3. INSTALLATION

3.1 BASIC REQUIREMENTS

1. Make sure that the features of the electric plant is according
with the requirements indicated on the rear plate, the power
supply socket should provide at least 10 A and adequate
earth connection.

The manufacturer disclaims any responsibility for
damage caused by inadequate or not earth-
connected electrical plant.

2. The sterilizer should be slightly tilted to facilitate water outflow
during the steam draining phase. For this reason the
equipment is delivered with feet already set; if necessary
adjust the front feet.

3. To warrant the correct working of the sterilizer it is imperative
that the rear and lower panels are not clogged and that the
unit is not installed in extremely moist environments or
arranged close to inflammable gas sources.

4. The distance from the rear wall should be at least 4 cm.

The sterilizer may be installed recessed, as long as adequate free
space around the unit (> 10cm) is guaranteed.

SIROCLAVE B

Sirona Dental Systems GmbH

3.2 PRELIMINARY STEPS

These adjustments should be carried out only by
qualified service technicians. Incorrect settings might
effect the quality of sterilization.

1. Verify that the electric plant meets the equipment
requirements; plug the power supply cable into an AC socket.

2. The sterilizer is delivered without water into the tank; before
proceeding it is necessary to fill the tank with demineralized
water.

Poor-quality water might lead to calcareous deposits on
the instruments, chamber walls and trays. Read the label
carefully before using the water. Tap water must never
be used , even if conditioned through filters or softeners.

A Never use battery distilled water bottles as the sulfuric

/1 \ acid additioned will cause irreversible sterilizer’s

/ l \ damage.

Fill completely the distilled water tank.

3. Turn-on the sterilizer by the rear power supply switch. This
should preferably be kept in “on” position, as in stand-by
status the power consumption is very negligible.

4. Take basket and trays out of the chamber and close the door.

5. Hold pressed the key o and select the key POWER; the

display will show <SET ALT 100 MT> (100 is the factory-set
standard altitude value).

Modify the value according to the current installation altitude
(see next page) by operating on the keys Q or 0

Then press the key SET to store the set value and to start
the automatic procedure for the first water filling of the
hydraulic circuit and the chamber itself.

SIROCLAVE B

Sirona Dental Systems GmbH

6. At the turning on of the signaling READY, open the door and
and wipe the chamber with a clean cloth.

In case of wrong procedure or incorrect condition, the display
show one of the following warnings:

instructions are detailed on chapter 4

3.3 NOTES ABOUT THE ALTITUDE
COMPENSATION

To ensure the correct operation of the sterilizer’s pressure
transducer the equipment must know the environment data in
order to allow the necessary pressure compensation.

The correct altitude value (above sea level) must be set at the first
installation and in case the sterilizer is moved at altitude differing
from the set value. a

The factory-set value is 100 meters. If the actual altitude is
between 0 and 200 meters no adjustment is needed. Differences
of ±100 meters do not affect the correct sterilizer operation.

To ensure the right sterilization verify that the altitude value set
during the installation does not differ from over 200 meters from
the current one. An incorrect altitude setting may result in a
prolonged vacuum cycle and/or false or premature AL8 and AL5
error messages.

To select the program 1 , 2 or 3 press on the relating key.

To select one of the programs of the option 4, hold pressed the key 4 and select
the key 1 or 2 to display the choice (SI ,S2, S3, S4 or S5) on the middle display.

The displays will show for 5 seconds the preset parameters of the selected cycle.

4.2.2 Running the cycle

Press the key START/STOP to start the selected program.

Programs 3, SI and S5 do not grant a class B sterilization; to start these
type of programs previously selected, hold pressed the key 3 (or 4) and
select the key START/STOP.

Once again the preset parameter values of the selected program are displayed
for 10 seconds, then the sterilizer starts to run automatically in sequence the
phases of the cycle. The various steps of the cycle are microprocessor controlled
and sequentially shown on the display; in this way the operator can monitor the
cycle phases and times.

• Led VACUUM turns ON

• Upper display TIME starts recording the cycle duration

• Display PRESS shows the pressure

• Display TEMP shows the temperature

• The Led on the program key selected starts to blink

In this first phase the microprocessor enables the vacuum pump and supplies a VACUUM phase (chamber
water dose into the chamber. The Led VACUUM flashes. This phase will be water filling and pre-vacuum

repeated more times and should require 10 to 20 minutes depending on the phases)

chamber conditions and the type of material to be processed. Pump operation
may be slightly noisy.

