page 12 of 106To the best of our knowledge the equipment is in compli-ance with the requirements of the applicable EC-directivesand harmonized standards (see ”Declaration of Conformi-ty”) with regard to design, type and model. Directive IEC1010 (EN 61010-1) gives in detail the conditions underwhich the equipment can be operated safely (see also IPdegree of protection, ”Technical data”, pg. 19).Adopt suitable measures in case of differences from rec-ommended conditions, e.g., using the equipment outdoors,installation in altitudes of more than 3300 ft (1000 m) abovemean sea level, conductive pollution or external conden-sation on the pump.Pay attention to the permissible maximum ambient andgas inlet temperatures (see ”Technical data”, pg. 19).Do not operate this product near flames.Operating conditions➨ These pumps are not approved for operation in po-tentially explosive atmospheres. Do not operate thepumps in potentially explosive atmospheres.➨ These pumps are not approved for the pumping ofpotentially explosive atmospheres. Do not pumppotentially explosive atmospheres.➨ The pumps are not suitable to pump any of the sub-stances listed below.Do not pump:- unstable substances- substances which react explosively under impact(mechanical stress) without air- substances which react explosively when being ex-posed to elevated temperatures without air,- self inflammable substances,- substances which are inflammable without air- explosive substances.NOTICE
