2.4.1 Installing the
Distributor Arm and
Discharge Tube
Figure 2-2
Installing the distributor arm (A) and discharge tube (B)
If you have selected a multi-bottle kit, first install the distributor
arm and discharge tube (Section 2.4.1), then refer to the instruc-
tions for your selected bottle configuration:
• 24 Bottle configurations – section 2.4.2
• 4 Bottle configurations – section 2.4.3
• 2 Bottle configurations – section 2.4.4
If you have selected a single (composite) bottle kit, refer to the
instructions in section 2.4.5.
For first-time use of the sampler, or if you have changed the
bottle kit, be sure to configure the software for the new bottle kit
(section 3.3.2).
The sampler is shipped with the distributor arm installed on its
mounting shaft inside the refrigerator (Figure 2-2). It is gen-
erally easier to install the discharge tube with the arm removed,
then you can reinstall the distributor arm. To do so:
1. Remove the knurled nut that secures the distributor arm.
2. Pull the distributor arm downward to remove it from the
keyed shaft.
3. Thread the discharge tube through the body of the distrib-
utor arm.
4. Insert the end of the discharge tube into the outlet hole on
the distributor arm. The end of the tubing should be flush
with, or within 3 mm (
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.
