3.4 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 automati-
cally 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 pur-
poses (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).
NOTE: The water consumption per sterilization cycle varies depending on the type and weight of the
sterilization load. The capacity of the clean water tank is sufficient to run 8 - 12 sterilization cy-
cles.

4.4 LABEL PRINTER (optional)
We recommend using the printer TLP 2824 (conforms with norm CEI 61010-1) which
has been tested and is compatible with the Lisa sterilizer and its software.
The use of other printers removes all responsibility from the manufacturer with re-
gards to the correct functioning of the system, the guarantee and all other claims.
- Please refer to the label printer manual or
quick-start guide for instructions on how to
mount the roll of labels and ink ribbon.
- Connect the hardware key to the serial port
at the back of the printer.
- Connect the serial cable between the hard-
ware key and the serial port at the back of
the sterilizer.
- Plug in the printer’s power cable at the
mains supply.
- Switch on the printer by pressing the main
interrupter on the right-hand side.
- Select the type of printing (automatic or
manual) and other options in the sterilizer
sub-menus.
- After installation, the printer automatically
carries out calibration to obtain the format of
the labels used. For this to take place, the
label printer must be connected, switched
ON with the label roll and ribbon inserted.
Access the setup menu, select the label
printer option, and select the printer model
to be used (see 6.1.4).
Carry out the selection procedure to cali-
brate the printer, even if the printer is al-
ready set to the correct model.
During calibration, the printer may use up a
few labels, but this is perfectly normal and
these labels can be disposed of.
If the calibration process has not been car-
ried out correctly or it has been carried out
correctly but the label format does not cor-
respond to that selected for the application,
the printer may present anomalies during
printing such as blocking, leaving blank la-
bels or printing only partial information etc.

11
4.5 DEMINERALIZER (optional)
W&H Sterilization offers external water supply systems for automated supply of demineralized water to the
sterilizer(s) (LisaDem32 or LisaOsmo). Once installed, the clean water tank no longer needs to be filled
manually but will be filled automatically with demineralized water. The LisaDem32/LisaOsmo utilize resin
cartridges to remove minerals from city water to assure a constant good water quality for the sterilization
process.
4.5.1 Connecting an external water supply system (demineralizer)
To install a LisaDem32/LisaOsmo water supply system,
an interface cable and the fittings D2 and D4 located at
the back of the sterilizer are used.
For more information, refer to the LisaDem32/LisaOsmo
user manuals.
4.6 CONTINUOUS DRAINING (optional)
4.6.1 Connecting the drain tube
The sterilizer can be connected to a drain (or simply to a
sink) for continuous draining of the used water.
-Unscrew the plug from the D4 fitting at the back of
the sterilizer.
-Install the 1/8” barber fitting and the drain tube from
the kit and route the tube to a drain or sink (kit or-
dering number: G0053060). If unclear, have the in-
stallation checked by a qualified plumber.
The drain tube must not be longer than 5
meters.
The draining point must be at least 20cm
below the surface on which the sterilizer
is placed.
For further information, refer to the LisaDem32/LisaOsmo
user manuals.

The water level in the clean water tank decreases during every sterilization cycle, while the used water
tank level is rising. The sterilizer is equipped with an internal water conductivity sensor that constantly
monitors the water quality. Should the water quality go beyond a maximum threshold (>15µS/cm con-
ductivity), a warning message is displayed on the screen.
Every time you fill the clean water tank drain the used water tank (see § 5.5).
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 screen-
shot to the right).
Water of low quality can impair the sterilization process and seriously damage the in-
ternal 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.
