7 You must use your pump as specified in thismanual. Read this manual before you install and operate your safety information is highlighted as WARNING and CAUTION instructions; youmust obey these instructions. The use of WARNINGS and CAUTIONS is defined units used throughout this manual conform to the SI international system of units accordance with the recommendations of IEC1010, the following warning symbols are onthe pump:Warning - refer to accompanying - risk of electric - hot - risk of catastrophic are given where failure to observe the instruction could result in injury or death to are given where failure to observe the instruction could result in damage to the equipment, associated equipment and , RV5, RV8 and RV12 Rotary Vane directive implications!

8 This equipment is designed to meet the requirements of Group II Category 3 equipmentin accordance with Directive 94/9/EC of the European Parliament and the Council of 23rdMarch 1994 on the approximation of the laws of the Member States concerning equipmentand protective systems intended for use in potentially explosive atmospheres. (The ATEXD irective).The ATEX Category 3 applies in respect of potential ignition sources internal to theequipment. An ATEX Category has not been assigned in respect of potential ignitionsources on the outside of the equipment as the equipment has not been designed for usewhere there is an external potentially explosive is no potential source of ignition within the pump during normal operation but theremay be potential sources of ignition under conditions of predicted and rare malfunction asdefined in the Directive.

9 Accordingly, although the pump is designed to pump flammablematerials and mixtures, operating procedures should ensure that under all normal andreasonably predicted conditions, these materials and mixtures are not within explosivelimits. Category 3 is considered appropriate for the avoidance of ignition in the case of arare malfunction which allows flammable materials or mixtures to pass through the pumpwhile within their explosive limits.!When flammable or pyrophoric materials are present within the equipment you must:!Not allow air to enter the equipment.!Ensure that the system is leak tight.!Use an inert gas purge (for example, a nitrogen purge) to dilute any flammable gases orvapours entering the pump inlet, and/or use an inert gas purge to reduce theconcentration of flammable gases or vapours in the pump and in the exhaust pipelineto less than one quarter of the gases' published lower explosive limits (LEL).
