OSHA AND CALIFORNIA PROPOSITION 65:
MUFFLE DUST EXPOSURE
In keeping with the policy of DENTSPLY NeyTech 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.
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 DENTSPLY NeyTech include the
following statement:
“This product contains substance(s) known to the State of California to cause cancer.”

INSTALLATION INSTRUCTIONS:
FEATURES:

S
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.
2. The furnace should not be located directly under shelves or other airflow restrictions.
3. Vacuum pump connections:
ELECTRIC VACUUM PUMP CONNECTIONS:
From the rear of the furnace connect the vacuum pump's tubing to point Band plug the pump's power cord
into the socket at point A.
4. Connect the furnace to a power circuit or receptacle with an overcurrent protection (circuit breaker or fuse)
rating of at least 15 Amps. This circuit should only supply the furnace and pump.
5. Turn on the furnace power switch (right-hand side of the control panel).
6. FIRST TIME ONLY: After the initial power up the display will show: "Remove Foam!", "Place Insulation",
"Muffle is off", "To Operate: <ESC>". The muffle will open and the display will again display this sequence.
Pressing the ESCkey will start normal operation.
7. The furnace display will show "Nite Mode" after approximately 8 to 10 seconds of self test.
If the operation of the furnace causes the lights to "blink" or "flicker" the furnace is on the same circuit
breaker or fuse as the lighting.
8. IMPORTANT! Open up furnace with muffle movement keys located on lower left side if the furnace does
not open automatically. Install ceramic work platform ("Place Insulation").
Operating the furnace without this platform will damage the furnace!
9. Press ESCkey followed by the green start key in the upper right corner of the control panel.
Program 50 will now run to remove any accumulated moisture. This program will take approximately 30
minutes.
If the furnace does not pull vacuum "Err4" check the following:
• Verify that the ceramic work platform is centered on the door.
• Check the vacuum pump to verify that it is energized.
• Check the vacuum hose connections to verify that they are connected to the correct locations.
• Check door o-ring seal for contamination, and remove with clean rag.
If the furnace pulls a low vacuum "Err5" there may be moisture in the muffle. Press the ESCkey and
allow the furnace to continue running to remove the moisture.
10. Daily Use: Before starting the normal firing process each day allow the furnace to preheat for 15 to 30
minutes at its low temperature. Alternately, running a firing cycle without a load can also be used as a
preheat operation. Preheating the furnace will provide more accurate and consistent results.
When the furnace is not being used keep the muffle closed. This prevents the absorption of moisture into the
thermal insulation which reduces vacuum levels when normal firing is attempted.

not affect the length of time the muffle is held at the "Hi T".
SPECIAL OPERATIONS:
NEXT STEP - Pressing the key during a firing cycle will cause the control to end the current cycle
segment. (e.g. Rate > Hold > Cool) Pressing this key during the Cool segment will cause thefurnace to
repeat the last cycle starting with the Rate.
ESC - Pressing the keyduringprogrammingwill return the furnacetotheIDLE MODE or FIRINGCYCLE
MODE if the furnace was running a cycle.
NITE - Pressing the key will cause the furnace to go into NITE MODE if the furnace is in IDLE MODE.
The furnace will cool down to 100°C then the muffle will close.
Press the ESCkey to cancel the NITE MODE operation.
NITE (Firing Cycle) - Pressing the key during a firing cycle will cause the control to enter the Nite
Mode after the completion of the firing cycle and the LCD shows “Nite Mode”.
MUFFLE MOVEMENT - Pressing the up or down key during the idle mode will move the muffle
in the indicated direction until it reaches its full travel. Pressing the key while the muffle is moving will stop
the muffle at its current position. See “MUFFLE POSITION” below for muffle movement during the DRY
and COOL portions of the firing cycle.
Key changes the display from Celsius to Fahrenheit and back. The conversion cannot be done during
parameter programming. The units for vacuum also changes from "mm Hg" to "in Hg" when the tempera-
ture units are changed.
PURGE CYCLE: Program "0" is the automatic purge cycle. Load the carbon rod into the muffle in the horizon-
tal position. Change the program number to 0 and then press the key. The Purge Cycle starts
automatically when the key is pressed.
Pressing the (red) key stops the cycle. A complete purge cycle lasts approximately 2 hours.
CAUTION: Do not stop this cycle at elevated temperatures, the release of vacuum can damage the
muffle and cause an unsafe condition.
MUFFLE POSITION:
The "DRY" and "COOL" positions can be adjusted for each furnace. To change the factory preset "DRY" or
"COOL" positions, use the following procedure:

