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.

Potential Hazards and Safety Precautions

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.

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.

BM/Hitachi 917

WARNiNG

Samples

1.Avoid direct contact with samples that contain bacteria or are potentially 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.

CAUTION

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 information 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.
