Figure 2. Fan Spacing
Planning the layout of the spacing between Fans is very
important. Spacing too close together will cause interference
between the discharge Cones. The Rough Opening
dimensions for Fans are shown above.

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

Assembly for 9" Panel Models (models 49515-XX and 49519-XX)
Hyflo® Fans with 9" panels need to be repositioned from their shipping position before they can be installed.
Remove the Fan from the Crate, and with the Blade down, rest the Fan Shroud orifice on sawhorses. Do Not
rest the Fan on the blade. (See Figure 3 below)
Remove the 1/4 x 1/2" Screws from the Side Panels (Figure 4). Shift the Panels up until the second set of
holes in the Panels line up with the holes in the Shroud (Figure 5). Re-attach the Panels with the 1/4 x 1/2"
Screws as shown. Repeat the same procedure for the Top and Bottom Panels. The additional 1/4 x 1/2"
Screws that are required are included in the Parts Package. Once all of the Panels have been shifted attach
the Panels at the corners with 1/4 x 1/2" Screws.

Attaching the Fan to the Wall
Slide the Fan assembly into the rough opening and starting with the two side hole locations (Detail A), use
1/4 x 1-3/4" Lag Screws (Item 1, Figure 8), two Nylon Washers (Item 2), and a Screen Retainer (Item 3)
to attach the Fan to the Wall as shown. Use 1/4 x 1-3/4" Lag Screws to attach the Fan at the four corners
(Detail B), and at center Top and Bottom (Detail C) as shown.
Securing Screen Clips on 52" Fans only
For 52" Fan applications, the Screen Clips (Item 4) on the Top Panel need to be secured in place by installing
a Lag Screw through the holes in the Panel and into the Framing as shown in Detail "D".
Motor Installation
Rotate the Motor Support Bracket into the upright position by removing the Upper Carriage Bolt and Nut
and loosening the Lower Bolt and Nut (See Figure 9). Rotate the Motor Support Bracket until it is
perpendicular to the Fan Posts and fasten with (4) 5/16 Carriage Bolts and (4) 5/16 Flange Nuts. Note that
the Nuts go outside the Posts. Remove the Motor from the Crate and attach it to the Motor Support Bracket
with (4) 5/16 Carriage Bolts and (4) 5/16 Flange Nuts as shown.

Do not tighten down the Nuts at this time. Leave the
Nuts loose until the Cone is attached to the Fan.
Step 4: Stand the Panels up on edge and curl the Panels
around making a Cone shape with the smaller
diameter up. Insert the Tabs of the last Panel into
the Slots of the 1st and allow the Cone to take its

Step 2: Insert the Tabs of the second Cone Panel into the
slots of the 1st Panel and lay it down locking the
two Panels together.
Step 3: Repeat Step 2 until all four Cone Panels are
locked together.

Installing Fans 60"-64-1/2" on Center
If 52" Fans need to be installed 60"-64-1/2" on center, Cone Clips can be used to keep Cones from interfering with
one another. First, cut the two legs from the horizontal Screen wire as shown in Figure 16 below.
Holding a Cone Clip in place, Push in the side of the Cone and fasten with 5/16 x 1/2" Carriage Bolts and Flange
Nuts as shown in Figure 17 below.

Assembling the Cone to the Fan
Use 5/16 x 5/8" Carriage Bolts and 5/16 Flange Nuts to attach the four Cone Brackets to the Fan Shroud as shown
in Figure 18.
Mounting the Cone and Door Assembly on the Fan requires at least two people. Pick up and orient the Cone with
the Door Stop Cable (Item 1, Figure 19) attached at the top and rest the Cone on top of the Fan Orifice as shown.
Attach the top of the Cone to the Cone Brackets (Item 2) with the Bolts that were previously threaded through the
Ring and Cone and secure with 5/16 Flange Nuts (Item 3). Only hand tighten the Nuts at this time. Working around
the Fan Orifice from inside the fan, in a circular motion Slide the Cone over the Fan Orifice. The Cone will Fit snug.
Use the Bolts previously threaded through the Ring and Cone and the 5/16 Flange Nuts to secure the bottom of the
Cone to the Fan as shown. Use a Level and rotate the Cone until the Door center rail is Vertical (See Figure). Now
tighten all Hardware.

Wiring
1. Check that the electrical power being supplied to the Fan matches the electrical Specifications on the Fan and
Motor Decals.
2. Remove the Motor Access Cover.
3. Install an electrical disconnect within reach of each Fan installed.
4. Connect the cord to the motor according to the wiring diagram on the motor. Verify that the motor is connected
for counter clockwise rotation (viewing the back of the motor, opposite the shaft end.)
5. Follow local, state, and national electrical codes for wiring. Cut out one section of the Screen to route the cord
out of the Fan: This will allow for the Screen to be removed without interfering with the Cord. (See Figure 23).
Attach the cord to the Wall using a Lag Screw and Cord Clip. Allow enough slack in the cord to form a "drip
loop" for moisture to fall away from the cord and not into the motor
NOTE: For variable frequency drive wiring, see instruction located in the 52"
Hyflo frequency drive kit (part no. 51738).

MV1832P 17
IMPORTANT! 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.
•Minimize contact of moisture or corrosive chemicals to the surfaces of the fan components to maximize fan life.
•After washing fans, operate fans long enough to remove moisture from all fan surfaces.
• Keep the fan clean for maximum life and best performance. Do Not spray water on the Fan Shaft Bearings, the
Belt Tensioner, or the Motor.
• Periodically check the V-Belt and replace if necessary. A worn Belt will cause a substantial drop in Fan perfor-
mance or it can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the belt. (See Figure
25 below)
• Check Belt Tension. The Belt should be
tensioned just tight enough to minimize
Belt slippage. Over tensioning the belt
will cause premature Belt and Bearing
wear. With a new Belt the Idler Sheave
indicator mark should line up with the
third notch in the Tensioner Housing (See
Figure 26).
• Keep Shutters, Blades, and Housing clear
of obstacles for best air performance.
•Check Sheaves for wear. Replace if a Sheave groove is worn. (See Figure 27)

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.
