The ThermaPrep® Plus Obturator Oven has been specially devel-
oped for heating ThermaPrep® Plus endodontic obturators for use in
root canal therapy. Do not use this oven for any other purpose.
There are none known.
1. Turn the power on by plugging the oven into a 115 VAC
outlet. Both indicator lights around the buttons will light up. To
wake-up the oven from stand-by mode, push and hold either
one of the buttons until the indicator light around the button
is illuminated and two signal “beeps” are heard, and release
the button. A second, lower signal “beep” will sound. On
both sides the smallest obturator size is selected as shown by
indicator lights. The oven is now ready for use. At any time the
oven can be turned off. Push and hold either one of the bottom
buttons until the indicator light around the button turns off.
2. Put both obturator holders in the upper position by pressing the
back of the holder (marked area).
3. DISINFECT the obturator in a 5.25% sodium hypochloride
solution (bleach) for one minute. RINSE the obturator in 70%
alcohol. DRY the obturator for several seconds on a clean work
surface to allow evaporation of excess alcohol.
4. After disinfecting the obturator and setting the rubber stop,
place the ThermaPrep® Plus Obturator in one of the obturator
holders, lightly press on top to have it firmly seated. Regardless
of what working length you have determined, the rubber stop
must be under the holder. Make sure the obturator is hanging
straight, not at an angle. The obturator must clear all sides of
the heating chamber.
5. Push the button which corresponds to the selected obturator
holder, to select the size of the ThermaPrep® Plus Obturator you
wish to heat. Repeatedly push this button to select the correct size.
6. To start the heating process push the obturator holder down
until you hear it click. It will raise a little but keep in a steady
down position. The indicator light around the button will show
that the heater is on (constantly on). The obturator is now being
heated. Heating time varies – depending on obturator size –
from 20 to 49 seconds, and is regulated automatically.
The heating times for the selected obturator sizes are as follows:
Size Signal Time Tolerance
20 — 25 20 seconds ± 5 seconds
30 — 60 44 seconds ± 7 seconds
70 — 140 49 seconds ± 8 seconds
7. After the first signal “beep,” the obturator is ready for use. Push
the back of the obturator holder (marked area) to let it raise
slowly. The indicator light around the button will go off. Take the
obturator carefully out of the holder by pulling it towards you,
making sure not to scrape the obturator on any part of the holder.
8. You may leave the obturator in the ThermaPrep® Plus Obturator
Oven for up to 90 seconds after the first signal “beep.” It will
keep the obturator at the appropriate temperature and ready
for use. The oven will “beep” every 15 seconds to remind you
that the obturator is still in the oven. After 90 seconds, the heat-
ing element will switch off automatically.
9. If you want to heat more obturators, you may use one holder or
both to continue your work efficiently. Each holder is operated
by its own button and indicators. If you hear a signal “beep”
then look at indicator lights around the buttons which indicate
obturator heater is ready (flashing). When both heaters have
finished their cycle and no buttons are pushed, the oven will go
into a power-saving, stand-by mode after 5 minutes.

for Use
The equipment is designed to be safe for indoor use under the following
environmental conditions:
Maximum Altitude 2000 m / 6562 ft
Storage temperature -20 to +65º C
-4 to +149º F
Storage humidity 20 to 80%,
no condensation
Operating temperature +5 to +40º C
+41 to +104º F
Max. operating humidity 80% at +31° C to 50% at 40° C (lin.)
80% at +87° F to 50% at 122° F (lin.)
Mains voltage uctuations Up to ±10% of the nominal voltage

Mass of the equipment .56 kg / 1.23 lbs
Overall size of the equipment (W x D x H) 155 x 178 x 81 mm / 6.1” x 7” x 3.2”
If there is any doubt about the compatibility of decontamination or
cleaning agents please contact the manufacturer or DENTSPLY.

The oven is designed with two precision heating alerts:
1. First size LED button blinks: The targeted temperature of the heat-
ing element was not reached within specified time (time-out). Use
the other heating element to warm the obturator.
This may be re-set by turning the power off and turning the
power on. If the error occurs again the oven should no longer be
used and sent for repair.
2. Second size LED button blinks: The hardware safety circuit has
been activated due to a failure in the heating element, causing
overheating. This may be re-set by turning power off, discon-
nect the power cord, reconnect the power cord, and turn the
power on. If the error occurs again the oven should no longer
be used and sent for repair.
Clean oven after each use. Any gutta-percha remaining on the
holder or in the heating chamber may be effectively removed with
Orange Solvent (generic dental solvent) on a cotton pledget. Press
and hold both buttons at once for 2 seconds to put the oven into
the cleaning mode. This will cause both heaters to heat up to a
medium temperature of 140°F/60°C. The indicator lights around
the buttons will show that the heaters are on (constantly on). A
signal “beep” and flashing indicator lights around the buttons will
warn that the desired temperature has been reached. Disconnect
the main plug and clean the heater chambers with a wire brush, as
directed on the last page of the oven illustration.
To abort the cleaning mode without disconnecting the main plug and
to enter the normal mode again press either button for 2 seconds.
1. To prevent fire or electric shock, do not expose this product to
moisture.
2. Unplug the oven when not in use.
3. Do not remove the cover of the oven.
4. This oven is designed for use in the dental office. Do not use in
any other environment.
5. To reduce the risk of electric shock, do not remove cover; there
are no user-serviceable parts inside.
6. This oven is intended for use in heating gutta-percha coated
obturators only. Do not insert anything other than an obturator
into the oven.
