Chapter 1: Safety Precautions
Lifting Hazard
• Single person lift can cause injury.
• Use a mechanical lifting device to lift or move the equipment
during installation.
ST-0021–2
Explosion Hazard
• The fan is not designed for use in atmospheres where the
risk of explosion is present.
• Do not use the fan in enclosed areas of high dust concentra-
tions, flammable gas, vapors or fumes.
ST-0022–1
Keep Hands Away from Moving Parts
• Do not operate the fan with electrical or mechanical guards
removed. Serious injury or death can result.
• Do not put hand or arm in fan. Rotating parts can crush and
dismember.
• Do not put any kind of tool inside the fan to clear debris
while the fan is operating. Damage to the equipment will
result.
• Lock-out power source before making adjustments, clean-
ing, or maintaining equipment.
ST-0020–2
Install and Operate Equipment Properly
• The fan described in this manual is designed solely for the
purpose of ventilating agricultural buildings. Use of the fan in
any other way is a misuse of the equipment and may endan-
ger health and safety.

Chapter 1: Safety Precautions
Install and Operate Fan Properly
• Electrical controls and wiring must be installed by a qualified
electrician and must meet the standards set by the National
Electric Code, Canadian Electrical Code, and all local and
state codes. The fan must be installed and maintained by a
qualified person familiar with the use and function of ventila-
tion fans.
• Lock-out power source before making adjustments, cleaning,
or maintaining equipment.
• Do not operate fan unless the motor is properly grounded.
Grounding can be achieved by wiring with a grounded con-
duit or a separate ground wire attached to the motor ground
lug.
• Do not operate the fan by bypassing any safety device on
the unit.
• Do not kink power cables and do not allow cables to come
into contact with oil, grease, hot surfaces or chemicals.
• Motor overload protection must be provided with each single
phase fan. A circuit breaker or slow blow motor type fuse
must be used. A safety cut-off switch must be located adja-
cent to each fan.
• Fans used to ventilate livestock buildings and other rooms
where continuous air movement is essential must be con-
nected to individual electrical circuits with a minimum of two
(2) circuits per room.
• Installation of supplementary natural ventilation, back-up
thermostat and an alarm system on at least one cooling
stage is recommended. See diagram on motor nameplate
and information provided with fan control (if used) for con-
nection requirements.
ST-0018–2
Sharp Edge Hazard
• This product has sharp edges, which can cause serious
injury.
• To avoid injury, handle sharp edges with caution and always
use proper protective clothing and equipment.

Chapter 1: Safety Precautions
Maintain Equipment and Work Area
• Do not attempt maintenance or repairs on the fan unless you
are competent to do so. Understand service procedures
before doing work.
• Use only genuine Cumberland parts when maintaining the
fan. Use of other non-genuine parts is a misuse and can
lead to dangerous situations.
• Be aware that the fan may operate under automatic control
and may start without warning.
• Lock-out power source before making adjustments, cleaning,
or maintaining equipment.
• Keep area clean and dry.
• Keep hands, feet, and clothing away from moving parts.
• Keep the fan in proper working condition. Replace worn or
broken parts immediately.
• Keep the fan clean. Do not allow debris to collect around
motors, belts, pulleys or bearings.
• Make sure that all electrical enclosures and guards are
closed and locked before re-starting the fan.

General Description
The structure of the butterfly shutter on the Mega Flow Butterfly Fan improves fan stability and eliminates
small blades that are prone to dust and build-up that reduce air flow. The butterfly shutter also provides
protection against harsh weather conditions such as wind and moisture while the fan is not in use.
During operation, the air forces the shutter doors to open. A magnetic shutter panel ring is used to stop
the shutters from moving when the fan is off.
The Mega Flow Butterfly Fan is belt driven and has a spring loaded belt tensioner to ensure proper belt
tension.

Chapter 3: Assembly
Framing and Positioning
Before You Begin
Make sure that you have enough rough opening and there is enough space so that the fan flanges do not
overlap.
1. Construct the frame opening to 61-1/4 in. H x 58 in. W.
NOTE: Remember that the framing must be able to support the weight of the fan assembly. Ensure
the load bearing portion of the bottom sill is rigid and properly supported.
2. Plan the layout and spacing of fans with cones; spacing fans too close together will cause
interference with the cones.
Figure 3-1 54 in. Framed rough opening
NOTE: 3/4 in. has been added for fan clearance.

Figure 3-2 Center to center fan spacing with cone
IMPORTANT: The cone diameter is normally 74 in. diameter but the “Arches” in the side cone
panels can be flattened giving a total of 64 in. side to side. See tabbed cone panel
assembly for details. If not sure of sufficient clearance, contact your local
distributor for more information.
