The pump is not self priming and hence i s only capable of sucking through small volumes of air. 3. Push the male valved fitting of the filled tube into the inlet of the cooling circuit. Make sure that the inlet of th[...]

2. Servicing t he liquid coolin g circuit 7. Uncouple the two plastic tubes. Note: Make sure that both ends of the plastic tubes in the bottle remains immersed until the plastic tubes are uncouple from the li quid c ooli ng cir cuit . Tip : Sometimes a little cooling liquid will be spilled. Wrap a small cloth around the valved fitting while uncoupl[...]
