Safety notes
WARNING
Death or serious injury due to electric shock
Contact with parts that carry a live current can lead to death or injury.
1 Only use the METTLER TOLEDO power supply cable and AC/DC adapter designed for your
instrument.
2 Connect the power cable to a grounded power outlet.
3 Keep all electrical cables and connections away from liquids and moisture.
4 Check the cables and power plug for damage and replace damaged cables and power plugs.
WARNING
Injury and/or damage due to hazardous substances
Chemical, biological or radioactive hazards can be associated with the substances processed by
the instrument. During dosing procedures, small amounts of the dosed substance may become
airborne and penetrate the instrument or contaminate its surroundings.
The substance characteristics and related hazards is the full responsibility of the instrument owner.
1 Be aware of possible hazards associated with the substance and take adequate safety
measures, e.g., those stated on the safety data sheet provided by the manufacturer.
2 Make sure that every instrument part in contact with the substance will not get altered or
damaged by the substance.
WARNING
Injury or damage due to powder handling
Powders may get compacted in the dosing head and block it. Too much force applied by the
dosing head mechanism may lead to a break and potentially hazardous substances may get
airborne.
1 Handle the dosing heads with care.
2 If the dosing head seems blocked, avoid further dosing. Remove the head from the instrument
and turn it upside down to loosen the powder.
3 Cease work immediately in the event of leak or break.
WARNING
Injury and/or damage due to reacting, flammable, or explosive substances
During the dosing procedure, substances could be combined and cause an exothermic reaction or
explosion. This includes powders, liquids, and gases. It may lead to serious injuries and
significant material damage.
The sample characteristics and related hazards is the full responsibility of the instrument owner.
1 Be aware of possible hazards associated with reacting, flammable, or explosive substances.
2 Ensure a working temperature low enough to prevent the formation of flames or an explosion.
WARNING
Injury or death due to toxic substances
If you use toxic, explosive, or flammable liquids with the pump, the exhaust air will be contam-
inated.
− Connect a tube to the exhaust air outlet to collect the contaminated air.
