RESTARTING THE FLUVAL

11. Open the OUT Valve First

12. Then open the IN valve. If the valve is below the aquarium water level, water should begin to siphon from the filled input tube and exhaust air through the OUT hoses.

13. If water does not flow immediately, remove the hose from the spray bar and blow excess air out of filter case and intake tube. When siphoning starts, reassemble exhaust to hose. Connect power and ensure all is working correctly.
