GENERAL OPERATIONS

Guidelines & Safety Precautions

• Do not place the reactor near a heat source. Avoid the presence of flammable liquids near the operating reactor.
• Do not cover the ventilation slits on the side.
• Disconnect from power if an accidental spill occurs.
• Handling chemical samples, standards, and reagents can be dangerous. Review the Safety Data Sheets and become familiar with all safety procedures before handling any chemicals.
• Reactor block heats up a few degrees higher than selected temperature as it accounts for localized heat transfer to vials.
• Reactor block temperature drops as vials are inserted into the reactor. Allow time for block temperature to reach required digestion temperature.

INSTALLING THE LABORATORY SAFETY SHIELD
HI839150 is supplied with a laboratory safety shield with weighted handles that maintains proper safety position throughout digestion procedure. Use of safety shield is strongly recommended to maintain a safe working environment.

STARTUP

1. Place the reactor on a level and stable surface.
2. Connect to power. Check back of the instrument for correct voltage and frequency.
3. Switch the instrument on. POWER LED turns on.
   All LCD segments are briefly displayed followed by initialization screen. First LCD line displays block temperature and second LCD line displays the current reaction time and program temperature, alternately.

DIGESTION TEMPERATURE PROGRAM SELECTION & TIMER CONFIGURATION
105°C (221°F) and 150°C (302°F) temperature programs are delivered with the reactor.

1. Use the  key to select program.

2. Long press key to enter timer value edit mode. Timer value starts blinking.

3. Use the keys to adjust value and the  key to confirm.

4. With program selected, press and the reactor block starts to warm up.

SAMPLE DIGESTION PROCEDURE

1. Press the key. The HEATING LE D lights up (yellow). “rUn Strt” message is displayed followed by the reactor block’s current temperature and selected program temperature.

  * When the reactor block temperature exceeds 50°C, the HOT LED (red) starts blinking.
  * During warm up (10 to 15 minutes), the HEATING LED stays on (yellow) for as long as the block temperature is within 10°C of target temperature.
  * An acoustic signal (3 short beeps) alerts users that the block temperature has reached configured (selected) temperature profile and the reactor is ready for vials to be inserted. “WAIT TO SAMPLES” (“SAMPLES” blinking) is displayed.

2. . Insert the vials into the reactor. Block temperature may decrease.

3. Press the key to start timed digestion. An acoustic signal (1 short beep) alerts users that operation is in progress. The block reactor heats up to configured temperature. Countdown timer is automatically started.

The end of the digestion time is signalled by an acoustic signal (5 short beeps) and “DONE” message is displayed.
The heating is turned off and the block begins to cool off.

Note: To end digestion before the timer countdown finishes, press the key.

WARNINGS & ERRORS

The instrument displays warning messages when erroneous conditions appear and when values are outside the expected range. The information below provides an explanation of the errors and warnings, and recommended action to be taken.

MAINTENANCE

Cleaning

1. Switch off the reactor and disconnect from power. Allow the reactor block to cool off.
2. Remove vials and wipe the instrument with a soft, damp cloth.
   Water should not reach inside the reactor block.

Replacing a spent fuse
Replace only with fuse of the specified type and current ratings.

1. Switch the reactor off and disconnect from power.

2. Turn the fuse holder counterclockwise until it disengages.

3. Retain the cap which holds the fuse, and replace the fuse in the cap with a new, appropriately rated fuse
   i.e. use “8 AT” for HI839150-01 and “5 AT” for HI839150-02 model.

4. Replace the fuse holder and rotate it clockwise.
