2 Safety
2.1 Intended use
The Vacuum Pump V-600 has been designed and built as an item of laboratory
equipment. Its intended use is the evacuation of laboratory apparatus. This is done by
means of a PTFE-diaphragm pump – with or without regulation by a vacuum con-
troller.
PTFE-diaphragm pumps are used primarily for the following applications:
Evacuating distillation apparatus, in particular rotary evaporators (Rotavapor®)
Vacuum filtration
Vacuum-drying cabinets
Drying kilns
2.2 Use other than that intended
Use of any kind other than that referred to and any application that does not comply
with the technical specifications constitutes use other than that intended. The opera-
tor alone is liable for any damage brought about by use of the device in a manner
other than that intended.
In particular, the following applications are not permissible:
Use in areas which require explosion-safe apparatus.
Pumping of liquids and solid particles.
Processing samples which could be caused to explode or ignite by impact, friction,
heat or sparks (e.g. explosives).
Use for analysis (e.g. Kjeldahl).
Generation of positive pressure (pressurizing a system).
Operation at ambient temperatures >40 °C.
2.3 Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater
dangers.
The device may only be operated by suitably qualified laboratory staff.
These operating instructions are aimed at the following target groups:
Users
Users are persons that meet the following criteria:
They have been instructed in the use of the device.
They are familiar with the contents of these operating instructions and the applica-
ble safety regulations and apply them.
They are able on the basis of their training or professional experience to assess
the risks associated with the use of the device.

Operator
The operator (generally the laboratory manager) is responsible for the following as-
pects:
The device must be correctly installed, commissioned, operated and serviced.
Only suitably qualified staff may be assigned the task of performing the operations
described in these operating instructions.
The staff must comply with the locally applicable requirements and regulations for
safe and hazard-conscious working practices.
Safety-related incidents that occur while using the device should be reported to the
manufacturer ([email protected]).
BUCHI service technicians
Service technicians authorized by BUCHI have attended special training courses and
are authorized by BÜCHI Labortechnik AG to carry out special servicing and repair
measures.
2.4 Residual risks
The device has been developed and manufactured using the latest technological ad-
vances. Nevertheless, risks to persons, property or the environment can arise if the
device is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual dangers.
2.4.1 Dangerous vapors
Distillation can produce dangerous vapors that are capable of causing life-threatening
toxic effects.
uDo not inhale any vapors produced during distillation.
uEnsure that vapors are removed by a suitable fume hood.
uOnly use the device in well ventilated areas.
uIf vapors escape from joints or connections, check the seals concerned and re-
place them if necessary.
uDo not distill any unknown fluids.
uObserve the safety data sheets for all fluids used.
2.4.2 Faults during operation
If a device is damaged, sharp edges or exposed electrical wires can cause injuries.
uRegularly check device for visible damage.
uIf faults occur, switch off the device immediately, unplug the power cord and in-
form the operator.
uDo not continue to use devices that are damaged.
2.4.3 Hot surfaces
The surfaces of the device can become very hot. If touched they can cause skin
burns.
uDo not touch hot surfaces or else wear suitable protective gloves.

3 Product description
3.1 Description of function
The Vacuum Pump V-600 is intended for evacuating laboratory apparatus to a termi-
nal vacuum of 1.5mbar (±1mbar). It can be operated either as a standalone device
or combined with optional accessories (see Chapter3.3 "Specifications supplied",
page16).
Once switched on, the Vacuum Pump V-600 runs in continuous mode unless it is
connected to the Interface I-300/I-300 Pro unit. In unregulated continuous mode, the
pump runs at a maximum speed of 1500 rpm and generates a terminal vacuum of
1.5mbar (±1mbar). The time required for evacuation depends on the size (volume)
of the vessel.
When operating as a standalone unit, the Vacuum Pump V-600 automatically
switches to energy saving mode after 1 hour of operation. In energy saving mode, the
Vacuum Pump V-600 runs at 80% of maximum speed but still generates the same
terminal vacuum of 1.5mbar (±1mbar). After 2 hours of operation, the speed re-
duces to 50% of maximum while still maintaining the same terminal vacuum.

5.1 Important considerations prior to commissioning
WARNING
Risk of irritation of mucous membranes and poisoning from inhalation
of hazardous gases and vapors.
In the process of evacuation it is possible that hazardous substances may be pumped
out at the same time and released into the atmosphere. In addition, it is possible for
such substances to collect as condensation at leaking connections.
uOperate the pump inside a fume hood.
uDirect vapors from the pump outlet into the fume hood.
uIf necessary, wear a face mask and safety goggles.
uIf necessary, only handle pump and accessories with protective gloves.
WARNING
Risk of fire or explosion from flammable solvent vapors.
In the process of evacuation, it is possible for solvent vapors to get into the inside of
the pump and catch fire or explode due to the electric current.
uFollow the guidance notes for the solvents used.
uConnect a Woulff bottle upstream of the pump intake.
uOperate the pump inside a fume hood.
CAUTION
Health risks when handling corrosive substances.
uWhen working with strong acids or caustic solutions, always wear personal protec-
tive equipment (safety goggles, protective clothing, protective gloves).

20/65 Operation Manual Vacuum Pump V-600
5.2 Installation site
IMPORTANT
Risk of property damage from falling equipment (e.g. in an earthquake)
uSecure the Vacuum Pump against falling by means of the lashing eye on the rear
of the device, see Chapter3.2.2 "Rear view", page12.
The installation site must meet the following requirements:
Firm and level surface: at least 330 mm x 330 mm (W x D)
Height: at least 300 mm
Set up inside a fume hood or
feed the pump outlet into the fume hood
Sufficient clearance on all sides of the device (approx. 10 cm) in order to ensure air
circulation
Clear air outlet at the rear (ventilation slots must be kept clear)
The V-600 is intended for use in laboratory environments. See Chapter3.4.2 "Ambi-
ent conditions", page17.
