2 Safety

The manufacturer shall not be liable for damages due to non-observance of the whole documentation.

2.1 General

These operating instructions contain basic instructions for installation, commissioning, maintenance and in-

spection work which must be obeyed to ensure the safe operation of the machine and prevent physical and

material damage.

Observe the safety instructions in all chapters.

The operating instructions must be read by the responsible technical personnel / user before installing and

commissioning and must be fully understood. The contents of the operating instructions must always be

available on site for the technical personnel / user. Instructions attached directly to the machine must be

obeyed and must always remain legible. For example, this applies to:

• Symbols for connections

• Data plate and motor data plate

• Information and warning signs

The data plates on the vacuum pump may not be removed, even if the machine is resold. For all queries

about the product, please always quote the serial number.

The user is responsible for observing local regulations.

2.2 Labelling of warnings

2.4 Intended use

If not used as intended, this can cause dangerous operating conditions and oxidizing mixtures can be

generated.

The machine is suitable for conveying the following media:

• All non-explosive, non-combustible, non-aggressive and non-poisonous dry gases and gas-air

mixtures

• It is suitable for exhausting air or other gases with increased percentage of oxygen (content by volume

larger than 21 %) and other gaseous oxidising agents.

The machine is permitted to be operated only in such areas that are described in these operating

instructions:

ØOnly operate the machine in technically perfect condition

ØThe machine must only be operated at an ambient temperature and inlet temperature of between 5 and

40 °C

Please contact us for temperatures outside this range

ØThe permissible back pressure may not be exceeded

Maximum permissible back pressure: + 50mbar

ØFor lubrication, use the speciﬁed oil type OXY-GEAR-LUBE 160 only

Any use extending beyond this use is seen as not in accordance with the intended use.

The intended use also includes the compliance with the operating data and operating agents speciﬁed in the

operating instructions, the listed maintenance works, as well as the details in the documentation issued by

the manufacturers of components and attachments.

If used under critical conditions and/or in case of any doubts, please contact the manufacturer. Non-obser-

vance can cause machine failures.

2.5 Inadmissible operating modes

• extracting, conveying and compressing of explosive, inﬂammable, aggressive, oxidative or poisonous

media, e.g. dust as per ATEX zone 20-22, solvents, water steam, liquids or solids

• Erection and operation in potentially explosive environment (explosive gas/vapour/mist-air mixtures or

dust-air mixtures or hybrid mixtures of air and ﬂammable substances)

• Using the machine in non-commercial plants unless the necessary precautions and protective measures

are taken in the plant

• Operation of the machine when it is only partially assembled

• Using the machine in areas with ionising radiation

• Back pressures on the outlet side: > +50mbar

• Modiﬁcations to machine and accessories

• Using oil that have not been approved by Gardner Denver Schopfheim GmbH
