pressurized when the cover is removed. The scrub module
has been designed to require this tube to be disconnected
before removing the cover as a safety precaution.
4. Loosen the four thumbscrews (shown in FIGURE G-2) and remove
the cover plate to gain access to the bottles (FIGURE G-3). Note that
the thumb screws are captive; they remain attached to the cover plate.
