5.4 Using the E 28 for hot-air sterilization
Sterilizing load: Instruments, glass and glass instruments, syringes (no synthetic material or surgical
cotton wool).
Sterilizing temperature: 180 °C / 356 °F.
Sterilizing time: Unless laid down by special organizations of your country, we recommend 30 minutes
after reaching the sterilizing temperature. When using sterilizing boxes, the sterilizing time must be
increased by another 15 - 30 minutes.
Due to the special demands of the Medical Device Directive (MDD), these ovens are not
qualified for sterilization of medical devices as defined by directive 93/42/EWG.
6. Temperature safety device class 1 (option)
The chamber can be optionally equipped with a temperature safety device class 1 acc. to DIN 12880. It
serves to protect the chamber and prevents dangerous conditions caused by major defects.
This option permits unsupervised operating of the device.
If the nominal temperature is exceeded by about 25 degrees, the over temperature protective device
permanently turns off the chamber.
When the chamber has cooled down, you can turn on the heating by pressing the reset button at the
back of the chamber. If the heating elements turn off repeatedly, have a specialist investigate and remove
the reason of the failure. The reset button is located on the chamber rear, at the bottom right side.
If the temperature safety device acts repeatedly, please contact an authorized service or
BINDER Service.
