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.

Battery Replacement with Drop-in Battery Holder

The PPS, RAS, and WTS-LV samplers have drop-in battery holders for user replaceable 'D' cell alkaline batteries. The Sediment Trap has a drop-in battery holder for 'C' cell alkaline batteries.

Correct battery orientation is critical when using the drop-in battery holder.

The instructional video "Replacing the WTS-LV Battery Holder" explains the correct battery orientation when using a WTS-LV drop in battery holder. The process works the same for other sampler drop-in battery holders.
