Operating Instructions

Unpacking: Check unit for damage. Do not operate this unit if damaged.

1. Inspect Vulcan and the power cord for any damages before using. Do not use the system or the cords if damaged. Read Caution statement.
2. Locate the unit in safe DRY area. See WARNINGS and CAUTIONS on page 2.
3. Turn all heater switches OFF and Temperature Control switch to MAN.
4. Plug your unit into 230VAC/1 phase, 30 or 50 amp power supply. POWER light will come ON.
5. Note: Use only power source with ground and over-current protection. Recommended EDPCORDKIT: Dryer/Range, 4 prong, 8’ 6/3-8/1 125/250VAC 30/50 Amp plug.
6. Turn AIRFLOW controller knob from OFF to your required speed and the AIRFLOW status light will turn ON.
7. When AIRFLOW light is on and internal heater temperature is less than 180° F, the SAFETY light will turn ON.
8. Turn ON the individual heating elements, starting with #1. For 30 amp power supply only #1, 2 & 3 elements (20,500 BTU) can be ON. For 50 amps, all 6 heaters (37,000 BTU) can be turned ON.

Temperature Control

Auto
Switch the temperature control switch to the AUTO position. On Temperature Controller, use up/down arrows to set the desired temperature Set Point (SP) up to 160° F. Locate the thermocouple end in the measured area or targeted material. The Temperature Controller will display the measured temperature and selected set point SP. When SP temperature is reached, Temperature Controller will turn the heating elements Off and automatically restart when the temperature drops 10° F below the SP. Change your SP as needed at any time.
After the heater stabilizes at your required temperature, check the operation of the heating elements. If the Temperature Controller is frequently turning the heaters OFF/ON, reduce the number of active heaters or increase the airflow.

Manual
The Temperature Control switch should be in the MAN position. To regulate the heater temp., activate only the number of heating elements required for the heat rise. Increasing airflow will decrease the exhaust air temperature.

The internal heater temperature is limited to 160° F. When this high limit is reached, thermo switch TS-2 turns all active heaters off and automatically restarts at 135° F. Note: The exhausted air temp. may be considerably higher than 160°F.

If the 160°F thermo switch is frequently turning the heaters OFF/ON, reduce the number of heating elements or increase
the airflow to stay below 160° F.

Shut Down Procedure

The heat energy stored in the heating elements could heat up the outer surface of the unit if it is shut down without any cooling down period. To prevent this and to maximize the life of the heating elements, follow this procedure:

1. Place into manual mode, and switch all heating elements to OFF position
2. Allow the blower to run for at least five minutes or until airflow has cooled
3. Switch the blower to OFF position
4. Disconnect cords and store the unit

Operation Tips

For the Vulcan model, ensure the thermocouple is plugged into the unit before powering on. For the Vulcan RT model, ensure the remote is plugged into the unit before powering on.

• To minimize the On and Off cycling of the heaters, balance the airflow and the number of active heaters by watching the heater switch lights to see the ON/OFF operation.
• The temperature Safety switch will turn the heaters Off and ON between 180° and 150° F. This is a safety cutoff and heater should not operate this hot.
• When the safety switch shuts the heaters down, the SAFETY light also turns off.
• When the internal heater temperature reaches 160° F limit, the exhaust air temperature would be around 180° F. Take this in consideration when ducting hot air to a remote containment area.
• Vulcan delivers up to 37,000 BTU and at 400 cfm of air flow at temperatures from ambient to 160° F. The heater outlet can be ducted to deliver heat where needed. The air intake could be open to ambient air or ducted from a dehumidifier.
• At an airflow of 350 cfm, operating with all 6 heaters, the temperature rise is 95° F above the ambient air. When operating on 30 amp circuit with 3 heaters, the temperature rise is 55° F. At lower airflow, the heat rise will be higher. At 475 cfm, the heat rise is 75° F with 6 elements on.
• Vulcan is designed for indoor use only and it is important to locate the heater in dry, safe location. The heater exhaust must be 3 feet or more from a wall or any soft material.
• When ducting hot air to a remote area, using a shorter duct reduces heat losses.
• Please read the Safety warnings before starting to operate your new Vulcan.
• The unit may be operated in a horizontal or upright position with the exhaust aimed up. Do NOT lay the unit on air intake side or block the outlet.
• The Heater must be plugged into a 250 VAC power supply equipped with over-current protection. The heater unit blower must be running before the safety interlock circuit enables the heater elements to be turned on. Depending on the 30 or 50-amp power supply, 3 or 6 heating elements can be selected. Since there are many variables from project to project, we recommend setting your airflow first and then starting to turn the heating elements on. Depending on your ambient temperature, selected airflow and required temperature rise, the number of operating heating elements will vary.
• The Vulcan offers maximum versatility with variable airflow and 6 heating elements which can be individually turned on as needed. After manually setting the airflow and number of heating elements, the heater temperature could be regulated in
• MAN (Manual) or AUTO mode. In MAN, the High-temperature switch is set to shut off heating elements when the internal heater temperature is 160º F and restart at 135º F.
• In AUTO mode the Temperature Controller measures remote air or material temperature with a thermocouple connected to the temperature controller.
• The measured temperature is compared with the selected Set Point which cannot be higher than 160° F. Temperature Controller automatically turns selected heating elements on and off to maintain the set point.
• The Safety circuit protects the unit from overheating. If the heater loses a minimum required airflow, all the heaters will shut down until the airflow is restored. Also, if the internal heater temperature reaches 160° F, the safety thermo switch TS-1 shuts the heating element down and restarts automatically at 150° F.
• Electrical Requirements: Vulcan unit requires 250 VAC/ 1 Phase power source with over-current protection rated at 50 amp maximum. It can be plugged into a dryer/range outlet, or generator, or hardwired into an electrical panel by a certified
  electrician. The amperage draw will depend on the number of elements engaged. Each element draws
  about 8 amps. For maximum heat gain, use all 6 heating elements.
  Note: The heater can operate on 208 VAC at reduced heat output.

