Hi Michael. I don't saw your comment. Thanks for the warning.

I tried it for a quick moment only to check if controller was working after the buy.

I need to prepare the vacuum system with all correct conecction now. Already I have one roughing pump to make preliminary vacuum. I will follow the next steps:

I'm going to make rough vacuum with turbo->chamber valve opened but the valve for the roughingpump->turbo closed.

Later when 1*10-3 is reached I will close turbo->chamber valve, start pump for the turbo and then open the roughingpump->turbo valve.

Later I will start the turbo.

Later I'm going to close the roughingpump->chamber valve and then open the turbo->chamber valve.

I will make the system and steps described in the next youtube video:

Be careful with your turbo!  Operating without a roughing pump and in open air can be destroy it.  There's nothing quite as gut wrench is hearing one spin up and suddenly go chug and die.

  Are you sure? yes | no
