Safety Instructions - IKA LR 1000 basic Mode D'emploi

Safety instructions

General instructions:
• Read the operating instructions fully before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where they
can be accessed by everyone.
• Ensure that only trained staff work with the equipment.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
Device setup
If installation or positioning
DANGER
cannot ensure this access at all
times, an additional EMERGEN-
CY STOP switch that can be eas-
ily accessed must be installed in
the work area.
Pay attention to the danger
spots shown in Fig. 5.1 / Fig. 5.2.
The MV1 valve can become very
hot during operation.
Secure the cooling hoses to the
device. Pressure can build up due
to vaporisation.
The MV1 valve must only be fit-
ted as an inlet (cooling connec-
tion IN).
• Uncontrolled reactions can be triggered by mixing the
heated material insufficiently or by the energy gener-
ated by selecting a speed that is too high. In case of
these and other increased operational hazards, users
must take additional appropriate safety precautions.
In any case, when using critical or hazardous materials
in your processes, IKA recommends to use additional
appropriate measures to ensure safety in the experi-
ment. For example, users can implement measures that
inhibit fire or explosions or comprehensive monitoring
equipment. Furthermore, users must make sure that
the unit switch of the IKA product can be accessed im-
mediately, directly and without risk at any time.
• Set up the device in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• Protect the instrument and accessories from bumping
and impacting.

Work with the device
Beware of hazards due to:
WARNING
- flammable materials
- combustible media with a
low boiling temperature
- glass vessel breakage
- overfilling of media
- unsafe condition of container.
Observe the chapter "technical
data".
The reactor system must al-
ways be ventilated when work-
ing under normal pressure in
order to prevent any pressure
build-up caused by highly vola-
tile gases or unpredictable re-
action pressure gradients. Con-
dense volatile gases using a
cooler with a standard ground
connector (e.g. a reflux con-
denser) on the reactor cover.
Before you fill the reactor ves-
NOTICE
sel, ensure that the reagents
used do not corrode the seal.
The cooling system must be un-
pressurised.
• Only process media that will not react dangerously to
the extra energy produced through processing. This
also applies to any extra energy produced in other
ways, e.g. through light irradiation.
• Do not operate the device in explosive atmospheres,
in the presence of hazardous materials or under water.
• With substances capable of forming an explosive mix-
ture, appropriate safety measures must be applied, e.g.
working under a fume hood.
• The equipment is not designed for overpressure use.
• The equipment is designed for operation at vacuum
settings up to 25 mbar.
• Certain applications and materials may be hazardous. You
should take precautions to prevent contact with, or inha-
lation of, toxic liquids, gases, fumes, vapours or powders.
• Risks may also be posed by biological or microbiologi-
cal substances.
• Observe the maximum permissible temperatures in the
reactor vessel.
• Ensure that the external temperature sensor is inserted
in the media to a depth of at least 20 mm.
• The external temperature sensor must always be im-
mersed in the medium.
• When the reactor vessel or the vessel cover is removed
during operation, the stirring and the heating function
will be switched off automatically. Restart the stirring
and heating function by pressing on knob (A) and (B)
after the reactor vessel or vessel cover is placed and
locked again.
Stirring and dispersing:
Rotating tools are dangerous!
CAUTION
The anchor stirrer and the dis-
persing element must only be
operated when the reactor ves-
sel is fully closed. Do not start
up the laboratory reactor when
it is open.
• Moving and rotating equipment parts also constitute
a hazard.
• If the dispersing element rotate when they are covered
in a product and the reactor is open, this will cause
parts or liquids to be projected outwards.
• The equipment may heat up by stirring.
• Gradually increase the speed.
Heating:
Risk of burns! Exercise caution
DANGER
when touching the heating
block and the glass vessel. The
cover of the vessel could reach
high temperature when you
boil liquid for long time. Pay at-
tention to the residual heat af-
ter switching off.
Only process and heat up any
media that has a flash point
higher than the adjusted safe
temperature limit that
been set. The safe temperature
limit must always be set to at
least 25 °C lower than the fire
point of the media used.
Cooling:
Using the adequate hoses for
CAUTION
cooling purposes.
• Ensure that the thermostat used for tempering is fully
efficient. A defective thermostat can cause uncon-
trolled reactions.
Weighing:
Weighing function integrated
NOTICE
into the LR 1000 control feet.
Unpack and set up cautiously.
Power supply/Switching off the device
• The device will automatically restart in mode B and C
following any interruption to the power supply.
• Always switch the device switch in the OFF position or
disconnect the power before changing and fitting any
accessories.
• The instrument can only be disconnected from the mains
supply by pulling out the mains plug or the connector plug.
• The socket for the mains cord must be easily accessible.
• Socket must be earthed (protective ground contact).
• The voltage stated on the type plate must correspond
to the mains voltage.
Accessories
• Only use IKA approved accessories!
• Use only original IKA spare parts!
• Check the instrument and accessories beforehand for
damage each time when you use them. Do not use dam-
aged components.
• Safe operation is only guaranteed with the accessories
described in the "Accessories" section.
Maintenance:
Covering or parts that are ca-
NOTICE
pable of being removed from
the unit without accessory
equipment have to be reat-
tached to the unit for safe op-
eration in order to prevent, for
example, the ingress of fluids,
foreign matter, etc.
has
• The feet of the equipment must be clean and undamaged.
• The device must only be opened by trained specialists,
even during repair. The device must be unplugged from
the power supply before opening. Live parts inside the
instrument may still be live for some time after unplug-
ging from the power supply.
