Figure 3-55 Installing a differential pressure sensor
Step 2 Connect the longer PU hose to the port without the Lo (-) silk screen under the
differential pressure sensor, and route the hose through the top of the cabinet to
the supply air pipe static pressure box. (There should be two binding points
adjacent to the pressure inlet. The distance between the binding point closer to
the pressure inlet and the pressure inlet should not exceed 25 mm, and the
distance between two binding points is within 20–30 mm). You do not need to
connect the other port on the pressure differential sensor to the PU hose.
● You do not need to connect the other port on the pressure differential sensor to
the PU hose.
● The pressure tube of the differential pressure sensor passes through the middle
of the thermal insulation foam close to the inner side of the cabinet.
