❚ Safety Warnings
Before putting the analyzer into operation, you should become acquainted with all
precautions and regulations concerning the handling of the analyzers electrical and
mechanical components in order to rule out any potentially hazardous situations to
yourself and your colleagues.
All safety warnings that the operator must consider in this manual are classified as
below. Acquaint yourself with the following labels and pictures.
WARNING
If these instructions are not strictly adhered to, there is a risk of fatal injury e.g. from
power supplies or infection.
CAUTION
If these instructions are not strictly adhered to, there is an increased risk of injury and/or
serious functional disruptions to the analyzer.
ATTENTION
Identifies all other situations where increased attention is necessary (e.g. to avoid
damage to the analyzer).
Note
Indicates information to be considered e.g. remarks, etc.
is the international symbol for caution
0 - 2 V 2.1 – Operator's Manual
❚ Safety Precautions
WARNING
Electrical Safety
Never open the back or side panels when the analyzer is connected to the
mains supply (wall socket)! Pull the plug out beforehand!
You can receive an electric shock by touching supply-carrying components.
CAUTION
Flammable and Explosive Materials
Avoid using flammable materials around the analyzer.
Electrical sparks can cause fires and explosions.
Potential Hazards and Safety Precautions
CAUTION
Analyzer in Operation
Never touch the sample pipetter, reagent pipetters, stirrer, rinse units and
all other moving components when the analyzer is operating.
There is a risk of injury from the moving components and the analyzer can
also be damaged.
WARNING
Photometer Lamp
Never look for long periods into the light of the photometer lamp without
eye protection.
If this warning is not heeded, damage to the eyes can occur. Wear
darkened protective goggles to protect yourself from ultra violet light,
when you must look at the light transmitted from the photometer lamp for
long periods.
V 2.1 – Operator's Manual 0 - 3
BM/Hitachi 917
WARNiNG
CAUTION
Samples
1. Avoid direct contact with samples that contain bacteria or are poten-
tially infectious.
If sample material comes in contact with the analyzer surface, clean it
up immediately with a towel.
2. Ensure that the sample contains no fibrin clots, dust or other insoluble
contaminations.
If the sample contains insoluble material, false results can be produced. This applies especially when fibrin clots block the sample
pipetter.
Liquid Waste
1. Potentially infectious waste must be disposed of according to the legal
regulations.
There is a risk of contamination from potentially infectious waste.
2. Contact the manufacturer of the reagent, if you require more informa-
tion about its environmental compatibility.
CAUTION
Correctness/Precision of the Measurements
To ensure that the analyzer operates correctly, controls must be measured
and the functions must be monitored.
Erroneous measurements can lead to a false diagnosis resulting in an
incorrect therapy that puts the patient at risk.
0 - 4 V 2.1 – Operator's Manual
Potential Hazards and Safety Precautions
❚ Safety Precautions During Operation
CAUTION
Correct Usage
1. The analyzer was designed for clinical-chemical analyses, electrolyte analyses,
immunological tests and medical analyses using water-soluble samples and reagents.
Comply with the manufacturer regulations of the reagent when using the tests on the
analyzer.
2. If reagents are used other than those developed by Boehringer Mannheim, then
Boehringer Mannheim guarantees the technical specifications of the analyzer but
takes no responsibility for the measured results.
CAUTION
Operator Qualifications
1. The operation of the analyzer should only be performed under the control of a
qualified person, who has taken part in a recognized training from Boehringer
Mannheim.
2. For clinical tests, the analyzer should only be controlled by a practitioner or a
laboratory doctor.
CAUTION
Operation and Maintenance
1. The operation and maintenance of the analyzer may only be performed according to
the described procedures. No other components other than those specified may be
touched.
2. Never open the screwed down analyzer covers when the analyzer is connected to a
power supply. Contact with the circuit boards can damage the electronic components.
V 2.1 – Operator's Manual 0 - 5
BM/Hitachi 917
3. Never touch the sample pipetter, reagent pipetter, stirrer, rinse units and all other
moving components of the analyzer when it is in operation.
If this precaution is not adhered to, damage or interruption to the analyzer can occur.
4. Never touch the reaction disk, sample disk and reagent disk when they are rotating.
If this precaution is not adhered to, damage or interruption to the analyzer can occur.
CAUTION
Environment Conditions (Installation Conditions)
Consider the specified installation conditions. If the analyzer is to be located somewhere else, contact Boerhinger Mannheim customer support.
CAUTION
Limitations for Samples and Reagents
1. The reaction cells, sample cups and the tubing for liquid waste are not impervious to
organic solutions. Never use organic solutions.
2. Never use samples or reagents that can stick to the sample probe, reagent probes
or the reaction cells. This also applies to samples and reagents that may block the
sample probe or reagent probes. False measurements may be produced.
CAUTION
Loading Samples and Reagents
Only load samples and reagents into the intended positions on the analyzer. Spilt
samples and reagents can cause disruptions to the analyzer. Only load reagents when
the analyzer is in the "stand-by" mode, or when the reagent stop function permits
loading.
If this precaution is not adhered to, damage or interruption to the analyzer can occur.
0 - 6 V 2.1 – Operator's Manual
Potential Hazards and Safety Precautions
CAUTION
Analyzer Cover
The analyzer cover should always be closed during operation. Only open the cover to
load samples, etc.
CAUTION
Sample Disk
Never load new samples or change the sample disk when the LEDs, indicating that the
disk is rotating, are lit or blinking.
LED 1 indicates that sample disk 1 is rotating.
LED 2 indicates that sample disk 2 is rotating.
If this precaution is not adhered to, the analyzer can be damaged.
CAUTION
Reaction Disk
1. Never touch the reaction disk when the analyzer is operating.
2. Always follow the corresponding instructions when removing, loading or replacing
the reaction disk or the reaction cell segments.
If this precaution is not adhered to, damage or interruption to the analyzer can occur.
CAUTION
Reagent Disk
Only open the reagent disk cover in order to replace reagents.
If this precaution is not adhered to, the cooling can be affected thus causing the
reagents to expire. Opening the cover during an analysis causes an analyzer alarm.
V 2.1 – Operator's Manual 0 - 7
BM/Hitachi 917
CAUTION
Reaction Cells
If a reaction cell dries out after use, cracks can occur and contaminations may not be
able to be removed. Therefore, the reaction cells must be stored after use in deionized
water. If the analyzer is not going to be used for more than three days, the reaction cells
must be removed from the reaction disk and must be stored in a 2% solution of
Hitergent.
CAUTION
Switching the Analyzer On
Never switch the analyzer off and then immediately back on. Wait at least 30 seconds
before switching back on.
If this is not adhered to, the analyzer may be damaged.
CAUTION
Handling Detergents
Never touch detergents with bare fingers, this can cause skin damage. Wear rubber
gloves when handling detergents.
CAUTION
Photometer Lamp
Do not touch the hot lamp or lamp housing, there is a risk of burns.
CAUTION
Stirrer
Do not bend the stirring paddle. Bent stirring paddles can cause false measurements.
