Overview

CW-3000 Series is professional cooling machine referring to international advanced thermolysis cooling system design, suitable for small water-cooled cooling devices requested machinery.

Model Illustration

Note: This model description only contains the description of the company’s main product codes, not all of them are listed. Please confirm with our company before ordering the specific model, our company has the final interpretation right about it.

Product Outlines & Parts

Note: The above-mentioned product outlines and part names are only for one of the models, and they will be slightly different in different models.

Installation

1. Open the package and check whether the machine is in good condition and whether the accessories are complete.

2. Please ensure that the working voltage of the chiller is stable and normal.
   Because the refrigeration compressor is sensitive to the power supply voltage, the normal working voltage of our company’s standard products is 210~240V (110V model is 100~120V). If wider operating voltage range is necessary, customization is available.

3. Equipment installation conditions and requirements.
   (1) It must be installed on a horizontal surface and not tilted.
   (2)The air outlet of the chiller should be at least 1.5m away from the obstacle, and the air inlet must be at least 1m away from the obstacle (See below diagram).
   (3) Do not install in harsh environments such as corrosive, flammable gas, dust, oil mist, conductive dust, high temperature and humidity, strong magnetic field, direct sunlight, etc.
   (4) Operating EnvironmentAmbient Temperature| Ambient Humidity| Altitude
   ---|---|---
   0~40℃| ≤90%RH| ≤3,000m

(5) Medium Requirements
Cooling medium allowed by the chiller includes purified water, distilled water, high purity water and other softened water. It is forbidden to use oily liquids, liquids containing solid particles, corrosive liquids, etc. Clean the filter element and replace the cooling water regularly (about three months is recommended) to ensure the normal operation of the chiller.
When the chiller is stored with water at room temperature lower than 2℃, it is necessary to add anti-freezer in the chiller water tank. It is recommended to use antifreeze with a concentration of not more than 30% containing ethylene glycol or propylene glycol. After the temperature warms up, change to purified water, distilled water or other suggested cooling media, let the chiller run for 30 minutes to remove the residual antifreezer and drain it, and then refill with unused circulating water.

4. Determine the direction of the pipeline layout according to the water inlet and outlet of the chiller, and ensure that the waterway is clean and free of impurities, so as to prevent impurities from entering the waterway and causing blockage or pump failure.

5. Plug in the power cord and turn on the power switch (It is forbidden to start without water).
   (1) After turning on the power switch, the circulating pump of the chiller starts to work.
   When the new machine is turned on for the first time, there will be more air bubbles in the pipeline, which will cause the machine to alarm occasionally, and it will return to normal after a few minutes of operation.
   (2) After starting the machine for the first time, check if the water pipes leaks immediately.
   (3) After turning on the power, if the water temperature is lower than the set temperature, it is normal that the cooling fan and other devices of the machine do not work. The temperature controller will automatically control the working status of compressors, solenoid valves, cooling fans and other components according to the set parameters.
   (4) 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 off the power and again on frequently.

6. Electrical connection.
   (1) Please select the cable based on the max. rated current indicated on the label of the chiller.
   (2) Recommended reference standard for power cord diameter selection.Rated current/ A| ≤5| ≤10| ≤15| ≤25| ≤35| ≤50
   ---|---|---|---|---|---|---
   Wire diameter (copper wire)/ mm²| 1.0| 1.5| 2.5| 4.0| 6.0| 10.0

Note: This data is provided according to IEC 60204-1 standard and only for reference. Standard cables must be used in the power cord.
(3) The main circuit of the power supply must be equipped with appropriate electric leakage and overload protection devices, and the chiller must be well grounded.
(4) Less than ±10% of power supply voltage fluctuation and less than ±1Hz of frequency fluctuation are allowed, and keep away from electromagnetic interference sources.

7. Fill Water & Exhaust Air
   (1) Fill Water
   After the new machine is turned on, the air in the water pipe is emptied, and the water level of the water tank will drop slightly. In order to keep the water level in the green area, you can add water again. Observe and write down the current water level. After the chiller has been running for a period of time, observe the water level gauge again. If the water level drops significantly, check again if there is leakage in the water pipes.
   ****(2)

Exhaust Air
After adding water for the first time or replacing water, exhaust the air in the water pump to start use, otherwise the equipment will be damaged. The exhaust method is as follows： Method 1: Under the state of shutting down, after adding water, remove the water outlet and connect the water pipe, drain for 2 minutes, and then install it firmly. Method 2：Open the water supply inlet, after starting the machine (water flows), repeatedly press and fold the water pipe several times to drain the air from the pipe.

8. Test-run Check.
   (1)Check whether the pipeline connection is correct, and there must be no bubbling or w ater leakage;
   (2) Check the liquid level of the water tank;
   (3) Confirm that the electrical wiring of the equipment is connected correctly;
   (4) Confirm whether the equipment is grounded.

Alarm & Output Terminal

In order to guarantee the equipment will not be affected while abnormal situation happens to the chillers, the chillers are designed with alarm protection function.

1. Alarm output terminals and wiring diagram
   
   Note: The alarm output port is connected with a set of normally open and normally closed contacts of the relay inside the machine. The working current should be smaller than 3A while the working voltage should be smaller than 300V.

2. Alarm function
