1 About this manual
This manual describes the vacuum pump V-700 and V-710 and provides all information required for its safe operation and to maintain it in good working order. It is addressed in particular to laboratory personnel and operators. Because of the technical similarities of the V-700 and V-710 most of the descriptions are based on the V-700.
NOTE
The symbols pertaining to safety (WARNINGS and ATTENTIONS) are explained in chapter 2.

2 Safety
This chapter points out the safety concept of the instrument and contains general rules of behavior and warnings from hazards concerning the use of the product. The safety of users and personnel can only be ensured if these safety instructions and the safety­related warnings in the individual chapters are strictly observed and followed. Therefore, the manual must always be available to all persons performing the tasks described herein.
2.1 User qualification
The instrument may only be used by laboratory personnel and other persons who on account of training or professional experience have an overview of the dangers which can develop when operating the instrument. Personnel without this training or persons who are currently being trained require careful instruction. The present Operation Manual serves as the basis for this.
2.2 Proper use
This instrument has been designed and built for laboratories. Its proper use is the evacuation of laboratory instruments. This is done by means of a PTFE diaphragm pump, with or without regulation through one or more vacuum controllers.
A PTFE diaphragm pump is mainly used for:
• Evacuation of distillation instruments, in particular rotary evaporators
• Vacuum filtrations
• Vacuum drying cabinets
• Drying ovens
2.3 Improper use
Applications not mentioned above are improper. Also, applications, which do not comply with the technical data, are considered improper. The operator bears the sole risk for any damages caused by such improper use.
ATTENTION
Danger of pump destruction or loss of pump performance:
• Never use the pump for pumping liquids or solid particles.
The following uses are expressly forbidden:
• Use of the instrument in rooms which require ex-protected instruments.
•
Processing of samples which can explode or ignite due to a blow, friction, heat, or sparks (e.g. explosives, etc.).
• Use of the instrument for digestions (e.g. Kjeldahl).
• Use of the instrument to produce over-pressure (pressurize a system).
• Use of the instrument at an ambient temperature of > 40 °C.

2.4 Warning notices used in this manual
WARNING
Generally, the triangular warning symbol indicates the possibility of personal injury or even loss of life if the instructions are not followed.
WARNING
Hot surface.
WARNING
Electrical hazard.
WARNING
Biohazard.
ATTENTION
With the general “Read this” symbol, ATTENTION indicates the possibility of equipment damage, malfunctions or incorrect process results, if instructions are not followed.
NOTE
Useful tips for the easy operation of the instrument.
2.5 Product safety
The vacuum pump is designed and built in accordance with current state-of-the-art technology. Nevertheless, risks to users, property, and the environment can arise when the instrument is used carelessly or improperly.
The manufacturer has determined residual dangers emanating from the instrument
• if the instrument is operated by insufficiently trained personnel.
• if the instrument is not operated according to its proper use.
Appropriate warnings in this manual serve to make the user alert to these residual dangers.

2.6 General safety rules
Responsibility of the operator The head of laboratory is responsible for training his personnel.
The operator shall inform the manufacturer without delay of any safety-related incidents which might occur during operation of the instrument. Legal regulations, such as local, state and federal laws applying to the instrument must be strictly followed.
Duty of maintenance and care The operator is responsible for ensuring that the instrument is operated in proper condition only, and
that maintenance, service, and repair jobs are performed with care and on schedule, and by autho­rized personnel only.
Spare parts to be used Use only genuine consumables and genuine spare parts for maintenance to assure good system
performance and reliability. Any modifications to the spare parts used are only allowed with the prior written permission of the manufacturer.
Modifications Modifications to the instrument are only permitted after prior consultation with and with the written
approval of the manufacturer. Modifications and upgrades shall only be carried out by an authorized BUCHI technical engineer. The manufacturer will decline any claim resulting from unauthorized modifi­cations.

4.1 Vacuum pump
4.1.1 Functional principle
The Vacuum Pump V-700/710 serves to evacuate laboratory instruments down to 10 mbar respec­tively 2 mbar pressure by means of a PTFE diaphragm pump. This pump is controlled by a variable speed and single stroke technology. It can be either used as stand-alone instrument or it can be expanded to a complete vacuum system with optional accessories such as vacuum controllers and a secondary condenser.
NOTE
During a stable vacuum control irregular pump motor operation might be audible when the pump is in the change over between speed control and Wankel operation. This is absolutely normal and does not indicate a technical malfunction.
