2. Sicherheitshinweise

Read all safety warnings and instructions carefully before operating the chiller. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Stellen Sie sicher, dass der Kühler auf einer stabilen, ebenen Fläche steht.
• Connect the chiller to a properly grounded power outlet.
• Do not operate the chiller with damaged power cords or plugs.
• Keep the chiller away from heat sources, flammable materials, and direct sunlight.
• Ensure adequate ventilation around the chiller to prevent overheating.
• Do not immerse the chiller in water or other liquids.
• Use only distilled water or recommended laser coolant. Do not add tap water directly.
• Always disconnect power before performing any maintenance or refilling the water tank.
• Keep children and unauthorized personnel away from the operating chiller.

4. Einrichtungsanweisungen

Follow these steps for initial setup of your water chiller.

1. Auspacken: Carefully remove the chiller from its packaging. Inspect for any damage during transit.
2. Platzierung: Place the chiller on a flat, stable surface in a well-ventilated area. Ensure there is at least 20 cm (8 inches) of space around the unit for proper airflow.
3. Wassertank auffüllen: Unscrew the water injection port cap (1 in Figure 4). Fill the tank with approximately 6 liters (1.6 gallons) of distilled water or OMTech laser coolant. Monitor the water level gauge (6 in Figure 4) to ensure the level is within the green zone. Do not overfill.

4. Wasserschläuche anschließen: Connect the water inlet of your laser machine to the Cooling Water Outlet (4 in Figure 4) of the chiller. Connect the water outlet of your laser machine to the Cooling Water Inlet (5 in Figure 4) of the chiller. Secure all connections to prevent leaks.
5. Stromanschluss: Connect the power cord to the Power Socket (2 in Figure 4) on the chiller and then plug it into a grounded electrical outlet.

5. Bedienungsanleitung

Operating the CW-5200 chiller is straightforward once properly set up.

1. Einschalten: Flip the Power Switch (1 in Figure 3) to the 'ON' position. The chiller will start, and the temperature display will illuminate.
2. Initial Circulation: Allow the chiller to run for a few minutes to circulate the water and remove any air bubbles from the system. Check the water level gauge again and add more water if necessary.
3. Temperaturüberwachung: The digital display (2 in Figure 3) shows the current water temperature. The chiller is designed to maintain the water temperature within 0.3°C of the set point.

4. Laserbetrieb: Once the chiller has reached a stable operating temperature, you can begin operating your CO2 laser machine. The chiller will automatically regulate the water temperature to prevent overheating of the laser tube.
5. Ausschalten: After use, turn off your laser machine first, then switch off the chiller using the Power Switch.

6. Wartung

Regular maintenance ensures the longevity and optimal performance of your chiller.

• Wasserersatz: Replace the cooling water every 1 to 3 months, depending on usage and environmental conditions. Always use distilled water or OMTech laser coolant.
• Clean Radiator Fins: Periodically clean the radiator fins (7 in Figure 4) to ensure efficient heat dissipation. Use a soft brush or compressed air to remove dust and debris.
• Wasserstand prüfen: Regularly check the water level gauge and refill if the level drops below the green zone.
• Drainage: Use the water drain port (8 in Figure 4) to empty the tank when replacing water or storing the unit.

• Schläuche prüfen: Periodically inspect all water hoses for kinks, cracks, or leaks. Replace any damaged hoses immediately.

7. Fehlerbehebung

This section addresses common issues you might encounter with your CW-5200 chiller.

• Chiller Not Turning On:
  • Check if the power cord is securely plugged into both the chiller and the wall outlet.
  • Vergewissern Sie sich, dass sich der Netzschalter in der Position „EIN“ befindet.
  • Check the fuse in the power socket (2 in Figure 4). Replace if blown.
• Wasser zirkuliert nicht:
  • Stellen Sie sicher, dass der Wasserstand ausreichend ist.
  • Check for kinks or blockages in the water hoses.
  • Verify that the pump is operating (listen for pump noise).
• Alarm bei hoher Wassertemperatur:
  • Ensure the chiller's radiator fins are clean and not obstructed.
  • Verify that the ambient room temperature is not excessively high.
  • Check if the cooling fans are operating.
  • Stellen Sie sicher, dass der Wasserstand ausreichend ist.
• Wasserleck:
  • Inspect all hose connections for tightness.
  • Check hoses for any damage or cracks.
