Troubleshoot the E1 Ultrahigh Room Temperature Alarm for Fiber Laser Chiller CWFL 2000

If your fiber laser chiller CWFL-2000 triggers an ultrahigh room temperature alarm (E1), follow these steps to resolve the issue. Press the "▶" button on the controller and assess the ambient temperature ("t1"). If it surpasses 40℃, consider optimizing the chiller's environment to 20-30℃. For normal ambient temperatures, ensure proper chiller placement with sufficient ventilation. Clean the dust filter and condenser using an air gun or water (maintaining pressure less than 3.5 Pa and avoiding fins). Examine the ambient temperature sensor's functionality, conducting a temperature accuracy test in 30℃ water. If discrepancies arise, it indicates a faulty sensor. If the alarm persists, please contact our customer service at [e-mail] for assistance.
