pulley set screw with a 4 mm Allen wrench to
110 inch pounds of torque.
6.6 Position the front of the pulley so that it touches the
Alignment tool as seen in Figure 5 and Detail B. (If
necessary, tap lightly on front of shaft with rubber
mallet).
6.7 Tighten the Allen (set) screws on the bearings to 70
inch pounds of torque. IMPORTANT: Use Lock-Tite

6.8 For a metal fan blade skip to Step 6.10. For a Fiberglass fan blade, place the Trans Torque Bushing
(1047-7001) over the front of the fan blade as shown in Figure 6. Then insert the fan blade onto the
bearing shaft flush and tighten with a 1½” socket to 94 foot pounds of torque as shown in Figure 7.
6.9 For a Standard Metal Prop refer to Figure 8.
Place the Blade Assembly flush with the shaft.
Tighten the bolt with a 9/16“ socket to 110 inch
pounds torque.
6.10 Refer to Figure 10. Place the Pulley Assembly
36”(1101-9003) 48&52” (1011-9005) in front of the
Tension Bracket 36”(0403-5522) 48&52”(0403-4891)
and fasten with 3/8” X 1” hex head bolt (1004-1426)
and hex head washer/screw (1004-6020). Tighten
the bolt with a 9/16 “ socket and the screw with a 3/8 “
socket.
6.11 Place the Pulley Assembly under the top brace as
shown in Figure 11 and attach with six 1/4” x 3/4” hex
head bolts (1004-5017), six 1/4” flat washers (1003-
0108) and lock nuts (1001-0104) using a 7/16“
socket.

6.12 Now remove the Pulley Alignment tool from the
top brace and check the alignment of the
bearings. Straighten the bearing to be
perpendicular to the shaft and tighten securely.
6.13 Place the Bracket Assembly and place into the
Fiberglass shroud 36" (4003-3002) 48" (4003-
3003), 52" (4003-3001), as shown in Figure 12.
Note the two drainage holes at the bottom of
the shroud.
6.14 With the shroud lying flat on the floor, attach a
Fan Alignment Jig on the end of each blade as
shown in Figure 13. Now carefully spin the fan
and align the four bracket arms so that the fan
blade does not touch the shroud. This will
provide a 3/16” clearance between the fan blade
and the shroud. (Note: in some cases the
alignment tool may slightly touch the housing,
but should allow the fan to be rotated freely.)
6.15 While rotating the fan blade, the bracket arms
should be lined up so as to center into their
respective corners. See Figure 12.
6.15 Refer to Figure 15. Firmly hold the bracket arms in
position and drill a hole through the fiberglass shroud
using a 21/64“ drill bit (at least 5“ long) using the
hole in the side of the bracket arm as a guide.

6.16 Refer to Figure 16. Fasten arms to shroud with 5/16” x 7/8” hex head bolt (1004-5000) and
5/16” x 1½” fender washer (1003-2604) from the outside of the shroud. Use 5/16” x ¾” flat
washer (1003-0103) and lock nut (1001-0103) as shown.
6.17 Refer to Figure 17. NOTE: The 36” fan does not require a gusset. For the 48” & 52” fans, install the
gusset (0403-4892) using the proper mounting holes using 5/16" cap screw (1004-5000), two washers
(1003-0103) and lock nut (1001-0103). Level the gusset and drill four holes through the shroud.
Fasten the gusset to the top left corner of the cabinet using six ¼” cap screws (1004-5017), twelve
5/16” x ¾” flat washers (1003-0103), and six lock nuts (1001-0103).
6.18 Remove the three Fan Alignment Jigs placed on the ends
of the fan blades in Step 14.
6.19 Install the two Tension Latches (1040-0105) and Latch
plates (0403-6756) on either side of the shroud using 3/16”
rivets (1005-1469). See Figure 18.
6.20 At this point the fan housing can be installed in the wall
before completing the rest of the installation steps.
6.21 Install the motor in the top mounting holes as
shown in Figures 19, 20 and 21 using four
carriage bolts (1002-2818), and lock nuts (1001-
0103). Before tightening bolts, push the motor all
the way up the mounting arm to give the proper
tension on the belt.

6.22 Refer to Figure 22. Install the motor pulley with the set
screw facing outward. Install the shaft key (1019-2417)
into the pulley. Do not tighten at this time.
6.23 Install the belt as shown in Figure 22 and align the motor
pulley to the fan and idler pulleys by using a straight
edge as shown in Figures 23 and 24. Hold the straight
edge so that the edge touches the pulleys at four places.
Perform the alignment twice, once above the shaft level
as in Figure 23 and once below the shaft level as in
Figure 24.
6.24 Tighten the motor pulley set screw to 110 inch pounds.
