SAFETY INFORMATION

Congratulations on your purchase of a Barnstead|
Thermolyne NANOpure DIamond TOC - UV ultrapure
water system. This water purification system is designed
to provide low TOC, high resistivity, reagent grade water
that exceeds ASTM Type I, CAP and NCCLS Type I stan-
dards. It uses a four-stage deionization process combined
with a UV lamp, and a 0.2 micron filter to polish suitable
feed water (distilled, deionized, or reverse osmosis) to
produce low TOC (<2.0 ppb) water with a resistivity of up
to 18.2 megohm-cm. Water resistivity is continuously
monitored by a resistivity cell and displayed on a digital
display. Actual system TOC values, obtained by an inte-
grated TOC analyzer, can be concurrently displayed with
the resistivity.
The resistivity electronics can be verified and calibrated
utilizing a N.I.S.T. Traceable Calibration module. See
accessory ordering information.
Please read the instructions carefully to ensure that you
receive maximum benefit from the NANOpure DIamond
TOC - UV. Also, please fill out and return the enclosed
warranty registration card as it will help us assure you of

4. Disconnect feed water supply at the quick-dis-
connect inlet valve on left side of unit.
5. Press the UP or DOWN arrow to select (YES)
and then press ENTER. Display will now read,
“Injected Sanitant (NO).”
6. Open front (left side door) to expose cartridge
pack. Remove solution syringe from wrapper.
7. Remove luer cap on system injection port,
located on the right side of the cartridge pack
manifold by turning counterclockwise.
8. Remove syringe luer cap and attach syringe to
the system luer fitting.
9. Slowly inject solution into system and remove
syringe. Avoid injecting air into the system.
10. Replace luer cap on injection port and close
door.
INITIAL OPERATION
Note
After sanitization is complete, the sani-
tization timer will automatically be
reset for approximately six months.

11. Press the UP or DOWN arrow to select (YES)
and then press ENTER. Display will now read,
“Reconnected Water (NO).”
12. Attach feed water supply removed in step 4.
13. Press the UP or DOWN arrow to select (YES)
and press ENTER. Display will now read, “Unit
Sanitizing.”
14. Unit may now be left unattended until display
reads, “Sanitization Complete: Press ENTER.”
15. After sanitization is complete the unit will return
to the (Idle) mode.
16. Press the START/STOP switch to return the unit
to the normal recirculation mode.
17. Remove the new 0.2 micron filter and bell
assembly from the bag and insert it into the dis-
penser arm manifold. Gently turn it clockwise
until it is fully seated.
18. Remove the protective cap from the filter bell.
Turn the dispense knob to the left or right and
flush 1-2 liters of water through the 0.2 micron
filter. The product water is now ready for use.
(See Normal Operation.)
INITIAL OPERATION
Note
For more demanding applications
where low TOC water is required, a
rinse of 15-20 liters through the car-
tridges and 0.2 micron filter may be
necessary.

Note
On initial start-up, the purity meter
may display “...MΩ-cm or uS/cm.”This
is caused by air in the cell and should
change to a resistivity reading almost
immediately. If the dots do not change
to a value after one minute, refer to
the “Troubleshooting”section of this
manual.
Note
Do not turn off the NANOpure
DIamond TOC - UV during non-work
hours. Doing so will allow bacterial
growth and other contamination of the
water in the system. As a result, the
system will require a rinse-up period at
the beginning of the work day to
achieve high quality product water. We
recommend using the Standby Mode.
1. Turn the system power ON by depressing the
main power switch to the “I”position.
2 The system greeting display indicates the type
of unit you own. This greeting is “UV TOC.”
3. The system electronics will initialize and check
its calibration. (All units have been factory cali-
brated.) If calibration is OK the display will show
“Calibration (passed).”The display will next read
“Meter Self Test (in progress) Self Test.
(passed).”Next, the display will read “10 (±0.2)
MΩ-cm.”This is a reading of the calibration ref-
erence value. Finally, the display will show
“TOC initialization,”“TOC: (In progress).”(Note:
The TOC initialization phase may take up to 45
seconds.)
4. From an (Idle) display, press the START/STOP
switch on the control panel to enter the normal
recirculating mode. The unit’s pump will begin to
run.
5. The display will then begin reading resistivity of
the product water. Initially it will read “.... MΩ-
cm”until the air is bled from the system.
6. If the TOC analyzer has been chosen (See “Use
TOC analyzer”), the display will begin showing
TOC values of the product water. Initially it will
read “TOC=...ppb”until valid data is available
(which may take up to 4 minutes after starting).
7. Allow the water’s resistivity to rise to the desired
purity before drawing off water.
8. The system should be left on or in standby dur-
ing the work day. (See “Use of Standby Mode.”)
Normal Operation
Note
From the normal recirculating mode
when the display is showing purity,
press ENTER to show the current tem-
perature. The temperature will display
for about 5 seconds before returning
to the normal recirculating mode.
Note
Press any switch except ENTER to
stop dispensing. Display will read,
“Auto Dispense Interrupted by User.”
