UNPACKING:
Carefully unpack and remove the furnace from its shipping carton. Save the carton and other packing material for future
use in transporting the furnace.
Shipping damage should be reported to the carrier as soon as detected.
LIFTING AND CARRYING:
NOTE: The 1750 models require two people.
• Get a firm footing. Keep your feet shoulder width apart for a stable base.
• Bend your knees. Don’t bend at the waist.
• Grip the base of the furnace and lift with your legs.
DO NOT LIFT FURNACE BY THE TOP MUFFLE ASSEMBLY!
• Keep the load close to your body and carry the unit to the destination. Keep your back upright during lifting.
The shipping carton contains the following:
• One furnace complete w/ power cord • Owner & Operator’s Manual
• Ceramic floor tray (shipped in the muffle) • Muffle shelf (Model 1750 only)
• Auxiliary switch (Model 3-550PD only)
• Exhaust port ball plug (for heat treating applications only)
INSTALLATION:
1. Remove all packing material from in and around the furnace. The furnace should be located at least 15cm (6”) away
from walls, shelves, and heat sensitive materials. Open the furnace door and remove the packing material from inside
the furnace.
NOTE: The furnace front panel may show some discoloration around the muffle due to the calibration and burning
cycles performed at the factory.
2. The furnace should not be located directly under shelves and other airflow restrictions.
3. On high voltage (200-240 volt) units, connect the power cord to the socket in rear of furnace. (this applies to 550A
only, 1750A cord is already connected).
4. Positioning the furnace:
a) (Combustion, Burnout or Reaction Processes) Position the furnace under a vent hood or connect the exhaust port to
a ventilation system to prevent exposure to the exhaust fumes. The furnace exhaust port 25 mm (1”) OD by 25 mm (1”)
long [50 mm (2”) OD by 20 mm (0.8”) long on 1750 Model] can be ducted into the exhaust hood for more effective
ventilation. Stainless Steel flexible metal tubing can be used for this ducting.
b) (Heat Treating or Non-Reaction Processes) Position the furnace under a vent hood. Plug the exhaust port with the
ball plugs provided in the furnace accessory kit. This will reduce heat loss and electricity requirements.
5. Connect the furnace to a power circuit or receptacle with an overcurrent protection (circuit breaker or fuse) rating of 20
Amps on the low voltage model and 10 Amps on the high voltage model. This circuit should only supply the furnace.
The 1750 North American model requires a 20A supply (breaker/receptacle). The 1750 European model requires a
dedicated 32A supply breaker/receptacle).
6. (3-550PD only) Plug the auxillary switch cord into the two prong socket located next to the power cord/socket.
7. Turn on the furnace’s green power switch (right-hand side of the control panel) and the CD display will come on. The
light in the green power switch lights when the door is closed and the start key is pressed.
8. At this time, your new furnace should be ready to operate. Please review the OPERATIONS and SETUP & MAINTENANCE
sections of the manual before proceeding to select special options.

OPERATING INSTRUCTIONS:
RUNNING A PROGRAM:
The furnace has 9 three stage programs and one single temperature hold program. The furnace is sold with the program
parameters set to the factory defaults which can be used for testing. First time operation will require the user to enter
their desired parameters into one of these programs.
1. Turn on green power switch (right-hand side of control panel)
After a short delay for internal testing, the furnace will display approximate room temperature, program time
(hours:minutes), and program number. All red EDs are off. (If any of the EDs are on, the furnace was already running
a program when it was last turned off.)
2. Select or change the program to the desired number by pressing the digit key (1-9) for the desired program followed by
the ENTER key. The display will be updated to show the new program number and its approximate run time.
3. Pressing the green Start key will start this program. The red EDs will come on and the time will start to count
down. The green power switch will light when the door is closed. The EDs will be turned off as each segment of each
stage of the program is completed.
• During program operation, the total program cycle time is counting down as indicated by the flashing colon in
the time.
• If a program is started when the muffle is already heated, the furnace will heat or cool at the first ramp rate to
the first temperature from the current muffle temperature. It will not cool to room temperature before starting.
• The program will end by maintaining the last muffle temperature, displaying “Hold”, beeping every 3 seconds
and flashing the last Temp ED. See information on End Of Program options (point 1) in the “Setup &
Maintenance” section if other operations are preferred.
4. Pressing the key will change the temperature display from °C to °F and back. This key is not active during
parameter programming.
5. A short power outage during the operation of a program will not terminate or abort the program unless the muffle
temperature drops more than 32°C (58°F). If the power outage occurs when the muffle temperature is close to, or at
room temperature (e.g. during Delay Start operation) the furnace will continue the program when power is restored
regardless of the temperature drop or the amount of time that has expired.
6. Pressing the Escape key cancels beeping at the end of a program. It also will return the furnace to a display of
the current conditions during programming operations.
