Universal Mounting Bracket Probe Installation
The installation objective is to install probes so that the probe sensor center line is located at the exact position in
the duct/plenum as shown in Figure 4.
1.
Sensor probes must be installed at the factory-specified location using the integral universal bracket attached as
shown in Figure 3. The universal bracket consists of a rubber probe clamp that is attached to the bracket using the
included hardware. Probes can be rotated within the clamp, and the clamp can be rotated and mounted at any point
along the 4-inch slot on the mounting bracket, thus providing complete mounting flexibility and adjustment.
Assemble probe to the clamp and bracket so that when mounted, air flow is through the probe sensor opening, and
in the same direction printed on the probe label.
2.
Using the engineer’s plans, mark the two mounting holes for each probe bracket at the GreenTrol factory-speci-
fied location where the probe(s) will be installed.
3.
Drill holes suitable for the hardware that will be used to secure the bracket at two locations.
4.
Carefully align the bracket mounting holes with the holes prepared in the previous step.
5.
Secure each probe bracket and probe in two places through each bracket using suitable hardware. Adjust each
bracket mount and/or probe clamp so that the airflow arrow printed on the probe is oriented in the direction of actu-
al airflow.
6.
Route each sensor probe cable to the planned transmitter site and install transmitter as outlined in the TRANS-
MITTER INSTALLATION procedure that follows.
