48" and 52" Vanguard Plus Belt Drive Fans Installation and Operators Instruction Manual
Cone Assembly
The Fan Cone is assembled by interlocking four identical Panels (See Figure below).Use a piece of lumber
to prop up the end of a Panel with slots. Interlock two Panels by sliding the tabbed end of another Panel into
these slots. Repeat this process to attach all four Panels. The Panels when assembled should form a
continuous "C" shape as shown. With the Panels interlocked and laying flat on the ground, stand the Panels
up on edge and curl them into a Cone shape with the tabs to the inside of the Cone. Interlock the two
remaining edges to form the complete Cone. Turn 5/16x 1-1/4 Hex Bolts into the four holes near the upper
edge of the Cone. The bolt heads need to be on the inside of the Cone as shown.
Flip the Cone over so that the large end is up, and install the Grill using 5/16 Carriage Bolts and Flange Nuts.
Use 5/16 Carriage Bolts and Flange Nuts to attach the Cone Brackets to the Fan Shroud as shown. Pick up
the Cone and rest it on top of the Fan orifice. Line up the 5/16 Flange Bolt previously threaded into the Cone
with the holes in the Cone Brackets and fasten with 5/16 Flange Nuts. Working around the Fan Orifice in a
circular motion Slide the Cone over the Fan Orifice. The Cone will Fit snug. Use 5/16-18 Flange Nuts to
secure the bottom of the Cone to the Cone Brackets.
