TD-1000C Oil In Water Monitor 

Operation Manual 

PN 101687 

REV G

6  PREVENTIVE MAINTENANCE

Once the monitor is installed, started-up, and calibrated, the initial settings should not require change.  
Any start-up or shutdown must be made using the TD1000C™ Main Power Switch (see 

Figure 1

).

System Values are retained in battery back-up memories for up to five years.  However, the Start-Up 

procedure should be followed to ensure fluorometer calibration and control settings are correct if the 

monitor has been disconnected for any length of time.

This monitor has been assembled with a new desiccant plug to ensure the area surrounding the flow 

cell is free of any moisture.  As this plug absorbs moisture, it will change from a light blue to light pink at 
the saturation point and should be replaced promptly and at one year intervals.  The monitor can remain 
in operation during this replacement.  Readings should be monitored during this replacement time as 
small variances might occur.  Refer to 

Appendix H

 for replacement plugs.

A Quick Reference Guide is installed on the left face of the TD1000C™.  This guide details all 
necessary parameter access details for both calibration and diagnostic needs.

The following preventive maintenance should be performed to ensure optimum monitor operation and 
maximum life.

1. 

Perform an initial check of the fluorescence calibration two weeks after installation using the 

provided Calibration Solution.  If the calibration is stable after two weeks, Turner Designs 
Hydrocarbon Instruments recommends checking at 4 week intervals.

2. 

The flow cell should be cleaned periodically.  The cell calibration % as shown on the HOME 

screen should be used as a primary reference in determining a cleaning schedule.

3.  The desiccant plug should be replaced upon turning pink or annually if no color change is 

noted.

6.1  RE-CALIBRATION

Re-calibration is recommended every 3 months, however, the actual re-calibration schedule will be 

site specific.  The TD1000C™ calibration solution available through Turner Designs Hydrocarbon 

Instruments is equivalent to 11.5 ppm of Number 6 Fuel Oil in water.  The solution value is 11.5 and the 
part number is 101666.

6.2  CLEANING THE FLOW CELL

Flow cell cleaning frequency is dependent on the quality of the water sample being monitored and 

the flow rate through the flow cell.  The flow cell is unlikely to clog, but occasionally (though rarely) 

residue can build up on the inner quartz tube walls, especially where oily water is involved.  A fouled or 

discolored flow cell can result in low or erratic readings.  For routine cleaning, follow 

Steps 1

 and 

2

 in 

Section 5.1

.  Be sure to open the flow cell shut-off valve when cleaning is completed.

Never clean the flow cell with, or expose it to, partially chlorinated solvents or caustic solutions. 

For cleaning the flow cell with a brush, perform the following steps.

1.  Turn off main power switch

.

2. 

Close the flow cell inlet valve. The valve is closed when the yellow valve handle is oriented 

horizontally.  Open the flow-cell outlet valve to the drain position.  The valve is correctly
