Insert four ½-12 mounting studs so that the inside threaded portion is completely threaded into the motor frame. This will set
the mounting stud to the correct length. Torque the mounting studs to a nominal 60 ft-lbs. The mounting studs support the
weight of the enclosure during installation, permit better alignment to the motor, and prevent the Pulse Wheel from being
damaged.
Remove enclosure from packaging.
Determine which of two orientations of enclosure is best for this application (Sensor Modules horizontal or vertical).
Ensure that one of two drain holes is at bottom of enclosure. If not,
rotate the unit 180°.
Place enclosure on rods and slide on to motor facing. Tap lightly with hand or hammer if needed to start enclosure to slide
over motor facing. Make sure clearance holes remain aligned.
Using a straight edge, align the pulse wheel so that the front edge of the pressure plate is even with the recess of the enclosure.
See figure 7.
Once the pulse wheel is aligned, tighten the screws in a star pattern to 30 inch-pounds.
Do not attempt to mount or dismount the enclosure with sensor probe module(s) installed. Remove all
sensor modules until enclosure mounting is complete
Insert four 1/2-13 cap nuts onto the remaining exposed mounting studs. Tighten the nuts in an alternating star pattern.
Continue alternating and tightening until enclosure is seated. Torque all cap nuts to a nominal 50 ft-lbs.
