Operate the acetylene cylinder only in an upright position and secured against fall-
ing over. When the cylinder pressure is lower than 100 kPa, the acetylene cylinder
must be replaced to avoid acetone entering the automatic gas control.
The operator must carry out weekly safety checks regarding the status and for leaks
on all gas supplies and connectors including the ones on the device itself. Possible
pressure losses from closed systems and lines under pressure are to be determined.
Leaks and damaged must be repaired without delay.
The gas supply must be closed prior to inspections, service and repairs!
After successful repair and service of the components of the compressed air cylin-
ders or system the device must be checked for sound operation prior to recommis-
sioning!
Unauthorized assembly and installation are not permitted!
After changing the gas cylinder, thoroughly ventilate the cylinder location.
The operator is responsible for the selection of substances used in the process as well
as for their safe handling. This is particularly important for radioactive, infectious, poi-
sonous, corrosive, combustible, explosive and otherwise dangerous substances.
Observe the following notes:
When handling dangerous substances local safety codes and guidelines must be
observed.
Warnings on the labels must always be observed. Only use labeled tubes. Use suita-
ble body protection (laboratory coat, safety goggles and rubber gloves) when han-
dling samples.
The novAA 800 must only be operated under an activated laboratory exhaust hood
(hazards arising from the formation of ozone, combustion gases produced by the
samples, poisonous and combustible by-products from sample preparation pro-
cesses).
Keep flammable and explosive substances away from the flame.
Cleaning with hydrofluoric acid must be carried out in an exhaust chamber. The
operator must wear a rubber apron, gloves and a face mask when handling hydro-
fluoric acid.
Sodium borohydride (NaBH
tremely aggressive. Avoid dripping and spilling of reduction agent.
Biological samples must be handled according to local guidelines regarding the
handling of infectious material.
When measuring material containing cyanide you have to make sure that prussic
acid cannot be generated in the waste bottle, i.e. the waste solution must not be
acidic.
Ensure that all residue liquid from the nebulizer and the automatic sampler is di-
rected into the waste bottle supplied.
The operator is responsible for ensuring that waste materials such as drained cool-
ant and residue liquid from the waste bottle are disposed of in an environmentally
responsible manner and according to local regulations.
