If your TEYU S&A fiber laser chiller CWFL-2000 triggers an ultrahigh room temperature alarm (E1), follow these steps to resolve the issue. Press the "▶" button on the temperature controller and check the ambient temperature ("t1"). If it exceeds 40℃, consider changing the water chiller's working environment to the optimal 20-30℃. For normal ambient temperature, ensure proper laser chiller placement with good ventilation. Inspect and clean the dust filter and condenser, using an air gun or water if needed. Maintain air pressure below 3.5 Pa while cleaning the condenser and keep a safe distance from the aluminum fins. After cleaning, check the ambient temp sensor for abnormalities. Perform constant temperature testing by placing the sensor in water at around 30℃ and compare the measured temperature with the actual value. If there's an error, it indicates a faulty sensor. If the alarm persists, contact our customer service for assistance.
