Installation, Operation, and Maintenance Instructions
1.0 Handling
1.1 Unpack and handle with care to avoid damage to termination
and other heater components
1.2 Refer to Application Data link for additional information
related to heater system design and use instructions
2.0 Safety
2.1 WARNING: Make sure power supply is turned off before
installation or service of electric heater to prevent electrical
shock or damage to equipment.
2.2 WARNING: Circuit should have separate disconnect means
which shall be capable of being locked in the open position
and also in sight from the heater.
2.3 WARNING: Wiring must conform to the National Electric
Code and Local Regulations and should be performed by a
a qualified electrician. Make sure wiring is of a suitable
temperature rating, amperage rating, and the location.
2.4 WARNING: When servicing, handle with caution, the heater
surface may be hot.
2.5 WARNING: Do not install heater into a medium or an
environment that could result in an explosion, fire, or
hazardous condition. Contact Vulcan regarding heaters that
are specifically designed for hazardous locations.
3.0 Installation and Operation
3.1 Caution: Make sure the heater supply voltage is the same
as the rated heater voltage.
3.2 Caution: Heater should be properly grounded to prevent
electrical shock hazard.
3.3 Caution: Do not support or suspend heater from termination
or wiring.
3.4 A common cause of heater failure is contamination of the
the internal heater components through the termination end
of the heater. Make sure the heater is protected from
contamination in the final application.
3.5 Make sure heater termination is not exposed to water or
other liquids. Make sure that no dripping from
condensation on cold water pipes or other sources can fall on
any exposed electrical wiring connections or components.
3.6. Termination's should be properly tightened and connected
to hook-up wiring. A loose connection will result in over-
heating at the connection and could lead to premature
failure. Where possible, use a wrench or pliers to prevent
twisting of the terminals during installation.
3.7 It is good practice to avoid routing of thermocouples with
power wiring. Use separate conduit. Thermocouples,
thermostat capillary tubes, and wiring should be kept clear
of heater terminals by distance or appropriate insulation.
3.8 Do not use these heaters with explosive gasses or
air mixtures that may result in fire, explosion, or other
hazardous conditions.
3.9 When installing strip heaters, allowance must be made for
linear expansion during operation. Longer units may require
additional clamping of the strip heater to improve contact.
3.10 Do not exceed 110% of rated voltage. Higher voltages result
in higher wattage output which could damage the heater,
system, or medium heated.
4.0 Maintenance
4.1 For most applications, no heater maintenance is required.
4.2 Disconnect line switch prior to any testing or work on the
heater.
4.3 Check heater termination's after the initial 8 hours and tighten
any loose terminal and jumper connections.
4.4 Recheck wiring periodically to ensure wiring has not become
damaged, worn, or loose due to vibration or other application
related conditions. Tighten, repair, or replace as needed.
5.0 Trouble Shooting
5.1 WARNING: Disconnect power supply to heater(s) before
performing any trouble shooting procedures.
5.2 Check supply voltage to heater to ensure there is power.
5.3 Check wiring circuit- make sure heater is properly wired and
all supporting controls, relays, contractors, and other circuit
related switches are also properly wired and functional.
5.4 Check heater(s)- No heat due to a heater failure is generally
due to an open heater circuit. Check heater resistance across
both terminals or leads. A reading of infinity (no continuity)
indicates an open circuit within the element and the heater
must be replaced.
