Storage
If the fan is stored for any length of time prior to installa-
tion, completely fill the bearings with grease or moisture-
inhibiting oil. Refer to Lubricants on page 6. Also, store the
fan in its original crate and protect it from dust, debris and
the weather.
To maintain good working condition of a SQN when it is
stored outdoors, or on a construction site, follow the addi-
tional steps below:
• Cover the inlet and outlet, and belt tunnel opening to
prevent the accumulation of dirt and moisture in the
housing.
• Periodically rotate the wheel and operate dampers (if
supplied) to keep a coating of grease on all internal
bearing parts.
• Periodically inspect the unit to prevent damaging condi-
tions.