C ® B * For unwrapped solid instruments we recommend to use the cycle 3. In
this way the sterilization time will be faster, and power consumption
reduced.

Reached the pre-set parameter values, Led VACUUM turns OFF, and Led
STERILIZE turns ON. The upper display starts the countdown marking the
remaining time for the sterilization process; the other displays are showing the
steam temperature and pressure values.

STERILIZATION phase

SIROCLAVE B

Sirona Dental Systems GmbH

Ended the sterilization phase, starts the decompression phase, with the PRESS
display showing the decreasing pressure values down to 0. Again, the display
TIME will start the countdown of the decompression phase. Based on previous
experiences, the decompression time has been slightly extended in order to
minimize the thermal shock consequent to the steam changing its state.

When decompression is through, Led STERILIZE starts to flash to signal the
process has been completed. At the same time Led DRYING turns ON, signaling
the start of the drying cycle. Throughout this phase, the heaters hold the
chamber warm according to a microprocessor-controlled differentiated logic, the
vacuum pump comes into operation again to suck in all residual steam. Display
TIME shows the countdown of this phase.

Follows the forced ventilation through the bacterial filter; the countdown of this
phase is signaled on the display TIME.

Ended the drying phase, Led DRYING turns OFF and Led READY and
STERILIZE turn ON. A 10-second alert signal is generated to draw the attention
by the operator. The heaters are swilched to a reduced power until the door Is
open. Display TIME will show the total time of the cycle, and the displays TEMP,
and PRESS the chamber current temperature and pressure.

At the end of the cycle 3, SI or S5, only Led READY will light (not the
Led STERILIZE) to signal that the cycle selected by the operator does
not grant a class B sterilization.

The process is over and the instruments can be downloaded.

Be careful!,

both instruments and chamber are hot!

Opening the door, the displays will show again the current time, chamber
temperature and pressure, and the sterilizer is ready for a new cycle.

If a printer is connected and ready, a report will be issued during the cycle
phases with significant information, allowing a proof of the sterilization process.

The operator can arrange a new load and start a next sterilization cycle, taking
the advantage of shorter warming-up time as the chamber is already warm, or
press the key POWER to switch in stand-by status the unit (OFF status).

If the door is not opened or no key is pressed within 30 minutes from the end of
the cycle, the sterilizer will switch automatically in stand-by (OFF status).

Should any failure or error occur during the cycle, Led ALARM turns ON and the
upper display will show the alarm type and code (see chapter ALARM).

4.4 TOPPING UP THE MAIN TANK - DRAINING THE
USED WATER TANK

The sterilizer is fitted with two 4-liters tanks: main tank for the demineralized
water and recovery tank for the used water.

The hydraulic system does not reuse the steam generated during the sterilization
process; this steam is collected in a recovery tank that must be periodically
drained. This mode of operation involves the progressive emptying of the main
tank and the filling of the recovery tank.

Main tank Recovery tank

4.4.1 Topping up the main tank

The average water consumption for any sterilization cycle is 520 cc, so 7 cycles
can be performed by the tank fully loaded.

The lighting of Led MIN signals the operator that the water level in the main tank
is insufficient to perform a new process.

Provide for the topping up of the main tank, taking care to not exceed the limit of
the hole’s grid. The lighting of Led MAX and 7-beep signal warns that the tank is
full.

4.4.2 Draining the recovery tank

The lighting of Led MAX relating the recovery tank warns that the overflow limit
has been reached. In this case:

• Get a bucket or a tank with a capacity of at least 4 liters,

• Fit the draining hose into the gray-colored fast fitting (unthreaded side),

• Wait until the water has been completely drained,

• Unfit the hose pushing the ring nut against the machine and drawing the
hose.

4.5 SOUND WARNING SIGNALS

In order to make SIROCLAVE B operation even simpler and more user-friendly, some acoustic signals are generated to
draw the attention of the operator at the main steps of the sterilization cycle or at the occurring of an alarm:

• Whenever a key is pressed, a short beep is generated.

• 3 beeps signal the end of the switching-on autotest.

• 10 beeps signal the end of the sterilization process.

• 1 intermittent beep signals that the door has not been properly closed.

• 30-seconds beep warns the operator in case an alarm occurs during the cycle.

• 7 beeps signal that the main tank is full.

6.2 CLEAN THE INSTRUMENTS BEFORE

In order to extend the sterilizer life, we recommend to carry out an accurate
cleaning of instruments, as one of the main causes of an early wear of the
unit is the settlement and accumulation of debris and fragments for an
inadequate cleaning of the instruments. A consequent stains, fouling and
progressive clogging of filters, electrovalves and hydraulic circuits will occur.

We remind you that the electronic control system tracks and stores the
number of maintenance cycles actually performed.

The lacking of appropriate and regular maintenance according to the above
guidelines may require early service activities and involve the warranty lapse.

REPLACEMENT

The water filter is located at the left side of the stainless steel front panel; to
carry out its cleaning or replacement, proceed as follows:

1. Empty the main tank by plugging the hose (unthreaded end) into the fast
fitting located at the right side of the front panel,

2. Use a coin to unscrew the cap closing the filter seat; pay attention for
possible overflow of the residual water in the tank connecting internal
tube. Unscrew the filter using the supplied spanner,

3. Clean the filter by compressed air (or ultrasonic cleaner) or replace it if
the filter is damaged,

4. Reassemble the filter in its seat and the cap by a coin without tightening
both excessively,

5. Fill the main tank with demineralized water as for the standard operation
of the unit.

6.4 REGULAR STERILITY CHECKS

For a correct use of the sterilizer, it is advisable to carry out sterility tests regularly. In particular, we suggest to carry out
the microbiologic tests, Bowie & Dick and Helix test that may be easily find on the market. For carrying out these tests,
refer to the instructions and indications provided by the suppliers.

For the microbiologic tests, we recommend to place biological indicators at different points of the sterilization chamber in
order to verify the homogeneity of the sterility conditions. For more information, please call your retailer or Sirona Dental
Systems directly.

SIROCLAVE B have been submitted to strict tests of sterility by University of Siena (Institute of Hygiene and Human
Anatomy). According to the international standard, all the sterilizers are moreover tested in factory with the above tests.

6.4.1 Bowie & Dick Test

The test can be performed at any time with sterilizer turned on and operating.

Load the sterilizer with a B&D test (i.e. 3M™ COMPLY™ code 1300)
according to the standards for the test procedure.

With the unit switched-on, hold pressed the key TEST and press on the
key START/STOP.

The test is characterized by the cycle parameters of 3 pre-vacuum phases,
134°C and 3,5 minutes for sterilization temperature and time respectively.

6.4.2 Vacuum Test

Take care to carry out the test at the beginning of the working day in
order to check the leakproof of the chamber and vacuum system.

The test can be enabled on condition that the machine is in stand-by mode
(signaling OFF on the display) and the internal temperature is lower than
35°C (normal conditions at the beginning of the day).

Press the key TEST

The vacuum test starts automatically and takes about 15 minutes.

Ended the test, the sterilizer goes back in stand-by mode; press key
POWER to set for a new cycle.

In case of negative result, alarm display will show the signaling TEST FAIL to
warn for an insufficient vacuum condition in the chamber (see Chapter 8 -
Alarms).

7.2 AUTOMATIC TROUBLESHOOTING

Switching on the unit, an automatic 15-sec. duration troubleshooting cycle is started. 3 beeps are generated at the end
of this autotest. During this test the main components are sequentially controlled.

If the test is positive, message Card Good will be shown. Whatever fault occurs, this is shown on the display and stored
according to the alarm codes listed in table C (see chapter ALARM).

To skip the troubleshooting, press any key as soon as the sterilizer is switched-on.

7.2.1 Water quality check

In order to prevent fail due to poor quality of the demineralized water, the Siroclave B is equipped with a special water
quality check system.

The control, based on water conductivity measurement, is performed at the switching on of the autoclave and on
condition that the machine is cold and the main tank is full.

At the end of the initial autotest the display will show “H20 good” if the conductivity is below 15 pS and “H20 hard” if
above 15 pS.

ATTENTION

The negative result of the water quality check does not jam the operation of the sterilizer, but we strictly
recommend to replace and change the water type.
