18. To complete the last flange connection, roll the cone panels so
the small end is on the floor. See Figure 6. IMPORTANT! The
four pilot holes should be at the top end on the outside of the
cone.
19. Mount cone to fan. Bend the mounting
brackets back slightly to help clear the area
of the cone edges. Hang the centered slot
in the small end of the cone over the Pim
screw mounted on the Fan housing. See
Figure 8. Screw can be fastened with ¼"-
20 lock nut, if necessary (not included).
20. Align the cone over the remainder of the fan
housing. Using four 1/4"-20 Truss Head
Phillips bolts and 1/4-20 lock nuts, insert the
bolts from the inside of the cone. See Figure
9.
21. Mount the Damper Ring. Ring is mounted in the holes closest to the
orifice on the top and farthest away from the orifice in the bottom. Use
¼-20x1" bolts, nuts and washers (provided) to attach ring to cone.
Washers go on outside of cone. See Figures 10 and 11.

guard is shipped with a cut-out for a 1.0 Hp 3Ph motor. The cut-
outs for this motor is shown in Figure 14A. If you are using a
1.5 Hp 1Ph Motor, cut the hole as shown in Figure 14B. If you
are using a 1.0 Hp 1Ph Motor, cut the hole as shown in Figure

25. Assemble the Inlet Frame using 12 rivets (1005-1464).
See Figure 15. Place the Screen Guard into the opening
and bend the 12 tabs over the screen wire. See Detail A.
26. Install the Fan Inlet Frame with Wire Guard by
lifting the bottom into the slot at the bottom of

opening hole for the motor. Use two spring
latches on either side of the fan housing to
secure the Inlet Frame. See Figure 15.
27. There are two unused holes in the bottom of the
cone. For reference refer back to Figure 10. Place a
3/8” bolt and nut in these holes to prevent light from
passing through. See Figure 16.
28. There are two pre cut drain holes in the bottom of the fan
housing in either corner and one in the bottom center of
the cone. These may be opened if necessary. See Figure
16.
29. Affix labels to fan as shown in Figure 17.
