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.

Note: Once calibration has been performed for a given aluminum block, vial size and ambient condition, setting the Heat knob to the same set temperature with the Display Adjust knob at the same dial position for subsequent uses will reproduce the same heating performance. You may wish to mark or note the Display Adjust dial position for future reference when using this same heating application.

Instructions for Use with Remote Temperature Probe (RTP, Product No. 18820)

Using the Remote Temperature Probe (RTP) provides more accurate and responsive control of the heating function because it replaces the internal heat sensor (housed under the block reservoir) with one placed directly in the aluminum block or reaction vial. However, the RTP is not a substitute for temperature calibration to an independent thermometer.

For best results, perform temperature calibration for a given application (i.e., particular temperature setting, aluminum block and vial/sample size) with the RTP placed in the aluminum block thermometer well and a standard thermometer placed in a reaction vial in one of the aluminum block wells. Calibration performed in this configuration will provide for accurate in-vial sample heating, controlled by the RTP conveniently positioned in the thermometer well. The triple-block module allows for both the RTP and thermometer to be placed in block thermometer wells, making alternative configurations possible. Calibrate with the RTP in a vial only if that will be the configuration for use. The following instructions assume the suggested calibration configuration. Be aware that the aluminum block and in-vial sample temperatures may be different.

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 Display Adjust knob to the center position.

Connect the RTP to the Reacti-Therm Module (left side). When the Heat knob is turned on (step 4), the Temp. Probe light will illuminate to indicate that the RTP is connected and operating as the thermal sensor.

Note: The Heat knob must be in the off position when connecting or disconnecting (plugging or unplugging) the RTP.

3. Place the RTP tip into the aluminum block thermometer well and insert a thermometer (200°C range) into a reaction vial

placed in one of the block wells. For in-vial placement of the RTP, fill the vial sufficiently with mineral oil or other suitable liquid so that the probe tip is immersed at least 2.5 cm to ensure adequate thermal contact with the vial.

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.

Example: To set temperature to 100°C, turn Heat knob until the value “100” appears (flashing) in the LED display.

5. Allow 15-30 minutes for the block to approach the set temperature, at which point the LED display stops flashing the set

temperature and begins reporting (without flashing) the block temperature recorded by the RTP. The actual time required for the unit to reach a given temperature may vary depending on the block used and the ambient (room) temperature.

6. When the LED display stops flashing, monitor the displayed temperature for an additional 15 minutes to ensure that the

it has fully stabilized (i.e., that the in-vial thermometer reading remains unchanged for several minutes). Note that the thermometer reading, although stabilized, might still be different from the set temperature reported by the RTP.

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-vial 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 in-vial thermometer) and has remained unchanged for several minutes. Harmonize the reported (displayed RTP) 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 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.
