TD-107 Oil Content Monitor
Operation Manual
10. Open the TD-107 inlet valve. Ensure
MAINT MODE is no longer displayed
on the LCD. The instrument is now
ready to begin OWS operations.
11. If the ppm value OR Cell Condition
Percentage is still out of starting
parameters, repeat the detergent
cleaning procedure.
12. If starting parameters are still not
attained after two detergent cleanings,
proceed to Section 5.3.2.2 and perform
cleaning with acid.
5.3.2.2 Sample Cell Cleaning with Acid
1. Close the TD-107 inlet valve handle.
MAINT MODE will be displayed on the
left side of the LCD.
2. Unscrew the clean-out port fitting cap
(located at the top of the sample block).
3. Dip the provided flow cell cleaning brush
(NAG Part Number 2506) in 50% diluted
6N Hydrochloric Acid. If 6N HCL is
unavailable, muriatic acid or citric acid is
an acceptable substitute.
4. ®Insert the brush into the clean-out port
and aggressively scrub the inner wall of
the flow cell for approximately one (1)
minute.
Use of a sample cell brush other
than part number NAG2506 could
potentially scratch the inner wall of
the sample cell and cause the OCM to
malfunction.
5. Remove the brush and screw the cap
back onto the top of the clean-out port
fitting.
Hand-tighten + ¼ turn to secure the
clean-out port fitting cap. Do not
over-tighten or use pliers or
wrenches on the cap.
6. Use the provided syringe labeled
"Distilled Water" to inject 120 mL (two
syringes full) of clean fresh water into
the sample cell.
7. Allow the ppm value and the Cell
Condition Percentage to stabilize.
8. If the ppm value has stabilized between
0–5 ppm AND the Cell Condition
percentage has stabilized between 70–
100 %, the instrument is ready for
operation.
9. Open the TD-107 inlet valve. Ensure
MAINT MODE is no longer displayed on
the LCD. The instrument is now ready to
begin OWS operations.
10. If the ppm value OR Cell Condition
Percentage is still out of starting
parameters, repeat the acid cleaning
procedure.
5.4 Shut-Down Sample Cell
Maintenance and Cleaning
After Completing OWS operations:
It is important to fill the TD-107
Sample Cell with fresh clean water at
the end of every OWS operation. A cell
which is left filled with either dry air or dirty
sample water can permanently foul the
sample cell. Fill the sample cell with clean
water at the end of OWS operations in order
to maintain proper operation of the unit.
1. Close the TD-107 inlet valve handle.
MAINT MODE will be displayed on the
left side of the LCD.
2. Use the supplied syringe to inject 60 mL
of fresh clean water into the sample cell
via the Luer-Lok® fitting. Leave the TD-
107 inlet valve handle closed while the
OWS is secured.

6.0 CALIBRATION CHECK

6.1 Calibration Check Procedure

Refer to Appendix K: General
Arrangement Drawings for locations of
items. A diagram of display screens is
located in Appendix E.
Perform the following steps to check the
fluorescence calibration:
1. Close the inlet valve. The instrument will
now be in Maintenance Mode. A
Maintenance event will be recorded by
the Datalogger. Confirm
