Caution: It’s important that there is no air inside the tube. The pump is not self priming and hence is only capable of sucking
through small volumes of air.
4. Push the male valved fi tting of the fi lled tube into the female valved fi tting at the heat exchanger. This is the entrance of the liquid
cooling circuit. Make sure that the inlet of the fi lled tube remains immersed and that the full bottle is located above the projector.
