Introduction and Safety
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:
• All work on the product must be carried out by certified electricians and ITT-authorized
mechanics. Special rules apply to installations in explosive atmospheres.
• All users must know about the risks of electric current and the chemical and physical
characteristics of the gas and/or vapor present in hazardous areas.
• Any maintenance for Ex-approved products must conform to international and national
standards (for example IEC/EN 60079-17).
Product and product handling requirements
These are the product and product handling requirements for Ex-approved products in
potentially explosive atmospheres:
• Only use the product in accordance with the approved motor data stated on the
nameplates.
• The Ex-approved product must never run dry during normal operation. Dry running during
service and inspection is only permitted outside the classified area.
• Never start a pump without the proper priming.
• Before you start working with the product, make sure that the product and the control panel
are isolated from the power supply and the control circuit, so they cannot be energized.
• Do not open the product while it is energized or in an explosive gas atmosphere.
• Make sure that thermal contacts are connected to a protection circuit according to the
approval classification of the product.
• Intrinsically safe circuits are normally required for the automatic level-control system by the
level regulator if mounted in zone 0.
• The yield stress of fasteners must be in accordance with the approval drawing and the
product specification.
• Do not modify the equipment without approval from an authorized ITT representative.
• Only use parts that have been provided by an authorized ITT representative.
Equipment for monitoring
For additional safety, use condition-monitoring devices. Condition-monitoring devices include
but are not limited to these devices:
• Pressure gauges
• Flow meters
• Level indicators
• Motor load readings
• Temperature detectors
• Bearing monitors
• Leak detectors
• PumpSmart control system
