Unpack and Set Up Module
1.
Before opening the carton, examine it for signs of damage. Then open the carton without damaging it, and carefully
remove and inspect the Reacti-Therm Module and other contents. Call the delivery carrier and immediately file a claim if
shipping damage is observed. Do not discard packaging material.
2.
Check to ensure that the package includes the appropriate cord set for electric outlets in your country. (Your package
may include two cord sets, as all modules ship with a U.S. cord set for 120V outlets regardless of target country.) If the
correct cord set was not included, contact Technical Support.
3.
Verify and/or set Voltage Selection Switch for your local input voltage (110-120V or 220-240V). The Voltage Selection
Switch is located at the rear of the unit, opposite the power cord. The factory setting is "115 V" for U.S.A. and other
countries with 110-120 voltage. Move the switch to the "230V" position for countries with 220-240 voltage. The module
is equipped with a fuse set that is compatible for use with both 120V or 240V sources of electricity (see Table 1).
4.
Select an appropriate location for module operation (see Table 1 on page 1 and Warnings on page 2). For optimal
performance (i.e., temperature stability and uniformity), place the module in a thermally stable environment free of
erratic drafts and other heating devices. To facilitate even and efficient heating, make sure the module and blocks are
free of debris or contamination.
5.
Set Heat knob to the off position (turn all the way counter-clockwise). Set the Temperature Display Adjustment knob to
the center position.
6.
Plug the power cord into a suitable, grounded outlet (see Table 1 on page 1 and Warnings on page 2). The module is
powered whenever it is connected by the cord to a power supply. The unit does not have an on/off power switch.
Instructions for Use with Standard Thermometer
1.
Place clean Reacti-Block Aluminum Block(s) into the module reservoir.
Note:
The triple-block reservoir space of the
Reacti-Therm III Module must be filled with three aluminum blocks to obtain acceptable heating performance.
2.
Set Heat knob to the off position (turn all the way counter-clockwise). Set the Temperature Display Adjustment knob
(Display Adjust knob) to the center position.
3.
Place a thermometer (200°C range; Product No. 18915) into the aluminum block thermometer well.
4.
Turn the Heat knob clockwise to set the desired target block temperature (°C), as indicated in the LED display above the
Heat knob. The displayed value will continue to flash (blink) until the block temperature approaches the set temperature.
(The Temp. Probe indicator light remains off unless the Remote Temperature Probe, Product No. 18820, is being used.)
Example:
To set temperature to 100°C, turn Heat knob until the value “100” appears (flashing) in the LED display.
5.
Allow 30-60 minutes for the block to approach the set temperature, at which point the LED display stops flashing.
(Flashing stops when the unit senses that the block is within 5°C of the set temperature.) The actual time required for the
unit to reach a given temperature will vary with the block used and the ambient (room) temperature.
6.
When the LED display stops flashing, monitor the in-block thermometer for an additional 15 minutes to ensure that the
temperature has fully stabilized (i.e., that the thermometer reading remains unchanged for several minutes). Note that the
thermometer reading, although stabilized, might still be different from the set temperature.
7.
Once the block has stabilized at a given temperature, turn the Display Adjust knob until the LED display value matches
the block temperature indicated by the in-block thermometer.
Example:
Suppose the Heat knob had been set to 100°C (step 4) as indicated by the LED display. After 30 minutes, the
block temperature measures 98°C (as indicated by the thermometer) and has remained unchanged for several minutes.
Harmonize the reported (display) value to the actual (thermometer) temperature by turning the Display Adjust knob until
the LED display value equals 98°C.
8.
If the Display Adjust knob was used in step 7, re-position the Heat knob to the original target temperature.
Example:
Having changed the Display Adjust knob until the LED display value equals 98°C, now turn the Heat knob so
that the set temperature (LED display) equals 100°C.
9.
After several minutes, the block will stabilize to the desired temperature.
Note:
An inert atmosphere can be maintained over samples by using the Reacti-Vap™ Evaporator manifold system,
which provides a flow of an inert gas over samples.
