Lennox TSA (6, 7.5, 10, 12.5, 15 & 20 Tons): Maintenance

    Installation and service must be performed by a licensed professional installer (or equivalent) or a service agency. At the beginning of each cooling season, the system should be checked as follows:

    Outdoor Unit

    NOTE ‐ If insufficient cooling occurs, the unit should be gauged and refrigerant charge should be checked.

    Outdoor Coil

    Clean and inspect outdoor coil (may be flushed with a water hose). Ensure power is off before cleaning.

    NOTE — It may be necessary to flush the outdoor coil more frequently if it is exposed to substances which are corrosive or which block airflow across the coil (e.g., pet urine, cottonwood seeds, fertilizers, fluids that may contain high levels of corrosive chemicals such as salts)

    Sea Coast — Moist air in ocean locations can carry salt, which is corrosive to most metal. Units that are located near the ocean require frequent inspections and maintenance. These inspections will determine the necessary need to wash the unit including the outdoor coil. Consult your installing contractor for proper intervals/procedures for your geographic area or service contract.
