Component Tubular  Heaters

Installation, Operation, and Maintenance Instructions

1.0 Handling

	1.1 	Unpack and handle with care to avoid damage to heater 
	
	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. 

	3.7   	Do not use these heaters with explosive gasses or 
	        	air mixtures that may result in fire, explosion, or other
	        	hazardous conditions.

	3.8	Component tubular heaters are typically designed and
		configured for a specific application. Make sure
		appropriate over temperature, safety devices and other
		precautions are included in the system, process, or product design.

	3.9  	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 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.
