Barney, I just got my sundace2, and the instructions. Your not missing much. there was no info on how the supposed "bypass" works... and the only other instruction was it goes on top.....
There is some info on pollen collection in general, like collect it daily if possible, and then freeze it.. as well as general info on pollen collection.
Also, don't leave it on constantly.... they recomend 2 weeks on and 2 weeks off..... pollen collection takes food away from the hive which slows its growth.
I think it was BJORN here on beemaster who even suggested pellen collection as a method of swarm control as it slows hive development so much..... (if it wasn't BJORN my apologies, it was a great statement though)
