RAS-500 Pre-deployment and priming
In this video, we review pre-deployment procedures and priming on the RAS-500.
Note: The RAS priming process shown in this video has been modified. Rather than injecting water through the exhaust tube to get the pump going in reverse, we now recommend elevating the reservoir (bucket, container, etc) of your priming water.
