The types of loads that can be sterilized with Lisa sterilizers are described in Table 1 of the reference tech- nical norm EN 13060. These loads include solid, porous, hollow loads type A and hollow loads type B, un- wrapped, single wrapped and double wrapped.
SYMBOLS DISPLAYED ON THE STERILIZER Consult this table whenever one you see one of these symbols in this manual or on the sterilizer. ATTENTION Where this symbol is displayed on the sterilizer, the user must refer to this document. When shown in the user manual this symbol means ATTENTION IMPORTANT NOTES.

DESCRIPTION OF THE INTERNAL WATER TANKS The sterilizer is equipped with two independent water tanks, one for clean water and one for used water. 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.
The chamber usable space is the maximum volume of the chamber for accommodating a sterilization load. This volume is equivalent to a pipe with the following dimensions: Lisa 517 195 x 195 x 297mm (WxHxD); equal to the volume of 11.5 litres Lisa 522 195 x 195 x 390mm (WxHxD);...
The maximum weight of the sterilizer with a full clean water tank and the chamber fully loaded is: 52 kg (Lisa 517) 63 kg (Lisa 522) Leave a gap of 50mm in the back and 10mm on each side of the sterilizer to ensure adequate ventilation.
Select the printer type (§ 6.1.3). LisaPrint is the default setting (Print-p). All necessary data to document sterilization cycles is automatically printed (for details see Appendix 8). NOTE: Lisa 517/522 sterilizers offer the option to digitally save cycle data on removable memo- ry cards.
LISAWARE - CONNECTING THE STERILIZER TO A COMPUTER (optional) Connect up to four Lisa 517/522 sterilizers to a computer or computer network with LisaWare, a computer software that allows automatic saving of cycle data on a computer and the remote monitoring of the cycle progress on the computer screen.
AUTOMATIC WATER SUPPLY Your sterilizer can be connected to an external water supply system and to a continuous drain line. Once connected, the clean water tank will be automatically filled when empty, and the used water will drain con- tinuously. Thus, neither manual filling nor draining are required. The water supply system must deliver de- mineralized water meeting the requirements as listed in Appendix 7.
GETTING STARTED THE USER INTERFACE To power the sterilizer press the main switch located behind the service door (see image to the left). When the sterilizer is switched ON, the chamber automati- cally heats to 120° C. This process (pre-heating) takes approximately 10 minutes. If a sterilization cycle is initiated during the pre-heating phase, it will start automatically once the pre-heating tem- perature is achieved.
INITIAL WARNINGS AND SLEEP MODE This message will appear if the sterilizer is switched on and the clean water tank is empty. Fill the clean water tank with distilled or demineralized water (see § 5.4). If this message is displayed it is not possible to initiate a sterilization cycle. The mes- NOTE: sage disappears automatically once the clean water tank is filled.
FILLING THE CLEAN WATER TANK 5.4.1 Manual filling Use only high quality distilled or demineralized water (see Appendix 7). • Slide the tank cover to the right to access the clean water tank inlet. • Remove the cap (1) from the tank inlet. •...

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 are off, potentially affecting the sterilization efficien- cy, the cycle is immediately interrupted and an alarm message is displayed.
ALARM CODE TABLE Refer to the table below for troubleshooting assistance in case the sterilizer generates an alarm code. Code Description Action Power supply The load cannot be considered sterile. The cycle Power failure or significant drop in voltage occurred A010 must be repeated.
Page 52
Code Description Action Vacuum pump During a vacuum phase of the cycle, a vacuum of A310 –0.20 bar or lower could not be achieved. Clean, check or replace the door seal (§11.2) and the face side of the chamber; repeat the cycle. If the problem persists service.
MAINTENANCE There are two levels of maintenance: Maintenance performed regularly by the user. Maintenance carried out by authorized service technicians (see § 11.10). Before carrying out any maintenance on the unit, remove the mains cable. 11.1 MAINTENANCE PROGRAM Certain consumables have to be replaced periodically to guarantee a faultless operation of the sterilizer. Display messages will inform you whenever it is time to replace one of these components.
11.2 CLEANING THE DOOR SEAL ATTENTION! Operation to be carried out when the sterilization chamber is cold Clean the door seal and the chamber face side with a non ab- rasive cloth and a mild detergent solution. Rinse with clean wa- ter.
11.5 CLEANING THE EXTERNAL STERILIZER SURFACES • Disconnect the mains cable. • Never use disinfectants or abrasive products. • Clean all external covers with a damp cloth and a mild detergent solution. • Do not use excessive amounts of water to wash the sterilizer as this may damage the electrical components and safety mechanisms.
11.8 CLEANING THE WATER TANKS • Disconnect the mains cable. • Completely drain both tanks (see § 5.5). • Leave the drain tube attached to one of the drain quick connectors. • Turn the 5 screws of the tank cover a ½ turn counter- clockwise with the use of a screwdriver (or coin;...
11.9 REPLACING THE DOOR SEAL ATTENTION! Operation to be carried out when the sterilization chamber is cold • Fully open the chamber door of the sterilizer. • Pull out the used door seal by hand. • Carefully clean the seal seat and the chamber face side with a cotton swab moistened with isopropyl alcohol.
11.10 SERVICE CONDUCTED BY AN AUTHORIZED SERVICE TECHNICIAN Regular service is imperative to ensure continuously effective sterilization. LISA 517/522 Sterilizers require servicing every 4000 cycles or 5 years by authorized service technicians. The service includes replace- ment of consumables and other important internal components, a safety and system check as well as tho- rough cleaning of areas that cannot be accessed by the user.
USE OF THE MEMORY CARD Lisa 517/522 sterilizers come with a digital cycle data recording system. Cycle data is automatically saved on a removable/rewritable memory card. Data from memory cards can be managed with your PC or MAC. Memory cards are supplied with a USB cable and an external USB reader.
Each cycle report is saved as a file in a HTM format. File names are generated automatically. Example of a file name: 01898 28-01-06 08_41_22 B&D _ HELIX LISA 517 02-0005.htm saving format depends on the Date-Clock setting (see § 6.1.10 and 6.1.11) 12.8 DIRECTORY NAME...
12.9 MEMORY CARD MANAGEMENT As soon as a memory card is inserted the unit automati- cally checks the card. In case the recorder detects that the memory card is damaged or defective, the following screen is shown. Confirm Press the “Confirm” icon and replace the card. If the card is not formatted or if it is formatted with a dif- ferent standard (e.g., FAT 12) the following screen is shown.
If the “Confirm” icon is pressed the formatting begins. During formatting the system also checks for errors. If it detects any errors the following screen is displayed. Press the “Confirm” icon to return to main menu and replace the card. Confirm 12.10 SAVING A FILE If a memory card is inserted, cycle data is saved automati-...
