inFire HTC speed Furnace Features and Differences Slide 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 Slide 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 Slide 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 Slide 7 inFire HTC speed

Installation Requirements Slide 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 Slide 12 inFire HTC speed Basic Installation Slide 13 -
Shown here on unit, do assembly on table first - Insert ceramic
tubes into holes in lower door insulation block Slide 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. Slide 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. Slide 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 Slide 17
inFire HTC speed Furnace Operation Slide 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 Slide 19
inFire HTC speed Operation Sintering Balls DO NOT pour entire
contents into tray. Use about 2 layers of balls in the tray. Slide
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. Slide 21 inFire
HTC speed Operation Slide 22 Slide 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.

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) Slide 28

Slide 33 Slide 34 Slide 35 Slide 36 Slide 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 Slide 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 Slide 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 Slide 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 Slide 41 inFire HTC speed
Operation Slide 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 Slide 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. Slide 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. Slide 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.
Slide 46 inFire HTC speed Operation Save and name the program as
before. Display showing our new program 12 speed cycle. Slide 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. Slide 48 inFire HTC
speed Operation Additional Functions Slide 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. Slide 50 inFire HTC speed Furnace Support
Installation problems User errors Voltage calibration Performance
Slide 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
Slide 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 Slide 53 inFire HTC speed Support If the door switch is
adjusted, you must verify that the door still fully closes.
Installation problems Slide 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 Slide 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. Slide 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 Slide 57 inFire Q & A CAD/CAM Webinar
