Start-Up Sample Cell Maintenance And Cleaning - Turner Designs TD-107 5.0 Operation Manual

5.3 Start-Up Sample Cell
Maintenance and Cleaning
Proper maintenance and cleaning of the
5.0
TD-107 sample cell is a key component of
consistent oil content monitoring. Significant
build-up of residue, iron oxide, or other
foreign material on the inner sample cell
wall can significantly affect the detection of
the fluorescent properties of the oil.
Consistently following these simple cleaning
and maintenance procedures will ensure
accurate and reliable operation from the
monitor.
5.3.1 Pre-OWS Operation Check
Prior to starting the OWS, perform the
following steps:
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
3. On the LCD, you will see the ppm value
and Cell Condition Percentage
displayed on the right side.
4. Allow the ppm value to stabilize
between 0–5 ppm in fresh clean water.
5. Allow the Cell Condition Percentage to
stabilize between 70–100% in fresh
clean water.
6. If the ppm value has stabilized between
0–5 ppm AND the Cell Condition
Percentage has stabilized between 70–
100 %, the unit is ready for operation. If
not, perform the cleaning steps outlined
in Section 5.3.2.
7. 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.
5.3.2 Sample Cell Cleaning
If the 'ppm value' OR the 'Cell Condition
Percentage' is out of starting parameters,
the sample cell requires chemical and
mechanical cleaning prior to operation

5.3.2.1 Sample Cell Cleaning with
Detergent
1. Close the TD-107 inlet valve handle.
MAINT MODE will be displayed on the
left side of the LCD.
2. Fill the supplied syringe with 60 mL of
the provided cleaning solution (NAG
Part Number 2522).
If the recommended cleaning
solution is not available, substitute
mild detergent diluted with 50%
fresh water.
3. Inject the cleaning fluid into the sample
cell via the Luer-Lok® fitting.
4. Unscrew the clean-out port fitting cap
(located at the top of the sample block).
5. Insert the provided flow cell brush (NAG
Part Number 2506) and aggressively
scrub the inner wall of the sample cell
for approximately one (1) minute.
Use of a flow cell brush other than
part number NAG2506 could
potentially scratch the inner wall of
the sample cell and cause the OCM to
malfunction.
6. 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.
7. Use the provided syringe labeled
"Distilled Water" to inject 120 mL (two
syringes full) of clean fresh water into
the sample cell.
8. Allow the ppm value and the Cell
Condition Percentage to stabilize.
9. 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.
