Hot-air sterilization program
10.15.
The unit has been calibrated by the manufacturer in accordance with applicable norms.
The temperature shown on the display corresponds with a great accuracy to the temperature
in the geometrical centre of the chamber. For the correct operation of the unit it is not necessary to
use user’s calibration.
The user is performing temperature correction
on his own responsibility
and he must be aware of
consequences of changing of manufacturer’s settings. If the equipment was calibrated, calibration
certificate loses its validity.
Before starting hot-air sterilization:
the entire interior must be
clean and dry
. No residue of e.g. samples, plastic or water can
remain inside the chamber,
empty the water pan (the rack, shelves, water pan and CO
2
sensor can stay inside
the chamber),
close the inner glass door and the outer chamber door.
During hot-air sterilization do not touch the internal components and glass door, as there
is a risk of burns. Use protective gloves to avoid burns from hot components.
First sterilization processes may cause an odour. It is not a quality defect. It is recommended
to ventilate the room well during sterilization.
