4.3.3 Install SMARThatch Sensor
Install gasket or sealing compound following drum manufacturer’s
recommendations.
The SMARThatch hatch adapter flange has slotted bolt holes on the top and
the bottom. At the nut location of the bottom slotted hole, partially install a
retaining bolt into the nut plate, engaging at least three threads and allowing at
least 3/8-inch (9.5 mm) gap between the bolt head and the outer drum surface
as shown in Figure 8.
With two (2) people, lift the SMARThatch sensor into position and in the correct
orientation. Slide the bottom slotted hole onto the installed bolt to help support
the weight of the sensor during installation as shown in Figure 9.
Install the remaining retaining bolts and tighten following the drum
manufacturer’s recommended procedure.
Warning
WARNING: The SMARThatch Sensor is heavy (56 lbs / 25 kg) and
can cause serious injury if mishandled or dropped. Two (2) people
