Fan Coil Maintenance
Room fan-coil units are equipped with either filters that should
be cleaned or replaced when dirty. Good filter maintenance improves
sanitation and provides full airflow, ensuring full capacity.
The frequency of cleaning varies with the application. Units in
apartments, hotels, and hospitals usually require more frequent
filter service because of lint.
Fan-coil unit motors require periodic lubrication. Motor failures
are not common, but when they occur, the entire fan can be quickly
replaced with minimal interruption in the conditioned space. The
condensate drain pan and drain system should be cleaned or flushed
periodically to prevent overflow and microbial buildup. Drain
pans should be trapped to prevent any gaseous backup.
