1. Connect the supply source to one connection of the Aar-O-Vent.
2. Connect suction piping of the pump to the other connection of the Aar-O-Vent.
3. The air vent, the blow down valve and the skim valve should be run to an
adequate drain.
4. Once all connections are made, allow the system to completely fill with water.
Opening the skim valve will speed up this process.
5. After the unit is completely filled, the Aar-O-Vent is ready for operation.
