Installation Instructions for the Innovair™
CD100DH Duct Housing.

1. Overview

1.1 The mounting
location should be in
the return air duct.
Find a location that
will allow easy
access for modifying
or calibrating the
sensor .

2. Box Preparation

2.1 Remove the box cover by unscrewing the four
plastic screws.

2.2 For optimum sensing, the three holes located
on the inlet tube must face the duct air flow. If
the three inlet holes are facing the wrong
direction, simply turn the tube while making
sure the box is in the correct orientation.

Screws (4)

3.5 Using the four mounting screws (provided)
secure the sensor mounting bracket to the
four stand-off posts in the aspiration box.

3.6 During wire installation, use caution while
routing the wires through the box. Strip the
wire insulation approximately 1/4" and ensure
the exposed wire is free of loose strands.

5. Sensor Removal

5.1 Remove the plastic cover.

3.7 Make the necessary wire connections by
following the pin designations on the terminal
block label. Insert the wires into the terminal
block and seat the wire insulation flush
against the terminal blocks. When wiring is
complete check for any wiring that may be
touching adjacent wires or terminal blocks.

3.8 For proper operation, it is important to maintain
an airtight seal within the duct housing. If any of
the “knockouts” were modified for wiring,
confirm that the opening is properly sealed with
caulk or putty.

4. Sensor Installation

4.1 The sensor can now be installed. First, mount
the top of the sensor to the top of the plastic
mounting plate and then firmly press the lower
half of the sensor into place.

5.2 The sensor is hinged at the top and fastened at
the lower end. To remove the sensor pull from
the bottom of the sensor and lift outward. The
sensor fits snugly into place, removal may
require a hard pull.
