4 inFire HTC speed Furnace Features and Differences
5 From “inFire HTC” to “inFire HTC speed” HTC speed = 90 minutes vs. 5-7 hrs.Only 90 minutes neededto sinter a zirconium oxide substructureto sinter a 5 unit bridge substructureOnly 90 minutes to sinterFull contour single unit/bridge
6 inFire HTC speed Furnace What remains the same?External design – only the name has been changedPrevious sintering programs still availableAbility to freely set sintering programs if desiredREF# 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 minutesVITA In-Ceram YZ speed in 90 minutesImproved internal insulationHigh performance heating elementsEight additional drying and ventilation programsFor restorations which have been treated with staining liquids
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
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 theygo in flush. Note that there are also 3 holes in the block that will fit onto the 3tubes 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.
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.
38 inFire HTC speed Operation Programming StepsS1-S4 buttons relate toStep 1 – Step 4Step 3 and Step 4 arealways usedFor 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 emptyprogramEnter values fromchart, top to bottomUse S4 key to stepthrough the fieldsfor Stage 4
41 inFire HTC speed Operation Use S3 key to step through Stage 3 entriesPress S3 again toclose the stageData entry iscomplete
43 inFire HTC speed Operation Press the Memory (Store)Button to save the programEnter a name for theprogram if desiredPress the “F” button toselect a letter, then “S4”to move to the next letter
44 inFire HTC speed Operation When finished, pressS2 to confirm.This is how the programwill display when it isloaded. The name willdisplay while you areentering the number, butwill go away when youpress S2 for YES.
45 inFire HTC speed Operation Example of entering a “speed” programIn a speed cycle, the heating velocity must be 30 C/min or greater.
46 inFire HTC speed Operation Using S4 to enter theStage 4 dataContinuing data entrythrough Stage 2. Stage 1 can be left alone sincethe 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 FUNCTIONTo 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.
50 inFire HTC speed Operation Default SettingsBy 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.
52 inFire HTC speed Support Installation problemsIf the thermocouplewires are reversed, there will be an error regarding polarity.The orange wire must be connected to the “+” terminal.
53 inFire HTC speed Support Installation problemsIf 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 problemsIf the door switch is adjusted, you must verify that the door still fully closes.
55 inFire HTC speed Support User ErrorsCOMPLAINT- “When I startthe oven, the door closesbut 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
