Installation of the
Silent Air.

1. Always position the air pump above the water level; otherwise, the pump can fill up with water as a result of the siphoning effect.
2. Make sure that the air pump cannot fall into the aquarium.
3. Never place the air pump on top of the aquarium.
4. We recommend using a non-return valve so that the water cannot flow back into the pump via the air hose. In this case the air pump may be positioned underneath the water level.
5. Connect an air hose (4-6 mm, not included) with an air stone (not included) to each outlet of the air pump.
6. Place the air stone(s) in the aquarium.
7. Turn the air pump on by putting the plug in the socket.
