Fan Installation 48'' Belt Drive Cone Fan
8MV1600B
Important! The 48'' Cone Fan must be installed in a side wall.
Build fan framing out of 2'' [50 mm] lumber (not supplied). The required rough
opening is provided in the table below.
Insert the Fan Assembly in the framed opening in the side wall
Center the Fan Assembly in the framed opening, left to right. Allow the Fan Housing
to set on the bottom of the framed opening.
Secure the Fan Assembly to the framed opening, using the included 1/4'' x 1-3/4'' Lag
Screws starting with the center holes in each panel. The end holes will also be used
for attaching the Corner Flange Angles.

Planning the layout of the spacing between Cone Fans is very
important. SPACING TO CLOSE TOGETHER WILL CAUSE
INTERFERENCE with the cones.
Allow a minimum 4'' spacing between framed openings for adjacent
fans. This will provide clearance for the mounting flange.

The Cone must be assembled and installed in the field.
Important! The Fan must be installed in the wall before installing the Cone to the
Fan.
Lay the Cone Panels, with the flanges up, on a flat surface, as shown inFigure 7.
Important! Do not tighten the hardware.
Loosely, fasten the Side Panels together with (3) 5/16-18 x 5/8'' carriage bolts,
(3) 3/8'' lock washers, and (3) 5/16''-18 hex nuts per joint. Only install hardware at
the locations shown in Figure 7.
Set the Cone Side Panels up and align the ends to create the cone shaped housing.
Loosely, secure the ends similar to the other joints.
Note: The flanges should be on the outside of the Cone. Secure each Cone Hanger
Bracket to the Fan Shroud, using 5/16''-18 carriage bolts,
3/8'' lock washers, and 5/16''-18 hex nuts. See Figure 8.

1. Remove Cover Plate Item 1.
2. Install an electrical disconnect within reach of each fan installed.
3. Remove the electrical knock-out nearest the fan power supply outlet.
4. Install the romex connector and cord throughout the knock-out selected before
wiring the motor.

Maintenance 48'' Belt Drive Cone Fan
20 MV1600B
Danger! Disconnect Power Prior To Maintaining Or Cleaning The Fan. The fan
may start automatically causing serious injury or death.
•Service and repair of fans should be done only by a qualified technician.
•Keep the fan clean for maximum life and best performance. Do not spray
water on Fan Shaft Bearings.
•Periodically check the V-Belt. If necessary, adjust the spring tension to prevent
the belt from slipping.
•Keep Shutters, Blades, and Housing clear of obstacles for best air performance.
The Motor and Fan Shaft Bearings are prelubricated. Grease Zerks are provided on
the Fan Shaft Bearings for installations where relubrication is needed.
Important! Relubrication is required once Annually or immediately after cleaning
with a pressure washer. For lubricants, add only a small amount of
grease to purge impurities out of the bearing seals.
DO NOT OVER GREASE!!
Use only high quality lithium soap base grease and clean all dirt from Zerk before
applying grease. (The recommended Grease to use is Shell Avian Grease.)
