monitor and damaging it. The bottle is
installed on the Environmental Enclosure when it is shipped. If the bottle is
removed for cleaning, follow these precautions when re-installing:
•
Before screwing the bottle into inner inlet ring, be sure that the O-ring
found in the bottom of the threaded hole is greased. This ensures an air-
tight seal.
•
When threading the bottle into the inlet be careful not to damage its
threads. Figure B-5 demonstrates how to install the water trap correctly.
•
Make sure the bottle has been tightened securely.
