Priorclave Manual 27125322-EN Issue 2
expected will indicate entrapped air in the autoclave.
If for any reason the temperature is forced outside of a pre-set band, or power to the
autoclave is removed during the process time, the cycle will abort and the fault indicator will
illuminate and a fault code of either F005 or F006 will be shown in the temperature indicator.
This is to ensure that loads that have not been subjected to the required cycle parameters are
not assumed to have been processed correctly. The fault condition is cancelled by:
If no setting lock keyswitch is fitted:
pressing the reset button on the top panel on the right hand side of the autoclave,
or
If a setting lock is fitted:
turning the setting lock key to the enable position and then to the disable position. If the
lock was in the enable condition when the fault occurred, then it must first be turned to
the disable position.
Cooling
12.
After completion of the process time the autoclave moves into the cooling part of its cycle,
and this is shown on the cycle status indicator in blue. If Cooling has been selected this will be
switched on automatically according to the cooling strategy selected. Otherwise cooling will
be by convection.
If there is a power fail while the autoclave is in the cooling part of the process the cycle will
resume in the cooling phase once power is restored.
If the power should fail before sterilisation is complete then the cycle will be stopped.
Thermal lock
13.
Under normal circumstances the autoclave cannot be opened until the temperature of the
load simulator probe, which has a cooling rate assimilated to a bottle of fluid, has fallen below
o
80
C at which point the yellow bar on the cycle status indicator will illuminate. The
temperature shown by the temperature indicator will be significantly below 80
measures the temperature in the open chamber space. Pressing the door button before the
thermal lock has released causes a fault to be signalled. The temperature at which the thermal
lock operates is factory set. This can be reset but must only be done following commissioning
by qualified personnel. The thermal lock can be overridden using the key-switch on the
control panel. The keys for this switch are provided in this manual.
Overriding the thermal lock will cause the main vent to open. Great care should be
exercised when using the key-switch since liquid loads could boil over if vented at elevated
pressures.
There are circumstances, however when quicker access to the load is required. When this is
necessary, first abort the cycle by pressing the start button. Then turn the key into its
horizontal position and holding it in this position, press the door button and wait while the
Hold message is displayed until the door lamp illuminates. Finally press the door button to
release the door lock. The thermal lock key can now be released. If the key is released before
this stage then the Hold display will not reset and the autoclave cannot be opened. To reset
the display, repeat the above procedure and open the autoclave.
Great care should be exercised when using the Thermal Lock Override, especially with liquid
loads. Even at temperatures below 100
be safe. For the above reasons only responsible personnel should keep the Thermal Lock
Override key in a safe place away from the autoclave.
