or operating this instrument. Pay particular attention to all
danger and caution statements. Failure to do so could result
in serious injury to the operator or damage to the equipment.
To ensure the protection provided by this equipment is not
impaired, do not use or install this equipment in any
manner other than that which is specified in this manual.
Use of Hazard Information
If multiple hazards exist, this manual will use the signal
word (Danger, Caution, Note) corresponding to the
greatest hazard.
DANGER
Indicates a potentially or imminently hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that may
result in minor or moderate injury.
NOTE
Information that requires special emphasis.
Precautionary Labels
Read all labels and tags attached to the instrument.
Personal injury or damage to the instrument could occur if
not observed.
This symbol, if noted on the instrument, references
the instruction manual for operational and/or safety
information.
Hot Surfaces. Touching the reactor block surfaces and
vials while hot can cause serious burns.
Protective Earth Ground. This product requires a
protective earth connection. If not provided with a
plug on a cord, connect positive earth to this terminal
(U.S. cord set provides ground).

Safety Precautions
Safety Equipment
Use protective clothing when operating the reactor,
including goggles or face mask, and gloves.
Reagent Spills
Clean up spilled reagents immediately. If reagent contacts
skin, rinse the affected area thoroughly with water. Avoid
breathing released vapors. Read the Material Safety Data
Sheets (MSDS) supplied with each reagent for complete
chemical information.
Fire Hazard
Avoid the presence of flammable liquids near the operating
reactor. A fire hazard could be created.
Power Cord
A power cord suitable for 115 V ac line voltage is supplied
with the DRB
200.
DANGER:
Do not allow the power cord to pass under the instrument.

Section 1 Introduction
The DRB 200 is supplied as two models, with either one or
two heating blocks (
solutions in round vials of various sizes at 37–165 °C for a
period of 0–480 minutes. The small, 16 mm diameter
openings on the heating block are suitable for Hach COD,
Unicell, TOC, and Test N’ Tube tests. The larger, 20 mm
diameter openings are intended for sample preparation
reaction vessels, using the Metals Prep Set.
The DRB 200 has 6 stored and 3 programmable
temperature programs.

Section 3 Maintenance
There are no scheduled maintenance requirements for the
instrument. To ensure reliable and precise operation, it
must be kept clean.
3.1 Cleaning the Instrument
DANGER
Strong acids and
bases can cause
burns.
1. Switch off the instrument, unplug the power cord and
allow the instrument to cool.
2. Wipe the instrument with a soft, damp cloth. Make
sure no water penetrates into the instrument.
If a vial overflows or breaks, or a small amount of liquid is
spilled, proceed as follows:
1. Switch off the instrument, unplug the power cord and
allow the instrument to cool.
2. Draw off the liquid with a pipette, avoiding any
contact with the skin.
3. Transfer liquid residues to a proper disposal.
4. Remove broken glass with tweezers and wipe out any
remaining liquid, avoiding any contact with the skin.
3.2 Instrument Test
The temperature shown in the display corresponds to the
temperature in a closed HACH vial filled with an aqueous
medium. During the heating phase, the real block
temperature in the vicinity of the heater may be higher
than the temperature shown on the display.
An empty Hach vial, glycerol (approximately 5 mL), and a
calibration stem-type thermometer (95–155 °C) are needed
to check the block temperature.
21
Maintenance
1. Fill a clean, empty vial with glycerol at room
temperature, and insert the thermometer until it
touches the bottom of the vial.
2. When the thermometer is in the vial, the level of the
glycerol must be 51 mm ± 0.5 mm from the bottom.
3. Insert the vial in the center opening of the second row
of the test block.
4. Start the temperature program for 150 °C, 60 minutes
(or the COD program) for this block.
5. When the heating phase is complete, the thermometer
temperature should be the same as the temperature
shown on the display.
3.3 Changing the Protective Covers
1. Open the protective cover approximately 45°. Hold the
inside of the external hinge with your thumb.
2. Press your thumb against the inside of the cover.
Carefully lift each side of the cover out of its mounting.
3. Fit a new protective cover by following steps 1-2 in
reverse order.
