Insertion Mounting Bracket Probe Installation

The installation objective is to install probes so that the probe sensor center location is at the exact position in the
duct/plenum as shown in Figure 6 (for single probe model GF-A2100) or Figure 7 (for two-probe model GF-A2200).

For the duct/plenum probe insertion point mark, measure and record the duct/plenum height at the side where

the probe is to be installed as shown in Figures 5 through 7. At 1/2 of the measured duct/plenum height, mark the
probe insertion point on the duct/plenum to ensure that when the probe is inserted, its sensor center location will
be at the exact position in the duct/plenum as shown in Figure 6 (for GF-A2100) or Figure 7 (for GF-A2200)

For single probe model GF-A2100:

For the probe insertion depth mark, refer to Figures 5 and 6. Calculate and record the sum of (1

1/2 of dimension ‘D’

+ 3 inches {76.2 mm} + insertion wall insulation thickness). Measure from the non-cabled end of the probe and
mark the probe across the factory score line at this point. This will serve as the probe insertion mark.

For two probe model GF-A2200:

For the probe insertion depth mark, refer to Figures 5 and 7. Calculate and record the sum of (1

1/4 of dimension ‘D’

+ 3 inches {76.2 mm} + insertion wall insulation thickness). Measure from the non-cabled end of each probe and
mark each probe across the factory score line at this point. This will serve as the probe insertion mark.

Prepare the probe insertion hole(s) (one for the GF-A2100, two holes for the GF-A2200) at the location(s) marked

in step 1 using a 0.875 inches (22.2 mm) hole saw.

Temporarily slide the probe and bracket through the hole prepared in step 3 so that the airflow label on the brack-

et is parallel to and in the same direction of duct/plenum airflow. Mark the four mounting bracket hole locations for
each probe.

Remove probe from duct/plenum and then prepare suitable mounting holes for the field supplied hardware that

will be used to secure the mounting bracket.

Slide the gasket seal down the probe body to the bracket. Carefully position the probe in the insertion hole pre-

pared in step 3 so that the airflow label on the bracket is aligned with the actual airflow in the duct/plenum. Insert
the probe so that the probe insertion depth mark (step 2) is just visible at the insertion mark target on the nylon
bracket block. Secure the probe at this location using the setscrew on the mounting bracket nylon block. (Refer to
Figures 5 and 7 for detail).

Ensure that the edge of the probe mounting bracket is parallel to the edge of the duct, and that the airflow arrow

printed on it is oriented in the same direction as duct/plenum airflow. Secure the probe mounting bracket at the four
holes prepared in step 5 using suitable hardware.

For two probe model GF-A2200, repeat steps 4 through 7 for the remaining probe supplied.

Route the sensor probe cable(s) to the transmitter location.
