冷水机的开机注意事项

开机注意事项 Startup Notices

1、电源系统： Power supply system:

（1）.将本机电源线之地线接地（黄绿色线）或从机殻螺丝钉接地。

Earth the ground wire （yellow-green wire） of the machine or earth it by the screw of the shell.

（2）.检查电源、电压及电流容量是否符合本机使用 3∮380V50Hz之电源，无熔丝开关（NFB）。

Check if the capacity of the power supply, voltage and current is suitable for this machine to use 3∮380V50Hz power supply and no-fuse breaker.

（3）.将本机电源线接至铭牌上所定之电源。

Connect the power supply wire of this machine to the power supply specified by nameplate.

2、冷却系统：Cooling System:

（1） .冷却水塔是否运转，抽水泵浦转向是否正确，进出水口是否接对。

Check if the cooling water tower works and if the water pumping direction is right, whether the inlet and outlet connect correctly.

（2） .冷却循环水，压力应在1Kg /cm2，压力流量应在13L/min以上。

The pressure of circulating cooling water should be 1Kg /cm2 and the flow should be over 13L/min.

（3）. 冷却水温，不可超过35℃。

The temperature of cooling water should not be higher than 35℃.

（4）.打开本机冷却水出入口球阀，自动补水至水箱（如补充水无法进入水箱，即冷却水压力不够）。

Turn on the ball valve of the cooling water’s inlet and outlet, supplement water automatically （if fail, the pressure of the cooling water is not enough）.

※ 如贵公司所订冷冻机为冰水系统（如用纯水）与冷却水系统水质不同，请自行添加至水箱。

※ If the chiller ordered by your company requires different quality of water （like pure water）, please add it to the water tank by yourself.

※ 如贵公司所订冷冻机的冰水槽移至外部加大，须先把冰水槽加满水位。

※ If the chiller ordered by your company needs to move the ice water tank to the outside and enlarge it, you shall fill the tank with water to the water line.

※ 如贵公司所订冷冻机为气冷式，则不用冷却水塔，只须从后本机补给水球阀补水。

※ If the chiller ordered by your company is air-cooling, then cooling water tower is not needed, just supplement water through the ball valve.

3、检查冰水进出口是否接对。

Check if the inlet and outlet of ice water is connected right.

4、以上事项正确后，方可开机。

Make sure the above items are all right, and then turn the machine on.

5、本机系统注意事项：

Attentions:

（1） .温度勿设定4℃以下，否则冷冻水易冻结胀破蒸发器铜管，产生漏冷媒状况。

The temperature should not be below 4℃, otherwise the cooling water will freeze and swell to break the copper pipe of the evaporator, causing cooling medium leakage.

（2）.温度如设定4℃以下，需添加防冻液于水箱内。

If the temperature is below 4℃, antifreeze should be added to the water

tank.

（3）.本机设有电源相位识别，保护马达，泵浦反转及故障指示电路，如有任何故障将无法启开马达及压缩机。

This machine has power supply phase recognition, motor protection,

pump reversal and malfunction indicator circuit, so the motor and

compressor will not function if there is any fault.

（3） .冻结指示灯亮，压缩机无法启动，泵正常运转。

When the freezing indicator light is on, the compressor will not function but the pump still works.
