To get water flowing through any of the Deltec hang on the back protein skimmers please follow the following procedure, once the skimmer is positioned correctly on the aquarium.

1. Shut the orange air controll valve.
2. Remove the collection cup.
3. Using a jug, carefully fill the body of the skimmer with water from the aquarium untill water starts to flow out of the outlet pipe.
4. Replace the collection cup, position it so that it is sitting high in the body.
5. Plug in the skimmer pump. Water should start to be drawn up the inlet pipe.
6. Once water is flowing through the skimmer slowly open the orange air tap until it is in a rough 2 o'clock position.

The skimmer should now be running, if the unit is new or on a new tank it is best to leave the collection cup sitting high up to start with and then lower over the next few days as the skimmer settles.
