冷水机冷冻机操作指南
Operation Manual of Chiller
1.开机前的准备
1. Preparations before start-up
(1).检查机组周围有否异物。
(1) Check whether the unit is surrounded by any foreign substance.
(2).检查机组电源连接是否妥当，(相电源是否符合冷水机电压要求)。
(2) Check whether the power supply of the unit is properly connected (if the phase power supply meets the requirements of chiller voltage) or not.
(3).检查冷却水和冷冻水系统所有阀门是否已开，水塔是否在备用状态。
(3) Check whether all valves of the cooling water system and refrigerated water system have been opened already and if the water tower is in stand-by state or not.
(4).先开系统中的水泵、水塔、后开冷水机。
(4) Firstly open the water pump and water tower in the system and then start the chiller.
※ 必须确定机组及管路系统内水已完全充满，切勿在没水时运行水泵及机组。
※ Make sure that the unit and pipeline system are fully filled with water. Do not operate the water pump and the unit without water.
2. 冷水机操作
2. Operation of chiller
(1).若电源及水喉接驳妥后，首先开启水泵、水塔开关，要留意水泵运转方向，确保水泵按正确方向运转，如方向相反，将电源线 R及 S对调接驳即可，然后开启压缩机开关，再把出水温度设定至所需之温度【通常温度调节不能低于3℃，以防止蒸发器结冰】，机组压缩机运行按容量调节段数自动逐级加载，当系统水温降至所设定温度时，压缩机按容量调节段数自动逐级卸载运行。
(1) If power supply is well connected with the hose, please turn on the water pump and water tower firstly, and pay attention to operation direction of the water pump, so as to ensure that the water pump can operate towards correct direction. If the water pump operates in opposite direction, exchange R end and S end of power supply and then turn on the switch of compressor. After that, set the water temperature as required [normally not lower than 3℃, so as to avoid freezing of compressor]. The compressor should be loaded step by step as per stages of capacity regulation. When water temperature of the system drops to preset temperature, the compressor will be unloaded step by step as per stages of capacity regulation.
(2).关机时先关主机，压缩机停止运转，再关水泵、水塔，最后切断总电源。
(2) Turn off the host machine firstly. After that, close the water pump and water tower after the shutdown of compressor. At last, cut off main power supply.
冷水机操作顺序
Operating sequence of chiller
开机：按“START”键启动机组
Start-up: Press key “START” to start the unit.
开冷冻泵---延时---开冷却泵---延时---根据能量调节开压缩机
Start refrigeration pump---delay---start cooling pump---delay---start compressor as per energy regulation
关机：按“STOP”键停止机组
Shut-down: Press key “STOP” to shut down the unit.
关所有压缩机---延时---关冷却泵---延时---关冷冻泵
Turn off all compressors---delay---turn off cooling pump---delay---turn off refrigeration pump
※ 具体操作内容参照附页《操作面板控制器使用说明》
※ Refer to Operation Manual for Controller of Operation Panel on the attached page for specific operations.
警告：机组参数出厂时已设定，请勿自行调整，否则因此引起的后果将不在保修范围内。
Warning: Parameters of the unit have been set in the factory. Do not adjust the parameters without authorization, otherwise, damages caused hereof shall not be included in the warranty scope.
