Installation
D A N G E R
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Confined space precautions
D A N G E R
Explosion hazard. Training in pre-entry testing, ventilation, entry procedures, evacuation/rescue
procedures and safety work practices is necessary before entering confined spaces.
The information that follows is supplied to help users understand the dangers and risks that are
associated with entry into confined spaces.
On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became
law. This standard directly affects more than 250,000 industrial sites in the United States and was
created to protect the health and safety of workers in confined spaces.
Definition of a confined space:
A confined space is any location or enclosure that has (or has the immediate potential for) one or
more of the following conditions:
• An atmosphere with an oxygen concentration that is less than 19.5% or more than 23.5% and/or a
hydrogen sulfide (H2S) concentration that is more than 10 ppm.
• An atmosphere that can be flammable or explosive due to gases, vapors, mists, dusts or fibers.
• Toxic materials which upon contact or inhalation can cause injury, impairment of health or death.
Confined spaces are not designed for human occupancy. Confined spaces have a restricted entry
and contain known or potential hazards. Examples of confined spaces include manholes, stacks,
pipes, vats, switch vaults and other similar locations.
Standard safety procedures must always be obeyed before entry into confined spaces and/or
locations where hazardous gases, vapors, mists, dusts or fibers can be present. Before entry into a
confined space, find and read all procedures that are related to confined space entry.
Mechanical installation
Site installation guidelines
D A N G E R
Explosion hazard. The instrument is not approved for installation in hazardous locations.
Refer to the guidelines that follow for the site location evaluation.
• Obey all the safety precautions if the sampler is installed in a confined space. Refer to Confined
space precautions on page 8.
• Make sure that the temperature at the location is in the specification range. Refer to Specifications
on page 3.
• Install the sampler on a level surface or hang the sampler with the suspension harness, the
support bracket or the spanner bar. Refer to Install the sampler in a manhole on page 9 and to
the applicable installation documentation.
• As near the sample source as possible to decrease analysis delay. Refer to Plumb the sampler
on page 11.
• For limitations on transport velocity and maximum vertical lift, refer to Specifications on page 3.

English
Install the sampler in a manhole
Install the sampler above the sample water in a manhole. Install the sampler with a spanner bar or a
support bracket. Install the spanner bar inside the manhole. The spanner bar is supported by
pressure against the walls. The support bracket has the same width as the manhole cover. Install the
support bracket directly below the cover for support. Refer to Replacement parts and accessories
on page 42. Refer to the documentation supplied with the accessories to install the sampler.
Install the distributor or full-bottle shutoff (optional)
The distributor or full-bottle shutoff assembly is typically installed at the factory. Refer to the
distributor or full-bottle shutoff documentation for installation.
Prepare the sampler
Clean the sample bottles
Clean the sample bottles and caps with a brush, water and a mild detergent. Flush the containers
with fresh water followed by a distilled water rinse.
Install a single bottle
Use a single bottle to collect one composite sample. When the bottle is full, the full bottle shut-off
stops the sample program.
1. Clean the sample bottles. Refer to Clean the sample bottles on page 9.
2. Install the sample bottle as shown in Figure 3.

Install the first bottle for multiple sample collections
Use multiple bottles to collect samples into separate bottles or into more than one bottle. The
distributor moves the sample tube above each bottle. Install the bottles in the sampler base as shown
in Figure 4. Install the first sample bottle (number 1) below the label in the sampler base. Install the
remaining bottles in increasing numbers in the direction shown by the label. Refer to Figure 5
on page 11 for a diagram of necessary components.

Install multiple bottles
When multiple bottles are installed, a distributor arm moves the sample tube over each bottle.
Sample collection automatically stops when the specified number of samples have been collected.
1. Clean the sample bottles. Refer to Clean the sample bottles on page 9.
2. Install the first sample bottle (number 1) below the label in the sampler base. Refer to Install the
first bottle for multiple sample collections on page 9.
3. Assemble the sample bottles as shown in Figure 5. For eight or more bottles, make sure that the
first bottle goes next to the bottle one indicator in the clockwise direction.
4. Put the bottle assembly in the sampler. For eight or more bottles, align the wires in the slots in the
bottom tray.

Plumb the sampler
Install the strainer in the middle of the sample stream (not near the surface or the bottom) to make
sure that a representative sample is collected. Refer to Figure 6. Refer to Figure 7 for the intake tube
installation.
1. Connect the tubing to the sampler as shown in Figure 7.
Note: Use connection kit 2186 if Teflon-lined tubing is used.
2. Install the intake tube and strainer in the main stream of the sample source where the water is
turbulent and well-mixed.
• Make the intake tube as short as possible.
• Keep the intake tube at a maximum vertical slope so that the tube drains completely between
samples.
Note: If a vertical slope is not possible or if the tube is pressurized, disable the liquid sensor. Calibrate the
sample volume manually. Refer to Calibrate the sample volume manually on page 28.
• Make sure that the intake tube is not pinched.
