• 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.
• The maintenance operation for Ex-approved products must be made in conformity to the
international or national standards (IEC/EN 60079-17).
Product and product handling requirements
These are the product and product handling requirements for Ex-approved products in potentially

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
