    Note: Follow local codes and standards when designing duct runs to deliver the required airflow. Minimize noise and excessive pressure drops caused by duct aspect ratio changes, bends, dampers and outlet grilles in duct runs. ICE CFA3240A-3300A-3360A I&O Manual 10/2023 Rev.11...
  • Page 7: General Operation

    Cold liquid refrigerant passing through the evaporator is boiled into gas by heat removed from the air. The warmed refrigerant gas enters the compressor where its temperature and pressure are increased. The hot refrigerant gas condenses to liquid as heat is transferred to outdoor air ICE CFA3240A-3300A-3360A I&O Manual 10/2023 Rev.11...
