Features and Differences

5. From “inFire HTC” to “inFire HTC speed”
HTC speed = 90 minutes vs. 5-7 hrs.
Only 90 minutes needed
to sinter a zirconium oxide substructure
to sinter a 5 unit bridge substructure
Only 90 minutes to sinter
Full contour single unit/bridge

6. inFire HTC speed Furnace
What remains the same?
External design – only the name has been changed
Previous sintering programs still available
Ability to freely set sintering programs if desired
REF# is the same

7. inFire HTC speed Furnace
What kind of changes are there in the new inFire HTC speed?
Two additional fast sintering programs:
inCoris ZI speed in 90 minutes
VITA In-Ceram YZ speed in 90 minutes
Improved internal insulation
High performance heating elements
Eight additional drying and ventilation programs
For restorations which have been treated with staining liquids

Installation

11. inFire HTC speed- Installation Requirements

12. inFire HTC speed Basic Installation
- Connect Power Cord to NEMA 6-20 Outlet
- Turn on power switch
- Door will open
- SENSOR BROKEN error and loud beep due to thermocouple not connected yet
- Turn power switch OFF
- Remove packing material from inside the furnace
- Install door insulation

13. inFire HTC speed Basic Installation

14. inFire HTC speed Basic Installation
- Shown here on unit, do assembly on table first
- Insert ceramic tubes into holes in lower door insulation block

15. inFire HTC speed Basic Installation
Insert the guide tubes into the upper door insulation block such that they
go in flush. Note that there are also 3 holes in the block that will fit onto the 3
tubes on the lower insulation.

16. inFire HTC speed Basic Installation
- Now attach the lower and upper blocks together by fitting the upper block over the ceramic tubes. It may be easiest to do this by holding the blocks on edge to keep the guide tubes from falling out.
- Place the completed insulation into the door such that the open area between the pins faces forward.

17. inFire HTC speed Extended Installation
- To be performed by Patterson Technician ONLY
- Heating elements and wiring braids must be installed.
- Make sure the bolts that secure the power cables to the heater element braided cable are tight
- Thermocouple must be installed.
- Run Program 00 to test and calibrate the voltage.

Sintering Trays
Original Infire trays-
CANNOT be used on speed cycles
Infire speed trays- can be used on ALL cycles

20. inFire HTC speed Operation
Sintering Balls
DO NOT pour entire contents into tray.
Use about 2 layers of balls in the tray.

21. inFire HTC speed Operation
A tray can be loaded with up to about 25 units, depending on type.
Restorations must have room to move and not contact each other or the side of the tray.

22. inFire HTC speed Operation

23. inFire HTC speed Operation

24. inFire HTC speed Operation
When using color or staining liquids, the sintering balls will become stained. This can discolor any non-stained restorations that are sintered in this tray.
A separate sintering tray should be used for stained restorations.

28. inFire HTC speed Operation
Overview of Programs
- 7 fixed programs (01-07) for inLab approved materials
- 3 reserved programs (08-10)
- 12 freely programmable programs (11-22)
- 2 further programs with ventilation (23 and 24)
- 6 further programs with predrying (25-30)

Programming Steps
S1-S4 buttons relate to
Step 1 – Step 4
Step 3 and Step 4 are
always used
For an unused stage,
enter 0 for Temperature

39. inFire HTC speed Operation
Programming Steps -
Create a new program cycle
- Contact the material manufacturer for specifications and recommended heating and duration values
- Make a programming chart with the desired values, going in reverse order from top to bottom

40. inFire HTC speed Operation
Load an empty
program
Enter values from
chart, top to bottom
Use S4 key to step
through the fields
for Stage 4

41. inFire HTC speed Operation
Use S3 key to step through Stage 3 entries
Press S3 again to
close the stage
Data entry is
complete

42. inFire HTC speed Operation

43. inFire HTC speed Operation
Press the Memory (Store)
Button to save the program
Enter a name for the
program if desired
Press the “F” button to
select a letter, then “S4”
to move to the next letter

44. inFire HTC speed Operation
When finished, press
S2 to confirm.
This is how the program
will display when it is
loaded. The name will
display while you are
entering the number, but
will go away when you
press S2 for YES.

45. inFire HTC speed Operation
Example of entering a “speed” program
In a speed cycle, the heating velocity must be 30 C/min or greater.

46. inFire HTC speed Operation
Using S4 to enter the
Stage 4 data
Continuing data entry
through Stage 2. Stage 1 can be left alone since
the temp is set at 0.

47. inFire HTC speed Operation
Save and name the program as before.
Display showing our new program 12 “speed” cycle.

48. inFire HTC speed Operation
CASTING TIME FUNCTION
To start a program with the casting time function, press the “Casting Time” button. Note that the status changes to “AUTOST”
Use the S1 key to position the cursor, and the numeric keys to enter the day and desired completion time. The start time shown to the left will update.
Press START/STOP, the function is now activated. To quit the program, press the “Casting Time” button again.

49. inFire HTC speed Operation
Additional Functions

50. inFire HTC speed Operation
Default Settings
By pressing the “F” button, the following settings may be changed. S2 sets the current day and time.
“Lift temp” is the temperature at which the door will open C is the maximum setting.

Installation problems
If the thermocouple
wires are reversed, there will be an error regarding polarity.
The orange wire must be connected to the “+” terminal.

53. inFire HTC speed Support
Installation problems
If the door closes and then opens again, the upper door switch is probably not being actuated. This switch may need to be adjusted downward slightly.

54. inFire HTC speed Support
Installation problems
If the door switch is adjusted, you must verify that the door still fully closes.

55. inFire HTC speed Support
User Errors
COMPLAINT- “When I start
the oven, the door closes
but it never heats up.”
PROBLEM- The user thinks that “START/STOP” is just a label for the UP/DOWN button and presses the UP/DOWN by mistake. The door closes but the status never changes to RUN.

56. inFire HTC speed Support
Voltage Calibration
- The furnace controller assumes an average voltage of 230V
- When calculating the start time, the time may not be accurate if the site voltage varies from 230V
- Load program 00 to run the correction program to correct the values on the controller board for accurate calculations.
- The program takes 3-4 hours to run. If necessary, you can stop it by pressing the Start/Stop key.

57. inFire HTC speed Support
Performance
- The restorations come out discolored
- This is NOT due to using a tray that is used for coloring
- Run program 00 with empty chamber
