Step 3
Installing the one piece cone may require 2 people. If temperature is above 50°F then proceed to Step 5.
If temperature is below 50°F then proceed to Step 4.
Step 5
Look for the “TOP” label on the Polycone and set the top of the Polycone on top of the fan orifice
and install (2) Truss Head Bolts [B] through holes in fan outlet through the slots in the cone at about
the 10 and 2 o’clock positions and fasten with Washers [C] and Flange Nuts [D]. Truss head of
each bolt must be on the inside of the fan outlet; washers and flange nuts must be on outside of cone.
See Figure 5A and 5B. Finger tighten nuts only at this time.

Step 6
Work down the sides of the cone, sliding the cone tabs onto the fan until the bottom tab is in place. Keep
pressure on the cone to make sure tabs stay on the fan. Install (6) Truss Head Bolts [B], Washers [C] and
Flange Nuts [D] in the remaining holes in the fan outlet and slots in the cone to finish securing cone to fan.
See Figure 5B and Figure 6. Tighten all nuts at this time, making sure not to over tighten.

Step 7
The snap-in guard has a slight conical shape to it so, when installed the center of the guard should protrude
out slightly. See Figure 7A.
51/55 RC Cone Guard

Step 9
If installing your existing guard into the new cone, locate the flat guard mounting pads on the cone and drill
a 9⁄32” dia. hole in the center of each pad. Then insert existing guard into cone with the guard eyelets facing
away from you. Line up each eyelet with a hole in the guard pads. Secure guard to cone using (8) existing
Bolts and Nuts. See Figure 8A and 8B. Tighten all nuts at this time.
Step 8
Starting at the bottom of the cone, locate one of the guard tabs and put the guard tab through the guard slot
in the cone. See Figure 7B. Then work up around the guard and install each of the other guard tabs in each
of the corresponding guard slots. Some force may be required to snap the last tab into the last slot, pull out
on the center of the cone while pushing in on the guard tab until it snaps into place.
