低温冷水机保养注意事项 Maintenance Notices 1、 定期检查冷媒量，运行中指示低压应在3.5 Kg /cm2以上。 Check the cooling medium quantity regularly, the low pressure should be above 3.5 Kg /cm2 when running. 2、 若为半封闭式压缩机，要定期检查油量，正常应在窗口的2/3以上。 If the compressor is semi-closed, check the oil quantity regularly and it should be more than 2/3 of the window normally. 3、 每隔六个月刷洗冷凝管。 Clean the condenser every 6 months. 4、 每隔三个月清洗冷却水塔。 Clean the cooling water tower every 3 months. 5、 冷却水质不良，请加装Y型过滤器。 Install Y-type filter if the quality of cooling water is not good. 6、 请勿封闭冰水管路循环，不得与其它管路共享。 Do not block the circulation of ice water pipeline and not share with other pipelines. 7、 冷却水塔可加杀藻剂和除垢剂，防防止青苔和水垢。 Algicide and cleaner can be added to the cooling water tower. 8、 冰水系统每隔三个月更换新水，若无法更换请加除锈剂。 Change the water of ice water system every 3 months. If not possible, please add rust remover. 9、 若为气冷式请定期清洗过滤网。 Clean the filter regularly if the chiller is air-cooling. 10、 本机使用R-22冷媒(CHCIF)，请勿私自添加冷媒。 This machine uses R-22 cooling medium (CHCIF), please DONOT add the medium by yourself. 11、 故障产生请依故障指示灯检查系统，如无法排除故障，请来电联系。 Follow the indicator light to check the system if malfunction occurs. If not able to solve, please call us. ※ 附注：冷凝器管路的清洗方法 ※ Annotations: Cleaning method of condenser pipeline (1)．切断电源开关。 Cut the power supply. (2)．关闭冷却水进出口球阀。 Turn off the ball valve of cooling water inlet and outlet. (3)．拆下冷冻机前面板。 Dismantle the front panel of the chiller. (4)．将固定螺丝拆开，卸下圆形盖板，可见铜管。请使用铜刷来回清通即可。 Take the fixe
