The COD165 thermoreactor will hold 25 round glass vials with 16 mm
external diameter. It is designed for sample preparation in determining
COD, total phosphorus, total nitrogen, total chromium and other
parameters in water and sludge analysis. The COD165 thermoreactor,
paired with the Thermo Scientific Orion COD reagents and the Thermo
Scientific Orion AQUAfast AQ4000 advanced colorimeter or Thermo
Scientific Orion AQUAfast AQ2040 colorimeter, provide the user with a
complete analytical setup for COD analysis. The Thermo Scientific Orion
AQUAfast AQ3700 colorimeter also performs COD analysis, as well as
nitrogen and phosphate digestion methods.
The COD165 thermoreactor is designed to be highly resistant to chemical
and mechanical corrosion. The heating block that holds the COD vials
allows for very good thermal homogeneity at the selected temperatures. The
temperature of the heating block is microprocessor controlled. The Pt100
temperature probe does not require any calibration, because when the
instrument is turned on, a self test is performed.
The COD165 thermoreactor is equipped with a voltage selector for either
115 V or 230 V. It is accessible on the rear panel of the instrument. Always
check the voltage setting before plugging the instrument into a power
outlet.
The COD165 thermoreactor has five preset work temperatures of
100 °C, 120 °C, 150 °C, 160 °C and 165 °C and four preset run times of
30 minutes, 60 minutes, 120 minutes or continuous time.
The heating block is equipped with over-temperature protection by a
thermostat, which turns off heating when the temperature exceeds 180 °C.
Note: The COD165 thermoreactor is delivered complete with three power
cords; one for 110 to 120 V standard US outlets, one for 220 to 240 V
European outlets and one for 230 V Chinese outlets.
General Information

Thermo Scientific Orion COD165 Thermoreactor User Guide
The instrument is equipped with a voltage selector, which allows the
connection to either 115 V or 230 V outlets.
After unpacking the unit, position it correctly on the laboratory bench.
Before connecting it to the power supply, check that the power switch is
turned to “0” and check that the data on the unit’s plate corresponds to
that supplied by the electric socket. The unit works at voltages between 90
and 260 V with a frequency of 50 or 60 Hz.
Note: The power switch means that the unit can be completely
disconnected from the power supply when it is not in use, thus reducing
energy consumption.
Use the power switch on the front of the unit to turn the unit on (turned
to “−”). When it is switched on, all the LEDs on the unit blink for few
seconds. When the LEDs are off, the unit is ready to be programmed at
different work temperatures and times.
Control Description
Power Switch The switch lights up when the instrument is turned on.
Start/Temp Key When the Start/Temp key is pressed, the work cycle is started
with the selected temperature and time values, which are
indicated by their corresponding LEDs.
To change the temperature, press the Start/Temp key and
select desired temperature. The temperature setting will scroll
down through the four temperatures and the corresponding
LED will light.
Note: It is possible to select different temperatures if the
programmed temperature has not been reached and the timer
is not started. Once timer has started this key is not operative.
If the selected temperature is lower than the actual
temperature of the heating block when the Start/Temp key is
pressed, the cycle will not start and all the LEDs will turn on
intermittently, indicating an error.
To correct this error, select a higher temperature setting
or allow the block to cool to a temp below the set point
temperature.
Time Key The timer starts when the block reaches the selected
temperature. While the timer is running, the LED will blink and
the Time key is not operative.
Temperature LED When the instrument is turned on the temperature LEDs
are not lit. Once the Start/Temp key is pressed, the selected
temperature LED will light.
All four LEDs will blink if the selected temperature is lower
than the current block temperature.
Time LED When the instrument is turned on the time LEDs are not
lit. Select the desired run time by pressing the Time key. A
blinking time LED indicates that the timer has started.

When the unit is switched on, press the Start/Temp key to start the work
cycle. The default option is set at 160 °C and 30 minutes, as shown by the
corresponding LED. To select a different temperature, press the Start/Temp
key until the corresponding LED is lit. To select a different time, press the
Time key until the corresponding LED is lit.
Note: It is possible to modify both temperature and time until the
temperature of the heating block reaches the selected temperature and the
run time starts.
When the selected temperature is reached, a beeper will sound
intermittently for 5 seconds. At this time the LED corresponding to the
selected time will start to blink, signalling that the countdown has started.
The end of the countdown will be signaled by a beeper that will sound
continuously for 5 seconds; at the same time the heating element and the
corresponding time and temperature LED will turn off. The instrument is
now ready for a new work cycle.
The instrument will register a black out or a lack of power supply as a
manual stop of the cycle. The work cycle will have to be restarted.
The COD165 thermoreactor will shut down once the timer cycle is
complete. If the power to the instrument is interrupted, the instrument will
automatically end the program that is running and a manual restart
is required.
The COD165 thermoreactor is equipped with an internal thermostat
that will not allow the temperature of the block to exceed 180 °C. If this
temperature is reached the unit will automatically shutdown. The COD165
thermoreactor continuously monitors the block of temperature and if
inconsistent or anomalous readings are observed, the instrument will go
into an alarm mode in which all eight LEDs blink and a beeper sounds.

Chapter 2 Operation
To initiate a cycle on the COD165 thermoreactor, power on the instrument
and press the Start/Temp key.
The default settings are a temperature of 165 °C and a run time of 30
minutes, which will be indicated with the temperature and time LEDs. Use
the Temp or Time key to change the temperature or time setting.
The selected temperature and time settings are shown by the temperature
and time LEDs. It is possible to change both the temperature and time if
the selected temperature has not been reached yet and the timer has not
started. Once the selected temperature has been reached, a beep will sound
intermittently for five seconds. After the beep, the LED corresponding to
the selected time will start to blink, indicating that the timer has started.
The end of the cycle will be indicated when the beeper sounds continuously
for five seconds. At the completion of the cycle, the heater is turned off and
the temperature and time LEDs turn off.
A new cycle can be run if the temperature of the heating block is not
greater than the new selected temperature. If this occurs, the instrument
will enter an alarm mode and all of the temperature LEDs will illuminate.
Running a Cycle

6Thermo Scientific Orion COD165 Thermoreactor User Guide
All the maintenance operations should be performed only after the
instrument has been disconnected from the power supply.
The COD165 thermoreactor is designed to be maintenance-free and only
occasional cleaning needs to be performed with a damp cloth and non-
flammable, non-abrasive detergent.
The heating block is equipped with two fuses connected to the socket,
located on the rear panel. If a fuse replacement is required, the power
supply should be removed and then the fuse panel can be opened with a
screwdriver. See the Electrical Schematic section for the fuse type.
Disposal of this unit should comply with all local, state, and federal
regulations.
The electronic temperature controls within the COD165 thermoreactor are
designed to provide excellent stability and eliminate temperature overruns
or oscillations. The temperature sensor does not require calibration, as a
self-calibration is performed upon power up of the instrument.
The temperature may be monitored using a standard NIST traceable
thermometer with a range of 0 to 250 °C. Place the thermometer in a hole
within the heating block and monitor the temperature.
