1. Introduction
This manual provides essential instructions for the safe and efficient operation and maintenance of your DasMarine CW-3000 Industrial Water Chiller. Please read this manual thoroughly before installation and use to ensure proper function and to prevent damage to the unit or connected equipment. The CW-3000 is designed for thermolysis-type water cooling, suitable for applications such as cooling a single 80W CO2 glass laser tube or below, and for 0.8KW / 1.5KW spindle cooling.
2. Safety Information
- Electrical Safety: Ensure the power supply matches the chiller's requirements (110V). Always disconnect power before performing any maintenance or inspection. Do not operate with damaged power cords.
- Water Safety: Use distilled or deionized water to prevent mineral buildup and corrosion. Do not operate the chiller without sufficient water in the tank.
- Placement: Place the chiller on a stable, level surface with adequate ventilation around all sides to ensure proper heat dissipation. Avoid direct sunlight or heat sources.
- Temperature Range: The chiller operates within a temperature range of 1°C to 45°C. It is a thermolysis type, meaning its cooling capacity is dependent on ambient temperature. It does not actively refrigerate to a set temperature like compressor-based chillers (e.g., CW-5000).
- Emergency Shutdown: Familiarize yourself with the power switch location for quick shutdown in emergencies.

Note: This is a thermolysis-type water chiller. It does not have a compressor and therefore does not actively refrigerate water to a set temperature. The water temperature will generally be close to the ambient room temperature. For active refrigeration, a CW-5000 or higher model is required.
5. Setup Instructions
- Unpacking: Carefully remove the chiller from its packaging. Inspect for any shipping damage.
- Placement: Position the chiller on a flat, stable surface. Ensure there is at least 10 cm (4 inches) of clear space around all sides for proper ventilation.
- Water Filling:
- Open the water injection port on the top of the unit.
- Fill the tank with approximately 8 liters of distilled or deionized water. Do not use tap water as it can cause mineral buildup and damage.
- Monitor the water level indicator on the front panel. Fill until the level is within the "Normal" range.
- Close the injection port securely.
- Connecting Hoses:
- Connect one end of the water hose (not included) to the chiller's "INLET" port and the other end to the "OUTLET" port of your laser or spindle equipment.
- Connect another water hose from the chiller's "OUTLET" port to the "INLET" port of your laser or spindle equipment.
- Secure all hose connections with clamps to prevent leaks.
- Power Connection: Connect the power cord to the chiller's power socket and then plug it into a grounded 110V AC power outlet.
6. Operating Instructions
- Initial Start-up:
- After connecting all hoses and filling with water, turn on the power switch.
- The water pump will start, and water will begin circulating. The "Normal" (green) indicator should light up.
- Observe the water level indicator. The level may drop slightly as water fills the connected equipment. If it drops below the minimum, add more water.
- Allow the chiller to run for a few minutes to purge any air from the system.
- Monitoring:
- Regularly check the temperature display to ensure the water temperature is within acceptable limits for your equipment.
- Ensure the "Normal" indicator remains green. If the "Alarm" (red) indicator lights up and an audible alarm sounds, refer to the Troubleshooting section.
- Shutdown:
- Before shutting down the chiller, ensure the connected equipment (e.g., laser) is also turned off.
- Turn off the power switch on the chiller.
- For extended periods of non-use, it is recommended to drain the water from the chiller and connected equipment to prevent stagnation or freezing.
7. Maintenance
- Water Replacement: Replace the water every 1-3 months, depending on usage and water quality. Always use distilled or deionized water.
- Cleaning the Radiator: Periodically inspect and clean the radiator fins to ensure optimal heat dissipation. Use compressed air to remove dust and debris. Ensure the chiller is powered off and unplugged before cleaning.
- Filter Cleaning: If your model includes a water filter, clean or replace it as recommended to maintain water flow. (Note: Specific filter details not provided, general advice).
- Hose Inspection: Regularly check hoses for kinks, cracks, or leaks. Replace damaged hoses immediately.
- Winterization (if applicable): If operating in an environment where temperatures may drop below freezing, drain the water completely or use an appropriate non-corrosive antifreeze solution designed for cooling systems.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chiller does not power on. | No power supply; Power cord loose; Blown fuse. | Check power outlet and connections; Ensure power switch is ON; Check and replace fuse if necessary. |
| Alarm sounds, red indicator lights up. | Low water level; Water flow blockage; Pump malfunction. | Check water level and refill; Inspect hoses for kinks or blockages; Clean pump if accessible; Contact support if pump is faulty. |
| Water temperature is too high. | Insufficient ventilation; Ambient temperature too high; Radiator fins blocked; Chiller capacity exceeded. | Ensure adequate space around chiller; Operate in a cooler environment; Clean radiator fins; Verify connected equipment's cooling requirements are within CW-3000's capacity. Consider a compressor-based chiller (e.g., CW-5000) for lower temperatures. |
| Water leakage. | Loose hose connections; Damaged hoses or seals. | Tighten hose clamps; Inspect and replace any damaged hoses or seals. |
