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*
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.
