Subject to change without notice
Every effort has been made to ensure that this unit will run with a minimum of user input
or maintenance. However, there are still precautions to be taken whenever operating,
performing maintenance, or servicing this unit. This unit makes use of heating elements
and electrical components, both of which pose inherent burn, fire, and electrical shock
hazards. These hazards can result in injury to personnel, the plant, and/or the process.
Please note the following to aid in the operation of your unit and to decrease the risk of the
above-mentioned hazards.
Precautions:
• Carefully and completely read through this and all accompanying literature completely
to verify that you understand the functionality and features of this system. Please
become familiar with the integral safeties and controls within this system, and know their
functions.
• Always disconnect all electrical power prior to installing, servicing, or replacing
electric heating elements and/or assemblies. The means for disconnection must be
incorporated in the fixed wiring in accordance with the wiring rule.
• Electrical termination enclosures should be selected to match the application’s
environment and be able to withstand worst-case failures, especially in hazardous
locations.
• Avoid fire hazards. Electric heaters and their components can develop temperatures
that produce an auto-ignition source. Avoid mounting heaters in atmospheres containing
combustible gases, vapor, or dust. Article 501 of the National Electrical Code (NEC)
requires that the maximum sheath temperature when the heater is continually energized
not exceed 80 percent of the surrounding atmosphere’s auto-ignition temperature.
• Avoid having heaters come in contact with combustible materials. Keep heaters far
enough away from combustible materials to prevent ignition.
• Be aware of the labeling on the unit, such as a lightning-bolt warning symbol, which
alerts you to a safety hazard that could harm you or the unit.
• While servicing or operating this unit it is advisable to remove all metal from the
individual working on the unit. This includes metal bracelets, rings and jewelry, as well
as metal rim glasses and wristwatches.
• Keep your clothing, hands, and feet dry at all times whenever working with electrical
equipment.
• Pull the fuses, open the circuit breakers, or disconnect the circuits from their source of
power to protect yourself, the test equipment and the equipment under test.
• Do not troubleshoot or service a circuit with the primary power applied.
• If it becomes necessary to work on the unit with the power applied, keep one hand free
at all times (behind you).
