INTERNAL MOUNT MARKING AND PREPARATION
1.
Each probe package is factory labeled for the specific location and duct size for which it is designed.
Orders for locations requiring multiple probes at a specific location are typically banded and packaged together.
Determine the specific duct location for the probe(s) as indicated on the engineer's plans showing where the
airflow measuring station is to be located. Refer to Figure 3 for probe spacing and orientation.
2.
Carefully open the probe packaging and inspect for damage. Proceed to the specific additional installation
instructions for rectangular ducts (at step 3), round ducts (at step 6) or flat oval duct applications (at step 9).
For Rectangular Ducts
3.
The first dimension of the probe size indicates the length of the probe. The second dimension indicates
the specific duct internal mounting inside dimension 'X' (including internal insulation). On ducts with internal
insulation that cannot be removed, adjust ‘X’ to equal the internal mounting inside dimension, minus two times
the thickness of the insulation. Refer to Figure 2 and verify that the probe is the correct size for the application
duct size. Mark a point on the center of the inside of the duct at ‘X’. Draw a line on the inside of the duct at this
point that is perpendicular to the edge of the duct. This line will be used to locate the position of the probe
mounting brackets. The probe quantity for the measurement site determines the probe installation
configuration/orientation as shown in Figure 3.
4.
Using the applicable Rectangular Duct Probe mechanical and spacing details of Figures 2 and 3, mark
the location for the cable exit end of each probe bracket at the location line(s) drawn in step 3.
5.
Mark the other corresponding end bracket (without cable) installation locations for each probe at the
opposite side of the inside duct wall.
Proceed to step 12, Final Assembly.
For Round Ducts
6.
Mark and draw a line around the inside circumference of the duct at the point where the probe brackets
are to be installed. The number of probes for this specific measurement site determines the probe installation
configuration and orientation as shown in Figure 3. Applications with multiple probes must be staggered 1.5 to
2 in (38.1 to 50.8 mm) from each other as shown in Round Duct Probe Spacing detail of Figure 4 to prevent
probes from intersecting at the center of the duct.
7.
Using the Round Duct Probe Spacing detail of Figure 3, locate and mark the individual probe
mounting location(s) on the circumference line drawn in step 6.
8.
Mark the non cable end bracket installation locations for each probe on the opposite side of the inside
duct wall.
Proceed to step 12, Final Assembly.
For Flat Oval Ducts
9.
Mark and draw a line around the inside circumference of the duct at the point where the probes are to
be installed. For oval duct applications, orientation is as shown in the Oval Duct Probe Spacing table and detail
application illustrations of Figure 3. Configuration ‘2b’, ‘3b’ and ‘4b’ probes must be staggered 1.5 to 2 in (38.1
to 50.8 mm) from each other in order to prevent probes from intersecting at the center of the duct.
10.
Using the Round Duct Probe Spacing detail of Figure 3, locate and mark the individual probe installation
location(s) for the cable exit end of each probe bracket on the circumference line drawn in step 6.
11.
Mark the non cable end bracket installation locations for each probe on the opposite side of the inside duct
wall.
Proceed to step 12, Final Assembly.
