CAUTION
If the NEG Pump is to be reinstalled, it must be removed
when it is at room temperature. If the NEG Pump has been
used within 8 hours, let it cool overnight prior to removal.
1 This procedure requires the use of a Service Module. The HAPSITE should be
physically placed on the Service Module and attached. Refer to
section 2.8,
Service Module, on page 2-19 and Chapter 15, Service Module for more
information on setting up and using the Service Module.
2 If the NEG Pump is hot from recent use, let the system cool overnight before
performing this procedure. Refer to
section 16.7.2, Part 1: NEG Pump
Removal, on page 16-23 .
WARNING
Burn hazard. Do not bypass the cool down step! The NEG
Pump will react with air when it is hot. This will cause it
to become very hot and possibly create sparks.
3 Vent the HAPSITE by choosing Vent HAPSITE on the Service window of the
Service Module tab in the Properties window. This starts a process which
includes monitoring the cooling of the NEG Pump. See
Figure 16-48 .