B. PROGRAMMABLE HIGH LIMIT TEMPERATURE:
The user can program a high limit temperature that is lower than the fixed limit of 1204°C built into the control.
This limit will cause the furnace to go into Err3 if the muffle temperature exceeds this value.
1. Press the (ENTER) key twice after turning on the power switch to the furnace when the display
initially shows "Setup?".
2. Enter the digit keys of desired temperature followed by the key and the ESCkey.
C. VACUUM ADJUSTMENT:
The 100% vacuum level can be adjusted if the furnace is being operated at a high elevation or with a weak
vacuum pump. The Vcal should be reduced for higher elevations by subtracting 80mm per 1Km of altitude
from 740mm. (1" for every 1000' from 29")
NOTES: The maximum vacuum possible can be done automatically running program 88. At the end of this
cycle the maximum vacuum pulled will be stored in the setup routine.
1. Press the (ENTER) key three times after turning on the power switch to the furnace when the
display initially shows "Setup?".
2. The display will show the current vacuum setting "Vac Cal" "100%=710mm".
3. Enter the new Vcal value followed by the key. The furnace is now recalibrated to the new value.
Press the key to leave the Setup routine.
4. The maximum vacuum possible for a particular furnace/pump combination can be checked by program-
ming a long hold time with the VAC set to 101%. This will cause the vacuum pump to run continuously.
The maximum vacuum appears on the LCD display. Enter this new value for 100% vacuum in step 3
above. This test should be done after running or firing cycle to assure all moisture is removed from
muffle.
ESC
Silver calibration is not recommend due to its poor accuracy. Silver calibration under ideal conditions is only
accurate to +/- 10°C. If not done correctly, a +/- 25°C error is possible.
The Tcal setup feature allows the operator to adjust for temperature differences between materials and
techniques. If consistent overfiring is occurring, the Tcal value should be reduced by the estimated number of
degrees that it is overfiring. The estimated number of degrees that the furnace is underfiring should be added
to the Tcal value. If the furnace is estimated to be over firing by 15°C then subtract 15 from 960 which results
in 945. 945 is entered into the Tcal value replacing the 960. Procedure:
1. Press the (ENTER) key when the display shows "Setup?" after power is turned on.
2. Enter the desired Tcal value followed by the key.
3. Press the ESC key to exit Setup.
The furnace can be reset to the factory calibration by setting the Tcal value to 960°C. Changes in the Tcal
value affects all temperature and programs.
The CENTURION has a software adjustment program for changes in operation. It is called "Setup". The
following procedure identifies how to use the "Setup" routine to make these types of changes.
The furnace displays "Setup? " after it's internal testing when power is turned on. If the (ENTER) key
is pressed when the word "Setup?" is displayed the furnace will go into an operator "Setup" routine. In this
routine various control characteristics can be reviewed and changed. These include: Temperature Adjust-
ment, Programmable High Limit Temperature, Vacuum Adjustment and Idle Down Time.
Initial Conditions: Furnace is not running a firing cycle and the temperature has been changed to °C readout.
A. TEMPERATURE ADJUSTMENT:
Every CENTURION is calibrated at the factory to 960°C +/- 3°C. This accuracy applies to furnaces that are
temperature stabilized (i.e., furnace has operated at the Lo T for a minimum of 20 minutes).
SETUP & MAINTENANCE:

11
D.IDLEDOWNTIME:
The length of time the furnace waits before closing the muffle when not used can be programmed from 1 to 99
minutes. The time is set to 15 minutes when shipped from the factory. Programming the time to 0 turns off
this feature.
1. Press the (ENTER) key four times after turning on the power switch to the furnace when the
display initially shows "Setup?".
2. The display will show the current programmed time. Use the digit keys to enter a new time in minutes
followed by the key.
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.
User has the responsibility for carrying out appropriate documentation if a hazardous material is spilled on
or inside the equipment.
Before using any cleaning or decontamination method except those recommended by the DENTSPLY
NeyTech, user should check with DENTSPLY NeyTech, that the proposed method will not damage the
equipment.
