IAQPoint User Manual
The IAQPoint Indoor Air Quality Monitor can be duct-mounted. It will
operate most effectively when the air speed is between 500-4,000 ft/min
(2.5-20.3 m/sec)*. It may be installed to monitor either incoming fresh air or
outgoing exhaust air. In order to optimize its operation, install the monitor
on a straight section of duct 3 feet (1 m) away from any curved ductwork.
Sampling Probe Assembly
The sampling probe is supplied in 3 parts: the base (1 piece), the sampling
probe sections (11 pieces) and the plug (1 piece). Before use, the
sampling probe must be assembled by snapping together the base, all 11
sampling probe sections, and the plug as shown in the illustration below.
(Two sampling probe sections are shown in the illustration.)

Before proceeding with the installation, verify that all sections have been
properly connected to create a solid sampling probe assembly.

1. Drill a 1.18 in. (3 cm) opening in the duct for the sampling tube.
2. Orient the lateral air holes to face the air flow and insert the
sampling tube into the opening.
3. Affix the octagonal plate to the duct.
4. Place a standard electrical box on the octagonal plate (orient
the box’s mounting holes vertically) and affix with two #8 metal
screws.
5. Screw the mounting plate onto the electrical box.
6. Connect the wire from the electrical box to the IAQPoint monitor.
7. Connect the power and outputs as shown in Wiring Details.
8. Verify that the sampling tube feeds into the appropriate port on
the back of the IAQPoint monitor. Press the monitor onto the
plastic base (the latches will click).
*Honeywell uses ft/min velocity rules but some industries and companies use cubic feet
per minute (CFM). To convert from CFM to velocity (ft/min), divide the flow by the area. For
example, in a 2 ft. x 4 ft. duct, where the area is 8 sq. ft., with an air flow of 30,000 CFM, the
air velocity would be (30,000 cu. ft/min)
÷
(8 sq.ft) = 3,750 ft/min.
