange as a template, mark and drill two holes
in the junction box and the duct or plenum surface for
no. 8 mounting screws.
4. Insert the sensor probe through both the junction box
knockout and the 1/2 in. (13 mm) hole drilled in the duct
or plenum and fasten the junction box and sensor to the
duct or plenum surface with the two no. 8 sheet metal
screws (not provided).
