Cleaning
Clean the outside of the fan with a damp cloth only. Do not use
solvents. Periodic cleaning of the fan blades and grilles is
necessary to maintain peak performance. Cleaning frequency
depends on the operating environment. Inspect the fan regularly
for dust and smoke residue buildup. Clean as soon as there is
significant dirt buildup on fan blades or if airflow through grilles
becomes restricted. Use a soft brush and vacuum to clean grilles
and fan blades.
