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.

Remove the Fan from the Crate and Install into Wall opening. The Danger Decals should be located at the
bottom of the Fan as shown below. In the holes at the side center locations Use 1 Lag Screw, 2 Nylon
Washers, and 1 Screen Clip to attach the Fan to the wall (See Figure 2). These Screen Clips will later be
used to hold the Screen on. Install Lag Screws in the remaining 6 locations as shown inFigure 2.
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 3). 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.
Belt Installation
Guide the Belt through the Opening in the Motor Support Bracket and loop it over the Motor Sheave. Guide
the Belt around the Tensioner Sheave and push on it to get enough slack to put the Belt on the Driven Sheave
as shown in Figure 4. Make sure the Belt does not rub against the Motor Support Bracket.

48" and 52" HyfloTM Fans Installation and Operators Instruction Manual Cone Assembly
MV1747D 3
The Cone Panels can be identified by the number of notches at the edge of each Panel. Begin the Cone
assembly by laying the Panel withno tabs on a couple of boards with the one notch end to the left and with
the Knock-out at the Bottomas shown in Figure 6. Insert the tabs into the slots on the edge with the same
number of notches.
When all four Cone Panels are connected stand the panels up on edge and curl the Cone around with the
smaller diameter of the Cone up as shown below. Assemble the final Panels together and allow the Cone to
take its shape. If the Cone is assembled correctly the Tabs should all be on the Inside of the finished Cone.
Fasten the Cone Panels together with (4) 5/16 x 1/2" Hex Bolts Threaded in from the inside of the finished
Cone as shown in Figure 7.

Door Assembly/Installation 48" and 52" HyfloTM Fans Installation and Operators Instruction Manual

To install the Door in the Cone you must first identify the top of the Cone and the top of the Door. The
bottom of the Cone Has a C-shaped cut-out in it that will later be used for a drainage knockout(See Figure
8). The top of the Door can be identified by the location of the Door Springs. The Spring attaches to the Post
towards the top of the Door(See Figure 8). With the Door opening towards the ground, as shown below,
line up the Four Holes in the Door Ring with the second set of holes from the edge of the Cone and thread
(4) 5/16 x 1.25" Bolts in until they are tight. Do not install Nuts at this time. These Bolts will be used later
to attach the Cone Brackets.
Use (2) 5/16 x 1.25" Boltsand 5/16 Flange Nuts to attach the Ring to the Cone using the Holes located on
both sides near the Door Center Brace as shown below. Note that the Nuts go on the outside of the Cone.
Turn the Cone over to install the Grill. Orient the Grill so the Leg with the bent spokes at the Center of the
Grill is Parallel with the Center Door Hinge and that the bent Spokes are either above or below center. Not
to the left or right. (SeeFigure10). Install the Rubber Grommet 3/4" to 1" from the end of the bent Spokes.
Fasten the Grill on with (8) 5/16 x 1/2" Carriage Bolts and Flange Nutsas shown below. Note that the Nuts
are to the Inside of the Cone.

MV1747D 5
Use 5/16 x 1/2" Carriage Bolts and 5/16 Flange Nuts to attach the Cone Brackets to the Fan Shroud as
shown. The Shorter Cone Brackets go on the top. The Longer Cone Brackets go on the bottom as shown in
Figure 11.
Mounting the Cone and Door Assembly on the Fan requires at least two people. Pick up the Cone and rest
the Cone on top of the Fan Orificeas shown in Figure 12A. Attach the top of the Cone to the Cone Brackets
with the Bolts that were previously threaded through the Ring and Cone and 5/16 Flange Nuts(Figure 12A).
Only hand tighten the Nuts at this time. Working around the Fan Orifice in a circular motion Slide the Cone
over the Fan Orifice. The Cone will Fit snug over the Fan Orifice. 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 (Figure 12B). Use
a Level and rotate the Cone until the Door center rail is Vertical. Now tighten all Hardware (See Figure
12C).

Wiring 48" and 52" HyfloTM Fans Installation and Operators Instruction Manual
6MV1747D
1.Check that the electrical power being supplied to the Fan matches the electrical Specifications on the Fan
Decal.
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.)
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 13). 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.
Hang the Rear Screen on the four tabs located in the corners of the Fan Mounting Flange. Position the Screen
so that the Screen wire is captured between the 1/8" tall tabs and the Screen Clips. Rotate the two Screen
Clips to capture the Screen (See Figure 14).

48" and 52" HyfloTM Fans Installation and Operators Instruction Manual Maintenance
MV1747D 7
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.
•Keep the fan clean for maximum life and best performance. Do Not spray water on Fan Shaft Bearings
or Motor.
•Periodically check the V-Belt and replace if necessary. A worn Belt will cause a substantial drop in Fan
performance or it can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the belt.
(See Figure 15 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 Ten-
sioner Housing (See Figure 16).
•Keep Shutters, Blades, and Housing clear of obstacles for best air performance.
•The motor and Fan Shaft Bearings are pre-lubricated.Grease zerks are provided on the fan shaft bearings
for installations where re-lubrication is needed. Add only a small amount of grease to purge impurities
out of the bearing seals. Use onlyhigh quality lithium soap base grease and clean all dirt from zerk before
applying grease. Chore-Time recommends using Shell Alvania # 2 in the fan shaft bearings.
Check Sheaves for wear. Replace if a Sheave groove is worn. (See Figure 17)
