Ro/di arrives tomorrow, proper maint discussion

Okay so, besides hooking it up what should I do before my first waterchange? It's a refurb 4stage from spectrapure found here:

I've read hooking it up and removing all filters and run it with one filter at a time to rinse them before first operation. Should I do this for the front and back of each filter? An if so is 5g each rinse good? What else should I be looking for? What is a good psi range before I should look into a booster?



Other weekly/monthly/seasonal maintenance? Storage procedures?
