标题冷水机安装的注意事项

一、     安装注意事项

Installation Notices

1、冷却水塔吨数不得低于冷冻机吨数，且需考滤安全系统，故要大于冷冻机吨数的30%

如冷冻机为10RT，冷却水塔须为15RT……经此类推。

Tunnage of cooling water tower should be more than that of the chiller by 30% considering the security system.

For example, if the tunnage of the chiller is 10RT, then the cooling water tower should be 15RT…and the like.

2、冷却水塔之水管径不得小于冷冻机之出口管径。管径大小可参考规格表。

The diameter of the cooling water tower pipe should be larger than the outlet pipe of the chiller. Refer to the size listed in specification.

3、冷却水塔须安装在室外通风良好之场所，且距离冷冻机不得远于20米，若超过20米其管径选择须大于冷冻机冷却出入口。

如冷冻机为10RT，冷却水出入口径为1-1/2＂,若距离冷却水塔为30米，其管径须选择2＂。

The cooling water tower should be installed in outdoor place with good ventilation, ａnd the distance from the chiller should be within 20 meters. If it is over 20m, the pipe diameter should be larger than that of the chiller’s inlet ａnd outlet.

For example, the chiller is 10RT, cooling water inlet ａnd outlet caliber is 1-1/2＂, if the distance from cooling water tower is 30 meters, then the pipe diameter should be 2＂.

4、冰水系统管路不得高于冷冻机的冰水出入口，否则停机后水箱会溢水。（请于冰水出口加装逆止阀）

Ice water system pipeline should be lower than that of the chiller’s inlet ａnd outlet, otherwise water will overflow from the tank after shutting down the machine （please install check valves in the ice water outlet）.

5、冷冻机安装处不得完全靠墙壁，须距离50公分以上，以利保养维修。

The chiller should not be installed alongside the wall. It must be away from the wall by more than 50 centimeters for maintenance.

6、气冷式冷冻机须放置在空气流通、粉尘少的地方。

Air-cooling chiller should be deposited in a place with good ventilation ａnd less dust.

7、外主电源线不得小于冷冻主电源电线，其它电源开关不得小于冷冻内之无熔丝开关世界安全倍数，亦不得大于50%。

For the no-fuse breaker’s world safety multiple, the outside main power supply wire should be higher than the freezing main wire, ａnd other power supply switch should be higher than freezing inside switch but should not be more than 50%.

二、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
