HAPSITE Smart Operating Manual
14.10 Storing the Service Module
When not attached to the HAPSITE, the Service Module should be stored with the
aluminum storage plug in place. Storing the Service Module in this configuration
includes a Pump Down procedure which turns on the Roughing pump for 60
seconds to create a partial vacuum. The vacuum holds the aluminum storage plug
in place and protects the Service Module from dust, debris, and moisture, all of
which can negatively affect the pumps in the Service Module.
NOTE: If the HAPSITE is Attached to the Service Module, the Service Module
must first be Detached. Refer to
section 14.8, Detaching the HAPSITE, on
page 14-17 before proceeding.
HINT: The HAPSITE is considered Attached if the HAPSITE is docked on the
Service Module, and the Turbo pump is running at a speed greater than
0 Hz.
Clean any debris or dust from the black rubber o-ring using a lint-free wipe. This
will help ensure that a good seal to the aluminum storage plug is achieved, allowing
the system to maintain vacuum more effectively. See
Figure 14-35 shows the o-ring
being cleaned.
HINT: When cleaning the Service Module rubber o-ring, use a lint-free wipe. Wipe
the top of the o-ring, following the contour to clean the entire top exposed
section. Avoid pushing dust or debris into the middle opening to the pumps.

After cleaning the rubber o-ring, make sure there are no cuts. Also look for any
visible cracking of the o-ring. If the o-ring is damaged, the o-ring may need to be
replaced.
