Two pieces of tubing are provided. If you are using the device with an external filter, connect the
gas source to the filter and then connect the filter to the back of the unit.
Make certain that no tube damage or inappropriate installation could allow a gas leak in labora-
tory.
To remove the gas inlet tube (if necessary); refer to Fig 5.9.

simple manual pressure on the push sleeve and with-
draw the tube from the fitting.
