Operation Manual
SAMPLE CELL— MAINTENANCE AND CLEANING INSTRUCTIONS
Please Note: Proper maintenance and cleaning of the TD‐107 sample cell
is a key component of consistent oil content detection. Significant build‐up of
residue, iron oxide, or other foreign material on the inner glass tube can
materially 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.
Starting parameters of TD‐107 OCM must equal the following:
a. PPM Value between 0‐5 ppm in fresh clean water
b. Cell Condition Percentage between 70%‐100% in fresh clean water
Before Starting OWS Operations
1. Place the TD‐107 Sample Cell Inlet handle to the Maintenance position (you will see an ALM
flash on the display screen).
2. Use the supplied cleaning syringe to inject 50ml of fresh clean water into the sample cell via the
Luer‐Lok® fitting.
3. On the display screen, you will see (a) Alarm, (b) PPM value, (c) Cell Temperature, (d) Cell
Condition Percentage (between 0% ‐ 100%).
4. Allow PPM value to stabilize (typically between 0‐5ppm in fresh clean water).
5. Allow the Cell Condition Percentage to stabilize (typically between 70‐100% in fresh clean water).
6. If the PPM value has stabilized between 0‐5ppm AND the Cell Condition
percentage has stabilized between 70‐100%, the unit is ready for
operation.
7. Place the sample cell valve handle into Operating position and begin OWS operations.
After Completing OWS Operations
Note: 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. Repeated failure to
fill the sample cell with clean water at the end of OWS operations could result in a
permanently fouled cell and inaccurate OCM readings.
1. Place the TD‐107 Sample Cell Inlet handle to the Maintenance position (you will see an ALM
flash on the display screen).
2. Use the supplied cleaning syringe to inject 50ml of fresh clean water into the
sample cell via the Luer‐Lok® fitting.
3. Leave the Sample Cell Inlet handle in maintenance position while the OWS is secured.
