Safety Systems

11.1 Safety pressure switch
When an abnormal over pressure is produced in the sterilization chamber, the
safety pressure switch acts in a way to stop the autoclave and it opens the
aeration electrovalve.
11.2 Safety valve
If an abnormal over pressure is produced, the safety valve is opened, expelling
the steam.
CAUTION: the steam valve must be oriented in a direction that can
not reach the personnel.
This valve is calibrated to initiate the opening between 2.2 kg/cm² and 2.5
kg/cm².
In case of safety valve reset, the machine must be prepared to advise tech-
nical personnel.

11.3 Safety thermostat

When there is an abnormal temperature rise or a significant decrease in the
water level (with consequent overtemperature in the steam generator), the
safety thermostat will start to stop heating.
In the 150L model, the thermostat must be reset to restart the cycle. To reset
the thermostat, press the white button, then a click will be heard (see attached
photo). A message will appear on the screen.
11.4 Unblocking the door
In case of open lid blocked by a safety system failure make as follows:
1 Stop the machine.
2 Disconnect the machine from the mains.
3 Place an outlet and a tube in the aeration valve.
4 Carefully open the valve to avoid steam leackages. Be careful to avoid
possible burns.
5 Wait for the total steam emptying.
6 Extract the upper cover where display is located in order to put it aside
(it is not necessary to disconnect any wire). It does not use screws, pull
tightly.
7 Remove the plastic cap and pull slightly until the lever is released.
