Now,I show you some simple judgement and troubleshooting
1. It may be temperature controller of malfunction, the user can contact S&A after-sales department for support: 4006002093 ext.2
2. You choose wrong chiller model (not enought cooling capacity),so it's not able to cool down the water for metal cutting machine. In this situation, it should be another chiller model with larger cooling capacity.
3. After long term running without cleaning and too must dust accumulating, please clean the interior dust of the chiller
