Connecting the nitrogen exhaust lineB-21
3. Connect one end of the tubing to the exhaust port on the rear panel.
Connect the other end to one of two ports on the exhaust trap bottle.
4. Cut a second length of 10-mm tubing long enough to connect the exhaust
trap bottle to the exhaust vent.
5. Insert one end of the tubing into the remaining port on the exhaust trap
bottle. Route the other end to the exhaust vent.
6. Use snoop (or equivalent) leak detector liquid to ensure that there are no
leaks at the instrument exhaust and laboratory exhaust system line
connections.
Caution: To avoid gas leaks, use the sharp knife to cut the PTFE
tubing squarely (that is, perpendicular to its horizontal axis).
Warning: To confirm the integrity of the source exhaust
system, the following leak test must be performed.
Caution: To avoid damage to the instrument, snoop (or its
equivalent) leak detector liquid must be used only for the
purpose described in the following step. It must not be used on
any other part of the instrument.
