Manual and understand-ing the fans operation.
Pearson has endeavored to design and make
the best ventilation equipment possible. How-

tion only. It is not designed to move/transport
any sort of liquid or semi-liquid material.
Do not operate the fan in any explosive or

plosive or flammable environment.
Keep the unit grounded with athree pronged
grounding plug and agrounded electrical out-
let. Do not use an ungrounded extension cord
