C.A.P xgc-1e help please

i really like it and plan on getting it by this weekend i just have a few questions

1) when using a co2 tank do i just connect it to the controller?

2) is there a separate plugs for day/night or can i have say my fan plugged into one plug and it will have it kick on and off in day/night hours when needed

3)do i just plug this into a outlet? or is there wiring

4) do you think i should get this refurbished one for 450 with shipping and it comes with a 5yr warranty
