Installation Guide

To wire and duct-mount the sensor

Duct installation requires the Aspirator Box Accessory (Part #33ZCASPCO2) to house the CO

sensor.

To mount the aspirator box and sensor:

Drill a 1.25 inch (3.18 cm) hole in the return duct.

Remove the aspirator box cover.

Insert the aspirator box sampling tube into the hole.

Secure the box to the duct using 2 field-supplied #8 x 1" sheet metal screws.

Remove .5 inch (1.3 cm) conduit knockout, then install the conduit fittings.

Mount the CO

sensor in the aspirator box using 2 field-supplied #8 x 32 machine screws.

To wire the CO

sensor, see the instructions above in

To wire and wall-mount the CO

sensor

(page 45).

Install the aspirator box cover.
