!
• Never operate furnace in close proximity to combustible materials or place
materials on top of the furnace.
• Caution: To provide continued protection against risk of electric shock,
connect to properly grounded outlet only.
• The furnace must be electrically grounded to a three wire electrical outlet or
receptacle. The electrical service provided must be a dedicated line of the
proper size according to local electrical codes.
• Disconnect the line cord before attempting to service the furnace.
• Do not attempt to service the furnace until you read and understand the
service manual. (See Service Manual under Accessories on page 11)
• Do not operate the furnace controls with tongs or other tools; the tongs will
damage the control switches.
• Do not use solvents or liquid cleaners on the control panel; they will enter the
panel and damage it.
• Do not place firing trays or other hot objects directly in front of the furnace; they
will melt the graphic overlay.
• Always verify that the power switch light is off before attempting to load or
reach into the furnace chamber with any tools or instruments.
• As a routine working precaution, always wear safety glasses and protective
gloves when operating, loading and unloading the furnace.
• The furnace is not equipped with overcurrent protection on the AC primary. In
the event that an overcurrent condition occurs, the building's branch circuit
overcurrent protection (fuse or circuit breaker) will be the primary means of
protection.
OSHA AND CALIFORNIA PROPOSITION 65: MUFFLE DUST EXPOSURE
In keeping with the policy of Degussa-Ney Dental Inc. to build safe products, comply with all
National and State statutes and keep you, the valued customer informed; the services of a
Certified Industrial Hygienist firm were employed to test and evaluate the lab operator’s
exposure to respirable refractory ceramic fiber (RCF) and crystobalite (a form of crystalline
silica) present in the furnace muffle.
The findings of this test revealed that levels of exposure during the normal operation of this
equipment, as outlined in the operator’s manual, were far less than the Permissible Exposure
Limit set by the Federal Government.
When it becomes necessary to replace the muffle, the person doing this work is recommended
to wear a HEPA filter respirator and protective gloves as a precautionary matter.
Seal used muffle in a plastic bag and dispose of in accordance with local, state and Federal
regulations.
Because this product and many similar products on the market today contain crystalline silica
and ceramic fibers, it is necessary under the statutes of California Proposition 65 that
Degussa-Ney Dental Inc. include the following statement:
“This product contains substance(s) known to the State of California to cause cancer.”
Material Safety Data Sheets for RCF materials supplied upon request.
Canadian Standards Association (CSA) and TÜV Product Service GS
certified.

CHECK LIST / CAUSES
Does the green power switch light?
No: - Check power receptacle or outlet for power.
- Check line or power cord connections.
- Check door that it is completely closed.
Door switch may be interrupting power.
Yes: - Check the control knob and verify that it is
turned to desired temperature.
- Check the fuse on the controller PCB.
- Check heating element plates for continuity.
- If muffle is hot but the meter reads a low
temperature check the thermocouple for
shorts to the cabinet.
The control will slowly approach the setpoint
temperature. Set to a higher temp and then turn
down to reduce the heatup time.
On the low voltage model (100-125VAC) the
heating element plates are wired in parallel. If one
plate fails the furnace will heat very slowly and not
reach the setpoint temperature.
Slight changes in the knob rotation will have a
significant impact on the setpoint temperature. If
major differences exist between the meter and the
knob scale a temperature adjustment can be make
as described on page 9 "Temperature Adjustment".
The amount of force or drag on the door movement can be changed by adjusting the hex screws
located on the upper rear corners of the furnace
cabinet. Turning the screw clockwise adds drag
and requires more force.

INSTALLATION INSTRUCTIONS
UNPACKING:
CAUTION:
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.

TEMPERATURE ADJUSTMENT:
Every
VULCAN furnace is calibrated in the factory at 1100°C.
CAUTION! Unplug the power cord before attempting to adjust the
calibration. The Thermocouple and PC board are connected to the AC
power supply!
The calibration can be adjusted by turning the trimmer potentiometer (pot) RP1
located on the "A" Controller board. If the meter temperature is lower than the
temperature setting that the control knob is set to, turn the trimmer pot one 1/4 turn
clockwise. If the temperature is higher then a 1/4 turn counter clockwise. Allow
the furnace 10 to 20 minutes to stabilize before making further adjustments.
CLEANING:
• Vacuum dust and dirt from the furnace rather than blow. This will minimize the
amount of air born dust 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.

The furnace shipping carton contains the following:
- One furnace complete with power cord
- Owner's & Operator's Manual plus Calibration Pellets
- Ceramic Floor tray (shipped in the muffle)
- Two exhaust port plugs (for heat treating applications only)
LIFTING AND CARRYING:
NOTE: The 1750 models require two people.
1 Get a firm footing. Keep your feet shoulder width apart for a stable base.
2. Bend your knees. Don't bend at the waist.
3. Grip the base of the furnace and lift with your legs.
4. Keep the load close to your body and carry the unit to the destination. Keep your
back upright during lifting.
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 will show some discoloration
around the muffle due to the calibration and burnin cycles performed at the
factory.
2. The furnace should not be located directly under shelves and other airflow
restrictions.
3. On high voltage (200-250 volt) units, connect the line cord packaged in the rear
of the furnace to the socket in rear of furnace.
4a (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.
4b (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. The furnace should be the only load on this circuit.
The 1750 North American model requires a 20A supply (breaker/recepticle).
The 1750 Euro model requires a dedicated 32A supply (breaker/recepticle).
6. Turn on the furnace lighted green power switch (right-hand side of the control
panel).
7. When the door is fully closed, the power switch light should be illuminated. As
the door opens the power switch light should turn off. Do not attempt to operate
the furnace if this light does not turn off when the door is open.
8. At this time, your new furnace should be set-up to operate. Please review the
Operations section of the manual before proceeding to operate the furnace.

OPERATIONS
STARTING OPERATION:
Close the furnace door. Turn the green power switch to the on (I) position. The light inside the switch will turn on. An interlock door switch
located inside the furnace disconnects the power to the muffle when the
door is opened. The door must be closed for the furnace to heat.
Turn the setpoint knob to desired temperature and the furnace will ramp
to the set temperature. Turn off the power switch, to turn off the furnace.
The temperature rate will start out at full speed and gradually slow as it
approaches the setpoint temperature. If a slower temperature increase
rate is required set the temperature at several intermediate temperatures.
This will cause the control to approach each intermediate temperature at
a slower rate.
Note: Observe the rate curves on Pg.6-7 to determine the time required
to reach set-point.
OPERATING EXAMPLES:
The furnace will continuously operate at 900°C each day.
- Insert work, close door, adjust knob to 900°C (white inside scale).
- Turn power switch to on position (green light should come on when
door is down). If the same temperature is needed each day the knob
does not have to be adjusted.
- The furnace will heat to the temperature indicated on the front control
panel. Turn off the power switch when the cycle is finished.
A temperature cycle calls for a slow ramp to 700°C (1300°F).
Procedure:
- Insert work and close door.
- Turn power switch to on position (green light should come on when
door is down).
- Turn the set-point knob to 300°C (inside scale), 30 minutes later turn
the knob to 500°C, and finally 30 minutes later to 700°C .
- The furnace load slowly heats to the desired 700°C.
Note: Because of the nature of the control, the first 90% of the rate will
be relatively fast while the last 10% takes somewhat longer. The
furnace will reach the set point, but it takes some time. If a faster
rate is required, set the furnace to approximately 10 to 20% higher
than desired set-point and then adjust to the desired set-point when
temperature is reached.
