speed- Installation RequirementsSlide11
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
Slide12
inFire HTC speed Basic InstallationSlide13
inFire HTC speed Basic Installation
- Shown here on unit, do assembly on table first
- Insert ceramic tubes into holes in lower door insulation blockSlide14
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.Slide15
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.
Slide16
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

Sintering Balls
DO NOT pour entire contents into tray.
Use about 2 layers of balls in the tray.
Slide20
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.Slide21

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.

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 Slide39
inFire HTC

Load an empty
program
Enter values from
chart, top to bottom
Use S4 key to step
through the fields
for Stage 4Slide40

Use S3 key to step through Stage 3 entries
Press S3 again to
close the stage
Data entry is
completeSlide41

Press the Memory (Store)
Button to save the program
Enter a name for the
program if desired
Press the “F” button to
s
elect a letter, then “S4”
t
o move to the next letterSlide43

When finished, press
S2 to confirm.
This is how the program
will display when it is
loaded. The name will
display while you are
e
ntering the number, but
will go away when you
press S2 for YES.Slide44

Example of entering a “speed” program
In a speed cycle, the heating velocity must be 30 C/min or greater.Slide45

Using S4 to enter the
Stage 4 data
Continuing data entry
through Stage 2. Stage 1 can be
l
eft alone since
the temp is set at 0.Slide46

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.Slide48

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.

PerformanceSlide51
inFire HTC speed Support
If the thermocouple
w
ires are reversed, there will be an error regarding polarity.
The orange wire must be connected to the “+” terminal.
Installation problemsSlide52
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 problemsSlide53
inFire HTC speed Support
If the door switch is adjusted, you must verify that the door still fully closes.

COMPLAINT- “When I start
t
he 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
Slide55
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.
Slide56

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
