Installation
3.3.2 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.
Refer to
Figure 4 on page 16 for a diagram of required components.
Prerequisites:
• One plastic or glass bottle
• Retainer (Cat. No. 2190)
Note: Refer to Figure 2 on page 9 to make sure that the correct sample
bottle is used with the correct sampler base and retainer.
Installation procedure:
1. Clean the sample bottle as described in section 3.3.1 .
2. If using a 2.5-gallon bottle with the standard base, place a
container support (Cat. No. 1502) in the sampler base.
3. Place the sample bottle in the center of the base.
4. Fill the sampler base with ice after the bottle is in place to
preserve samples.
Note: The time that it takes the ice to melt varies with the amount of
ice used, the external temperature and sample temperature.
5. Place the midsection over the base, making sure that the full
bottle shut-off is inside the neck of the bottle.
6. Program the sampler and install in the field.
3.3.2.1 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:

Installation procedure:
1. Slide the slot in the full bottle shut-off base plate under the
retainer pin inside the center section ( Figure 7 ). Make sure that
the tube and cable exit through the openings in the full bottle
shut-off assembly.
2. Position the thumbscrew over the threaded hole and hand
tighten to hold the device in place.
3. Connect the cable on the full bottle shut-off to the bottom of the
controller ( Figure 7 ). Turn to tighten.

inside tube fitting ( Figure 7 ).
