If the workshop ambient temperature drops below 0°C, add specialized laser-grade antifreeze (such as Dowfrost or Teyu-approved formulations) to prevent the water from freezing and cracking the internal plumbing or the laser's internal tubes. Never use automotive antifreeze.
Avoid turning the power off and on frequently to prevent compressor damage. Common Alarm Codes System Response E1 Ultrahigh room temperature Alarm sound E2 Ultrahigh water temperature Alarm sound E3 Ultralow water temperature Alarm sound E4 Room temperature sensor failure Compressor/fans shut down E5 Water temperature sensor failure Compressor/fans shut down E6 External alarm input (Water flow) System shut down
If you need to take the chiller out of service or ship it to a new facility: Turn off the power and unplug all electrical cables. Disconnect all external water hoses.
The manual contains several bold warnings that are vital for operator safety:
Keep the chiller running 24/7 so the water constantly circulates. cwfl-6000 manual
Fill the tank until the water level reaches the green zone on the visual level gauge located at the back of the unit. 3. Water and Electrical Connections Plumbing Connections

Ambient temperature exceeded 43°C. Improve room ventilation. Ultra-high water temperature
Water temperature dropped too low (often during startup in cold climates). If the workshop ambient temperature drops below 0°C,
Ensure the chiller is on a level, stable surface. Piping Connections
⚠️ CW-6000 (single circuit) or CWFL-5000/8000 (different power ratings).
Replace the internal ion exchange filters and PP cotton filters to maintain water purity.
One of the most valuable sections of the covers remote communication. Your chiller can talk to your laser controller via RS485 using Modbus RTU protocol. This allows the laser to auto-shutdown if the chiller fails. Common Alarm Codes System Response E1 Ultrahigh room
Observe the water level gauge on the back of the unit. Stop filling when the needle reaches the (Normal level).
Dedicated to cooling the QBH optics/output connector. 2. Unpacking and Pre-Installation Requirements
Explain the best to prevent freezing/corrosion
Usually occurs in winter. Add a chiller heater or adjust ambient space. Room Temp Sensor Failure Open or short circuit in the ambient sensor. Inspect sensor wiring or replace the ambient sensor probe. E5 Water Temp Sensor Failure Main water loop temperature sensor failed. Inspect or replace the water temperature sensor probe. E6 Water Flow Alarm Water level is low, or there is an external hose kink.
