Check before starting upWater circuit partCheck all the pipelines of the water system to ensure that the evaporator and the condenser are correctly connected and the water flow direction is correct. Check if the inlet pipe and the outlet pipe of the heat exchanger mentioned above are well connected, and then open all the water valves and start up the corresponded water pump to wash the pipes so as to ensure the water system is clean and check if there is any leakage at the pipes and joints. Discharge the air in the water circuit of the evaporator and the condenser, and the water circuit should be keep clean away from rust. Check the resistance loss at the water side of the evaporator and the condenseragainst the water volume. Check if the temperature transducers are correctly connected. Electric circuit partCut off the main isolating switch and then check all the startup circuits and control circuits of the control cabinet to ensure all the switches are in off position. Check the power supply to the chiller and the voltage fluctuation range should be within 10% of the±rated voltage shown on the nameplate of the compressor, and the unbalance of the phase voltage should be within 2%. Check if there is enough power supply capacity to ensure the startup andfull load running of the chiller. Check if all the electric wires and fuses have the matched specification with the running of the chiller, and finish all the interlock control circuits according to the related electric control drawing. Check and ensure all the ancillary equipments and control equipments for air-conditioning are in normal operation and have enoughrefrigerating capacity to satisfy the running requirement of the chiller at the first operation. Chiller partMake sure that the engine oil heater of the compressor has been electrified for 24 hours, and examine the oil level through the inspecting mirror of the oil separator,and refill oil if the oil level can not be seen. Fully open the manual stop valve on the sparging pipe and remove the seal bonnet away, and fully open the suction and discharge stop valve and then counterclockwise turn it back for 1/2 circle, and then fully open the liquid supply stop valve and start up the ancillary equipments, the condensed water pump and the refrigerated water pump, and finally check if all the safety control equipments are in original status and if thesettings are correct. See <Table 1> below for the related items for checking.Safety equipmentsThe chiller is equipped with safety protective devices to ensure safe running, and if one of the safety protective devices is in operation, an error indicator will turn on, and the corresponded function will stop while the other functions will be still normal.