7. Opening the door during a cycle interrupts power to the heating elements.
STOPPING A PROGRAM:
1. Pressing the red Stop key will stop the program that is currently running. The red EDs will go out and the
display will show the current program number, approximate cycle time, and the current muffle temperature.
PROGRAMMING:
The furnace increases productivity and reliability for the operator because cycles or programs can be preprogrammed and
operated automatically. Once programmed, the parameters are retained in memory even with the loss of power.
Parameters are not retained in memory if entered during the operation of a program.
Each program is made up of 3 stages which require 3 parameters each. The parameters are grouped into ramp rates (R1,
R2, R3), temperatures (T1, T2, T3), and dwell or hold times (H1, H2, H3). The 1,2,3 indicates the stage number or
sequence. The temperatures can be programmed in either °C or °F; the ramp rates in °C per minute or °F per minute; and
the hold times in hours and minutes (hh:mm).
RAMP RATES (R) (0 - 40°C/minute)
1. Pressing the Rate key makes the display show the current value of the R1 parameter followed by 3 blanks for a
new value.
• For example: R1 8.0°C/M ->_ _ _
• The corresponding ED will also light to indicate the selected stage and parameter.
2. Use the digit keys (0,1,2,...,9) to enter the desired parameter value followed by the ENTER key. The new
parameter is now stored in memory.
• If a value is entered that is out of the acceptable range, the furnace will beep and display the acceptable range.
• Programming a Rate to 0 will cause the furnace to terminate the remainder of the program stages. For example, if R2
is set equal to 0 then at the end of the first hold time (H1) the furnace will go to the end of the program, making the
S

program single stage.
3. Pressing the Rate key additional times will display and give access to the Rate parameters for the other two
stages. The 4th time the key is pressed the display circulates back to the beginning and the R1 parameter will be
displayed again.
• The Rate key operates the same if pressed during the operation of a program with the following exception.
The new Rate entered is used only for that one program or cycle and not stored in memory.
• Negative ramp rates are also possible if slower than natural cooling.
TEMPERATURES (T) (50 - 1100°C or Tmax)
1. Pressing the Temp key makes the display show the current value of the T1 parameter followed by 4 blanks for a
new value.
• For example: T1 160°C ->_ _ _ _
• The corresponding ED will also light to indicate the selected stage and parameter.
2. Use the digit keys (0,1,2,...,9) to enter the desired parameter value followed by the ENTER key. The new
parameter is now stored in memory.
• If a value is entered that is out of the acceptable range the furnace will beep and display the acceptable range.
3. Pressing the Temp key additional times will display and give access to the Temp parameters for the other two
stages. The 4th time the key is pressed the display circulates back to the beginning and the T1 parameter will be
displayed again.
• The Temp key operates the same if pressed during the operation of a program with the following exception.
Any new parameter entered is used only for that one program or cycle and not stored in memory.
HO D TIMES (H) (0 - 99:59 hh:mm)
1. Pressing the Hold key makes the display show the current value of the H1 parameter followed by 4 blanks for a
new value.
• For example: H1 1:00H ->_ _ : _ _ (1 hours and 00 minutes)
• The corresponding ED will also light to indicate the selected stage and parameter.
2. Use the digit keys (0,1,2,...,9) to enter the desired parameter value up to 99 minutes and 59 seconds followed by the
ENTER key. The new parameter is now stored in memory.
3. Pressing the Hold key additional times will display and give access to the Hold parameters for the other two
stages. The 4th time the key is pressed the display circulates back to the beginning and the H1 parameter will be
displayed again.
• The Hold key operates the same if pressed during the operation of a program with the following exception.
Any new parameter entered is used only for that one program or cycle and not stored in memory.
AIR EXCHANGE OPERATION
1. The air exchange operation is accomplished by using the venturi principle to draw air out of the muffle and into an
exhaust air flow. The hot muffle air does not pass through the fan. Make up air for the muffle is introduced behind the
muffle heating plates. This indirect air path causes the make up air to preheat before it reaches the muffle cavity to
assure temperature uniformity.
2. The air exchange fan produces about 20CFM of flow when operated at full speed. The vent hood or system being used
for the furnace should have sufficient capacity to accommodate this airflow.
3. The air exchange operation may be controlled for 10 different settings, ranging from 0 to 9 (off to full on). The
maximum setting of 9 on the control performs approximate 5 air exchanges per minute. The curves shown on page 13
show approximate air changes vs. fan setting.
Example: Stage 1 of program 5 can be programmed to a fan setting of 9 while stage 2 of program 5 can be programmed to
a fan setting of 3 and stage 3 of program 5 to a fan setting of 0 (off).
4. The air control settings are retained in memory for each program even when the power is removed.
5. The air control settings are programmed into memory the same way as other parameters. Change to the program

number of interest, press the key: once for stage 1, twice for stage 2 and three times for stage 3. The display
shows the current fan level and a new level may be programmed.
