Replacing the Temperature Safety Thermostat

The autoclave is supplied with a temperature thermostat, which protects

the heaters and autoclave against overheating, during the dry cycle.

This device reconnects automatically when the chamber cools down.

Caution

Before starting, disconnect the instrument from the power source and

ensure that there is no pressure in the autoclave.

Allow the autoclave to cool before removing outer covers.

The temperature safety thermostat is located on the lower side of the fuse

and socket panel on the rear of the autoclave.

1.  Remove the rear cover.
2.  Loosen the heating band.
3.  Unscrew the thermostat and replace it with a new one.
4.  Perform any dry cycle to verify that the

temperature safety

thermostat disconnects the heating units.
