Important information NOTE: Read the instructions carefully before installing and using this equipment. The local extractor in the ME EX series is designed to meet the requirements in the ATEX directive 94/9/EC, applicable to equipment intended for use in potentially explosive atmospheres. In order to maintain explosion proof integrity, you must observe the instructions in this manual.
Installation and use The equipment can be delivered partially assembled and installed as per the following description. The equipment can be mounted on a wall or to the ceiling using special brackets. Measure a suitable height for the bracket before mounting the arm to the wall, and check that the existing air duct reaches the hose when fitting to the ceiling, see figures.

Ensure that proper electrical contact is made. Connect the ground cable on the bracket to a suitable connection point with the grounding system of the installation. Important: Take the appropriate action if a risk of corrosion has been assessed at the connection point.
Cleaning Clean the extraction arm in the same way as the other equipment at the worksite, however, at least once a year. Clean when there is no risk of explosion in the environment. Observe the risk of electrostatic discharge from people or cleaning tools where there are dust deposits. People are recommended to wear semi conductive shoes and suitable clothing when cleaning where there is dust with MIE <...
Spare parts and accessories Always state the type designation and serial number of the arm (see rating plate on arm), the number of required spares and the spare part name and number as per the list below, when ordering spare parts or accessories.

Testing and troubleshooting The most important factor for satisfactory explosion protection is that the grounding of the equipment is in good condition. Check this by measuring the resistance with an accurate ohmmeter between the ground connections at the bracket/connection to the extraction duct and suction head. The resistance between the suction head and the ground connection/air duct must not exceed 100Ω.
