5.4 Replace the distributor arm tube
The distributor arm moves over each bottle during multiple bottle sampling. Replace the tube in the
distributor arm when the tube is worn. Make sure that the correct tube is used for the correct
distributor and distributor arm.
Note: The distributor tubing is not the same as the pump tubing. The pump tubing installed in the distributor
assembly can damage the distributor. Also, samples can be missed because the distributor arm cannot move
easily.
1. Remove the tube from the distributor arm and from the ceiling of the sampler cabinet.
2. Insert the new tube into the distributor arm. Extend the tube past the end of the distributor arm
4.8 mm (3/16 in.) or 19 mm (3/4 in.) as shown in item 1 of Figure 15.
3. Insert the other end of the tube into the fitting on the ceiling of the sampler cabinet.
4. Complete the diagnostic test for the distributor to make sure that the operation is correct.
