2.6 Installing the Distributor (Multiple Bottle Operation)

Note: Make sure the sampler is powered off before removing or installing the distributor.

For multiple bottle sampling, a motorized arm (Distributor) is provided to automatically position the sample tube over the proper bottle. The microprocessor-controlled distributor arm can automatically locate two, four, eight, 12, or 24 discrete bottles.

To install the distributor:

1.Locate the two slots along one edge of the distributor assembly base plate (Figure 14). Slide the distributor assembly, slots first, under the shoulder screws located on the top inside surface of the controller section.

2.When fully seated, hand tighten the knurled thumbscrew to hold the distributor in place.

3.To ensure the arm has sufficient freedom of movement, hand-rotate the arm to the opposite end of the Arm Stop.

4.Install the silicone distributor tubing to the sample fitting on the top underside surface of the controller housing.

Note: Use care not to force the arm past the Arm Stop clip. The Arm Stop keeps the arm from being rotated more than 360 degrees and keeps the distributor tubing from kinking.

The distributor tubing should be installed so that the end of the tubing extends out of the nozzle end of the distributor arm no more than 1/8 in. (Figure 13). Do not let the tubing extend more than 1/8 in. past the nozzle end of the arm.
