Turn on the main switch
• The top display shows the time.
• The central display indicates the
OFF state.
• The lower display shows the date
and month.
Press the POWER switch
• The device switches on and
performs a self-diagnosis.
• Wait for the beep to indicate the
end of the self-diagnosis.
At the end of self-diagnosis, the
display shows the current time and
the temperature values and pressure
of the chamber.
If the chamber temperature is below
35 °C, the indication LOW appears on
the display.
Load the chamber and close the door
Maximum load:
• Non-porous: 4 kg
• Porous. 1.5 kg
Loads greater than the maximum
can compromise the result of the
sterilisation.
Check the LED indicators for the
tank water levels
Ensure that the following are not lit:
• Minimum level indicator for the
demineralised water tank;
• Indicator for the contaminated
water tank;
Do not use tap water. Poor quality
water leaves deposits and/or
encrustations and compromises the
proper functioning of the autoclave.
If necessary, fill the water tank
until the maximum level LED
indicator comes on. Use only <15 μs
demineralised water.
