General safety instructions
The device has been constructed according to state-of-the-art technology and recognized safety regulations. However, risks may still arise during installation, operation and maintenance.
Please observe the safety instructions and warning notices.
The safety instructions provided in this chapter are supplemented by specific warning notices in the following chapters. This warning notice explains exactly how you must behave in order to protect yourself, others and objects from damage.
These operating instructions are a component of the device described here.
Please ensure the operating instructions are available at all times.
Please pass on the operating instructions to the subsequent owner.
The device may only be used under the following circumstances:
The device is in full working order.
The device is used according to its intended purpose.
All operators of the device possess the necessary safety and risk awareness.
The instructions stipulated in this instruction manual are followed.
Errors must be eradicated immediately; especially those which jeopardize safety.
Intended use
The device is a magnetic stirrer with a heating function, suitable for continuous operation. The device stirs and/or heats substances in a container. A magnetic stir bar, which is guided by a magnet, moves to administer stirring.
A suitable operating location for the device is one of the following areas: Chemical and biological laboratories in industry and universities
In order to use the device according to its intended use, please also observe these operating instructions, the safety instructions and the instructions provided for cleaning (see chapter "Cleaning").
Uses not permitted
Any use which deviates from the device's intended use is considered to be improper. The manufacturer does not accept liability for any damages resulting from non-permitted uses. The risk is carried by the operator alone.
Do not use the device in potentially explosive areas. The device is not protected against explosion.
Do not insert any objects into the area between the hotplate, the cover plate and the base of the device.
Do not cover the ventilation slots.
Use in potentially explosive areas
Do not use the device in potentially explosive areas. The device is not protected against explosion. There is no explosion or ATEX protection available.
Operating company’s obligations
Only operate the device in full and proper working order.
Ensure that only qualified personnel operate the device.
Ensure that the personnel has received safety instructions in order to guarantee responsible and safe work procedures in the laboratory.
Ensure that the device is positioned in a suitable location.
Ensure that the device is sufficiently stable.
Ensure that installation and operation of the device is only carried out in facilities which are fitted with the appropriate laboratory equipment (e.g. with air extraction units).
2
Operating personnel’s obligations
Ensure that work which uses naked flames is not carried out in the vicinity of the device (risk of explosion).
Ensure that the flow rate when removing liquids with flammable materials remains at < 1 m/s (electrostatic charge; risk of ignition).
Ensure that gases classified in explosion group IIC are not produced by materials or during chemical reactions, e.g. hydrogen.
Ensure that no devices are operated or assembled which are emission or radiation sources (electromagnetic waves) for the frequency range (3×1011 Hz bis 3×1015 Hz).
Ensure that no devices are operated or assembled which constitute emission or radiation sources for ionizing radiation or in the ultrasonic range.
Ensure that no adiabatic compression or shock waves occur (shock wave combustion).
Please wear the appropriate protective clothing when working on the machine (protective glasses and if necessary, safety gloves).
Ensure that sufficient heat transfer media are used.
Ensure that the correct heat and cold protection is used in relation to the media implemented.
Please avoid putting pressure on the display.
Personnel qualification
The target group for this device is qualified personnel. The device may only be operated by individuals who have been instructed in its proper use by qualified personnel.
NOTICE Operating instructions
These operating instructions must be followed, read and understood by all persons working on the device (acknowledgment of the safety instructions is particularly important).
Safety-conscious operation
Heidolph Instruments does not accept liability for personal injury or damage to property which may result from improper and unprofessional working procedures.
The following regulations must be observed:
laboratory guidelines
accident prevention regulations
the Ordinance on Hazardous Substances
other generally recognized regulations of safety engineering and industrial medicine
local regulations
Safety devices on the unit
The safety circuit switches itself off under the following circumstances:
The preset hotplate temperature (set value) is exceeded by the safety temperature (max. 25 °C) (only for MR Hei-Tec in Precise-Mode).
The hotplate temperature measured (actual value) is greater than 360 °C.
Sensor break or sensor shorted in the temperature sensor of the safety circuit.
Sensor break or sensor shorted in the temperature sensor of the control circuit.
Sensor break or sensor shorted in the safety circuit of the external temperature sensor.
Sensor break or sensor shorted in the control circuit of the external temperature sensor.
The sensor difference is too great.
