Why is my Grundfos pump noisy?

How do I get rid of an airlock in my water motor?
In order to blast the air lock out of position all you have to do is open the two taps (the main tap and the air locked tap) and allow the pressure of the mains water to force the air back out of the locked tap. Leave to run for several minutes and then make sure to turn off the air locked tap first.

Which is the correct direction for a Grundfos central heating pump?
The direction of flow of the pump will always be as marked by an arrow on the body of the pump, no matter which way the head is orientated. The circular face of the pump should never face downhill or the pump will wear much more rapidly than it should. This pump faces horizontally, which is correct, but facing slightly uphill would also be fine.
