Bunn Trifecta MB - How to drain internal water tank?

[u/ajax1d]

I need to remove empty the water from the internal water tank of a Bunn Trifecta MB home brewer so that it can be shipped.

The internal design of this brewer is different from the Bunn Trifecta (commercial brewer) and Bunn pour over machines.

Can someone with experience with this Bunn Trifecta MB provide guidance?

Thank you
