My bad, just googled the Nano does not have a rba. (Not confirmed tho)
I assume you're using the OCC which is the pre-made coil head (Its not even economically feasible to get the replacement head which is priced ridiculously in the black market)
Top or bottom of the wick? There's a hole on the side where the juice will flow into the coil head, once it's past that hole, I'll refill.
It's possible to wash the coil, google how to rewick those premade coil heads.
Personally, my advice is use the tank for now if it doesn't come with an RBA, the replacement coil heads when you're done with your supplies is not economically friendly. Source for one that is able to rebuild.
