Operating manual 610.44440.40.000 as well as this supplementary operating manual:

 must be read and understood before

commencing any work on or with the unit,

 must be strictly adhered to.  must be available where the unit is used.



WARNING

Improper handling of the system can result in serious or even fatal injuries!

All work on and with the system (transport, installation, commissioning, decommissioning, maintenance, disposal) may only be carried out by trained and reliable skilled staff!

Disclosure, replication, distribution and / or editing of this document and the use and distribution of its content are prohibited if not explicitly permitted. Violation obligates compensation. All rights reserved in case of the issue of a patent, utility patent or design patent.

Concerning 2 Correct use of the equipment

pumps / compressors (units) types: 2BV2 060 2BV2 061 2BV2 070 2BV2 071 2BV5 110 2BV5 111 2BV5 121 2BV5 131 2BV5 161 Additional instructions Concerning explosion protection according to Guideline 94/9/EG

 contains instructions for the unit’s

transportation, installation, start-up, operation, shut-down, storage, maintenance and disposal,

 must have been read and properly understood

by operating and maintenance staff before beginning any work with or on the unit.

 must be complied with and  must be at hand where the unit is installed.

G-BH1 units

 create a vacuum or overpressure.  are used to extract, deliver and compress the

following gases / vapours:

− all dry and damp gases which are not

explosive, combustible, aggressive or poisonous,

− air or air-vapour mixtures.

− in the case of aggressive or poisonous

gases / vapours, please consult the manufacturer.

− the gases / vapours must be free of solid

matter. Small quantities of light suspended matter or liquids can be conveyed along too.

 are suitable for a deep vacuum range.  are equipped with RL 94/9/EG three-phase

drive motors. For more detailed information please consult the motor manufacturer’s accompanying operating instructions.

 are available in two constructions:

− Construction for normal requirements

− Construction for higher corrosion-resistance

and hygiene requirements (only 2BV2 070. 2BV2 071 and 2BV5 ..)

Operating and maintenance personnel

Operating and maintenance personnel for G-BH1 units must be trained and authorised for the work to be carried out.

Work on electrical installations may only be carried out by an electrics specialist. An electrics specialist is someone who can evaluate and identify potential risks for the assigned task as a result of their technical training, knowledge and experience as well as knowledge about relevant regulations.

 are designed for industrial plants.  are designed for continuous operation.

When operating the units, the limiting values listed in chapter 3 operating manual

610.44440.40.000 "Technical Data" are to be complied with.

Scope of application for units according to Guideline 94/9/EG

Inside area of explosion prevention design

G-BH1 units are suitable for conveying gases/vapours where a potentially explosive atmosphere is occasionally expected to be present. This specification includes category 2G for the internal space of the units. If the specified maximum temperatures are complied with, the units are suitable for temperature class T4.

Surrounding area

When rating the device category, both the place where it is installed and its internal space must be taken into consideration. Installing G-BH1 units for category 2G is allowed for areas where potentially explosive gases / vapours are expected to occur occasionally.

Concerning 2 Correct use of the equipment

If the specified maximum temperatures are

Foreseeable misuse

complied with, the units are suitable for temperature class T3.

G-BH1 unit operating liquid



WARNING

The ignition temperature of the operating fluid must be above 150°C [150.00°F].

The chosen operating liquid must comply with the requirements / properties stated below.

It must not corrode or destroy the pump components used.



WARNING

Monitoring of the operating liquid status before starting up as well as monitoring of trouble-free feeding of the operating liquid while in operation should be built into the system.

The system must shut down if there is a failure in the operating fluid feed.

Operating without operating fluid must be avoided under all circumstances.

NOTE

When using operating fluids with a heat capacity of < 3 kJ/kg K, or a boiling point which does not lie 20 K above the input temperature, consult the manufacturer.

The following are forbidden:

 Use of the unit2BV2 060 2BV2 061 2BV2

070 2BV2 071 2BV5 110 2BV5 111 2BV5 121 2BV5 131 2BV5 161 in nonindustrial plants, unless the necessary precautions and protective measures have been taken at the plant, e.g. protection against contact by children's' fingers.

 Setting up and use of units in zones 0, 20, 21

and 22.

 The extraction, transport and condensing

of aggressive or poisonous media unless the units are specifically designed for such media.

 to evacuate, convey and compress explosive,

inflammable, or aggressive mediums, which could damage the slide ring seal.

 To evacuate, convey and compress gases or

gas mixtures which are explosive when air is not present, or may change the unit’s safetyrelevant material properties.

 Operation with a frequency converter.  Operation of the unit at any values other than

those specified in chapter 3 “Technical data” in the 610.44440.40.000 operating manual.

Modifications to the units are forbidden for safety reasons.

The operator is not allowed to carry out maintenance, servicing and repair work which requires the machine to be dismantled.

Operating liquid type:

Normally use water with a pH-value between 6 and 9, or any other liquid compatible with the process. It must be free of:

− Foreign matter and objects:

− Crystalline precipitate substances

− Substances which tend to stick or jam

No precipitate substances may be produced from the operating fluid during the sealing process. Likewise, no substances may be used which tend to polymerise of their own accord or when in contact with propellant gas.

Compatibility must be checked with regards to chemical reactions between the operating liquid and the slide ring seal, the operating fluid and other pump parts as well as the operating fluid and the propellant gas.
