b. Press firmly on the tool and turn it counterclockwise to loosen the window.
Continue loosening the window until it is free. If you tip the tool upward, it will
support the window so you don't have to handle it directly.
NOTICE Use nitrile gloves to handle the window and handle it by the rims only.
(Avoid touching the window surfaces even when wearing gloves.)
c. If the window is still usable, grasp it by the plastic ring and carefully place it in the
provided package (with desiccant). Store the package someplace that is clean and dry.
4. Install the new window.
a. Grasp the new window by the plastic ring and carefully place it in the window
replacement tool with the window threads facing up.
b. Rotate the window until the three notches in its outside rim line up with the ribs on
the tool's inside rim.
c. Reversing the removal procedure above, tip the tool and window just enough to place
the window over the opening in the spectrometer.
d. While maintaining light pressure against the spectrometer wall, slowly turn the tool
clockwise to ensure the window's threads are engaged properly.
NOTICE The window should turn easily at the start; if it doesn't, reverse the
direction of rotation and restart the insertion to avoid stripping the threads.
e. Continue rotating the tool clockwise until you feel the O-ring compress, plus 1/8
turn more.
