The Icon and BioSpec adapters contain a water/air heat exchanger. When connected the first time to the Air Circulation System in combination with the water (options), air bubbles in the heat exchanger of the adapter might prevent water flow. Prior to mounting the adapter to the animal preparation table, connect it to the warm water circulation, switch the pump on, and hold the adapter vertically.

Turn it around a couple of times from vertically upward to downward and vice versa until you feel warm water flowing at the output hoses and no air bubbles are to be seen in the transparent water hoses.
