These temperatures and times relate of course to load temperatures and the aim in setting a
cycle should be to achieve one of the above criteria in the coldest part of the load. Some loads
however are sensitive to elevated temperatures for prolonged periods, making full
achievement of the above impractical. However the disinfection of such loads after a short
cycle, without necessarily reaching full Sterilising Temperature, is usually sufficient for most
purposes.
Should you require a more precise method then the optional Load Sensed Process Timing
may be of assistance for certain load types. If your autoclave is fitted with this option please
refer to the description later in this manual.
Since there is a time and temperature 'lag' between the temperature controller probe and the
load, this should be compensated for either by increasing temperature or process time, or by
including in the cycle a period of free steaming with the vent open at 100
achieved by pressing in the vent button manually and releasing it manually. Alternatively, the
Automatic Free-steaming function will perform this function automatically if the option is
selected.
If you have an interest in any of the options mentioned above, which can quite easily be retro-
fitted, please contact Priorclave Technical Services Department.
In conclusion, when setting up the autoclaving cycle a large safety margin should be allowed
within the settings.
More precise settings can be assessed by carrying out a 'worst load' test. (See commissioning).
Setting the process time
The process timer can be set to a time up to 999 minutes. The time
required is set by simply using the time up/down buttons. The set
time is displayed until the set temperature is reached, then the
process time begins counting down to zero in increments of one
minute.
Setting process temperature
Pressing either the up or down button momentarily causes the
current set temperature to be displayed. Subsequent use of the
up/down buttons changes the set temperature. If no keys are
pressed for a short time, the display returns to showing the current
chamber temperature.
Selecting other functions
The function select keys may be used to switch the Timed Free-steaming, Cooling, Media
Warming Option, and optional functions such as Load Sensed Process Timing and vacuum
cycles, on or off at any time other than when a cycle is running. An indicator illuminates to
show that a function has been selected. If an option is not fitted (or permitted in the selected
program in multi-program memory models) pressing the appropriate key will result in a visual
and audible fault being signalled and the function will not be selected.
