between 2 joists.

Installation/Service/Owner's Manual
Always mount the fan to 2 joists. 1 joist will not
provide the rigidity and support necessary for the
fan during operation, and may cause the fan to fall
and cause injury.
Toujours monter le ventilateur sur deux solives.
Une seule solive n'apportera pas la rigidité et le
soutien nécessaire au ventilateur en marche; cela
pourrait entrainer la chute du ventilateur et causer
des blessures.
1. Lay (2) 120 in (3050 mm) long struts on the lowest
angle of an open‑web roof structure.
2. The open side of the strut (A) is up and the
2 in (51 mm) slotted holes are down. The strut
brackets (B) will automatically space the struts
8 in (203 mm) on center (C).
3. Install washer and nylon lock nut (G). Install the bolts
(D) with washers up through the spacer plate (E), joist
angles (F), strut, and strut bracket. Repeat on the
opposite end of the strut. Tighten hardware.
4. Install the drop brackets (H) at any point along the
pair of struts and between the joists. Attach the
spacer plate and hardware as described. Leave at
least 3 in (76 mm) between the brackets. DO NOT
tighten.
5. If equipped with a extension tube (I):
a. Attach the extension tube to the drop brackets. Use
(2) 1/2 in x 4.5 in bolts, washers and nylon locking
nuts.
b. Attach the enclosure brackets (J) to the opposing
face of the extension tube. Use (2) 1/2 x 1.5 in
bolts with nylon lock nuts.
6. If no extension tube is present, attach the enclosure
brackets (J) to the drop brackets. Use (4) 1/2 x 1.5 in
bolts with nylon lock nuts.
7. Tighten all nylon lock nuts.
8. Plumb the unit by adjusting the lower nuts and upper
nylon lock nuts. Use a bubble level in both directions.
9. After enclosure is in place, install safety cable:
a. Slide the safety cable clamp (K1) onto the safety
cable (K2).
b. Route the safety cable through the extension tube
(when present), around the strut, and secure with
the safety cable clamp.
c. Wrap extra cable and secure with a tie band or cut
to length.
