Page 10: Description Of The Internal Water Tanks
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. -
Page 11: Chamber Rack
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);... -
Page 12: Installation
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. -
Page 13: Electrical Power Supply
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. -
Page 14: Lisaware - Connecting The Sterilizer To A Computer (Optional)
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. -
Page 15: Automatic Water Supply
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. -
Page 16: Getting Started
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. -
Page 17: Initial Warnings And Sleep Mode
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. -
