Caution
Biological sample hazard. Follow safe handling protocols during contact with
sample bottles and sampler components. Disconnect the sampler from power to
disable the pump before handling.
The sampler is set up at the factory with a single bottle or multiple bottle configuration. To
change the bottle configuration:
Determine the components that are required for the selected configuration.
Install the full bottle shut-off device or distributor assembly.
4.4.1 Clean the sample bottles
Clean the sample bottles and caps using a brush and water with a mild detergent before
setting up the sampler. Rinse the containers with fresh water followed by a distilled water
rinse. Glass bottles may also be autoclaved.
4.4.2 Single bottle installation
Use a single bottle when one composite sample is needed. A full bottle shut-off signals
the controller when to stop sample collection. Figure 6 on page 24 shows a diagram of
required components.
Prerequisites:
• One plastic or glass bottle
• Tubing extension (if using 2.5 gallon bottles)
Installation procedure:
1. Clean the sample bottle as described in section
2. Place the sample bottle in the center of the refrigerator. Bottle position numbers are
molded on the tray.
3. Install the full bottle shut-off (Figure 20 on page 41).
4. Program the sampler.
4.4.2.1 Full bottle shut-off installation
The full bottle shut-off is typically installed at the factory and signals the controller when
the bottle is full. Complete the following steps to replace or install a new full bottle
shut-off.
Prerequisites:
• Full bottle shut-off device
• Tubing support and tubing
Installation procedure:
1. Install the rubber grommet into the center hole provided in the cap of the composite
bottle.
2. Slide the full bottle shut-off, float first, into the bottle through the center of the
grommet.
3. Connect the cable on the full bottle shut-off to the bottom of the controller (Figure 20
on page 41). Turn to tighten. Attach cable assembly to twist clip.
