8/82 Operation Manual Interface I-300
2 Safety
2.1 Intended use
The [Interface I-300] is intended for indicating vacuum within an operating range of
0mbar to ambient atmospheric pressure. The measurement and regulation of the
vacuum is performed by means of a VacuBox. The [Interface I-300] has been
designed and built as an item of laboratory equipment and can be used in
conjunction with the following devices:
Distillation apparatus, especially rotary evaporators
Vacuum-drying cabinets
Vacuum pumps
Recirculating chiller
2.2 Use other than that intended
Use of any kind other than that described in the section Chapter2.1 "Intended use",
page8 and any application that does not comply with the technical specifications
(see Chapter3.6 "Technical data", page23) constitutes use other than that
intended.
In particular, the following applications are not permissible:
Use of the device in areas that require apparatus that is safe to use in potentially
explosive atmospheres.
Use as a calibration device for other equipment.
Operation at pressures above atmospheric
Damage or hazards attributable to use of the product other than as intended are
entirely at the risk of the user alone.
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
applicable 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.

Büchi Labortechnik AG Safety | 2
Operation Manual Interface I-300 9/82
Operator
The operator (generally the laboratory manager) is responsible for the following
aspects:
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 local 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
advances. 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 Faults during operation
If a device is damaged, sharp edges, moving parts 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
inform the operator.
uDo not continue to use devices that are damaged.
2.5 Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
uAlways wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
uMake sure that the personal protective equipment meets the requirements of
the safety data sheets for all chemicals used.
2.6 Modifications
Unauthorized modifications may impair safety and lead to accidents.
uUse only genuine BUCHI accessories, spare parts and consumables.
uTechnical modifications to the device or accessories should only be carried out
with the prior written approval of BÜCHI Labortechnik AG and only by authorized
BUCHI technicians.

3.1 Description of function
The [Interface I-300] is designed for indicating, adjusting and controlling the
complete distillation system. The Interface I-300 settings enable precise specification
of the individual process parameters.For example:
Rotation speed of the evaporating flask
Specified temperature of the heating bath
Specified temperature of the coolant
Specified vacuum pressure
Duration of the distillation process
The pressure is measured and regulated by the associated VacuBox. Measurement is
independent of the solvent used.

3.3.4 LegacyBox (connections)
Connection of a LegacyBox is required whenever legacy BUCHI laboratory equipment
is to be controlled via the [Interface I-300]. The LegacyBox is connected to the
distillation system using a standard BUCHI communication cable and has other
connection options such as an RS-485 communication port. There is also the option
of incorporating pumps of other makes in the Rotavapor system and controlling
them via the interface. In that case, the pump requires a 0 – 10 V input.
The LegacyBox is fixed to a Rotavapor R-300 or a laboratory stand clamp.

The external power supply is only necessary if the LegacyBox is not connected to a
Rotavapor or a vacuum pump and is used for other vacuum control applications
instead. Otherwise the vacuum pump or the Rotavapor supplies the LegacyBox with
power.
