 must be fully read and understood by

operating or maintenance personnel before beginning any kind of work on or with the unit.

 must be strictly adhered to.  must be at hand where the unit is installed.

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 a 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.

G-BH1 units

reg. 2 Correct Use Of The Equipment

Foreseeable misuse

 are equipped with RL 94/9/EG three-pha se

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

 exist in the following formats:

− single-impeller

− two-impeller, two-stage (for increased

pressure difference)

− two-impeller, double flow. (for increased

conveyance volumes).

 are designed for industrial plants.  are designed for continuou s operation.

When operating the units, observe the limit values and following scope of application listed in chapter 3, “Technical data” of instruction manual

610.44434.40.000.

Scope of Application. Inside area of explosion prevention design

G-BH1 units are suitable for conveying gases and dusts where under normal operating conditions a potentially explosive atmosphere is not expected to be present. If it does occur however, then only temporarily. This specification includes category 3G and 3D for the internal space of the units.

Inside area biogas use

G-BH1 units are suitable for conveying gases with a relative humidity of up to 80% and dusts where under normal operating conditions a potentially explosive atmosphere is not expected to be present. If this should however arise, it will, in all probability, only be temporary. This specification includes category 3G and 3D for the internal space of the units.

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 categories 3/2G and 3/2D is allowed for areas where potentially explosive gases and dusts are expected to occur occasionally.

The use of G-BH1 units for category 3G and 3D is allowed in areas where no potentially explosive atmosphere is present. If it does occur however, then only temporarily.



WARNING

Danger of explosions!

Gases, gas mixtures and dusts which are explosive when air is not present, or may change the machine’s safety-relevant material properties, must not be conveyed.

It is forbidden:

 to use the unit for non-industrial facilities

unless essential precautions and protection measures are fitted, such as guards to protect children's fingers;

 to use the unit for category 3/2GD in areas

where explosive gases and dusts occur constantly, frequently, or for long periods of time;

 to use the unit for category 3GD in areas

where explosive gases and dusts occur constantly, frequently, or for long periods of time;

 to evacuate, convey and compress explosive,

inflammable, or aggressive mediums;

 to operate the unit using limits other then

those stipulated in chapter 3 “Technical data”, p.8 and following pages in the standard operating manual;

 in biogas uses:

− to draw in from explosive areas, or

discharge into explosive areas.

Unauthorised modifications to the units are forbidden due to safety reasons.

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

reg. 3 Technical Data

reg. 5 Installation

reg. 3.1 Mechanical Data Temperature increase

reg. 3.3 Operating conditions



WARNING

Danger of explosion due to the conveyed medium and the unit’s surfaces temperatures exceeding 125°C [257°F].

Operating the unit outside the pressure range indicated on the rating plate is prohibited as this leads to unacceptable temperature increases.

When there is simultaneous limited performance from suctioning and pressure, consult the manufacturer.

Temperature class is complied with.



WARNING

Danger of burns from hot surface on the unit and from hot mediums!

The external surface of the unit can reach temperatures of up to about 125ºC [257 ºF]

 Install the unit in such a way that accidental

contact with its surfaces is not possible.

 Cover the unit with a suitable protection

against contact (e.g. perforated metal cover or wire covering).

reg. 5.1 Setting up explosion prevention

design

Set-up variations / Position

Extra note for vertical set-up: If setting up units vertically, ensure that no

foreign objects can fall into or block the ventilator of the engine by using a suitable protection device according to RL 94/9/EG. The protection device may not affect the engine’s cooling function.

 under operating conditions stated in

instruction manual 610.44434.40.000 and

 during continuous operation and no rmal, non-

frequently recurring start-ups (maintaining a rest period of 5 minutes between two start-up procedures)

reg. 5.1 Setting up for biogas uses

Setting up in zone 2 areas must be carried out in adherence of the respective applicable rules and safety regulations.

 Set up the unit in the open air.

 With obligatory ventilation of the set up space

in accordance with the applicable safety rules for biogas plants.

AND/ OR

 Monitor air in the set up space in accordance

with the applicable safety rules for biogas plants.
