Operation
W A R N I N G
Chemical exposure hazard. Obey laboratory safety procedures and wear all of
the personal protective equipment appropriate to the chemicals that are handled.
Refer to the current material safety data sheets (MSDS) for safety protocols.
Routine operation
CAUTION
Burn Hazard. Do not put a finger in an opening in the heating block. Close the
protective cover before increasing the temperature of the heating block, and
always keep the protective cover closed during operation.
English 7

CAUTION
Burn Hazard. Sample cells are hot. Wear thermal insulating material (e.g., gloves
or finger cots). Do not remove a sample cell that is greater than 80 °C. Do not put
a sample cell that is greater than 80 °C in a colorimeter.
CAUTION
Chemical Hazard. If a sample cell breaks, do not let the liquid touch skin. Use a
fume hood as necessary to remove chemical fumes.
NOTICE
To prevent sample cell and instrument damage, keep the openings in the heating
block dry. Dry the outside of sample cells fully.
NOTICE
To prevent instrument damage, immediately disconnect power if an accidental
spill occurs or a sample cell breaks, then clean the instrument. Refer to Clean the
instrument on page 9.
NOTICE
Do not cover the ventilation slits in the protective cover. The instrument and
sample cells may become too hot and decrease the accuracy of measurement.
1. Prepare the test sample cells as specified in the analysis procedure.
2. Close the sample cells with the cap.
3. Dry the outside of the sample cells fully.
4. Turn the instrument on and open the protective cover. The last
temperature program(s) selected is shown on the display.
5. If using 16 mm tubes with a heating block with 20 mm openings, put
reducing adapters in the openings.
6. Select the correct temperature program (and digestion period if
applicable) using the keys, then push OK. Refer to Stored programs
on page 8. The temperature program is selected independently
for each heating block when there are two heating blocks.
Note: To stop a program, push the key below the program two times.
7. When the heating block is at the selected temperature (two beeps
are heard), put the test sample cells in the correct heating block and
close the protective cover.
8. Push Start to start the program.
The time counts down to zero (0). Three beeps are heard and the
heater turns off when the program is completed.
Stored programs
Table 3 gives descriptions of the stored temperature programs.
Table 3 Stored programs
Program Description
COD Increases the temperature of the sample cells to 150 °C for
120 minutes. In the cooling phase, four beeps are heard when the
sample cells are at 120 °C. Remove and carefully invert the sample
cells several times, before letting them decrease in temperature in a
rack.
TOC Increases the temperature of the sample cells to 105 °C for
120 minutes. The TOC temperature program can be used for all Hach
TOC sample cell tests.
100 °C Increases the temperature of the sample cells to 100 °C for 30, 60 or
120 minutes. For example, the “100 °C, 60 minutes” temperature
program is used to:
• Digest samples using the Metals Prep Set
• Identify phosphate and chromium
• Digest heavy metals
105 °C Increases the temperature of the sample cells to 105 °C for 30, 60 or
120 minutes.
150 °C Increases the temperature of the sample cells to 150 °C for 30, 60 or
120 minutes.
165 °C Increases the temperature of the sample cells to 165 °C for 30, 60 or
120 minutes.
User programs
The instrument has three temperature programs that are configured by
the user (PRG1–PRG3).
8 English

To configure a user temperature program:
1. Select a user temperature program using the keys.
2. Push Prog to enter programming mode.
3. Select a 4-character name for the program. Push the left key to
change the character. Push the right arrow key to move the cursor to
the next position. Push OK to save the change.
4. Push or hold down the up and down arrow keys to set the
temperature (37 to 165 °C). Push OK to save the change.
5. Push or hold down the up and down arrow keys to set the time (0 to
480 minutes). Push OK to save the change.
6. Push OK to save the program.
Maintenance
W A R N I N G
Multiple hazards. Do not disassemble the instrument for maintenance or service.
If the internal components must be cleaned or repaired, contact the
manufacturer.
CAUTION
Personal injury hazard. Only qualified personnel should conduct the tasks
described in this section of the manual.
Clean the instrument
Keep the instrument clean to get continuous and accurate operation.
W A R N I N G
Fire Hazard. Do not use flammable agents to clean the instrument.
CAUTION
Burn Hazard. Do not clean the instrument when it is hot.
NOTICE
To prevent instrument damage, do not use cleaning agents such as turpentine,
acetone or similar products to clean the instrument including the display.
1. Turn the instrument off and disconnect the power cord.
2. When the instrument is cool, clean the surface of the instrument with
a soft, moist cloth and a weak soap solution. Make sure that no water
gets into the instrument.
If the liquid in a sample cell spills or a sample cell breaks:
1. Turn the instrument off and disconnect the power cord.
2. Let the temperature of the heating block(s) and sample cells
decrease until cool.
3. Remove the liquid with a pipette. Do not let the liquid touch skin.
4. Move the liquid to the correct disposal.
5. Remove broken glass using tweezers. Remove any remaining liquid
on the instrument. Do not let the liquid touch skin.
Measure the temperature of the heating block
Measure the temperature of the heating block to make sure that the
temperature shown on the display is correct.
The temperature shown on the display is the temperature in a closed
sample cell that is filled with a liquid. While the temperature of the
heating block is increasing, the temperature of the heating block, near
the heater, may be greater than the temperature shown on the display.
Tools needed:
• Sample cell (2275800)
• Glycerol (anhydrous), 5 mL
• Thermometer, stem-type, calibrated for 95 to170 °C (203 to 338 °F)
To measure the temperature of the heating block:
1. Fill a clean, empty sample cell with glycerol that is at room
temperature.
2. Put the thermometer in the sample cell until the thermometer touches
the bottom of the sample cell.
3. Make sure that the level of the glycerol is 56 mm ± 0.5 mm (2.20 in. ±
0.02 in.) from the bottom of the sample cell when the thermometer is
in the sample cell.
English 9

4. Put the sample cell in the center opening of the second row of the
heating block.
5. Select a temperature program of 150 °C for 60 minutes using the
keys, then push OK.
6. When the heating block is at the selected temperature (two beeps
are heard), the thermometer temperature should be the same as the
temperature shown on the display.
Troubleshooting
Refer to Table 4 for error messages, possible causes and corrective
actions.
