advanced thermolysis cooling system design, suitable for small
water-cooled cooling devices requested machinery.
1. Specific disconnection alarm security protection.
2. Hermetic type water tank, water is available for a long time used.
3. Real-time temperature monitoring, accurate knowledge of heating devices
working condition.
4. Professional air-cooled forced radiator with strong heat dissipating
capacity and difficult to be blocked up.
5. Equipped with alarm output port to protect sensitive components quickly.
6. High cost performance, low failure rate.
7. There are several options of power supply, complete in specifications.
<2> CAUTION
1. It is strictly forbidden to plug and run the cooler without feeding water.
2. Cooler should be placed in a well-ventilated, dry environment place and
away from heat sources. Please keep at least 30cm from obstructions to the
air outlet which is in the back of the cooler, and should leave at least 10cm
between obstructions and air inlets of two sides.
3. The cooling water must be drained if the cooler is out of use for long time or
before being transported.
4. To protect laser tubes , the radiator fan of cooler will suspend to work when
water temperature is lower ( about 10℃ ) , and it will restart to run when
water temperature rises to higher ( about 20 ℃).

2. The first installation
It is very simple to install this industrial cooling machine. The first time
installation of the new machine can be carried out by following steps.
1. Open the package to check if the machine is intact and all the necessary
accessories are completed.
2. Open the injection port, then add cooling water.
3. According to system conditions, connect the water inlet and outlet pipe
well.
4. Plug in power, turn on the power switch. (Do not allow the water overflow)
5. Check the w ater level of the water tank again. (It should be 80-150cm from
the surface of water to the injection port)

一、 功能特点简介
CW-3000 系列是参照国际先进散热型冷却系统设计制造的
专业冷却机，适用于小型水冷散热设备。
（ 1） 特有断流报警安全保护功能。
（ 2） 密闭式水箱，一次加水长期使用。
（ 3） 实时温度监控，准确掌握发热器件工作状态。
（ 4） 专业散热器强制风冷，散热量大，不易堵塞。
（ 5） 设有报警输出端口，可快速保护敏感元件。
（ 6） 性能价格比高，故障率低。
（ 7） 有多种电源的机型,规格齐全。
二、使用注意事项
（1）冷却机在没有加水的情况下严禁通电开机！
（2）冷却机的安放位置应尽量选择通风良好、干燥的环境,远离其它
热源。机器后面的出风口距离障碍物 30cm 以上，两侧的入风口
距离障碍物 10cm 以上。
（3）冷却机在长期不用或运输时必须排空冷却水。
（4）为保护发热器件,冷却机在水温较低时（约 10℃）,散热风扇会
暂停工作,而当水温回升到较高时（约 20℃）,散热风扇将继续
工作。
