A 4 stage RODI set up would normally be sediment filter, carbon block, RO membrane and then DI canister. With a 5 stage you probably would have dual sediment filters or carbon blocks, the RO and then the DI.

+1 The DI, would be your last stage.

What I did was I installed the new canister first with the sediment filter and then into two carbon blocks into the dual ro membranes and the lastly the di resin. Thats how BRS recommended it on their video

You nailed it. Remember, once the DI resin turns brown (BRS sells color-changing DI resin) you should replace it. With regular use, this means every 6 - 8 months or so.
