Note
On initial start-up, the purity meter
may display “...M
Ω
-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)
M
Ω
-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 “.... M
Ω
-
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.”
