Section 2 Installation
2.1 4700 Sampler Installation Overview
The following sections provide general
instructions for placing the sampler into
operation. In typical applications, the steps are:
1. Position the sampler. (Section 2.2)
2. Install a bottle kit. (2.3)
3. Attach the suction line. (2.4)
4. Attach a strainer. (2.5)
5. Route the suction line and strainer. (2.6)
6. Connect external instruments. (2.7)
7. Connect power. (2.8)
8. Configure and program the sampler. (2.9)
9. Lock the sampler. (2.10)
2.2 Positioning the Sampler
There are a few considerations when selecting a
site for the sampler. The foremost concern
should be personal safety.
2-1
4700 Refrigerated Sampler
The installation and use of this product may
subject you to dangerous working conditions
that can cause you serious or fatal injuries.
Take any necessary precautions before entering
the worksite. Install and operate this product in
accordance with all applicable safety and
health regulations, and local ordinances.
WAR NING
If this product is used in a manner not specified
in this manual, the protection provided by the
equipment may be impaired.
WAR NING
This product has not been approved for use in
hazardous locations as defined by the National
Electrical Code.
WAR NING
The sampler is heavy. When lifting, use a
two-person lift at the points identified in Table 1-1.
When possible, move the sampler using a
two-wheeled hand cart from the left or right side.
To prevent damage to the refrigeration system, do
not tip the sampler more than 45°.
Dangerous locations – If you must enter a
manhole, confined space, or other dangerous
location to install the suction line and strainer,
observe standard safety precautions. Refer to
2-2
Section 2 Installation
Appendix B of the Installation and Operation
guide for a discussion of safety considerations.
Support – The sampler should be installed on
a surface capable of safely supporting the
sampler, full liquid containers, and personnel.
AC Power – The mains line cord is the
disconnect device should you need to remove
power. Therefore, the electrical power outlet
should be accessible.
Environmental – The sampler is designed for
outdoor use. Refer to Table 1-2 for
environmental specifications. When possible,
avoid subjecting the sampler to chemical
attacks and direct sunlight.
Avoid submersion – Although the control
panel will resist damage (rated NEMA 4x, 6;
IP 67), the refrigerator system and bottle
compartment cannot prevent the liquid from
entering. Liquid entering the refrigeration
system might permanently damage the
sampler; liquid entering the bottle
compartment might contaminate the collected
samples. Liquid entering the electrical
compartment for the refrigeration system
might result in a short circuit and possible
shock hazard.
Liquid sample collection point – It is best to
keep the distance between the sampler pump
and the collection point as short as possible.
The shorter distance will increase pumping
efficiency and pump tubing life. Also, the pump
inlet should be located above the liquid surface.
Gravity will aid suction line rinses and allow
2-3
4700 Refrigerated Sampler
the line to drain, thereby reducing the
possibility of sample cross-contamination. Refer
to Table 1-2 for maximum suction line lengths
and suction head heights.
Security – The location may need to provide
some degree of security to prevent tampering or
vandalism.
Accessibility – The sampler must be installed
in a location where personnel can easily
exchange bottles and perform routine service.
The sampler requires about 2600 square
centimeters (925 in
2
) of floor space. Additional
space must be allowed in front of the sampler,
at its left and right sides, and above the
sampler. Do not block access to these areas.
Obstructions will make routine servicing
activities difficult or impossible.
The back of the sampler may be placed against
a wall as long as air at the bottom of the
refrigerator can flow freely to surrounding air.
Unrestricted air flow behind and around the
sampler will keep the refrigeration system
working efficiently.
Level surface – The sampler should be placed
on a level surface and the feet on the
refrigerator body should be adjusted to prevent
tipping or spills. If the sampler is not level, the
sample liquid may miss the bottle mouth.
To level the sampler, place a bubble level on the
bottle rack or locating base, then adjust the
feet. For one-bottle configurations, place the
bubble level on the side rails of the refrigerated
compartment.
2-4
Section 2 Installation
CAUTION
Do not tip the sampler on its side or back. Tipping
the sampler more than 45° might cause oil to run
into the compressor inlet, which can permanently
damage the sampler.
2.3 Installing a Bottle Kit
The 4700 sampler can hold 1, 2, 4, and 24
bottles. Each of these bottle configurations are
supplied as a kit (see Table 2-1), which is
normally ordered with the sampler or when you
desire to change the bottle configuration.

