Figure 70: Drill Holes Mounting Locations
• Use the sensor as a template to locate and mark the
mounting holes.
• Locate the field provided duct pressure tap near the end
of a long duct to ensure that all terminal box take-offs
along the run have adequate static pressure. The tap
should be in a non-turbulent flow area of the duct. Keep it
several duct diameters away from take-off points, bends,
neckdowns, attenuators, vanes, or other irregularities that
may create turbulent air flow.
Figure 71: Sensor Location In Supply Duct
• Mount sensor on the supply duct near the location
selected for the duct pressure. See
IM 1267-7 • PRECISELINE AIR HANDLER
Figure 72: Secure Sensor with Provided Screws
Connect the wires to the sensor as follows: See

• Run 3-conductor wire from the sensor location to the unit.
Daikin Applied recommends using shielded 22AWG for all
connections. Larger gauge wire may be required for runs
of greater than 250'.
• Connect the field provided tube between the tap and the
high pressure (H) port on the sensor.
• The sensor has internal setting options. For proper
operation the setting must be as follows: Also refer to
Figure 74.
► OUTPUTS = 0-10 Volts
► RANGES = 3.0"/1,000PA
► UNITS/RESPONSE
#1: Direction = OFF = Unidirectional
#2: WC or Pascales = OFF=Inches
#3: Response Time = OFF=Slow
