HAPSITE Smart Operating Manual
Figure 15-15 Vent HAPSITE Error Message
The NEG Pump becomes very hot when in operation. The
software-controlled sequence to remove the pump
provides a cool-down period. 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 its 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 inside of the front panel by loosening the
locking ring, then pull the connector straight back.
Do not disconnect the NEG Pump before the Vent
Manifold Has Been Completed message, as the
temperature sensor would then be inaccessible to the
controller.
