Item Name Description
1 Control
Panel Cover
Protects the control panel
display and keypad.
2 Control
Panel
Supports user control and
programming of sampler
operation.
3 Discharge
Tube
Carries liquid to the
sample bottle. For 24, 4, 2,
and 10 liter one-bottle
configurations, the
discharge tube is routed
through the distributor
arm. For the 20 liter
one-bottle configuration
the discharge tube is
routed directly into the
bottle.
4 Distributor
Arm
Directs collected liquids to
the bottle. Movement of
the distributor is controlled
by user-specified program
settings.
5 Bottles Hold the collected
samples.
6 Bottle
Locator
Rack
Positions the bottles under
the distributor.
7 Refrigerator
Door
Protects the collected
samples inside the
refrigerated compartment.

8 Latch Secures the door. The
latch mechanism may be
locked with a
user-supplied padlock.
9Level
Adjustment
Feet
The sampler includes two
level adjustment feet at the
front of the sampler. Use
these to keep the bottle
rack or locating deck level
inside the refrigerated
compartment.
10 Liquid
Detector and
Pump
The non-wetted liquid
detector senses when the
liquid is at the pump to
determine head height
and sample volumes. The
peristaltic pump collects
sample liquid and
performs suction line
rinses.
11 Lift Points If you must lift the sampler,
it can be safely handled at
these points. Lifting must
be done by two people,
one on each side, with the
door closed and latched.

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.

4700 Refrigerated Sampler
2-2
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.
WARNING
If this product is used in a manner not specified
in this manual, the protection provided by the
equipment may be impaired.
WARNING
This product has not been approved for use in
hazardous locations as defined by the National
Electrical Code.
WARNING
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

Section 2 Installation
2-3
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

4700 Refrigerated Sampler
2-4
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 in2) 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.
