chamber.
A flexible vacuum line connects the CryoBay vacuum
system to the vacuum flange of the probe. When not in
use, the vacuum line should be capped with a NW25
blanking plate, O- ring and clamp.

Verify that the O- ring and clamp are correctly seated.
The two mating flanges should be parallel to each
other.
The vacuum clamp is magnetic. Use appropriate care when handling it
around the magnet