4700 Refrigerated Sampler
2.3.1 Installing the Distributor Arm and
Discharge Tube
The distributor arm ships with the sampler
installed on its mounting shaft inside the
refrigerator (Figure 2-1). It is generally 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.
Figure 2-1 Installing the distributor arm and
discharge tube
2. Pull the distributor arm downward to
remove it from the keyed shaft.
3. Thread the discharge tube through the body
of the distributor arm.
4. Insert the end of the discharge tube into the
outlet hole on the distributor arm.
2-8
Section 2 Installation
CAUTION
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.
6. Push the distributor arm up onto the keyed
shaft and secure it with the knurled nut.
7. Push the loose end of the discharge tube
onto the bulkhead fitting in the top-front
corner of the refrigerator.
8. Inspect the discharge tube:
CAUTION
An incorrectly installed discharge tube can cause
the distributor arm to fail. It can also
cross-contaminate samples. To prevent these
problems, inspect the discharge tube as described
in the following steps.
a. Manually rotate the arm to make sure
that the tube does not obstruct its
movement. If the tube obstructs arm
movement, re-route the discharge
tubing.
b. The discharge tube must slope
downward from the bulkhead fitting to
the arm throughout the range of arm
motion. Otherwise, liquid might pool in
2-9
4700 Refrigerated Sampler
the tube and cross-contaminate samples.
Note that the discharge tube has a
natural curve. Should the tube create a
low spot where liquid can pool, twist the
end of the tube connected to the
bulkhead fitting so that the natural
curve holds the tube in a downward
sloping position. Then, retest the tube at
other arm positions.
2.3.2 24 Bottles
The 24 bottle configurations use a rack to hold
and align the containers. To install the bottles
in the refrigerator using the rack:
1. Place the uncapped bottles in the rack.
2. If you are using 350 ml glass bottles,
compress the retaining ring and place it in
the center of the bottles. Release the ring
and the outward force of the ring will secure
the bottles. (The polypropylene and
®
ProPak
bottles do not use a retaining ring.)
Note
Bottles caps can be stored in the center of the bottle
rack.
3. Locate the back of the rack (arrow, Figure
2-2). This end has a notch that fits a key on
the rear wall of the refrigerator.
4. Lift and insert the back of the rack into the
refrigerated compartment.
2-10

2-11
4700 Refrigerated Sampler
Note
There are four metal guides along the sidewall of the
refrigerator, two on each side. The front two guides fit
along the left and right sides of the rack. The back two
guides run along the top of the rack to prevent the rack
from tipping forward.
5. Slide the rack along the guides. Push the
rack in until the left-side latch (inset,
Figure 2-3) secures the rack.
2.3.3 4 Bottles
The four bottle configuration uses a locating
base to hold and align the bottles. To install the
base and bottles:
1. Slide the locating base into the bottom of
the refrigerated compartment (Figure 2-4).
Note that the arrow must be pointing
toward the back of the refrigerator.
2. Insert the four uncapped bottles into the
numbered holes in the locating base.
Note
Bottle caps can be stored between the bottles.
2.3.4 2 Bottles
The two bottle configuration uses a locating
base to hold and align the bottles. To install the
base and bottles:
1. Slide the locating base into the bottom of
the refrigerated compartment (Figure 2-4).
Note that the arrow must be pointing
toward the back of the refrigerator.
2-12
Section 2 Installation
Figure 2-4 Installing the locating base
2. Insert the two uncapped bottles into the
holes numbered “1” and “2” in the locating
base.
Note
When the sampler controller is configured for two
bottles (section 3), samples will only be distributed to
bottles 1 and 2. If you place the bottles in positions 3 or
4 the liquid will miss the bottle.
Note
Bottle caps can be stored between the bottles.

If your one-bottle configuration has a 10 liter
(2.5 gallon) polyethylene, glass, or ProPak
bottle, use a locating base to hold and align the
bottle. If your one-bottle configuration has a 20
liter (5 gallon) glass or polyethylene bottle,
simply place the bottle in the center of the
refrigerator; no rack or locating base is
required.
Refer to the instructions for your bottle size.
10 liter bottle – To install the locating base
and 10 liter bottle:
1. Slide the locating base into the bottom of
the refrigerated compartment (Figure 2-4).
Note that the arrow must be pointing
toward the back of the refrigerator.
2. Insert the bottle into the hole numbered “1”
in the locating base.
Note
When the sampler controller is configured for a single
10 liter bottle (section 3), samples will only be
distributed to bottle 1. If you place the bottle in any other
position liquid will miss the bottle.
20 liter bottle – To install the 20 liter bottle:
The distributor arm should be removed to
prevent it from being an obstruction while you
replace the bottle. To remove the arm:
1. Remove the knurled nut that secures the
distributor arm.
2. Pull the distributor arm downward to
remove it from the keyed shaft.