A fan speed setting is changed and stored by pressing a digit key (0-9) followed by the ENTER key. A fan setting
change made while a program is operating (running) is only used during that cycle and is not saved in permanent
memory.
The higher the air control setting the slower the furnace will heat. High air control settings with low line voltages may
prevent the furnace from reaching the maximum temperature.
PROGRAM 0
Program 0 is a single temperature hold program. The furnace will heat to this temperature and maintain it as long as
power is applied.
1. Press the 0 key. The display shows the current programmed temperature and the 0 program number.
2. For example: T0 100°C -> _ _ _ _
3. Use the digit keys (0,1,2,...9) to enter the desired temperature followed by the ENTER key. The new parameter
is now stored in memory after 3 seconds. The display shows: 100°C ***** 0 where 100 is the current muffle
temperature, 0 the program number, and ***** indicates that the program is not started.
4. Pressing the Start key will cause the furnace to heat at full power to the programmed temperature. The display
will show “xxxx°C *Hold* 0” “xxxx” is the current muffle temperature, the word “Hold” illustrates single stage and 0
for the program number. The T1 ED will also be on.
SPECIA FEATURES
DE AY START (D)
The Delay Start functions as a timer that automatically starts a program so that it is completed at a selected time up to 7
days later. The delay is programmed in terms of the number of delay days and the desired completion time. The furnace
uses a clock to keep track of time when the furnace power switch is on. If a power outage should occur during a “Delay
Start”, the completion time will be delayed by the length of time the power was off.
Programming The Delay Start:
1. Pressing the Delay Start key makes the display show the current value of the time of day and beep.
• For example: Now = 7:30 -> _ _:_ _
• The corresponding ED will also light to indicate the Delay Start is selected.
2. Use the digit keys (0,1,2,...,9) to enter the current time of day followed by the ENTER key. The new parameter is
now stored in memory. The time of day must be entered in as a 24 hour clock (11:34PM is 23:34), (8:10AM is 08:10).
• Programming the current clock time “Now = 7:30 -> _ _:_ _” is only displayed and requested if there has been a power
outage since the last time the Delay Start was operated Turning the power switch off stops the internal delay start
timer.
3. Pressing the Delay Start key again makes the display show the current value of the Delay D parameter in days.
• For example: Day: 1 [1,2,...,7]
• The corresponding ED will also light to indicate the Delay Start is selected.
4. Use the digit keys (0,1,2,...,7) to enter the desired number of days of delay followed by the ENTER key. The
new parameter is now stored in memory.
• If a value is entered that is greater than 7, then the furnace will display and use 7.
5. Pressing the Delay Start key again displays the program completion time. The furnace will calculate the
approximate time that the program needs to start so that it is completed by the programmed time.
• For example: End = 8:00 -> _ _ :_ _
• The computer uses a 24 hour clock. For example if 14:30 is programmed, the completion time is 2:30 PM.
6. Pressing the Delay Start key again will show the actual time (Now).
• Pressing the key additional times will cycle through the other parameters. Press the Escape key to stop the
function.

program can be run automatically. Additional programs can also be linked as each program is completed.
Running inked Programs:
1. Press the green Start key with the first program to be run. The furnace will start operation.
2. Use the digit keys (1,2,...,9) to enter the next program number to be run followed by the ENTER key. The furnace
will now run the first program followed automatically by the second. The program cycle time on the display will be the
combination of the two programs. The display will alternately show the first program and then the second program
number will be displayed for a shorter time.
POWER DOOR (3-550PD only)
The remote activation switch is used to operate the power door. Activating the switch once, will cause the door to open or
close. Activating the switch while the door is moving will cause the door to stop. Once stopped, activating the switch
again will cause it to reverse directions.
The furnace will also automatically close the door after a programmed amount of time during a firing cycle. This feature is
disabled at the factory and needs to be activated to operate. See Setup, page 11 for instructions.

SETUP:
The Vulcan furnace goes through a self test that lasts for 4 to 6 seconds each time that power is applied. After the test,
the display will show the word “SETUP?” for approximately 5 seconds. In the Setup mode, several different options are
available for the user to select.
The first is the END OF PROGRAM operation which allows the user to select how the furnace should operate at the end of
the program. The second is the TMAX parameter which limits the maximum temperature that can be programmed into the
furnace. The last is TEMPERATURE ADJUSTMENT/CA IBRATION which allows the user to alter the furnace temperature
calibration.
1. Turn on power to the furnace. Pressing the ENTER key when the word “Setup?” is being displayed will start the
Setup mode first with the End of Program options.
