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.

and wipe the chamber with a clean cloth. 


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

in the chamber and select the first sterilization cycle. 

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.

• “PRESS.” display shows day and month 

• “TEMP” display shows OFF 

2. Press key POWER on the front control panel and wait a few seconds for the 
automatic autotest completion; during this period the set-points of the 
parameters and the check-up of the main assemblies will appear in 
sequence on the display. Ended the autotest, the upper display “TIME” will 
show again the current time, the display “PRESS” the pressure into the 
chamber, the display ‘TEMP” the chamber temperature (or the message 
“Low” if lower than 35°C). The pre-heating process starts and the 
microprocessor drives the heaters at reduced power in order to set the 
chamber surface temperature up to about 100°C.

During this phase the temperature reading on the display is inaccurate, 
because no steam being there. 

3. Arrange the material to be sterilized on the trays, load the tray into the 
chamber and close the door. 

4. Verify that the red Led MIN of the main tank is off. If not fill up the main tank 
with demineralized water up to the lighting of Led MAX.

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 


14 


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).

4.3 STOPPING THE CYCLE 

To stop the sterilization cycle, press the key START/STOP. 

The upper display will show MANU STOP. 

Before opening the door, make sure that the pressure value 
PRESS is equal to zero. A safety device will anyway prevent 
door if the chamber is over-pressurized. 

Remove the instruments and check for the presence of water 
In case of wrapped instruments, we suggest to replace with new.bags. 

In case of residual water in the chamber, wait 10 minutes before loading again 
the chamber so as to allow the water to evaporate and be drained. Wipe the 
chamber with a clean cloth.

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.

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.
