thermostat of the jacket heater
The autoclave is equipped with a temperature thermostat, which protects the
heaters and the 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.
1. Remove the outer covers of the autoclave.
2. Open the insulation cover.
3. Loosen the jacket heating band screws
4. Unscrew the chamber heaters.
5. Take out the Jacket cut-off thermostat (1)/ PT100 temperature Sensor
(2) of its seat and replace it with new one.
6. Disconnect the cut-off thermostat connector from the chassis / PT100
temperature Sensor connector to the control panel.
7. Reconnect the cut-off thermostat connector to the chassis / PT100
temperature Sensor connector to the control panel.
Note: Make sure that the sensor protrudes for the same length as the replaced
