2 Safety
2 Safety BÜCHI Vac V-500/V-501/V-502/V-503
The device is built with state-of-the-art technology and according
to recognized safety regulations. Nevertheless, using this device
can lead to certain risks and dangers:
• If the device is not used according to these instructions.
• If the device 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.
Warning
Surface temperature more than 60°C.
2.2 Requirements for the Operator
The device 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 device.
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 device was designed and built for laboratory use. Its pro-
per use is the evacuation of laboratory vacuum devices up 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

BÜCHI Vac V-500/V-501/V-502/V-503 2 Safety
2.4 Safety Features
Two fuses (3.15 AT) have been built into the device to protect
it from a short circuit. The pump motor is protected from
overheating by a temperature governor. The pump is 100%
free of oil. The bearings do not require lubrication. All
bearings are completed sealed and self-lubricating.
2.5 Improper Use
Any use of the device other than those given above or any
use of the device 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 device 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 device must not be used in the following ways:
• Use of the device 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 device for digestions (e.g., Kjeldahl)
• Use of the pump to produce over-pressure
• Operation of the device in a surrounding temperature
of > 40° C.
2.6 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 secondary condenser.
• Ignition sources in the immediate vicinity of the pump/
pump system outlet.
• Flammable gases or solvent vapors in the immediate
vicinity of the device.
• Damaged glass equipment
• Bent hoses on the outlet side

2.7 Safety Measures
Protective clothing such as goggles and laboratory coats
must be worn during operation of the device.
These operating instructions must be available at all times
to operating personnel at the place of operation of the device
and should be regarded as an integral part of the Büchi
Vac V-500-503. Instructions in other languages, which may
be ordered separately, must also be kept with the device.
Modifications
Modifications of the device 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 for 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 device.
Regional and local statutes and regulations must be observed.
It is forbidden for anyone other than authorized maintenance
personnel to remove the front or back plate using standard
tools. Damaged glass equipment may not be used under
vacuum conditions.
Touching any parts of the device carrying electrical current
can result in fatal injury!

3 Function
The Büchi Vac V-500 is a vacuum pump suitable for evacuating
laboratory equipment to a vacuum of <10 mbar. This is done
with a PTFE diaphragm pump. The pump can be used as an
individual device to create a vacuum and can be expanded to
a complete vacuum system by means of the optional
accessories such as secondary condenser and vacuum
controllers (V-501/502/503).
In the following pages, reference will often be made to pump
inlet and pump outlet.
This distinction is important and can be recognized on the
valve heads as follows. Arrows on both valve heads show the
direction of the gas flow.
The pump inlet , is at the beginning of the arrow, the tip of
the arrow is the pump outlet .
Never turn the valve heads so that the arrows point to one
another!

3.2 Function of the Büchi Vac V-501
Vacuum system with PTFE diaphragm pump V-500 and
secondary condenser, suitable for evacuating laboratory
equipment to a vacuum of <10 mbar. The secondary
condenser removes any solvent vapors following the pump
