Fan and Fan Framing Dimensions

Planning the layout of the spacing between fans is very important. A Minimum of 13" between Fan rough openings
is required so the Cones do not interfere. Dimensions for rough openings for Fans are shown in Figure 2 below.

Important! The Fan Inlet and exhaust must be kept clear of obstructions. Failure to keep the Fan airflow path clear
of obstructions could cause loss of Fan perfomance and Fan damage.

Do Not operate these Fans with a variable speed control device. Operating static pressure should be less than 0.15
inches water column.

Step 1: Set the Fan in the Framed

Opening. Rotate Fan Blade and
Check for 1/8" Blade Tip
Clearance

Note: Fan shown without components for clarity.

Fan Mounting

Insert the Fan Assembly in the wall opening. Rotate the Fan Blade by hand and check to make sure that
there is a minimum of 1/8" Blade clearance all the way around the Shroud orifice. Shift the Fan around in
the wall opening, if needed, to achieve at least 1/8" clearance all the way around. Now the Fan is ready to
be attached to the wall.

included in the Parts Package (Item 1, Figure 3) with these three holes, slip them over the top Fan Shroud
flange, and using (3) 1/4 x 1-3/4 Lag Screws included in the Parts Package attach the Fan to the Wall
(Step 1, Figure 3). In each of the remaining 5 holes in the Fan Shroud flange, use a 1/4 x 1-3/4 Lag Screw,
two Nylon Washers, and a Screen Clip, all included in the Parts Package, to secure Fan to the Wall as
shown below in Step 2. Only tighten the Lag Screws enough that the Clip will retain it’s position, but can
still be rotated by hand. Use two more Lag Screws to attach the Fan to the Wall through the holes in the
Post Brackets (Step 3, Item 6).

Removing the Doors

To avoid damaging the Fan Doors it is best to remove them before attaching the Cone. Unhook the Door Springs from the Door
and leave them attached to the Fan so they are not lost (Figure 4, Step 1). Remove the Door Clip and Washer and open up the
Doors (Step 2). You can discard the Door Clip and Washer. Lift one Door up so it will clear the Bottom Pivot Bracket (Step

3), and Pull the Door out (Step 4). Set the Door aside. Repeat the same process to remove the second Door.

Attaching the Cone

To install the Cone you must first identify the Top of the Cone. The cutout in the top of the Cone does not extend
out to the Cones edge (See Figure 5). Begin Installing the Cone by hooking the top of the Cone over the top of the
Fan orifice. At this time only attach the Cone to the Shroud at the upper most two holes using (2) 1/4-20 Bolts and
(2) 1/4-20 Flange Nuts provided in the Parts Package (See Figure 5).

Slide the Remaining Cone over the Shroud orifice, working around the Cone from top to bottom. When you get to
the bottom of the Cone it is best to have a second person push down on the Cone from inside the Fan as you push
the Cone on. (See Figure 6 below).

Replacing the Doors

Replace the Doors by reversing the steps used to remove them in the Removing the Doors section of this manual.
Important: Re-attach the Door Springs to the 1st Hole in the Doors (Figure 8). In windy conditions: If the Fan

Doors do not close when the Fan is off, or if the Doors open before the Fan turns on; increase the Spring tension by
re-attaching the Spring to the second or third hole in the Doors.

1. See Wiring diagram on Motor for Motor electrical connections. Follow local, state, and national electrical codes
for wiring

2. Install an electrical disconnect within reach of each Fan.

3. Route the motor cord (not supplied) toward the upper left corner of the Fan and attach the cord to the Motor Mount
using the Cable Tie—included in the hardware package. Leave a Drip Loop so that moisture collecting on the
Cord will not run down and damage the Motor (See Figure 12). Cut out a section of the Screen where you want
the Cord to exit the Fan, so that the Screen can be removed without the Cord getting in the way Figure 12). Use
the Nylon Cord Retainer and Lag Screw provided to secure the Cord to the Wall outside of the Fan. (Figure 12)

Maintenance

•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, Belt

Tensioner, or the Motor.

• Periodically check the V-Belt and replace if necessary. A bad Belt will cause a substantial drop in Fan perfor­mance or can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the Belt. (See Figure 13)

• Keep HYFLO® Doors, Blades, and Housing clear of obstacles for best air performance.




•Check Sheaves for wear. Replace if Sheave

groove is worn.

(See Figure 13 to the Right).

Fan Bearing and Belt Tensioner
Lubrication

• Grease zerks are provided for lubrication on the fan shaft bearings and the belt tensioner.

• Lubricate the fan every 2-6 months or whenever these components get wet.

• Disconnect power to the fan before lubricating.

• Clean the zerk before lubricating to prevent contamination from entering the bearing.

• Use a high quality lithium based, NLGI #2, grease such as Shell Gadus S2 V100 2. Do not use incompatible greases
containing aluminum, barium, calcium, bentonite clay or polyurea thickeners.

• Slowly rotate the fan shaft by hand while slowly applying the grease. Rapidly applying grease to a stationary bearing
can damage the bearing seals.

• Apply about .10 oz (2.8 g, 3.1 cc) of grease at a time or until a slight amount of grease can be seen purging from the
seal.
