2. Safety Alert Decals
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
DC-969
CAUTION
GSI Group, Inc. 217-226-4421
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal pressure from fans
or other air moving systems. Adequate ventilation and/or “makeup air” devices should be provided for all powered
air handling systems. The manufacturer does not recommend the use of downward flow systems (suction).
Severe roof damage can result from any blockage of air passages. Running fans during high humidity/cold
weather conditions can cause air exhaust or intake ports to freeze.
The GSI Group recommends contacting the local power company and having a representative surve y the
installation so the wiring is compatible with their system and adequate power is supplied to the unit.
All precautions should be taken when lifting and/or moving. Use at least two men when moving the
unit anywhere.
The safety pages that follow are to show you where you can find the safety decals. Th e photographs show
exactly where the decals should be.

A = 32" for fans without heaters
A = 55" for fans without heaters
TR-4734
A = 21"
TR-7048
A = 45" for fans without heaters
A = 68" for fans with heaters
Fan Pad Location
Fan pad should be poured level with top of bin foundation for all Inline Fans 18" through 28" diameter. Fan
should be centered on center line of bin. Front of pad should be perpendicular to bin wall. Recommended
thickness for fan pad is 4" minimum.
IMPORTANT: Fan pad and fan must be level and smooth for proper operation. Vibration problems can
result from improper fan leveling.
Check List before Installing the Fan
1. One of the most important factors for installation is providing adequate power to run the unit.
Undersized wire can lead to voltage drop and can cause motor overheating and shortened life.
Therefore, it is necessary to know the distance from the unit to available transformer and the
horsepower of the fan unit. These two (2) factors will determine the size of wire ne eded for ef ficient
operation. See fan specifications on Page 11.
2. It is recommended to contact the local power company and having a representative survey the
installation so the wiring is compatible with their system and adequate power is supplied to
the unit.
3. Each fan motor should be wired through a fused or circuit breaker disconnect switch.
4. Refer to fan specifications on Page 11 for the recommended slow blow fuse or breaker size to use
when installing the particular fan.
5. Standard electrical safety practices and codes should be used. (Refer to National Electrical Code
Standard Handbook by National Fire Protection Association.)
6. A qualified electrician should make all electrical wiring installations.
