2. Safety Decals
CAUTION!
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
GSI 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. GSI 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 your 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.
Safety decals should be read and understood by all people in the grain handling area. The bottom-right
decal warns that the enclosure contains electrical devices carrying high voltages that will cause inju ry or
death. Lock out power before servicing. If a decal is damaged or is missing, contact:
