1 Warning and safety information
Intended use Even when it is not strictly necessary, the instrument
wrapping indicates a special care paid to the hygiene
and sterilisation and it is especially effective for a proper
infection safety.
Wrapping the instruments means to preserve their ste-
rile condition also during the period following the sterili-
sation and until their use on the patient.
A properly sealed envelope makes up a protection bar-
rier that prevents contamination from the external envi-
ronment.
For this to be true, it is necessary to use envelopes that
have been properly sealed.
The NITRASEAL Thermal Sealer guarantees the best
efficiency and reliability for the sealing system, avoiding
the risk of overheating and burning.
Inexperienced staff can easily use this equipment with a
quick training.
General recommendations In order to maintain the instruments for a long time and
avoid problems it is recommended to read the following
instruction carefully.
1. Wrap the instruments one by one.
2. If more instruments must be wrapped together make
sure to place instruments of same material (on the
contrary, dark spots could appear at the contact
point due to electrolysis).
3. It is recommended to use good quality paper and
propylene material. The paper surface (more po-
rous) must allow the vapour exit. The NITRASEAL
envelopes has been widely tested in order to give
the best results both for quality and durability.
4. For the sterilisation of wrapped instruments, it is ne-
cessary to use longer sterilisation times. The vapour
must actually filter within the envelopes and this re-
quires longer times.
5. Most autoclaves normally require a time of 12 minu-
tes at a temperature of 134 °C and 30 minutes at
121 °C.
6. The envelopes should be placed inside the autocla-
ve with the paper surface up. This allows the vapour
exit easier during the drying phase.
7. Do not overload the sterilisation chamber! Leave a
space for steam circulation.
8. In case of sterilisation of wrapped hand pieces and
turbines, try to arrange the envelopes so that the
head of the hand piece is turned towards the upper

surface of the chamber. This will allow the lubricant
in excess to filter out protecting the life of the instru-
ments.
9. If the autoclave does not have an efficient drying
system, the envelopes could remain damp. In this
case, it is recommended not to use the wrapping
technique, since there is a risk of damaging the ins-
truments. Consult your supplier to work out this pro-
blem.
Safety information Before using Your NITRASEAL Thermal Sealer, read
these safety instructions carefully. Non-compliance with
these standards could cause incidents or damage to the
appliance.
• Do not introduce fingers in the sealing area when the
machine is on.
• Do not introduce fingers under the protection cover
of the sealing area when the pressure lever is
lowered.
• Do not insert your fingers in the sliding surface of the
cutter.
• Keep the area around the sealer clean and dry.
• Never disassemble the NITRASEAL thermal sealer
when it is powered, since the high internal voltage
could be dangerous.
• In case of impossibility for disconnecting the power,
turn to OFF the breaker of the electrical switchboard
and place a sign Work in Progress on the breaker if
this is far and not visible by the person that is carry-
ing out the maintenance.
• Clean the appliance with a soft damp cloth after un-
plugging the power supply cable. Do not use sol-
vents on the product label.
• Check that the machine is electrically grounded in
compliance with the standard of the country of instal-
lation.
• Do not remove the back label and check that the
sealer is supplied with proper voltage value.
Electrical connection
Check that the power data indicated on the label on the
rear side of the sealer corresponds to the values availa-
ble in the place of installation.
The equipment must be connected through the mains
cable to a socket provided with a ground connection in
compliance with the standard of the country of installa-
tion.
CAUTION
Do not bend the cable and do not place any object on it.

5 Operation
1. Connect the power supply cable of the NITRASEAL
Thermal Sealer to a mains socket after having che-
cked the electrical requirements reported on the la-
bel.
2. Turn on the equipment by the power switch placed
on the back side; the green and the yellow light indi-
cators will turn on; after a few seconds the yellow in-
dicator will switch off and only the green one will stay
on to signal that the appliance is ready.
3. Place a sterilisation roll on the special stand. In case
of model with a roll-holder, place the rolls in the rod
and put it on the supports.
4. Set the potentiometer to a middle position. For the
adjustment see the paragraph ADJUSTMENTS.
5. Insert the envelope under the roll behind the heating
element and push it until it goes beyond the heating
element and appears on the front side.
CAUTION
The envelope must have the transparent (polypropylene)
side up.
6. Advance the envelope for all the length of the instru-
ment to be enveloped.
7. To seal the envelope grasp the lever and pull it for-
wards and down. In this way the sealing element is
lowered and presses the envelope against the hea-
ting element.
8. On complete run of the lever the green indication will
start to flash to signal that the sealing is in progress
(this phase lasts 9 and 4 seconds depending on the
machine is cold and hot respectively).
9. When sealing is over the yellow light switches on
and an acoustic message is played.
10. Cut the envelope before releasing the lever. To do
this push the knob placed over the sealing element
and move it firmly along the sliding track of the cutter
both rightwards and leftwards.
11. Return the lever to rest position to lift the sealing ele-
ment and free the envelope just cut.
5 Operation Sirona Dental Systems GmbH
Operating Instructions NITRASEAL
61 79 761 D 3367
12 D 3367.201.02.01.02
CAUTION
the yellow indication will stay on for about 3 or 4 seconds
at the end of the sealing. This pause is necessary to avo-
id overheating: during this time it is not possible to carry
out another sealing.
12. In order to seal the opposite side of the envelope
and so block the instrument within its protective co-
ver, the envelope must now be turned and inserted
under the sealing element from the front; then carry
out a new sealing.
CAUTION
In order to avoid the sealing operations along the outer
margins of the heating element, place the sterilisation roll
on its special stand, so that the envelope may slide along
the middle part of the heating element.
