PART 2 DESCRIPTION
2.19 The overall time for the cycle is not fixed and
depends on many factors such as the supply voltage,
the load and the ambient temperature. However, the
controller will ensure a satisfactory sterilization cycle
even when these factors vary over wide ranges.
2.20 If a cycle employing a drying phase is selected,
operation to the end of the sterilizing phase is as
described above. After discharge of steam and water
back into the reservoir, however, the display ‘dry’
appears accompanied by a rapid intermittent audible
signal over a two second period to indicate the beginning
of the drying phase. At this point the operator should
first open the chamber door then push it towards the
closed position again until it just rests lightly against the
door safety catch. This leaves a sufficient gap to allow
vapour to escape.
2.21 The drying phase is about 17 minutes long
during which the heater is operated at low power.
Operation of the heater thermostat is quite normal
during this period. At the end of the drying phase the
display ‘End’ will appear for approximately 10 seconds
followed by ‘ready’, assuming that the door has been
opened as described in section 2. 20.