• The current END OF PROGRAM option is now displayed as “Hold = 1 (2),(3)”. The (1) option is the factory default. It
will cause the furnace to maintain or hold the last programmed temperature, display “Hold” and beep every 3
seconds until the red Stop key is pressed. Pressing the Escape key will stop the beeping but not the
program.
• The (2) option will cause the furnace to maintain or hold the last programmed temperature, and display “Hold” but
without beeping until the red Stop key is pressed.
• The (3) option will cause the furnace to turn off and cool to room temperature at the end of the program and display
“End”. The Stop key does not have to be pressed.
• Use the digit keys (1,2,3) to change the END OF PROGRAM option.
2. Pressing the ENTER key when the desired End Of Program is selected will store it in memory and then advance
to TMAX which is the next option. The TMAX value limits the maximum temperatures that the furnace can be
programmed to or fire to. The factory setting for TMAX is 1100°C. Use the digit keys (0,1,2,...,9) to enter the desired
TMAX value followed by the ENTER key. The new Maximum Temperature is now stored in memory and the next
option is displayed.
3. 3-550PD only) The automatic closing portion of the Power Door feature is shipped from the factory in the disabled
condition of 0 (Door 0sec-->). A delay time before closing of 1 to 99 seconds can be entered to activate the auto
closing. The automatic closing is only active during firing cycles.
4. The final option is the temperature adjustment/calibration which is displayed as “Tcal 1000°C->_ _:_ _”. The factory
setting for Tcal is 1000°C. Use the digit keys (0,1,2,...,9) to enter the desired Tcal value followed by the ENTER
key. The new Temperature Calibration is now stored in memory. Entering a 1000 will return the furnace to the factory
calibration. See the next section on Temperature Adjustment/Calibration for specifics on how to determine the
adjustment number.
TEMPERATURE ADJUSTMENT/CALIBRATION:
Every VU CAN furnace is calibrated in the factory at 1000°C. Under normal use the furnace should not require calibration.
The electronics used in the VU CAN furnaces are very stable and will have minimal drifts over the life of the furnace.
Thermocouple replacement could be a potential requirement for calibration if high accuracy is required.
This calibration can be altered by entering a new Tcal value in the Setup mode listed previously. The Tcal value has a
range of 900 to 1100°C.
For example: A program is operating at a stable temperature and a separate thermocouple is inserted in the furnace and a
digital thermometer measures the muffle temperature. The display shows 875°C which is the programmed temperature
but the digital thermometer reads 868°C. A new calibration value could be calculated by dividing the display temperature
by the actual temperature (digital thermometer) and then multiplying by the current Tcal value (factory default is 1000°C).
In this case the result is 1008 (875/868 = 1.008; 1.008 * 1000 = 1008). 1008 is entered in as the Tcal value. With this
method the furnace calibration can be done at the normal operation temperature.
Second example: Programmed temperature is 1050°C and the digital thermometer reads 1065°C. The old Tcal value is
985°C.
(1050/1065 = 0.986 then 0.986 * 985 = 971) 971 should be entered as the new Tcal value.
CLEANING:
• Vacuum dust and dirt from the furnace rather than attempting to blow the dust off. This will minimize the amount of air
born particles.
• Use a soft damp cloth to clean the control panel. Avoid excess water or solution when cleaning the furnace. These
solutions can attack the panel or electronics and cause the furnace to malfunction.

TROUBLESHOOTING THE ULCAN 3-SERIES FURNACE
TROUBLESHOOTING:
PROB EM CHECK IST / CAUSES
Dead, Not Operating - Check power receptacle or outlet for power.
No Power / Display - Check line or power cord connections.
- Turn on green power switch.
- Check fuse (20 amp) and lamp on control PDB.
Not Heating During Program - Is door completely closed? Door switch may be interrupting power.
Operation - Check heating element plates for continuity.
Door Too oose or Tight - The amount of force or drag on the door movement can be changed by adjusting the
hex screws (both sides should be adjusted equally) located on the upper rear corners
of the furnace cabinet. Turning the screw clockwise adds drag and requires more
force.
Heating Too Slow - Rate programmed wrong. 1.5°/minute rather than 15.0°/minute.
- arge loads will slow down response time and increase the time to temperature by 2
to 5 times.
- Muffle near end of life.
Program Turns Off Too Early - Programming a Rate to zero will terminate the remainder of the program.
- End of program option has been changed from 1 or 2 to option 3 which turns off the
furnace at the end of the program [End].
Power Door Does Not Open - A hidden switch to activate the door is located between the °C/°F key and the Delay
(3-550PD only) Start key. Try pressing it to test the operation.
- Check activation switch connections to back of furnace.
- Allow the furnace to cool and test the door by activating the switch and then lifting
up/pushing door on the door in the appropriate direction of travel.
Fan Does Not Operate - Operates only in a start cycle
(Air Exchange Model Only) - Setting of 0 means no fan active
