Close the lid of the sterilization chamber by turning it clockwise and lifting the safety lever. FVA/A1 - OPERATION AND MAINTENANCE MANUAL Figure 6.4.3.f � Lock the lid of the chamber by inflating the safety gasket, by pressing the dedicated icon of the touchscreen. The message CLOSED is displayed on the touch-screen. 6.4.4. PROGRAM START AND RUN � Enable selection of the sterilization program by pressing the dedicated icon on the touch-screen of the operator panel. The touch-screen displays the list of available programs (up to 10) (5 programs per page, page changing selectable by means of the arrow key); � select the chosen program by pressing the dedicated icon of the touch-screen (icons 1 to 10); � a screen for customizing the selected program is displayed, allowing to add notes referred to the process or to the product to be sterilized; � when the notes have been entered, press the dedicated icon (arrow) to proceed to the cycle start menu. � NOTE Please refer to the technical manual of the machine for the configuration/modification of program parameters. � Start the sterilization cycle by pressing the START icon on the touch-screen. The machine performs sequentially a series of phases, which are displayed on the touch-screen. � NOTE The displayed phases depend on the hardware configuration of the machine and on the setting of the chosen software. Please refer to the technical manual of the machine for the characteristics of the standard phases and of the phases that can be enabled. � At the end of the sterilization program, the machine emits an acoustic signal; by pressing the STOP icon on the touch-screen (STOP), the Fedegari logo is displayed. The operator accesses the main menu by touching any point of the touch-screen. 6.4.5. PRODUCT UNLOADING � From the main menu, press the touch-screen icon that indicates door opening in order to deflate the sealing gasket of the lid of the sterilization chamber; � lift the safety lever, which disengages the lid from the mechanical locking system; � open the lid by turning it counterclockwise.

FVA/A1 - OPERATION AND MAINTENANCE MANUAL ! WARNING! The opening of the lid of the sterilization chamber at the end of a cycle can be accompanied by the release of steam. Moreover, the internal parts of the chamber may remain at high temperature. Be particularly careful during unloading of the sterilized product and use adequate protective means. Removing bottles with an internal temperature that is still above 70°C may cause them to explode, with severe risks for the safety of nearby operators. For this purpose, in order to sterilize solutions contained in sealed bottles, select only sterilization processes with an appropriate final load cooling step and a counterpressure of sterile air that give assurances of safety during load extraction. The safety temperature above which the lid cannot be opened must be set to a value lower than 70°C and the “final check” parameter must be activated by setting the value 1. 6.4.6. SHUTDOWN � Remove power from the machine by turning counterclockwise the main switch (from the ON position to the OFF position). � NOTE Before deactivating the machine remember to enter the STAND-BY password (0000): From the main menu: (Fedegari logo): � press the dedicated icon (Key) of the touch-screen to enter the password management menu; a keypad is displayed, allowing to enter the chosen password; when entered, enable the password by means of the confirmation icon. 6.5. “PHASE STEP” AND “CYCLE STOP” FUNCTIONS During the execution of the sterilization program and until the process ends, normal operating interaction is disabled. It is nonetheless possible to act on the process in progress by activating specific functions (PHASE STEP and CYCLE STOP), which are described here. PHASE STEP function This function is activated by pressing the dedicated icon (descending steps) on the touch-screen. This allows to force the transition to the next operating phase, blocking the commands and actuations related to the operating phase in progress, without waiting for the preset phase end value to be reached, displaying and printing the “MANUAL PHASE-STOP” alarm. � NOTE The PHASE STEP function is not active during the SPONTANEOUS COOLING and AIR COOLING phases: CYCLE STOP function This function is activated by pressing the dedicated icon (exclamation mark) on the touch-screen. This allows to enter the emergency phase, from which, by pressing the dedicated STOP icon on the touch-screen, the atmospheric pressure balancing phase begins automatically, displaying and printing the “MANUAL PHASE-STOP” alarm. ! WARNING! Use of the Phase Step and Cycle Stop functions is extremely dangerous for the load if, during the sterilization of liquids in hermetically-sealed containers, suddenly reaching atmospheric pressure would cause a pressure differential that is dangerous for the containers. Even in the case of containers that are not closed hermetically but are protected by filters, the pressure differential would cause the liquids to boil. Therefore, activate the Phase Step and Cycle Stop functions after making sure that the pressure in the chamber has reached atmospheric values spontaneously and that the temperature of the product is lower than 70°C.
