installation, completely fill the bearings with grease or
moisture-inhibiting oil. Refer to Lubricants on page 3. Also,
store the fan in its original crate and protect it from dust,
debris and the weather.
• Cover the inlet and outlet opening to prevent the
accumulation of dirt and moisture in the housing.
• Periodically rotate the wheel to keep a coating of
grease on all internal bearing parts.
• Periodically inspect the unit to prevent damaging
conditions.
