冷水機冷凍機操作指南
Operation Manual of Chiller

1.開機前的準備
1. Preparations before start-up

(1).檢查機組周圍有否異物。
(1) Check whether the unit is surrounded by any foreign substance.

(2).檢查機組電源連接是否妥當，(相電源是否符合冷水機電壓要求)。
(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).檢查冷卻水和冷凍水系統(tǒng)所有閥門是否已開，水塔是否在備用狀態(tài)。
(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).先開系統(tǒng)中的水泵、水塔、后開冷水機。
(4) Firstly open the water pump and water tower in the system and then start the chiller.

※ 必須確定機組及管路系統(tǒng)內(nèi)水已完全充滿，切勿在沒水時運行水泵及機組。
※ 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. 冷水機操作
2. Operation of chiller

(1).若電源及水喉接駁妥后，首先開啟水泵、水塔開關(guān)，要留意水泵運轉(zhuǎn)方向，確保水泵按正確方向運轉(zhuǎn)，如方向相反，將電源線 R及 S對調(diào)接駁即可，然后開啟壓縮機開關(guān)，再把出水溫度設定至所需之溫度【通常溫度調(diào)節(jié)不能低于3℃，以防止蒸發(fā)器結(jié)冰】，機組壓縮機運行按容量調(diào)節(jié)段數(shù)自動逐級加載，當系統(tǒng)水溫降至所設定溫度時，壓縮機按容量調(diào)節(jié)段數(shù)自動逐級卸載運行。
(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).關(guān)機時先關(guān)主機，壓縮機停止運轉(zhuǎn)，再關(guān)水泵、水塔，最后切斷總電源。
(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.

冷水機操作順序
Operating sequence of chiller

開機：按“START”鍵啟動機組
Start-up: Press key “START” to start the unit.

開冷凍泵---延時---開冷卻泵---延時---根據(jù)能量調(diào)節(jié)開壓縮機
Start refrigeration pump---delay---start cooling pump---delay---start compressor as per energy regulation

關(guān)機：按“STOP”鍵停止機組
Shut-down: Press key “STOP” to shut down the unit.

關(guān)所有壓縮機---延時---關(guān)冷卻泵---延時---關(guān)冷凍泵
Turn off all compressors---delay---turn off cooling pump---delay---turn off refrigeration pump

※ 具體操作內(nèi)容參照附頁《操作面板控制器使用說明》
※ Refer to Operation Manual for Controller of Operation Panel on the attached page for specific operations.

警告：機組參數(shù)出廠時已設定，請勿自行調(diào)整，否則因此引起的后果將不在保修范圍內(nèi)。
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.
