A few thing you will need to properly bleed the system is a Flashlight, a tub or small plastic basin of some sort, easy access to the entire cooling system.

After you get all that and are ready to begin, take the pump and place it in the basin. Pour you coolant (PUMP MUST BE SUBMERSIBLE!!!!!! IF IT ISN'T YOU WILL ELECTROCUTE YOURSELF IF YOU DON'T KNOW DON'T TRY IT!!!!) so it covers the pump housing ( the area the impeller is in, not the entire pump).

Hook up the "Out" part of the pump to the out going coolant line, and leave the intake area on the pump open and well submerged in the coolant.  Now with a vacuum or your mouth prime the pump by sucking in on the return end of the hose, this will flood the inside of the pump and prime it. ( do not use your mouth if you are using car Antifreeze  Ethyne Glycol is lethal.

Plug in the pump and watch over your coolant system to make sure coolants not pouring all over your video cards :).  Tuck the return line then in the basin AWAY from the intake on the pump.  Run it that way for about 30 min, so it will let all the air circulate out of the system. While this is going on take your flash light and check the lines for any signs of bubbles.  if you find any "flick" the area of tube with your finger and it should move the air out of the system.

Now Power off the pump leaving the exhaust line under the coolant level (stops any air from being sucked back in).  now check if any air pockets show them selfs. Normally the pump will have some, and so will the coolant blocks. shake and tap both to dislodge any air in them. then turn on the pump once again.  DO this 2 more times and let it run as an open system for about 2 hrs.
