  • Page 11: Selection Of Language And Type Of Degree

    AESi/23 SELECTION OF LANGUAGE AND TYPE OF DEGREE The control panel of the autoclave gives the possibility to display the steps of each cycle and messages in different languages, which are: SPANISH, CATALAN, ENGLISH and FRENCH. The default language of the autoclave is ENGLISH. Similarly the apparatus offers the possibility the change the type of degree to be used, which are: DEGREE CELSIUS and DEGREE FAHRENHEIT.

    AESi/23 Selector for PC or printer connection To use the printer (ref. IT) after the PC, remember to change the selector and to disconnect the communications cord from the PC. SOLID/LIQUID AND AGAR MODE If the autoclave is not equipped with an accessory reference: PT-2 (Heart probe), when a program is edited it will be set: SOL/LIQ-1 to sterilize solids or liquids or AGAR-1 to sterilize a culture medium.

  • Page 13: Start Up Instructions

    Connect the autoclave to the mains and switch on by pressing the main button (7). At the microprocessor screen will be displayed the message: “RAYPA Sterilclav-Blue” and a few seconds later will appear a number of a program (it will always be the last program used).
  • Page 14 AESi/23 Make sure that the tap (1) (drain valve) is correctly closed (turning the handle 1/4 clockwise). Take care that the water don't overflow the lower grid. Put in the autoclave the materials to be sterilized, directly or with baskets, in a way that you leave space to the steam to circulate freely.

    AESi/23 - CALIBRATION PORT To access the calibration port, remove the screws from the rear cover and remove the 1/2" cap (see image below, fig.3) with an allen key to have a free 1/2" hole. It is very important to use a watertight fitting to pass the corresponding probes as the port is in direct contact with the pressure vessel.
