Enclosure Replacement
12-26 Service Manual
18. Install the three pole clamp mounting bolts in the rear enclosure by placing each
bolt into its mounting hole and pressing downward until fully seated. (See
Figure 12-12 on page 12-16 for location.)
19. Install the pole clamps on the mounting bolts as follows (Figure 12-19 on
page 12-24):
a. Turn the enclosure over.
b. Slide a clamp foot onto each bolt, making sure that the rubber pad is toward
the unit.
c. Place a knob on each bolt and tighten it until the clamp foot is secure. Do not
overtighten.
20. Turn the enclosure over and remove the tape and packing material from the
heater cone. Make sure that the heater cone and screen are positioned as shown
in Figure 12-22:
• The notches at the bottom of the cone should fit over the three mounting
screw bosses. The top edge of the cone should be even with the enclosure
inside surface.
• The screen should lie flat at the bottom of the cone, with the cutouts in the
screen aligned with the mounting screw bosses.
