CAUTION
The NEG Pump becomes very hot when in operation. The
software-controlled sequence to remove the pump
provides a cool down period time to cool. This
sequencing must not be bypassed. In addition to the
danger of burns from handling the hot flange, the
reactive metal alloys within the pump can ignite if
exposed to atmospheric pressure while hot. If this should
occur, drop the pump into a bucket of sand and cover the
hot NEG Pump with more sand. If this is not practical, set
the pump on the black plastic base, on a non-flammable
surface. The NEG Pump will burn out in a few minutes.
4 When the screen shows Vent Manifold Has Been Completed, unplug the
NEG Pump’s black cable from the front panel by loosening the locking ring,
then pull the connector straight back.
WARNING
Do not disconnect the NEG Pump’s black cable before
receiving the "Vent Manifold Has Been Completed"
message. Doing so will disconnect the temperature
sensor and the NEG Pump will be hot.