Operator’s Controls

1. On the Vulcan model, airflow is controlled by changing the speed of the blower. Turn the control knob from OFF to anywhere on the dial and check that the AIRFLOW light turns ON. On the Vulcan RT model, airflow is a fixed speed when the unit is on.
2. The digital hour meter measures the cumulative time the unit is running to tenths of an hour. It stores and displays the total time when the unit is disconnected from the power supply.
3. Temperature Controller displays measured temperature, Set Point, and provides automatic ON/OFF heaters control. Temperature Controller is programmed to maintain user-selected set point temperature when AUTO mode is selected and the remote thermocouple is connected to the thermocouple on the control panel (figure 1 point 4). Place the sensor end in the containment area to monitor air or materials temperature to prevent overheating delicate parts of the structure.
4. Thermocouple connector for K-type sensor
5. Temperature Control mode selector switch with MAN/AUTO positions.
6. Heaters switch 1 to 6 – ON/OFF switch with internal light. Lights illuminate as each heating element is activated. If the element is not activated, the switch light will not be illuminated.
7. The blower speed controller with OFF and Max provides adjustable airflow settings.
8. Temperature Controller Plug (for remote control), remotely displays measured temperature and provides automatic ON/OFF heaters control.

Status lights

• POWER – Red light indicates power to the unit is On.
• AIRFLOW – Amber light indicates the blower is operating and the airflow switch is closed.
• SAFETY– Amber light indicates the air flow is safe and the heater internal temperature is below 180° F. HEATER ELEMENTS – Each heating element switch illuminates when switched ON and active.

Maintenance of the Vulcan

The blower and motor do not require any maintenance when the heater is operated with MERV 11 filter in place. Replace filter as needed. If filter becomes clogged with debris it will reduce the performance of the unit.

• ALWAYS UNPLUG FROM POWER BEFORE OPENING THE UNIT.
• ALWAYS FOLLOW YOUR ESTABLISHED HAZMAT PROCEDURES.

Troubleshooting

This guide may identify easy-to-correct problems in Vulcan operation and does not require opening the unit. Only a qualified maintenance person should replace internal heater parts. The removable control panel provides easy access to panel-mounted components. The heating elements and the blower motor can be accessed by removing the cover panels on the bottom.
Note: Start testing with the Temperature Control switch in the MAN position. The POWER (red) light does not come on when plugged in 230
Vac/1 ph power

1. Check the power supply source and the extension cords are in good working condition and providing 230V.

The blower is running, but the AIRFLOW light is off

1. Increase the blower speed until the AIRFLOW light comes on – if no AIRFLOW light comes on and contractors do not energize ( loud click), the problem could be a faulty air flow switch.

The blower is running, AIRFLOW light is on but the SAFETY light is off while the heater is cool.

1. TS-1 Safety thermo switch needs to be checked. It is set to open at 180° F and close again at 150 F.
   The blower is running, AIRFLOW and SAFETY lights are on, but contractors do not click on (heater switches do not illuminate when switched ON)

Both contractors are energized, but some heater switches do not illuminate when selected. Note: Contactor #1 controls heater elements 1, 2, and 3; Contactor #2 controls heater elements 4, 5 and 6.

1. Turn ON one heater at a time to check each heater circuit. The heater switch will illuminate when the heater is turned on and functioning.
2. Check the heater output for the temperature rise.
3. If the selected heater switch does not illuminate, the problem could be a faulty heater switch or heating element.

The heater is frequently cycling ON and OFF as the High-temperature switch operates between 160° and 135° F. Watch heaters switch lights for cycling frequency.

1. Reduce the number of heating elements turned ON.
2. Increase airflow.
3. Check for obstacles on the suction and discharge side. This could be dirty filter or a long ducting.

Temperature Controller in AUTO mode Temperature Controller (TC) will display the temperature measured by the thermocouple
all the time, but only in AUTO mode will it use the measured temperature and the set point (SP) temperature to control the heaters. When SP is reached, the heaters are turned off till the temperature drops 15° F below SP, then turned on again. The SP temperature can be adjusted with Up/Down arrows at any time.

NOTE: The programming functions on Temperature Controller are locked to prevent unauthorized program changes. See the programming section of the manual to unlock, reset or change the program.3. Check for obstacles on the suction and discharge sides. This could be a dirty filter or a long ducting.

The heater works when the Temperature Control switch is in MAN but the heaters turn off when TC controls the heaters in AUTO.

1. The thermocouple must be plugged in for TC to operate. If the display reads NO CONT., the thermocouple could be faulty.
2. The SP temperature must be set a minimum of 15° above the temperature measured by the thermocouple for heaters to turn on – use Up/Down arrows to change the SP.
   NOTE: High temp. limit switch shuts down the heater at 160° F internal temperature even if SP calls for more heat.
