Hi , "Please inform me where in the official Daikin information I can find the following description, especially regarding the overhaul recommendations. Thank you. "For Daikin LXE10E-A series reefer units, it is generally recommended to perform a major overhaul every 40,000 running hours. Additionally, a minor overhaul should be conducted every 20,000 running hours. These intervals help ensure optimal performance and prevent unexpected breakdowns."
