[Newbie] Beer dispenser

[MikeMelga]

Hi everyone :)

I am new to this forum and I know absolutely nothing about the beer brewing world.
I ended up here because I am making some remodeling on my house and I am building an outside bar (kinda).
I bought an used Cornelius Maxi 110 which I guess is enough for my needs and during my searches for guides and experiences this site always came up :)

So... could you please help a complete newbie?

My goal is to assemble a fully working beer dispenser. I will be using commercial craft beer and I have some questions that I could use your advice:

1 - My Maxi 110 does not have any temperature regulator (that I see). What is default temperature output?

2 - I need to buy a CO2 Regulator. Any advice on brands or where to buy?

3 - I need to buy a faucet. Any advice ?

4 - Which lines should I use? 3/8" or 3/16"? I heard that using 3/16 works as a pressure reducer. Is this right?


I read somewhere that you could additionally chill the beer by having it pass through the recirc line. Isn't the
recirc line filled with water?


Any help would be most welcome :)

Thanks

Regards,
Mike
