DAHAN L6 (L2) machine installation - water chiller

This video is an installation guide for DAHAN L6, L2, L7, L3 series water chillers of the same/similar model.
The key point is to pay attention to the installation of water inlet and outlet pipes. The water flow between the water chiller and the laser tube should form a water circulation.
After connecting, take photos or videos and send them to DAHAN factory for confirmation. To avoid losses caused by incorrect connections.
