Steam Class 08 Vacuum Chamber Drain

I'm having a complete mental blank here, I can't find the drain valve for the vacuum chamber for switching from vac to air modes, could someone remind me where it is please?

 

on the Scotsman?

 

It is hiding here:

 

Brilliant, thank you

 

My error did not see rather missed 08 in the Title, I was looking in the post it's self.
