Mobile Box Fan User’s Manual

Note:
The fan unit you have purchased is built with heavy duty components, designed to give you many years of perfor-
mance. Like anything else that is mechanical, your fan unit will require a small amount of periodic maintenance to assure
maximum efficiency.
Our fans utilize motors that have totally sealed bearings. Periodically remove dust and grime that has accumulated on the
motor, fan blade, and guard. Pressure washing the unit will void the warranty. Performing this small amount of mainte-
nance will keep your fan unit running as efficiently as when it was brand new.
