2.4 Use in explosion-prone areas
Do not use the equipment in explosion-prone areas. The equipment is not protected
against explosions. It is not equipped with Ex or ATEX protection.
2.5 Responsibilities of the operator
 Only operate the equipment in perfect condition, contact a certified Heidolph Service
representative if equipment does not meet the outlined conditions for operation.
 Verify that only qualified personnel operate the equipment with the appropriate per-
sonal protective protection.
 Verify that personnel have received safety instructions for working responsibly and
safely in the laboratory.
 Verify that the rotary evaporator is set up in a safe and suitable location.
 Verify that the basic device is only plugged to or unplugged from the heating bath if
the main switch is switched off and/or the main power supply is disconnected.
Depending on the media (chemicals) used:
 Verify that the set up and the operation are only within the designated buildings with
the proper equipment for laboratories.
 Verify that the rotary evaporator is only operated in conjunction with a ventilation
system (refer to DIN EN 14175 and DIN 12924).
Ventilation system:

at least 10 times the air exchange

monitored for malfunctions
2.6 Responsibilities of the operating personnel
 Verify that the distillation material can be evaporated safely and that the distillation
residue is not explosive.
 Verify that work using an open flame is not conducted in the surroundings of the
rotary evaporator (explosion risk).
 Verify that the flow rate of < 1 m/s is guaranteed when suctioning liquids that contain
combustible materials (electrostatic charge; ignition risk).
 Verify that gases of explosion group IIC do not occur in materials or chemical reac-
tions, such as hydrogen.
 Verify that equipment that is an emission or radiation source (electromagnetic
waves) for the frequency range (3* 10
11
Hz to 3* 10
15
Hz) is not operated or attached.
 Verify that equipment that is an emission or radiation source for ionizing waves or
that is within the ultrasound range is not operated or attached.
 Verify that adiabatic compression and shock waves do not occur (shock wave igni-
tion).
 Verify that the use of substances with the risk of an uncontrolled release of energy
associated with a rise in pressure is prohibited (exothermic reaction; self-ignition of
dust).
 Verify that the glass surfaces are wiped off by using only damp cloths.
 Wear suitable protective clothing for activities on the rotary evaporator a (with gog-
gles and gloves, if necessary).
 Avoid pressure on the LCD screen, it is not intended to be a touch screen interface.
 Verify that the maximum excess pressure of the coolant equals no more than 1 bar
in the condenser.
 Verify that the basic device is only plugged to or unplugged from the heating bath if
the main switch is switched off and/or the main power supply is disconnected.
