Maintenance
Coil Fins and External Surface Cleaning
Coil should be kept clean to maintain maximum performance. For operation at its
highest efficiency, the refrigerant coil should be cleaned often during periods of high
cooling demand or when dirty conditions prevail. A routine cleaning schedule
(minimum of once per year) is recommended to prevent dirt buildup in the coil fins,
where it may not be visible.
Remove large debris from the coils and straighten fins before cleaning. Remove
filters before cleaning.
Clean refrigerant coil with cold water and detergent, or with one of the commercially
available chemical coil cleaners. Rinse coils thoroughly after cleaning.
