INSTALLATION, WIRING & CONFIGURATION
1. Plan the installation. Panel or duct mount?

INSTALLATIONS
NOTE: Velocity measurement, shown below, requires the use of a pressure-velocity pick up tube, part P7650L6,
P7650L8, P7650L10, P7650L12, or P7650L14. Length is the number after L in inches, so P7650L6 is 6 inch,
etc. See form 31-00149 for details on installing and configuring the P7650L velocity pick up probes.
2. For duct mount applications, thread the probe into
the back of the device housing, as shown in the
dimensional drawing.
3. Configure the internal tubing for the selected instal-
lation method as described below.
Duct mount tubing configuration:
a. Connect the right-side tube to the rear brass
barb marked as "-" on the underside of the device
housing.
b. Connect the left-side tube to the probe in the
back of the device housing.
Panel mount tubing configuration:
a. Connect the right-side tube to the rear brass
barb marked as "-" on the underside of the device
housing.
b. Connect the left-side tube to the front brass barb
marked as "+" on the underside of the device
housing.
