4 Select Activate Neg.
5 When prompted on the Front Panel, enter the Serial Number of the New NEG
Pump.
6 The NEG Pump will take approximately 18 hours to activate. The process is
totally automated and does not need any other interactions until the process is
complete.
7 Once the NEG Pump is activated, remove the HAPSITE from the Service
Module. (Power the HAPSITE with battery or an external power supply.)
Refer to section 14.8, Detaching the HAPSITE, on page 14-17 for instructions
on safely removing the HAPSITE from the Service Module.
NOTE: When completed, the Activate NEG process will automatically detach the
HAPSITE from the Service Module.
8 Repeat the leak check portion of this process. Instead of checking for a leak
between the Analytical Module and Service Module, check the VI valve on
the bottom of the HAPSITE where the Service Module physically attaches.
(Refer to section 15.7.5, Part 4: Leak Check of the Vacuum System, on page
15-32.)
9 If there is a leak, the leak must be sealed by repeating section 15.7.2, Part
1: NEG Pump Removal, on page 15-17 through section 15.7.4, Part 3: Install
the New NEG Pump, on page 15-27, the leak check in section 15.7.5, Part 4:
Leak Check of the Vacuum System, on page 15-32 repeated and the NEG
Pump reactivated by performing section 15.7.6, Part 5: Activation of the NEG
Pump, on page 15-38.
