Maintenance Section 418 Part Number 000007651 05/10Cleaning the CondenserAir-Cooled CondenserA dirty condenser restricts airflow, resulting inexcessively high operating temperatures. This reducesice production and shortens component life. Clean thecondenser at least every six months. Follow the stepsbelow.1. The washable aluminum filter on self-contained icemachines is designed to catch dust, dirt, lint andgrease. This helps keep the condenser clean. Cleanthe filter with a mild soap and water solution.2.
