Closure Of The Door; Residual Risk - Zhermack zetaclave B Manual De Uso Y Mantenimiento

MAINTENANCE AND USE MANUAL
Keep the door pushed in until the display shows the door locked icon.
To close the door, it is NOT necessary to press the START button as the motor starts
automatically. To start the cycle, press the START button once the door is closed.
The purpose of the test cycle is to ensure that the autoclave is in working order, has not suffered any
damage during transport and is not subject to any operational faults due to technical causes. It is
recommended that this test is based on BOWIE & DICK cycle.
• Close the door and press the button START (please to read point 7.3.1)
• BOWIE & DICK: While the cycle is running, the display will show the temperature – pressure– time
remaining– selected cycle number – type of cycle - current cycle phase - any warning icons. Insert the
tray holder and the trays inside the machine as indicated at paragraph 11.1. The vacuum pump starts
removing air from the chamber until the preset value is reached (VACUUM 1), after which the rise
phase will start (PREHEATING). During this phase a slight buzz coming from the water injection pump
(used to inject steam into the chamber) can be heard. Once the preset vacuum degree is reached the
EXHAUST phase will start; on completion, another two vacuum phases and two preheating phases
will be carried out until the cycle preset values are reached (paragraph 10). The STERILISATION phase
will now start. during the exposure period, pressure and temperature will be continually software-
controlled to ensure that the sterilisation is successful. Alarms will trip in the event of problems (see
paragraphs 13 and 13.1).
On completion of the sterilisation phase, the DRYING phase will begin: pressure inside the chamber
will be released and the final vacuum phase will start (the pump will suck any steam to considerably
improve the final drying of the sterilised instruments). The door can only be opened when the display
shows END CYCLE. In the event of residual positive or negative pressure, the door lock system will not
open (proceed as indicated in paragraph 3.3.1, DOOR and PUMP).
Remove the instruments by using the special handle supplied with the equipment: use protective
gloves to avoid getting burnt.
Residual risk is:
• a danger that cannot be completely eliminated through design and application of safety devices.
• a potential danger which cannot be highlighted.
To prevent accidents always observe the instructions in this manual. Should you have
any doubts at all please contact the Manufacturer or your Authorised Servicing
Centre.
The above-mentioned dangers are indicated by special labels attached to the equipment, as
described in sub-section 3.4.1.
