Before each heating season,
remove front panel and inspect
coil fins for accumulation of dust
or other debris that may block
airflow between fins. Brush the
entire finned surface with a soft
bristled brush, brushing parallel
to the fins, taking care not to
damage the fins. Brushing should
be followed by cleaning with a
vacuum cleaner. Compressed
air can also be used by blowing
air through the coil fins, again
followed by vacuuming. If fins
are damaged during the cleaning
process, use an instrument
screwdriver or other small, flat-
edged tool to restraighten fins.
