Periodic Maintenance
Periodic maintenance is recommended to ensure proper operation of
the unit. Recommended maintenance intervals may vary depending on

Cleaning the Coil
Clean the coil at the beginning of each cooling season, or when
necessary. Use a vacuum cleaner or a long-bristle brush to avoid
damage to the coil fins.
