DESCRIPTION OF THE INTERNAL WATER TANKS
The sterilizer is equipped with two independent water tanks, one for clean water and one for used water
(capacity of 3.5 liters each).
The tank on the right side is called "clean water tank" and has to be filled with distilled or demineralized
water required for the sterilization process. It is fitted with a minimum (0.6l) and a maximum (3.5l) water
level sensor. The tank can be filled manually through the tank hole on the top of the sterilizer or automatically with an external water supply system (LisaDem 32 or LisaOsmo) connected to point D2 at the back of
the sterilizer (see § 4.5).
Use the quick connector behind the service door (left/blue) to drain the clean water tank for cleaning purposes (see chapter on maintenance).
The tank on the left side is called "used water tank" and contains the used water collected at the end of
each sterilization cycle. It is fitted with a maximum water level sensor (3.5l).
Use the quick connector behind the service door (right/gray) to drain the used water tank (see chapter on
maintenance).
The used water tank can also be drained automatically by connecting a drain tube to the D4 fitting located
at the back of the unit (see § 3.3 and § 4.6).

5.4.2
Automated water supply (optional)
If an automated water supply system is connected to the sterilizer
(see § 4.5), the clean water tank gets automatically filled once the
water level drops below the minimum level.
An internal water conductivity sensor constantly monitors the water
quality. Should the water quality go beyond a maximum threshold
(>15µS/cm conductivity as defined by the European Norm EN
13060), a warning message is displayed on the screen (see screenshot to the right).
Water of low quality can impair the sterilization process and seriously damage the internal components of the sterilizer. Damages caused by poor water quality will not be
covered by the manufacturer’s warranty. Once this message is displayed, check the
water source (refer to the water supply system user manual; replace resin cartridges
etc.). In case distilled or demineralized water is purchased from the market, switch to a
brand of better quality.

5.5
DRAINING OF THE USED WATER TANK
When the waste water in the used water tank reaches the maximum
level, the following message is displayed:
The message will disappear once the used water tank got drained.
Keep draining the tank until it is completely empty.
5.5.1
Manual draining
•
Open the service door at the front of the sterilizer.
•
Insert the drain tube into the quick connector for the
used water (gray connector / right).
•
Let the used water tank drain until it is completely
empty.
•
Press the push-button on top of the quick connector to
dislodge the drain tube.
NEVER RE-USE THE USED WATER!
5.5.2
Continuous draining
If the permanent drain tube for automated draining of the used water is mounted, the used water tank gets
drained automatically. For more information see § 4.6.
If the sterilizer is not used for more than 3 days, both water tanks must be completely drained in order to avoid algae growth or any other deposits.
5.6
MEMORY CARD (optional for 300 Series)
5.6.1
Inserting / removing the memory card
All models of the Lisa 500 Series (optional for 300 Series) are
equipped with a digital cycle data recording system. Cycle data is
written and saved on removable/rewritable memory cards.
-
Insert the memory card into the dedicated slot behind the service
door until it clicks into its final position. Ensure that the flat corner
of the card points to the top/right (see image to the right).
-
Periodically remove the memory card to download cycle data to
a computer.
-
To remove the memory card, slighty push it in and pull it out
gently.

