Artisan Technology Group RV 05 basic Manual De Instrucciones página 11

Please observe the information on the hazardous substance
categories for handling solvents and toxic or biological sub-
stances.
Always handle distillation fluids in the proper manner.
Adhere to the relevant regulations when working with explosive
substances and their compounds.
The appliance must not be operated in explosive atmospheres
or under water.
The device must only be used under an all side-closed exhaust,
or a comparable protective device.
Ensure that the appliance is on a flat, stable, non-slip surface.
Align the feet according to the appliance instructions (see
"Assembly" section). Always check before starting up that the
cantilever is fitted to the stand in accordance with the assemb-
ly instructions for drive RV 05 basic Depending on the structure
of the device, there may be a risk to the stationary stability. You
should therefore make certain the device is safe and stable each
time before placing it in service.
Glass parts should be checked over carefully for damage (for
example cracks) each time before placing the unit in service.
Damaged glass parts must not be used, as they can break
during operation. Glasses must be fitted without tension. When
using glass test equipment, it is important to note that bursting
can occur because of tension resulting from incorrect assembly,
because of external mechanical impact or local temperature
peaks. Evacuated glass vessels must not be heated on one side;
the evaporating flask must rotate during the heating phase.
Adapt the quantity and the type of distilland to the size of the
distillation equipment. The cooler must work properly. Monitor
the coolant flow rate at the cooler outlet (see information:
"Starting up").

Tasks with the RV 05 basic must only be performed when ope-
ration is monitored.
Operation with excess pressure is not permitted!
The glass equipment must always be ventilated when working
under normal pressure (e.g. open outlet at cooler) in order to
prevent a pressure build-up due to extremely volatile gases or
an unknown pressure build-up. Please note that dangerous con-
centrations of gases, vapours or particulate matter can escape
through the outlet at the cooler. Take appropriate action to avoid
this risk, for example, downstream cold traps, gas wash bottles
or an effective extraction system.
The appliance is designed for operation under a vacuum of up to
10 mbar. When carrying out vacuum distillation, uncondensed
vapours must be condensed out or safely dissipated. When
carrying out vacuum distillation, equipment must be evacuated
prior to heating (see "Starting up" section). The equipment
must only be aired again after cooling. If there is a risk that the
distillation residue could disintegrate in the presence of oxygen,
only inert gas must be admitted for stress relief.
Prevent peroxide from forming!
Liquids which are prone to forming organic peroxides must be
examined for peroxides prior to distillation and evaporation. Any
peroxides detected must be removed. Many organic compo-
unds are prone to the formation of peroxides e.g. dekalin, diet-
hyl ether, dioxane, tetrahydrofuran, as well as unsaturated
hydrocarbons, such as tetralin, diene, cumene and aldehydes,
ketones and solutions of these substances.
ATTENTION! Organic peroxides can build up in the distil-
lation and waste steam residue of these liquids and soluti-
ons and disintegrate explosively! Liquids which are prone to for-
ming organic peroxides must be kept away from light, especially
UV radiation.
