New setup for GWeike 1290, Couple of questions,

Hey guys,

So I didn't receive a detailed manual... and can't get ahold of one... as G Weike told me to look at the youtube Video of a setup of another machine... So I thought I would ask here! Apologies if these are repeats {I searched I promise you}

1) What distance should I put the RECI tube from the first mirror?

2} I use the cap that came on the RECI tube to shield the High voltage line from shorting correct?

3} The "manual" I did get says I should find the copper wire and ground it into the earth... Wouldn't these machines be grounded though the ground plug it uses to plug in?

4} What is the USB wire that goes to oneof the boards in the electrical area of the machine? Not the one that goes to the exterior marked "USB" I assue I would transfer files to... There is another one wrapped inside the machine.

5} What temp do you set the CW-5000 chiller to? I am in Vancouver and it is a chilly 6C/ 42 F ?

Thanks in advance!
