Nanopure TOC - Analytical 2-1Thermo Scientific
Section 2 Introduction
Congratulations on your purchase of a Thermo Scientific Barnstead
Nanopure TOC - Analytical ultrapure water system. This water
purification system is designed to provide low TOC, high resistivity,
reagent grade water that exceeds ASTM Type I, ISO 3696 and CLSI-
CLRW Type I standards. It uses a four-stage deionization process
combined with a 0.2 micron filter to polish suitable feed water (distilled,
deionized, or reverse osmosis) to produce low TOC (<10 ppb) water with a
resistivity of up to 18.2 megohmcm. Water resistivity is continuously
monitored by a resistivity cell and displayed on a digital display. Actual
system TOC values, obtained by an integrated TOC analyzer, can be
concurrently displayed with the resistivity.
The electronics can be verified and calibrated utilizing a N.I.S.T. Traceable
Calibration module. See accessory ordering information.
Read the instructions carefully to ensure that you receive maximum benefit
from the Nanopure TOC - Analytical. Also, fill out and return the
enclosed warranty registration card as it will help us assure you of proper
warranty coverage.

Section 5 Installation
The Nanopure TOC - Analytical features a removable control panel
display which allows the system to be mounted almost anywhere within
the laboratory. Use the wall bracket for wall mounted systems as a template
to drill mounting holes. (The Nanopure TOC - Analytical does not
include screws and fasteners for mounting.) Refer to the “General
Specifications” section for clearance requirements.
Caution Wall composition, condition and construction as well as fastener
type must be considered when mounting this unit. The mounting surface
and fasteners selected must be capable of supporting a minimum of 150
lbs.(68 kg). Inadequate support and/or fasteners may result in damage to
mounting surface and/or equipment. If you are unsure of mounting
surface composition, condition and construction or correct fasteners,
consult your building maintenance group or contractor. s
Warning Do not locate the Nanopure TOC - Analytical directly over
equipment that requires electrical service. Routine maintenance of this unit
may involve water spillage and subsequent electrical shock hazard if
improperly located. s
Do not use in the presence of flammable materials; fire or explosion
may result. This device contains components which may ignite such
materials.
Note The outlet of a gravity feed storage reservoir must be above or at
the same level as the inlet of the Nanopure TOC - Analytical. s

Installation
Optional accessories for this unit include a float switch, low pressure
switch, N.I.S.T. Traceable Calibration Module, standard remote dispenser,
Accudispense volumetric remote dispenser, dispense overflow cutoff float
and printer. If you purchased a float switch or low pressure switch, refer to
“User Settings’ in this manual. If you purchased a standard or
Accudispense volumetric remote dispenser, refer to their respective operator
manuals for installation instructions.
1. Place the Nanopure TOC - Analytical on a bench top that is accessible
to pretreated water, electricity and an atmospherically vented drain.
Note A bracket is available that will allow you to mount the control panel
on the bench, if bench mounting is desired, order bracket AY1367X2. s
Install the Nanopure TOC - Analytical on a wall in a convenient location
that is accessible to water, an atmospherically vented drain and electricity.
Caution Wall composition, condition and construction as well as fastener
type must be considered when mounting this unit. The mounting surface
and fasteners selected must be capable of supporting a minimum of 150
lbs.(68 kg). Inadequate support and/or fasteners may result in damage to
mounting surface and/or equipment. If you are unsure of mounting surface
composition, condition and construction or correct fasteners, consult your
building maintenance group or contractor. s
Warning Do not locate the Nanopure TOC - Analytical directly over
equipment that requires electrical service. Routine maintenance of this unit
may involve water spillage and subsequent electrical shock hazard if
improperly located. s
Note The outlet of a gravity feed storage reservoir must be above or at the
same level as the inlet of the Nanopure TOC - Analytical. s
Bench Mounting
Wall Mounting

1. Locate the wall bracket packed separately from the unit.
2. Using the wall bracket as a template, locate and drill the mounting
holes in the wall. A minimum of four (customer-supplied) fasteners
will be required — two on the top and two on the bottom.
3. Attach the wall bracket to the wall using the customer-supplied
fasteners.
4. Remove the locking screws on each side of the wall bracket.
5. Pull the two locking slides on each side of the wall bracket out as far as
they will go.
6. Hang the unit on the wall bracket by sliding the mounting pins into
the wall bracket slots.
7. Push locking slides on each side of wall bracket in as far as they will go.
8. Replace the locking screws.
For your convenience, the control panel can be removed from the unit and
mounted at a convenient location within 10 ft. (3.1 m.) of the unit.
Note The removable control panel was not designed to be repeatedly
removed from the unit, therefore, you may experience difficulty when
attempting to remove it. It is therefore recommended that the control
panel be permanently mounted in a remote location or remain intact with
the unit. s
Caution Repeated removal and replacement of the control panel from the
top cover may eventually cause it to become damaged.
Note The blank protective cover on the rear side panel display connector
should remain in place when the display is not remotely located.
To remove the control panel from the unit:
1. Turn the unit OFF and disconnect it from the power supply.
2. Slide the control panel upward about 1/4” (.64 cm) to 3/8” (.95 cm) -
(just enough to clear connector on top cover), pull forward, and
remove. (The control panel fits tightly in the unit so it may be difficult
to remove.)

the protective black cover and store it for future use if the control panel
is returned to the top cover.
6. Locate the 10 ft. (3.1 m.) 25 pin M-F cable included with the unit;
attach the female end to the 25 pin connector on the back top right of
the unit, and the other end to the connector on the bottom of the
control panel.
7. Tighten the cable screws on each end to secure the cable to the unit
and control panel.
8. The control panel may now be mounted on the wall.

1. Locate the length of 3/8” O.D. tubing provided with the unit with a
quick disconnect insert on one end and a 3/8” (.95 cm) O.D. X 1/4”
(.64 cm) NPT tubing adapter on the other.
2. Install the tubing adapter onto your incoming water line. We
recommend a customer supplied shut off valve be installed in your feed
water line. Do not connect the feed water to your Nanopure TOC -
Analytical. You will connect the feedwater during the “Initial
Cleaning” procedure explained later in this manual.
Note The cartridge pack must be installed before connecting water line. s
3. If a pressure switch is to be used, see the “Installing a Float or Pressure
Switch” section for more information.
When the Nanopure TOC - Analytical flushes its membrane, the water
used is sent to drain through this connection. To install:
1. Locate the drain water tubing. This is the 1/4” (.64 cm) O.D. tubing
that is approximately 6 ft. (1.9 m.) long. The atmospheric drain fitting
is located on the lower left side of the Nanopure TOC - Analytical.
2. Route the other end of the drain water tubing to an atmospherically
vented drain and make a connection. Ensure there are no kinks in the
tubing and that it proceeds in a downward plane. Proceed to “Initial
Operation.”
Note To prevent leaking, push the tubing into the atmospheric drain
connection until it bottoms out. s
