Never reverse the inlet/outlet connections on the low-temperature circuit. Doing so will starve the QBH of cooling, leading to thermal lensing and permanent fiber damage.
💡 If you can’t find the full manual immediately, at least locate the quick start guide on the chiller’s side panel – it lists error codes and basic setup. Always power cycle the unit after changing water or filters before restarting your laser. cwfl-6000 manual
By default, it uses an Intelligent Control Mode (T-803 controller) which adjusts water temperature based on ambient room temperature. 🛠️ Maintenance & Troubleshooting CWFL-6000 Manual - 20230104094939 | PDF - Scribd Always power cycle the unit after changing water
Clean the dust gauze/filter screen to prevent blockage and overheating. often lower temperature
The manual strictly warns against cross-connecting these lines. The laser source typically requires a precise, often lower temperature, while the cutting head may have different thermal load needs. The CWFL-6000 allows you to set two independent temperatures, preventing condensation inside your expensive laser hardware.
: Includes clear intervals for cleaning dust filters (quarterly) and checking water connections (weekly) to prevent condensation and leaks. Error Codes
Always wait at least 5 minutes before restarting the chiller after a shutdown to allow refrigerant pressures to equalize.
