Pressurized Line Liquid
Sampling System
For the Isco 5800 Refrigerated Sampler
Overview
The pressurized line sampling system for the Isco
5800 sampler consists of the sampler, a relay alarm box,
a 3-way actuated ball valve, an aluminum mounting
plate, and, if pressures will be in excess of 15 psi, a pres-
sure reduction valve. The system supports sampling
from pipes with pressures up to 300 psi. This is also
compatible with the 4700 Sampler.
Operation
A normal sample routine consists of the sampler
pumping first in reverse (pre-purge), then forward
(bottle fill), and reverse again (post-purge).
When the sampler runs forward, it sends a signal to
the relay alarm box (see the instructions under
Programming to activate this function). The alarm box
alerts the 3-way valve to allow pumping of the sample
liquid. During pre-purge and post-purge, the valve
causes the remaining liquid between itself and the sam-
pler to be discharged through the third port into the
user-supplied drain.
Pressures exceeding 15 psi must be reduced prior to
reaching the 3-way valve to maintain accurate sample
volumes and avoid damage to the system. Isco offers a
stainless-steel pressure reduction valve with 1/2" NPT
fittings.
Site Requirements
The discharge drain must be routed to a point at or
near zero pressure for complete purging and prevention
of cross-contamination between samples.
The Isco pressure reduction valve is not recom-
mended for sample sources containing solids, or with
viscosities higher than that of no. 2 oil. The user is
responsible for any pre-filtering required.
The Isco relay alarm box is an essential component
of this system. It is equipped with specific hardware, cir-
cuitry, and weatherproof enclosure not feasibly
duplicated in the field.
The system must be positioned near a mains outlet
that is easily accessible, so that power can be quickly
removed in the event of an emergency.
The line cord is the only disconnect device. Mains
power is applied to the system continually.
WARNING
If this equipment is used in a manner not specified
in the instructions, safety may be compromised.
Setup and Installation
Programming
When enabled, a software option causes the sampler
to delay the bottle fill and post-purge pumping steps by
10 seconds to allow the 3-way valve to fully open. This
option must be enabled for proper filling and purging
during pressurized sampling.
To enable the pump valve option:
1. Turn the sampler controller on. From the main
menu, select CONFIGURE.
2. At SELECT OPTION, arrow to OUTPUT PINS and
select.
3. Under SET OUTPUT 1, arrow to 3-WAY VALVE
CONTROL and select.
4. Continue programming output pins as needed,
and then select EXIT CONFIGURATION.

Plumbing and Positioning
Connect the drain to a point at or near zero pressure.
A 1/2" coupler is provided for connection to the sampler
and discharge line. It may be necessary to heat the
tubing in order to slip it over the coupler.
Connect the line from the pressurized source to the
3-way valve (or pressure reduction valve if used) with
the shortest possible length of tubing.
Note
A manual shut-off valve (user-supplied) is
recommended for placement between the sampling
system and the sample source for purposes of system
removal, should this become necessary.
Ensure that the sampler outlet is positioned higher
than its connection to the 3-way valve to ensure com-
plete purging.
CAUTION
Ensure that the user-supplied connecting hardware
between the liquid source and the system inlet can
safely withstand the maximum pressures of the source.
Pressure Reduction Valve
The pressure reduction valve (Figure 2) is required
for installations where pressures will exceed 15 psi. This
is a one-way valve designed to reduce liquid pressure
from up to 300 psi to a pressure adjustable between 3
and 30 psi. When used with Isco samplers, the pressure
should be adjusted for 8 to 10 psi.

Teledyne Isco is continually improving its products and reserves the right to change product
specifications, replacement parts, schematics, and instructions without notice.
The valve comes pre-adjusted from the factory. Field
adjustment is seldom required, if ever.
However, if adjustment should become necessary:
1. Loosen the lock nut located behind the pressure
dial (Figure 3).
2. Turn the adjustment bolt clockwise to increase
the valve’s pressure output, or counterclockwise
to decrease it.
3. If the pressure gauge does not read between 8
and 10 psi, repeat step 2.
Note
A sample cycle may be required for the gauge to
register a pressure reading.
4. Tighten the lock nut to secure the adjustment
bolt.
Wiring
Standard systems come pre-wired and mounted on
the aluminum plate. For assistance with other types of
Isco alarm boxes, additional alarm outputs, and systems
that are not pre-wired, contact Teledyne Isco.
Connect the signal cable from the relay alarm box to
the 16-pin connector on the back side of the sampler
(see Figure 4).
Plug the line cord into the AC electrical outlet, and
the system is ready for use.

Cleaning
To clean the system, use a mild detergent in water.
For tougher stains, use isopropyl alcohol. If the installa-
tion location permits, the system may be hosed down.
