1:Firstly, connect the four adapters to the chiller and ice bath respectively

2:Check if the quick connector of the hose is loose, you can unscrew it and tighten it again

3:The water in the ice bath needs to exceed the chiller's outlet

4:Check if the hose at the inlet of the chiller is filled with water. If not, remove the hose and lift it up to the ice bath before slowly lowering it down. This will allow the air in the hose to be expelled, fill the hose withwater, and then connect it to the chiller
