Teledyne 4700 Pocket Manual page 25

The discharge tube should not extend below the
hole in the distributor arm. This could cause the
distributor to fail if the excess tubing catches a
bottle.
5. Pull on the loose end of the discharge tube
to remove any slack. The tube should follow
the contour of the distributor arm.
6. Push the distributor arm up onto the keyed
shaft and secure it with the knurled nut.
7. Push the loose end of the discharge tube
onto the bulkhead fitting in the top-front
corner of the refrigerator.
8. Inspect the discharge tube:
An incorrectly installed discharge tube can cause
the distributor arm to fail. It can also
cross-contaminate samples. To prevent these
problems, inspect the discharge tube as described
in the following steps.
a. Manually rotate the arm to make sure
that the tube does not obstruct its
movement. If the tube obstructs arm
movement, re-route the discharge
tubing.
b. The discharge tube must slope
downward from the bulkhead fitting to
the arm throughout the range of arm
motion. Otherwise, liquid might pool in
