S ERVICE AND MAINTENANCE
Any service procedure not described here should be referred to a
qualified technician.
Warning! Disconnect the fan from power before removing any grills or
covers.
C l e a n i n g
Clean the outside of the fan with a damp cloth only. Do not use solvents.
Periodic cleaning of the fan blades and grills is necessary to maintain
peak performance. Cleaning intervals will depend on the operating
environment. Inspect the fan regularly for dust and smoke residue
buildup, and clean as soon as there is significant dirt buildup on fan
blades or at the first signs that airflow through grills may be restricted.
Use a soft brush and vacuum to clean grills and fan blades.
