Safety regulations for Ex-approved products in potentially explosive atmospheres
General guidelines
ATEX compliance is only fulfilled when the pump is operated within its intended use, for
example within its intended hydraulic range. The conditions of the service must not be
changed without approval of an authorized Xylem representative. When installing or
maintaining ATEX-compliant pumps, follow these guidelines:
• Always install ATEX-approved equipment in compliance with the directive and
applicable standards (IEC/EN 60079–14).
• Always install FM-approved products according to ANSI/NFPA 70-2005.
WARNING:
Installation, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling units. These methods must be adhered to. Trapped liquid can rapidly
expand and result in a violent explosion and injury. Never apply heat to impellers,
propellers, or their retaining devices to aid in their removal.
If there are any questions regarding these requirements, the intended use, or if the
equipment requires modification, contact an Xylem representative before you proceed.

characteristics of the gas and/or vapor present in hazardous areas.
