Introduction
Installation Instructions
Duct-mount Installation
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)
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. 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.
