Putting It Together
Connect the pump water outlet fitting to one of the radiator fittings, preferably the lowest one in your configuration. This setup helps get air out of the system. From the higher radiator fitting, connect a hose to the water inlet fitting on the water block. From the water outlet fitting on the water block, connect a hose to the water inlet fitting on the pump. You can also add a water reservoir (available at any CPU water-cooling parts store online) to the water circuit.
Always cut a hose perpendicular to its length; any angled cut will make a poor seal and might leak.
To charge the system with water, place the pump in a reservoir or bucket. Fill this reservoir with distilled (or better, de-ionized) water. Make sure that the entire pump, along with fittings, is submerged. Next, disconnect the hose from the water inlet fitting in the pump and place it to the side of the pumpmeanwhile keeping everything under water. (Some people recommend adding an anti-algae additive at this point.)
Turn on the pump. Once the system is full of water and no air remains, reconnect the hose to the pump water inlet fittingwithout turning on the pump. Once the hose is connected, you can turn off the pump. Finally, take the pump out of the reservoir and place it on a thick towel to dry. Figure 3 shows the final result, with the radiator mounted alongside our case.
