MAN 0376

Exhaust Port

Any gas pumped out of the vacuum chamber exits the unit through the exhaust
port.

Validation Connector

Depending on the model, there may be a 2-pin receptacle labelled "Validation"
located next to the power switch. This receptacle and its associated screw-lock plug
allow a validation signal from the Vacuum Degasser's control circuit to be sent to a
computer or data system. This validation output indicates vacuum level (see

Spec-

ifications

section for details).
