Frequently Asked Questions
What is the function of Adaptive Energy Optimizing (AEO) mode?
The compressor speed will adapt automatically to the actual cooling demand to optimize performance and consumption.
What conditions trigger a Thermal cut-out error?
This error occurs if the refrigeration system is too heavily loaded, or if the ambient temperature during testing is high.
How must I size the necessary electrical protection components?
The battery protection requires an automobile fuse (12V: 30A | 24V: 15A), and a main switch of at least 30 Amps.
What type and amount of oil should be used for maintenance?
The unit requires polyolester oil, with a standardized quantity of 150 cm.
