A: You should confirm the target cooling capacity, evaporating and condensing temperatures, selected refrigerant, supply voltage/frequency, and whether an economizer circuit or liquid injection is required.
A: Pre-heat the crankcase via the electrical heater before startup to prevent liquid refrigerant accumulation, verify proper initial oil charge level through the sight glass, and check rotation direction during momentary power-on.
A: The INT69 SNY module continuously measures temperature signals from six built-in PTC thermistors and automatically opens the safety circuit to trip the compressor if thermal thresholds are exceeded.
A: Regularly inspect the oil clarity, check the differential pressure across suction line strainers and oil filters, and verify clean electrical connections on the terminal box and protection module.
