Q1:Unable to Reach the Set Temperature

A1:This may be caused by refrigerant leakage, compressor failure, or blockage in the circulation system. It is necessary to check if the refrigerant is sufficient, repair the leakage point and recharge the refrigerant; inspect the status of the compressor and perform maintenance or replacement if needed; clean the circulation system to eliminate blockages.

Q2:Abnormal noise from the water pump or failure to operate normally.

A2:Inspect the condition of the water pump impellers and bearings; replace them if damaged. Check whether the motor connections are in good condition and ensure the power supply is normal.

Q3:Slow Heating/Cooling Rate

A3:Ensure the heater/cooler is functioning properly; it may be necessary to replace the electric heating element or refrigeration element. Check if the heat exchanger is blocked or contaminated—cleaning the heat exchanger can restore its performance. Ensure the refrigerant circulates smoothly; it may be required to inspect and clean the refrigerant pipelines.

Q4:Abnormal Operation of the Compressor

A4:Check if the power supply is stable and meets the equipment requirements. Inspect the compressor for abnormal noise or vibration, which may be caused by damage or wear of internal parts. Clean and inspect the condenser—if dust or dirt accumulates on the condenser, it may cause the compressor to overheat.
