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.
