2 Safety
2 Safety
The apparatus is built with state-of-the-art technology and
according to recognized safety regulations.
Nevertheless, using this apparatus can lead to certain risks
and dangers:
• If the apparatus is not used according to these instructions.
• If the apparatus is used by personnel who have not been
properly trained.
2.1 Symbols
Stop
Information about risks which can lead to extensive property
damage or to serious or life-threatening personal injury.
Warning
Information about risks which can lead to damage to one’s
health or to property damage.
Reference
Information which refers to technical requirements. Failure to
heed these requirements can lead to malfunctions, poor economic performance, and production losses.
2.2 Requirements for the User
The apparatus may be used only by laboratory personnel or
other persons who, due to their training or professional experience, are capable of recognizing possible dangers which might
arise from the use of the apparatus.
Personnel who do not have this training or who are presently
in training must be given careful and exact instruction. These
operating instructions are intended for use as a basis for such
instruction.
2.3 Proper Use
The apparatus was designed and built for laboratory use. Its
proper use is the evacuation of laboratory vacuum apparatus
to <10 mbar. This is done by means of a PTFE diaphragm
pump, with or without regulation through one or more vacuum
controllers.
Uses:
• Evacuation of distillation apparatus, in particular rotation
evaporators
• Vacuum filtrations
• Vacuum drying cabinets
• Drying ovens

2.4 Improper Use
Any use of the apparatus other than those given above or
any use of the apparatus which is not in accordance with the
technical data shall be regarded as a misuse. The operator
bears the sole responsibility for any and all damage which
may result from such misuse. The apparatus is not suitable
for pumping liquids or solid particles. The result of such a use
would be the destruction of the pump or a loss in performance
capability.
In particular, the apparatus must not be used in the following
ways:
• Use of the apparatus in rooms which require ex-protected
apparatus.
• Processing of samples which can explode or ignite due to
a blow, friction, heat, or sparks (e.g., explosives, etc.).
• Use of the apparatus for digestions (e.g., Kjeldahl).
• Use of the pump to produce over-pressure.
• Operation of the apparatus in a surrounding temperature
of <5° C, >40° C.
• The top of the apparatus must not be used as storage
space.
2.5 General Risks
In general, risks can arise from:
• Glass parts which are not suitable for use under vacuum
conditions.
• Solvents which can react with one another if they mix in
the pump or in the additional condenser.
• Ignition sources in the immediate vicinity of the pump/pump
system outlet.
• Flammable gases or solvent vapors in the immediate vicinity
of the apparatus.
• Damaged glass equipment.
• Bent, leaking, or brittle hoses.
2.6 Safety Measures
Protective clothing such as goggles and laboratory coats
must be worn during operation of the apparatus.
These operating instructions must be available at all times to
operating personnel at the place of operation of the apparatus
and should be regarded as an integral part of the Büchi Vac
V-511-513. Instructions in other languages, which may be
ordered separately, must also be kept with the apparatus.

Modifications
Modifications of the apparatus or of spare parts or of accessories as well as the use of spare parts or accessories other
than those mentioned in these operating instructions is allowed
only with the prior written permission of BÜCHI Labortechnik
AG.
Responsibility of the Operator
The operator is responsible for the instruction of his personnel.
Copies of these operating instructions in various languages
can be ordered for this purpose.
The operator shall inform the manufacturer without delay of
any safety-related events which might occur during operation
of the apparatus.
Regional and local statutes and regulations must be observed.
It is forbidden for anyone other than authorized maintenance
personnel to remove any parts not described in these operating
instructions. Damaged glass equipment may not be used under
vacuum conditions.
Touching any parts of the apparatus carrying electrical current
can result in fatal injury!
2.7 Safety Features
Electronics
• The apparatus and the vacuum controller are equipped
with fuses
• The motor is equipped with protection from overheating
Operation
• If the absolute pressure exceeds 1400 mbar, the built-in
aeration valve on the Vacuum Controller V-800 opens automatically.
Glass
• Use of high-quality, inert borosilicate glass 3.3
• Screw-on hose connections to prevent glass breakage
• Plasticized separator on the valve unit
Protective Shield
The protective shield prevents injury to the operator from splinters in the event of glass breakage.

BÜCHI Vac V-511/512/5133 Function
3 Function
3.1 General
The system V-511 consists of a PTFE diaphragm pump and
an integrated additional condenser, without the Vacuum Controller V-800. This system runs in continuous operation with
the main switch turned on.
The systems V-512 and V-513, with the integrated Vacuum
Controller V-800, create and regulate a vacuum and maintain
it at a constant level by automatically compensating for any
loss of vacuum in the evacuated device and returning it to the
selected set pressure. This is accomplished by turning the integrated PTFE diaphragm pump on and off directly.
The vacuum, which is selected according to the solvent (cf.
Page 27), permits almost 100% condensation in the condenser
of the distillation apparatus. The result is a massive reduction
in solvent emissions. The integrated additional condenser assures that any solvent vapors which might have been suctioned off will be condensed out to the physical limit following the
pump.
In addition, the cooling water can be controlled during distillation. This can be handled by the cooling water valve, which is
available as an option. Up to 95% of the water can be saved
with this device.
Additional functions are
• Automatic performance of distillations until dry, if this is physically possible without a loss of solvents (씮 redistillation!)
• Automatic continued distillation until completion of a distillation which has been started manually (e.g., with a mixture
of problematic solvent mixtures)
