Regular standards
WARNING:
Use of equipment unsuitable for the environment can pose risks of ignition and/or explosion.
Ensure that the code classifications on the pump are compatible with the specific environment
in which the equipment is to be installed. If they are not compatible, do not operate the
equipment and contact an ITT representative before proceeding.
All standard products are approved according to CSA standards in Canada and UL standards
in USA. The drive unit degree of protection follows IP68. See the nameplate for maximum
submersion, according to standard IEC 60529.
All electrical ratings and performance of the motors comply with IEC 600341.
Safety regulations for Ex-approved products in potentially explosive
atmospheres
Description of ATEX
The ATEX directives are a specification enforced in Europe for electrical and non-electrical
equipment. ATEX deals with the control of potentially explosive atmospheres and the
standards of equipment and protective systems used within these atmospheres. The relevance
of the ATEX requirements is not limited to Europe. You can apply these guidelines to
equipment installed in any potentially explosive atmosphere.
Guidelines for compliance
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 ITT representative. When installing or maintaining explosion-proof
pumps, follow these guidelines:
• Always install ATEX-approved equipment in compliance with the directive and applicable
standards (IEC/EN 60079–14).
• Do not install explosion proof products in locations that are classified as hazardous in the
national electric code, ANSI/NFPA 70–2005.
WARNING:
Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining devices
can cause trapped liquid to rapidly expand and result in a violent explosion. This manual clearly
identifies accepted methods for disassembling units. These methods must be adhered to.
Never apply heat to aid in their removal unless explicitly stated in this manual.
If there are any questions regarding these requirements, the intended use, or if the equipment
requires modification, contact an ITT representative before you proceed.
Personnel requirements
ITT disclaims all responsibility for work done by untrained and unauthorized personnel.
These are the personnel requirements for Ex-approved products in potentially explosive
atmospheres:
•
mechanics. Special rules apply to installations in explosive atmospheres.
•
characteristics of the gas and/or vapor present in hazardous areas.
