GENERAL DESCRIPTION The HI 839800 thermo-reactor is constructed of durable materials with a vial capacity to perform up to 25 digestions simultaneously. The reactor is equipped with 2 predefined temperature programs (dedicated temperature settings for COD and total phosphorous reactions at 150°C, and also 105°C for total nitrogen digestion). In addition, HI 839800 features LED indicators for visual indication of power on (POWER), heating in progress (HEATING) and hot surface warning (HOT).
HEALTH & SAFETY Before unpacking, setting up or using this reactor it is important to carefully read this manual. Pay particular attention to all warnings, cautions and notes. Failure to do so could result in serious injury to the operator or damage to the equipment.
FUNCTIONAL DESCRIPTION REACTOR DESCRIPTION Heater block: can hold up to 25 vials. POWER LED indicator: lights (green) when the power switch on the back of the reactor is set in the ON position. HOT surface indicator: flashes (red) if the block temperature is above 50°C. HEATING LED indicator: lights (yellow) only when the heater is ON.
OPERATING MODES • Idle mode: the default mode. While in this mode the meter measures and displays the heater block tempe- rature, an IDLE message, the target temperature and the reaction time. • Heating mode: activated by the START key. First, the reactor will heat to the desired temperature. When the temperature is reached and it is stable, a beep signals the user that the vials can be inserted into the heater block.
TEMPERATURE SELECTION The reactor has 2 predefined temperature profiles: • 105 °C (221 °F) • 150 °C (302 °F) To choose from the available profiles: • At start up, the display briefly illuminates all message segments then displays the heater block temperature. The current settings are displayed (reaction time and temperature) on the second line.
DIGESTION PROCEDURE • Turn the reactor on using the power switch located on the rear panel. The green POWER LED will be illuminated. • The display briefly illuminates all message segments and then displays the heater block temperature. • Select the temperature according to the specific digestion procedure. •...

• During operation, the block temperature will be slightly different for an empty block or one full of vials. If cold tubes are placed in the block, the temperature will decrease several degrees and a few minutes will be required to recover as the tubes warm. •...
MAINTENANCE The reactor should be kept clean and any reagent spills should be wiped up immediately. Do not touch the heater block unless you are certain it has cooled. If some reagent accidentally spills into the heater block, disconnect power and allow the reactor to cool; then remove all tubes and clean the block.
If the repair is not covered by the warranty, you will be notified of the charges incurred. If the instrument is to be returned to Hanna Instruments, first obtain a Returned Goods Authorization Number from the Customer Service Department and then send it with shipment costs prepaid. When shipping any instrument, make sure it is properly packaged for complete protection.