RUNNING A STERILIZATION CYCLE
7.1
THE AVAILABLE STERILIZATION CYCLE PROGRAMS
The following table shows the variety of sterilization cycles available and the different type of loads that can
be processed in the sterilizer. In total there are 3 type B sterilization cycles; 2 cycles offer the ECO-B option (fast type B cycle for a limited load weight; see § 7.1.2).
B-UNIVERSAL 134
This cycle is a type B sterilization cycle (suitable for all types of loads; solid,
porous, hollow A and B; unwrapped, bagged, single or double wrapped)
that features a pre-vacuum phase, a plateau time (sterilization or holding
time) of 4 minutes at a temperature of 135.5°C and a post vacuum drying
phase. See the table on the following page for further details.
B-PRION 134
This cycle is a type B sterilization cycle (suitable for all types of loads; solid,
porous, hollow A and B; unwrapped, bagged, single or double wrapped)
that features a pre-vacuum phase, a plateau time (sterilization or holding
time) of 18 minutes at a temperature of 135.5°C and a post vacuum drying
phase. See the table on the following page for further details.
B-UNIVERSAL 121
This cycle is a type B sterilization cycle (suitable for all types of loads; solid,
porous, hollow A and B; unwrapped, bagged, single or double wrapped)
that features a plateau time (sterilization or holding time) of 15 minutes at a
temperature of 122.5°C and a post vacuum drying phase. The cycle is primarily designed for loads that do not withstand temperature levels of
135.5°C. See the table on the following page for further details.
ECO-B OPTION
When selecting a “B-UNIVERSAL 134” or a “B-PRION 134” cycle, you
have the option to initiate an “ECO-B” cycle instead. The “ECO-B” cycle
features the same sterilization parameters as the “B-UNIVERSAL 134” or
“B-PRION 134” cycles with a shorter drying time. The “ECO-B” cycle is designed for small loads only. See the table on the following page for further
details.
All available sterilization cycles feature the same pressure profile as shown in the graph below. Only the
duration of the plateau time (sterilization or holding time), drying time and the sterilization temperature
vary. The “ECO-B” option shortens the drying time (for small loads only).

ALARMS
Lisa sterilizers constantly monitor a variety of parameters during the sterilization cycle to assure a proper
sterilization of the load. In case any of the parameters is off, potentially affecting the sterilization efficiency,
the cycle is immediately interrupted and an alarm message is displayed.
Once the sterilizer generates an alarm message, a twominute reset phase starts to drain the pneumatic circuits
and to bring the chamber back to atmospheric pressure.
At the end of the reset phase, the door can be unlocked by
pressing the “Unlock door” icon. The screen will display the
type of alarm that was generated and indicate the condition
of the sterilization load. Refer to § 10 for alarm-code troubleshooting.
If an alarm message is generated before the sterilization/plateau phase (PR) of the sterilization cycle is completed, the following message will be displayed:
!! Load not sterile !!
If an alarm message is generated after the completion of the sterilization/plateau phase
of the sterilization cycle (e.g. during the drying phase), the following message will be
displayed:
!! Sterile conditions achieved, drying interrupted !!
Both messages are printed or saved on the memory card (optional for 300 Series).

STERILIZATION LOAD PREPARATION
Cleaning the instruments
The instruments to be sterilized must be clean, dry and free from any residue such as fragments,
dentine, blood, etc. These substances can damage the objects placed in the sterilizer, the sterilizer
itself and may prevent the achievement of sterile conditions of the load.
−
Clean the instruments immediately after use. Follow the manufacturer’s instructions (e.g. when
using an ultrasonic cleaner).
−
Remove all traces of disinfectants from the instruments as this may cause corrosion during the
sterilization process. Rinse and dry instruments thoroughly.
−
2.
Lubricate rotating instruments in accordance with the manufacturer’s instructions.
Preparing the trays
-
For each program, do not exceed the maximum load weight limits that have been set, tested
and validated by the manufacturer (see § 7.1).
−
Always use the chamber rack to allow adequate steam circulation between the trays.
−
Do not overload the trays.
−
Leave a gap/space between sterilization bags to allow steam to circulate properly.
−
Position sterilization bags with the paper side facing up.
−
Empty containers or non-perforated trays must be placed upside down to prevent accumulation
of water.
−
Items made from different materials (stainless steel, carbon steel, aluminum, etc.) must be
bagged or placed on separate trays.
−
Where instruments are manufactured from carbon steel, paper should be placed between them
and the sterilizer tray.
−
Sterilize instruments with joints (e.g. forceps, extraction pliers, etc.) in the open position.

