The compressor is tripped by the high pressure switch protection, the compressor stops running, the heat dissipation is poor, the high pressure is overloaded and the fault code or fault indication is displayed. At this time, please check whether the circulating water of the cooling tower is normal, whether the temperature of the cooling water is too high, whether the fan pump of the cooling tower is running, Check whether the cooling water compartment is fully open (for air-cooled models, please check whether the radiator is dirty or blocked), press the reset button (REST) after the above is normal, or shut down and restart to operate normally. If high pressure overload occurs frequently, please arrange to clean the condenser as soon as possible
