CAUTION
This product generates, uses and can radiate
radio frequency energy and thus can cause radio
communication interference. Improper installation,
or operation, may increase such interference. As
temporarily permitted by regulation, this unit has
not been tested for compliance within the limits of
Class A computing devices, pursuant to Subpart
J of Part 15, of FCC Rules, which are designed to
provide reasonable protection against such inter-
ference. Operation of this equipment in a residen-
tial area may cause interference, in which case
the user at his own expense, will be required to
take whatever measures may be required to cor-
rect the interference.

INTRODUCTION
SECTION 1
INTRODUCTION
The Rosemount Analytical Chempure Series analyz-
ers are designed for minimal maintenance and maxi-
mum reliability. The touch of a button starts the micro-
processor-controlled program, calibrates the analyz-
er, keeps it calibrated, and reports results directly –
unattended – for a month or more. Maintenance is
simplified by a modular design with quick disconnect
fittings and color coded components.
The Chempure Series includes analyzers for many
common chemical parameters, including: silica,
phosphate, nitrate, chrome, iron, chloride, cyanide,
alkalinity, and ammonia. Sample concentration is
clearly indicated on the digital display panel, and out-
put signals are provided to drive recorders, alarms, or
other external devices such as printers or computers.
This instruction manual describes installation, opera-
tion, and maintenance of the Chempure Series ana-
lyzers. The specific chemistry of your individual ana-
lyzer is discussed in the accompanying CHEMISTRY
SECTION located in the Appendix.

SECTION 4
INSTALLATION
After the analyzer has been unpacked and all parts
accounted for, install as described in the following
chapter.
4.1 MAIN CABINET MOUNTING
4.1.1 GENERAL RECOMMENDATIONS:
• Mount the cabinet on a wall or other suitable verti-
cal surface, at least 66" (168cm ) wide and 43 1/2"
(111cm ) off the floor.
• Allow two feet of clearance at the left side of the
analyzer for access to the input/output panel, and
allow for swing of main and reagent cabinet doors.
• Allow 2 feet at the right side for access to the filter
and overflow tube assembly.
• Mount cabinet level or with a slight backward tilt for
proper leak detector operation.
• Mounting surface must be able to support 200
pounds.
• If the analyzer is to be installed out of doors, it must
be suitably sheltered to maintain the following envi-
ronmental conditions: Temperature: 50°F to 90°F,
regulated ±10°F Humidity:
10 to 80%.
To mount the main cabinet, proceed as follows:
1. Drill 6 holes in wall for mounting brackets, as indi-
cated in Figure 4-1.
2. Securely attach “L” brackets to wall using suitable
hardware. (Brackets must be anchored properly to
support 200 pounds.)
3. Attach main cabinet to “L” brackets using four
3/8" x 3/4" bolts, 3/8" split ring washers, and 3/8"
hex nuts.
4.2 REAGENT CABINET MOUNTING
To mount the reagent cabinet, proceed as follows:
1. Loosen the four bolts in bottom of main cabinet,
leaving approximately 1/4" between washer and
cabinet.
2. Lift reagent cabinet and attach to main cabinet by
placing heads of bolts into the keyhole slots in top
of reagent cabinet and sliding reagent cabinet
back.
3. Tighten screws to attach reagent cabinet to main
cabinet.
4.3 WASTE TUBE INSTALLATION
To install the waste tube, proceed as follows:
1. Guide waste tubing through main cabinet into
reagent cabinet and out the side of reagent cabi-
net.
2. Secure plastic waste tube in clamp in lower right of
main cabinet. See Figure 3-1.
FIGURE 4-1 MOUNTING MAIN AND
REAGENT CABINETS

CHEMPURE MANUAL SECTION 4
INSTALLATION
4.4 OVERFLOW SAMPLER ASSEMBLY
To mount overflow sampler assembly, proceed
as follows:
1. Mount overflow sampler assembly on outer, right
side of reagent cabinet using four bolts provided.
See Figure 4-2. (If using IF-100 In-Line Filter see
instruction sheet enclosed with filter for complete
installation instructions.)
2. Place ends of the air vent tubing and overflow
waste tubing into waste pipe.
3. Connect waste pipe to drain.
4. Supply sample stream to regulating/intake valve
with 1/4" tubing (plastic or steel) as follows:
a. Loosen and remove nut and compression fitting
from bottom of regulating intake valve.
b. Slide nut and compression fitting over end of
sample stream tubing.
c. Seat end of tubing in nipple of valve and secure
by firmly tightening nut.
4.5 ELECTRICAL CONNECTIONS
Electrical connections are made to and from the analyz-
er at the input/output panel, located on the left side of