MAINTENANCE OF DENTAL HANDPIECES
External disinfection
This procedure reduces the risk of infection during cleaning and maintenance of the instrument.
−
Wear protective gloves during disinfection.
−
Refer to the instructions of the instrument manufacturer.
−
Avoid using abrasive disinfectants (ph-value 2.5 – 9; no chlorine based disinfectants).
−
We recommend the use of disinfectant wipes rather than spray disinfection.
−
Do not immerse instruments in disinfectants.
Leftover disinfectants can cause extensive damage to your instrumentation during sterilization (oxidation, alteration of technical characteristics of seals, rubbers, fiber optics, etc.)
2.
External cleaning
This procedure involves the removal of residues (blood, dentine, etc.), which adhere to critical areas
such as spray outlets, light ports, knurling etc.
3.
−
Wear protective gloves during cleaning.
−
Refer to the instructions of the instrument manufacturer.
−
Use a soft, damp brush and take care not to scratch the surface of the light ports.
Lubrication
Once the instrument has been disinfected, cleaned and is dry (free from residues), it must be lubricated before, and not after sterilization.
Follow manufacturer’s instruction for proper lubrication.
4.
Packaging
In order to preserve sterility, rotating instruments should be wrapped prior to sterilization. Follow the
manufacturer’s packing instructions when using sterilization packaging (also see Appendix 2 “Sterilization Load Preparation”).

BOWIE & DICK TEST
The Bowie & Dick (B&D) Test, also called Steam Penetration Test, is representative of the small porous
type load. It comprises several sheets of paper and foam wrapped in a small packet in the middle of which
there is a chemical heat-sensitive indicator strip (physic-chemical test).
This test is used to validate the equipment performance in terms of textile load sterilization, that is:
-
Pre-vacuum efficiency and thus steam penetration
2.16
Pressure (Bar)
Temperature and pressure parameters of
the saturated steam achieved during the plateau/holding time.
The Bowie & Dick Test cycle profile is identical to
the ones of the B-UNIVERSAL 134 and the BPRION 134 cycles with the following differences:
-
Time
The sterilization plateau is 3 minutes 20
seconds guaranteeing a 30 seconds security
margin.

HELIX TEST
The Helix Test is representative of the type A hollow load
(EN 13060). It consists of a 1500 mm long tube that is open
on one side and closed with a capsule on the other side. An
indicator strip is placed inside of the capsule.

APPENDIX 7
WATER QUALITY
W&H Lisa sterilizers use distilled or demineralized water to generate steam for the sterilization process.
Water quality sensors constantly monitor the quality of the water used for sterilization as water of too high
mineral content can seriously damage the sterilizer and impair the sterilization process.
The total mineral content of water used for sterilization has to be lower than 10 ppm (parts per million) or if
a conductivity meter is used to check the water quality, the conductivity has to be lower than 15 µs/cm.
The table below lists the water quality to be used for steam sterilization (see EN 13060 APPENDIX C).
Contaminants of feed water
Values
Evaporate residue
< 10 mg/l
Silicon oxide, SiO2
< 1 mg/l
Iron
< 0,2 mg/l
Cadmium
< 0,005 mg/l
Lead
< 0,05 mg/l
Rest of heavy metals, excluding iron, cadmium, lead
< 0,1 mg/l
Chloride
< 2 mg/l
Phosphate
< 0,5 mg/l
Conductivity (at 20°C)
< 15 µs/cm
pH value
5-7
Appearance
colorless, clean, without sediment
Hardness
< 0,02 mmol/l
If the sterilizer generates a display message in regards to low water quality, check the water source (refer
to the water treatment system user manual; replace resin cartridge etc.). In case distilled or demineralized
water is purchased from the market, switch to a brand of better quality.
The use of water with a conductivity greater than 15µS/cm may affect the sterilization
process and damage the sterilizer (EN 13060). A conductivity greater than 50µS/cm
may strongly affect the sterilization process and seriously damage the sterilizer.
The use of water for steam generation with contaminants at levels exceeding those
listed in the table above, can greatly shorten the working life of the sterilizer and void
the manufacturer's warranty.
