3 inFire HTC speed Furnace Features and Differences

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

5 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 inFire HTC speed Furnace

6 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

7 inFire HTC speed Support “speed “ parts Front Panel Controller Board Heater Elements Sintering Cup Insulation

10 inFire HTC speed- Installation Requirements

11 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 - Install door insulation - Remove packing material from inside the furnace

12 inFire HTC speed Basic Installation

13 - Shown here on unit, do assembly on table first - Insert ceramic tubes into holes in lower door insulation block

14 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.

15 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.

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

18 inFire HTC speed Operation Sintering Trays Original Infire trays- CANNOT be used on speed cycles Infire speed trays- can be used on ALL cycles

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

20 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.

23 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.

25 Power-On Display (about 3-4 seconds)

26 inFire HTC speed Operation Standby Display - Current Status - Current Program - Temperature - Current Day and Time - Estimated Completion Time

27 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)

37 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

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

39 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

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

41 inFire HTC speed Operation

42 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

43 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.

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

45 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.

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

47 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.

48 inFire HTC speed Operation Additional Functions

49 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. 300 C is the maximum setting.

50 inFire HTC speed Furnace Support Installation problems User errors Voltage calibration Performance

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

52 inFire HTC speed Support 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. Installation problems

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

54 inFire HTC speed Support 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. User Errors

55 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.

56 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
