Thank you for using the machine from GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD. Please read the installation instructions
carefully before installing and operating and keep it properly.
This installation instructions is not a quality assurance. GUANGZHOU TEYU
ELECTROMECHANICAL CO., LTD reserves the right to the interpretation of
correction of typographical errors, improper mentioned information and product
improvement. The amended content will be reprinted in installation instructions
without notice in advance.
<1> Cautions
1. Please ensure that the power supply and electrical outlet are in good contact
and the earth wire must be firmly grounded!
2. Please make sure there is stable and normal voltage for the working chiller!
As the refrigeration compressor is more sensitive to the power supply and
voltage, so the operating voltage of our standard product is ±10％ of the rated
voltage. If you do need a wider operating voltage range, customization is
available for us.
3. Unmatched power frequency can cause the chiller damage!
Please choose model of 50Hz or 60Hz according to actual circumstance.
4. To protect the pump, it’s strictly forbidden to run the chiller without water in the
storage water tank!
The new machine is packed after draining whole water in the tank, so please
make sure the tank has water inside before machine starting, otherwise it’s
easily to have the pump damaged. When the water level is below the green
(NORMAL) range of the water level gauge, the cooling capacity of our chiller
will go down slightly. Hence please ensure the water level is within the green
(NORMAL) range. To drain through circulating pump is strictly prohibited!
5. Please be sure that the air inlet and air outlet are in good ventilation!
There must be at least 50cm from obstructions to the air outlet which is in the
back of the cooler, and should leave at least 30cm between obstructions and
the side air inlet.
6. The filter gauze must be regularly cleaned!
It’s essential to remove and wash the dust gauze regularly, otherwise chiller
malfunction can be caused by serious blockage.
7. Please pay attention to the effect of the condensate water!
With greater ambient humidity, when the water temperature is lower than the
ambient temperature, the condensate water will generate on the surface of
water circular pipes and the cooled components. If above circumstance
appears, it is recommended to set a higher water temperature or keep pipes
and cooled parts warm.
8. This product is an industrial equipment.For professional use only.

<3> Installation
It is very simple to install this industrial cooling machine. The installation for the
first time 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 water supply lid to feed cooling water.
Observing the water level gauge to feed water slowly, be careful not to have the
water overflowed!
3. According to system conditions, please connect the water inlet and outlet pipe
properly.
4. Plug in power, turn on the power switch. (Do not start up without water in the
water tank!)
(1) The water pump starts working once the power switch is turned on. If “E08” or
“E09”error code is displayed on the upper window of temperature controller,
please adjust the 3-phase wiring connection order
(2) The first running of the chiller may have flow alarm because of bubbles in the
water pipe. It will recover to normal after water pump running constantly for a
while.
(3) If the chiller starts for the first time, you must immediately check whether the
water pipe leaks.
(4) Power switched on, if the water temperature is under the set value, it is normal
that fans and other components of the machine do not work. The temperature
controller will automatically control the working conditions of the compressor,
magnetic valve, fans and other parts based on the set controlling parameters.
(5) As it takes a longer time to start over the compressor and other components,
according to different conditions, the time is range from seconds to minutes, so
do not turn on and off frequently.
5. Check the water level in the water tank.
The first starting up of a new chiller will empty the air in the water pipe, causing
a slight water level decline, but in order to keep the water level in the green area,
it is allowed to add adequate water again. Please observe and record the current
water level, and inspect it again after the chiller running for a period of time, if
the water level drops obviously, please re-inspect the water pipeline leakage.
6. Adjust parameters of temperature controller.
CWFL-3000 series use an new intelligent controller. It works in defaulted
constant temperature control mode for the low temperature end with water
temperature set at 25℃ which can be adjusted as needed. The high temperature
end works in intelligent control mode and it will self-adjust controlling
parameters according to the ambient temperature changes.
Normally users do not need to adjust the parameters. If it is necessary, please
refer to page 6 , “Unit introduction and parameters adjustment.”

感谢您购买广州特域机电有限公司的产品，请在使用前仔细阅读使用安装说
明书，并妥善保管。
本使用安装说明书并非质量保证书，对印刷错误的更正, 所述信息谬误的勘
误，以及产品的改进，均由广州特域机电有限公司随时做出解释，恕不预先通
知，修正内容将编入再版使用安装说明书中。
一、使用注意事项
1、请确保电源插座接触良好并且地线可靠接地！
2、请确保冷水机的工作电压稳定、正常！
由于制冷压缩机对电源电压比较敏感，我公司标准产品的正常工作电压为额
定电压±10％。如果确实需要更宽的工作电压范围，可以另行定制。
3、电源频率不匹配会导致机器损坏！
请根据实际情况，使用 50Hz 或60Hz 的机型。
4、为保护循环水泵，严禁无水运行！
新机装箱前都排空了储水水箱，请确保水箱注水后再开机，否则水泵极易损
坏。当水箱水位在水位计绿色（NORMAL）范围以下时，冷却机制冷量会轻
微下降，请保证水箱水位在水位计的绿色（NORMAL）范围内。严禁使用循
环泵排水！
5、请确保冷水机入风、出风通道顺畅！
冷水机上面的出风口距离障碍物要留有 50cm 以上的距离，侧面的入风口
离障碍物要求距离在 30cm 以上。
6、入风口的滤网必须定期清洗！
必须定期拆洗防尘网, 防尘网严重堵塞会引起冷水机故障。
7、请注意冷凝水的影响！
当水温低于环境温度，并且环境湿度较大时，循环水管与被冷却器件表面会
产生冷凝水。当出现以上情况时，建议调高水温或对水管与被冷却器件进行保
温。
8、本产品为工业设备，请勿让非专业人士操作。

三、 安装说明
冷水机安装使用非常简单，新机首次使用可按以下步骤进行：
1、打开包装，检查机器是否完好，附件是否齐备。
2、拧开机器注水口，加入冷却水。
加水时应同时观察水位计的水位慢慢加水，注意不要让水溢出！
3、根据设备情况接好出水管、入水管。
4、插上电源线，打开电源开关。（严禁无水开机！）
（1）打开电源开关后，水泵会立即启动。如果温度控制器上显示窗显示“E08”
或“E09”故障，请调整三相电源的接线顺序。
（2）新机第一次开机时管路中会有较多的气泡导致机器偶尔流量报警，水泵连
续运行数分钟后就会恢复正常。
（3）第一次开机后，必须马上检查水管管路有无漏水。
（4）按温控器开关键启动制冷系统后（运行指示灯亮），如果水温低于设定温度，
机器的风扇等器件不工作是正常现象。温控器会根据设定的控制参数自动
控制压缩机、电磁阀、风扇等器件的工作状态。
（5）由于压缩机等器件有一个较长的启动过程，根据不同的工况从几十秒到数
分钟不等，所以不要频繁启停冷水机。
5、检查水箱水位。
新机开机后排空了水管中的空气，水箱水位会略有下降，为了保持水位在
绿色区域，可以再次适量加水。观察并记下当前的水位情况，等冷水机运行
一段时间后再次观察水位计，如果水位下降明显，就要再次检查水管管路的
渗漏情况。
6、调整温控器参数。
CWFL-3000 双温单泵系列冷水机使用的智能温控器低温端出厂设置为恒
温控制模式，水温设定为 25℃，用户可以根据需要调整。高温端为智能控制
模式，它会根据室温的变化自动调整控制参数。
一般情况下，不需要调整控制参数，如确实必要的，可参考第 20 页《机
组介绍与参数调整》。
